Description

Technical Field

[0001] This invention belongs to the field of toxic gas purification technology in blasting operations, specifically a deep-hole blasting charge structure, an integrated delivery device, and a method for efficient CO removal. Background Technology

[0002] During mine operations, when encountering hard rock strata or fault lines, deep-hole blasting is typically required to meet on-site operational needs. Since deep-hole blasting holes in mines are usually 20-40 meters deep, individual explosive cartridges or shaped charge tubes need to be pushed to heights of tens of meters. To achieve this, on-site operators need to connect multiple blasting rods together to complete the pushing action. Currently, this is done manually, requiring approximately 6-8 on-site personnel working together to complete the entire process. Therefore, this method is resource-intensive, inefficient, and inherently dangerous, and is clearly no longer suitable for current operational needs.

[0003] Furthermore, during deep-hole blasting operations, the generated toxic CO gas is also released into the roadway, easily leading to excessively high CO concentrations in the roadway after blasting, which poses a serious threat to the workers inside. Currently, local ventilation is the conventional method for dealing with CO in deep-hole blasting operations. Local ventilation mainly uses local fans and ventilation ducts to deliver air to the working face to dilute CO. However, this ventilation method dilutes CO extremely slowly and cannot quickly eliminate the source of CO. Therefore, there is an urgent need for a method that can efficiently eliminate CO in deep-hole blasting, while also effectively reducing manpower consumption to ensure the life, health, and safety of blasting workers and significantly improve the efficiency of blasting operations. Summary of the Invention

[0004] To address the problems existing in the prior art, this invention provides a deep-hole blasting charge structure, an integrated delivery device, and a highly efficient CO elimination method. The charge structure can effectively eliminate CO in segments and also provides flame and smoke suppression for the generated open flames and dust, achieving a three-in-one effect of in-situ CO elimination, flame suppression, and smoke suppression within the blast hole. The device can efficiently perform deep-hole filling operations, significantly reducing the workload of operators and effectively saving manpower and resources. The method is simple to implement and can eliminate the toxic and harmful CO gases generated during deep-hole blasting operations at the source. Simultaneously, it effectively reduces the construction difficulty and workload for deep-hole blasting personnel and significantly improves the efficiency of the filling operation.

[0005] To achieve the above objectives, the present invention provides a deep-hole blasting charge structure, including a pre-set blasting hole, a blasting unit, an upward check mechanism, and columnar sealing mud.

[0006] The preset blasting hole is divided into a blasting section and a sealing section from the inside out; the outer diameter of the blasting unit is smaller than the inner diameter of the preset blasting hole, and it includes a shaped charge tube, a fastener, a first charge tube and a second charge tube.

[0007] The shaped charge tube includes a shaped charge tube body, an anti-slip mechanism, and explosive cartridges. The shaped charge tube body is a tube open at both ends, with at least one shaped charge band along its length. The shaped charge band consists of several shaped charge holes evenly distributed along its length. Two anti-slip mechanisms are installed opposite each other inside the ends of the shaped charge tube body. Each anti-slip mechanism includes a rigid frame and a flexible layer. The rigid frame is a ring-shaped hollow frame. The flexible layer is annular, with its inner circular surface fitted onto the outer circular surface of the rigid frame, and its outer circular surface tightly abutting against the inner wall of the shaped charge tube body. Multiple explosive cartridges are sequentially installed inside the cavity of the shaped charge tube body and located between the two anti-slip mechanisms.

[0008] The fastener is a short straight tube with openings at both ends. The middle part is a concave section with an annular shape. Two connecting sections are formed at both ends. The inner diameter of the connecting section is larger than the inner diameter of the constricted section and is adapted to the outer diameter of the energy-concentrating tube. The two fasteners are fitted onto the outside of both ends of the energy-concentrating tube through the connecting sections at their respective ends.

[0009] The first and second charging tubes have the same structure, both including a charging tube body, an anti-impact mechanism, and a CO elimination slurry roll;

[0010] The charging tube is a straight tube with an open end and a closed end, and its outer diameter is the same as that of the shaped charge tube. The anti-impact mechanism and the CO elimination slurry roll are sequentially installed inside the charging tube, with the anti-impact mechanism located at the end of the charging tube. The CO elimination slurry roll is filled with CO elimination slurry for CO elimination. The anti-impact mechanism includes a front support plate, an end support plate, and an elastic component. The front support plate and the end support plate are distributed at intervals, and their edges are respectively provided with a through-wire hole 1 and a through-wire hole 2. The front support plate has several hexagonal through holes 1 evenly distributed on the portion other than the through-wire hole 1. The end support plate has several hexagonal through holes 2 evenly distributed on the part other than the wire through hole 2, and the diameter of the hexagonal through hole 1 is larger than the diameter of the hexagonal through hole 2; multiple elastic components are evenly distributed between the first end support plate and the last end support plate, and their two ends are respectively connected to the first end support plate and the last end support plate. Under the elastic action of the multiple elastic components, the first end support plate and the last end support plate abut against the ends of the CO elimination slurry roll and the charging tube respectively; the first charging tube and the second charging tube are distributed opposite to each other at the ends of the two fasteners that are far apart, and the first end of the charging tube is inserted into the sleeve section of the two fasteners respectively.

[0011] Multiple blasting units are sequentially and adjacently filled into the blasting section, and the second charge tube in each blasting unit is closer to the orifice than the first charge tube;

[0012] The upward check mechanism is installed in the preset blasting hole and is located at the outer end of the blasting section to prevent multiple blasting units from moving towards the hole opening.

[0013] Multiple sections of columnar sealing mud were sequentially filled into the sealing section.

[0014] In this invention, several shaped charge holes are provided on the shaped charge tube body, facilitating directional blasting operations. Multiple sections of explosive cartridges are assembled into the shaped charge tube body, and two anti-slip mechanisms are installed at both ends of the shaped charge tube body. These two anti-slip mechanisms form two limiting structures at the two open ends of the shaped charge tube body, thus preventing the explosive cartridges from detaching from either open end. The anti-slip mechanism consists of an inner rigid frame and an outer flexible layer, with the rigid frame being a ring-shaped hollow frame. This not only provides a limiting function but also allows the blast wire connected to the explosive cartridge to pass smoothly through. Simultaneously, it facilitates the impact force of the explosive detonation to be effectively applied to the charging tube through the anti-slip mechanism. The fastener consists of a reduced-diameter section in the middle and sleeve sections at both ends. This allows for the use of the two sleeve sections at both ends to secure the charging tube and the shaped charge tube, while the reduced-diameter section forms a limiting structure at the ends of the charging tube and the shaped charge tube. One end of the explosive charge tube is opened, and a CO-eliminating slurry roll and an anti-impact structure are inserted inside to form the charge tube. The open end of the charge tube is then inserted into a fastener, creating a CO-eliminating section along the side of the multi-section explosive roll. This ensures that the CO-eliminating slurry in the roll remains intact under the high temperature and pressure conditions generated by the explosive blast. The anti-impact mechanism consists of a front support plate, an end support plate, and multiple elastic components. This provides good buffering capacity, thus offering a certain degree of cushioning for the CO-eliminating slurry roll inside the charge tube during the explosion. This helps prevent the CO-eliminating slurry roll from being pushed away by the impact force at the initial stage of the explosion, and allows it to be torn apart instantly. Furthermore, the high temperature and pressure conditions generated by the explosion allow the CO-eliminating slurry to evaporate rapidly, ensuring timely and sufficient contact with the generated CO gas, achieving efficient CO elimination. By mounting two charge tubes opposite each other at the ends of the shaped charge tube using two fasteners, efficient CO elimination from both sides can be achieved while reducing the amount of CO eliminator used. This significantly improves the CO elimination effect while maintaining in-situ CO elimination capability. Furthermore, since the CO eliminating slurry absorbs a large amount of heat during evaporation, it can effectively reduce the temperature inside the borehole. In addition, the droplet-shaped CO eliminating slurry can help extinguish open flames inside the borehole and carry away some of the generated dust, thus achieving flame and smoke suppression. By installing upward check mechanisms at the ends of multiple blasting units, it is easy to position the multiple blasting units after loading, thereby preventing the blasting units from detaching from the borehole. Filling the sealing section with multiple sections of columnar sealing clay can improve the sealing performance of the sealing section, which is beneficial to improving the blasting effect of the explosive.

[0015] This invention proposes a deep-hole blasting charging structure based on CO-eliminating slurry rolls. Multiple blasting units, consisting of a first charging tube, a shaped charge tube, and a second charging tube, are formed within the explosive blasting section of the borehole. This allows for the formation of two CO-eliminating sections on both sides of the multiple explosive rolls within each blasting unit. Consequently, CO generated by each blasting unit can be effectively eliminated in stages during the blasting process, and the resulting flame and dust can be suppressed to a certain extent. This achieves a three-in-one effect of in-situ CO elimination, flame suppression, and smoke suppression within the borehole.

[0016] Furthermore, in order to facilitate the upward check mechanism to reach the in-hole positioning state through impact triggering, thereby conveniently realizing the check function for multi-section blasting units, the upward check mechanism includes a support base, a guide column, a connecting ring, a second support rod, a first support rod, and a triggering component;

[0017] The support base abuts against the columnar sealing mud; the lower end of the guide pillar is vertically fixedly connected to the support base, and its upper end is used to abut against the blasting unit; the connecting ring is fixedly fitted onto the outside of the middle section of the guide pillar; two second support rods are distributed opposite to each other on both sides of the connecting ring, and their upper ends are respectively hinged to the opposite sides of the connecting ring; two first support rods are correspondingly arranged above the two second support rods, and are distributed opposite to each other on both sides of the guide pillar, with the upper ends of the two first support rods respectively hinged to the upper ends of the guide pillar, and their lower ends respectively hinged to the middle sections of the two second support rods;

[0018] The triggering assembly includes a trigger element, a first elastic element, and a second elastic element. The two trigger elements are fixedly installed on both sides of the lower part of the guide pillar and correspond to the two second support rods. The two first elastic elements are correspondingly disposed above the two second support rods and distributed on both sides of the guide pillar. Their upper ends are connected to both sides of the upper part of the guide pillar, and their lower ends are connected to the upper parts of the two second support rods. The two second elastic elements are correspondingly disposed below the two second support rods and distributed on both sides of the guide pillar. Their upper ends are connected to the middle sections of the two second support rods, and their lower ends are connected to the two trigger elements. When subjected to external impact force, both trigger elements will detach from the two second elastic elements.

[0019] The connecting ring is fixedly fitted onto the middle section of the guide post and hinged to the upper ends of the two second support rods on opposite sides, allowing both second support rods to have a certain swing amplitude. Two trigger elements are installed below the connecting ring, and two second elastic elements are connected to the middle sections of the two second support rods and the two trigger elements respectively, allowing the two second elastic elements to keep the two second support rods in a contracted state. The lower ends of the two first elastic elements are connected to the two second support rods, and the two second elastic elements are connected to the upper ends of the guide post. This allows the two first elastic elements to provide tension in the expansion direction for the two second support rods. Thus, when the two second elastic elements disengage, the two second support rods can quickly reach an expanded state, thereby achieving rapid positioning within the hole. The upper ends of the two first support rods are hinged to both sides of the upper end of the guide column, and the lower ends of the two first support rods are hinged to the two second support rods. The two first support rods, together with the two second elastic elements, can maintain the retracted state of the two second support rods, which is conducive to the smooth loading of the upward check mechanism. At the same time, when the two second elastic elements are disengaged, the two movable first support rods will not affect the expansion action of the two second support rods.

[0020] Furthermore, to facilitate detonation, a detonator is arranged in the blasting unit near the orifice. The detonator is embedded in a section of explosive cartridge near the orifice in the shaped charge tube. The blast wire connected to the detonator extends towards the orifice and, after passing through the anti-slip mechanism, the outer side of the second charge tube, the upward check mechanism, and the edge of the columnar sealing mud, reaches the outer side of the preset blasting hole.

[0021] As a preferred embodiment, the number of CO elimination slurry rolls in both the first and second charging tubes is 1 to 3.

[0022] Furthermore, in order to effectively reduce the amount of CO scavenger used, and at the same time, to improve the CO scavenging effect and efficiency, and to enable the formed CO scavenging slurry to have a certain dust reduction effect, the CO scavenging slurry in the CO slurry roll is composed of CO scavenger, binder, surfactant and deionized water; based on the total mass of the CO scavenging slurry, the mass concentration of the CO scavenger is 5-20%, the CO scavenger is a transition metal oxide composed of one or more elements selected from iron, manganese and cerium, and its particle size is 0.01-0.1 mm; the mass concentration of the binder is 7-28%; and the mass concentration of the surfactant is 0.0001%-0.04%.

[0023] As a preferred embodiment, the propellant tube bodies in both the first and second propellant tubes are integrally molded from flame-retardant materials; the energy-concentrating tube body is integrally molded from flame-retardant materials; and the anti-impact structure and the upward check mechanism are both made of hard metal materials with good corrosion resistance and compressive strength.

[0024] As a preferred embodiment, the length of the propellant tube in the first and second propellant tubes is 1 / 6 to 1 / 4 of the length of the shaped charge tube.

[0025] The present invention also provides an integrated pushing device for completing a deep hole blasting charge structure. The integrated pushing device includes a fixed platform, a rotating bracket, a support platform, a hydraulic cylinder one, a hydraulic cylinder two, a main transmission mechanism, a sliding platform, a push plate, a guide frame, a pushing rod, a limit frame, and an auxiliary transmission mechanism.

[0026] The fixed platform has two pairs of casters installed at both ends of its bottom length direction, and its front top and rear bottom are respectively fixedly connected to a lower hinge seat one and a lower hinge seat two.

[0027] The lower end of the rotating bracket is hinged to the top of the rear end of the fixed platform;

[0028] The support platform is located above the fixed platform. Its rear bottom is hinged to the upper end of the rotating bracket. Its front bottom and rear bottom are respectively fixedly connected to the upper hinge seat one and the upper hinge seat two. The central area of ​​the upper surface of the support platform has a downwardly recessed installation platform along the length direction, and two slides extending along the length direction are provided opposite to each other on both sides of the width direction of the installation platform.

[0029] The piston rod end of the hydraulic cylinder is hinged to the upper hinge seat, and the end of the cylinder barrel is hinged to the lower hinge seat.

[0030] The piston rod end of the hydraulic cylinder 2 is hinged to the upper hinge seat 2, and the end of its cylinder barrel is hinged to the lower hinge seat 2.

[0031] The main drive mechanism is installed in the mounting platform and includes a driven sprocket, a driving sprocket, a chain, a pneumatic motor, and an electromagnetic reversing valve. The driven sprocket is rotatably mounted on the front end of the mounting platform via a front bracket. The driving sprocket is rotatably mounted on the rear end of the mounting platform via a rear bracket. The chain is wound around the outside of the driven and driving sprockets. The pneumatic motor is fixedly mounted on one side outside the driving sprocket, and the drive shaft of the pneumatic motor is coaxially connected to the rotating shaft at the center of the driving sprocket. The electromagnetic reversing valve is mounted on the pneumatic motor. The electromagnetic reversing valve is a three-position five-way reversing valve. When it is in the left position, it controls the pneumatic motor to rotate forward. When it is in the middle position, it controls the pneumatic motor to stop. When it is in the right position, it controls the pneumatic motor to rotate in reverse. The A and B ports of the electromagnetic reversing valve are connected to the A and B ports of the pneumatic motor, respectively. Its R and S ports are connected to the outside atmosphere. Its P port is connected to the air outlet of the connecting pipe. The air inlet of the connecting pipe is used to connect to a high-pressure air source.

[0032] The sliding platform is in the shape of an inverted U, which covers the outside of the main transmission mechanism, and its two ends of the opening are slidably mounted in two slides on the support platform. At the same time, the sliding platform is connected to a section of the chain below.

[0033] The push plate is fixedly connected to the rear end of the upper surface of the sliding platform, and a connecting rod is connected to its front end;

[0034] The guide frame is fixedly connected to the front of the upper surface of the support platform and is distributed correspondingly to the push plate. At the same time, a guide hole is opened in its center.

[0035] The push rod is slidably assembled in the guide hole of the guide frame, and its rear end extends above the sliding platform and is fixedly connected to the connecting rod connected to the front end of the push plate by threads.

[0036] A pair of limit frames are distributed opposite to each other on both sides of the push rod and located on the front side of the guide frame. They are fixedly installed on the top of the support platform. A pair of clamping and positioning mechanisms are connected opposite to each other on both sides of the push rod on the limit frames. The pair of clamping and positioning mechanisms are used to position and clamp or release the push rod by telescopic movement.

[0037] The auxiliary transmission mechanism includes a roller support, a roller, a guide pulley, and a wire rope; the lower end of the roller support is fixedly connected to the upper part of the rear section of the support platform; the roller is rotatably mounted on the upper end of the roller support; the guide pulley is located above the push rod and is rotatably mounted between a pair of limit frames; one end of the wire rope is connected to the front section of the push rod, and the other end is wound around the guide pulley and then connected to the roller.

[0038] In this invention, the upper and lower ends of the rotating bracket are hinged to the supporting platform and the fixed platform, respectively, allowing the supporting platform to have flexible movement space above the fixed platform. The front end of the supporting platform is connected to the front end of the fixed platform via hydraulic cylinder one, and the rear end of the supporting platform is connected to the rear of the fixed platform via hydraulic cylinder two. The telescopic cooperation of hydraulic cylinders one and two allows for convenient adjustment of the tilt angle of the supporting platform, thus accommodating blasting hole loading and sealing operations at different tilt angles. The sliding platform is positioned outside the main transmission mechanism and slides with the supporting platform via a slide rail, ensuring that the sliding process does not affect the operation of the main transmission mechanism. The sliding platform is connected to a section of a chain, allowing the movement of the chain to drive the sliding platform to move significantly along the length of the supporting platform. A push plate is connected to the sliding platform, and a guide frame with guide holes is connected to the front end of the supporting platform corresponding to the push plate. This facilitates the connection of a push rod using the guide frame and push plate, enabling the movement of the sliding platform to drive the telescopic movement of the push rod. A pair of limiting frames are installed on opposite sides of the push rod, and a pair of clamping and positioning mechanisms are connected to the opposite sides of the pair of limiting frames. This allows for easy clamping and positioning of the push rod using the clamping and positioning mechanisms, facilitating both the smooth cascading of new push rods and the step-by-step removal of multiple push rods. A guide pulley is connected between the pair of limiting frames, and the steel wire rope connected to the push rod passes around the guide pulley and connects to the roller located at the rear of the support platform. This allows the guide pulley to be used as a support point, enabling operators to manually pull the steel wire rope to drive the push rod in small-amplitude reciprocating impact operations. The device coaxially connects the pneumatic motor to the drive sprocket, and then uses a three-position, five-way electromagnetic reversing valve to connect the pneumatic motor and the connecting pipeline. This allows for easy connection between the connecting pipeline and the compressed air pipeline, facilitating the transport of filling material inside the blast hole using the on-site compressed air pipeline. This enables filling in deep-hole blasting operations at different inclination angles, making full use of the site environment, reducing the likelihood of electrical equipment use, effectively reducing the number of on-site construction personnel, lowering the risk of deep-hole blasting operations, and improving blasting efficiency. This device can efficiently achieve deep-hole filling operations, significantly reducing the labor load of operators and effectively saving manpower and material resources.

[0039] As a preferred embodiment, handles are fixedly connected to both the front and rear sides of the push plate.

[0040] This invention also provides a method for efficient CO removal in deep-hole blasting, employing an integrated pushing device, comprising the following steps:

[0041] Step 1: Construct pre-drilled blasting holes and prepare blasting units;

[0042] Complete the drilling of the pre-set blasting holes at the designated blasting locations;

[0043] First, the anti-impact structure and CO elimination slurry roll are sequentially loaded into the charge tube body, and the first charge tube and the second charge tube are made in this manner. Second, an anti-slip mechanism is installed inside one end of the shaped charge tube body, and multiple sections of explosive rolls are sequentially loaded from the other end. Then, another anti-slip mechanism is installed inside the other end of the shaped charge tube body to make the shaped charge tube. Next, the connecting sections of two fasteners are fitted onto the outside of both ends of the shaped charge tube. Finally, the open ends of the first charge tube and the second charge tube are inserted into the connecting sections of the two fasteners to make the blasting unit. Multiple blasting units are made in the above manner. For one of the blasting units, a detonator is buried in one section of explosive roll at its middle end, and the blast wire connected to the detonator is sequentially passed through the wire hole one and wire hole two in the anti-slip mechanism, fastener, and anti-impact mechanism on the nearest side, and then through the end of the charge tube body.

[0044] Step 2: Load the blasting unit and the upward check mechanism;

[0045] S21: First, move the integrated pusher to the bottom of the preset blast hole and connect the connecting pipe to the compressed air pipe. Then, fix the position of the integrated pusher. Then, according to the angle of the preset blast hole, control the hydraulic cylinder one and hydraulic cylinder two to extend and retract until the pusher is adjusted to an angle that matches the preset blast hole.

[0046] S22: Install multiple blasting units and an upward check mechanism into a preset blasting hole in sequence, and position the blasting unit with the detonator buried on the side closer to the hole opening, and position the support seat of the upward check mechanism on the side closer to the hole opening. At the same time, lead the blast line out of the hole opening.

[0047] S23: Control the solenoid reversing valve to work in the left position, supply the compressed gas in the compressed air pipeline to port A of the pneumatic motor through the solenoid reversing valve, drive the pneumatic motor to rotate forward, and use the rotating drive sprocket to drive the chain, sliding platform and push plate to move towards the front end of the support platform. At the same time, make the push rod extend outward and into the preset blasting hole, and use the extended push rod to push the upward check mechanism and multiple blasting units towards the bottom of the hole.

[0048] S24: When the sliding platform moves to the maximum stroke position at the front end of the support platform, first control the solenoid directional valve to work in the neutral position, and control a pair of clamping and positioning mechanisms to extend to clamp and position the push rod. Then, the connecting rod on the push plate is disengaged from the push rod. Next, control the solenoid directional valve to work in the right position, and supply the compressed gas in the compressed air pipeline to the B port of the pneumatic motor through the solenoid directional valve. Drive the pneumatic motor to reverse, and use the rotating drive sprocket to drive the chain, sliding platform and push plate to move towards the rear end of the support platform. After the sliding platform is reset, control the solenoid directional valve to work in the neutral position again.

[0049] S25: Install a new push rod on the support platform, and connect the male connector at the front end of the new push rod to the female connector of the previous push rod through a thread, and connect the female connector of the new push rod to the connecting rod on the push plate through a thread.

[0050] S26: Repeat S to S multiple times until the upward check mechanism and multiple blasting units are pushed to the predetermined depth position, and then keep the connection state of the multiple push rods unchanged.

[0051] Step 3: Use the upward check mechanism to locate multiple blasting units;

[0052] The reciprocating steel wire rope is pulled, and the guide pulley is used as a fulcrum to make the front end of the push rod reciprocate to hit the support seat of the upward check mechanism. The impact force generated by the impact triggers the action of two trigger elements, which releases the connection state of the two second elastic elements. Under the elastic pull of the two first elastic elements, the ends of the two second support rods are radially opened outward and clamped on the wall of the blast hole, thereby realizing the positioning of the upward check mechanism in the hole, and using the positioned upward check mechanism to prevent multiple blasting units from sliding towards the hole opening.

[0053] Step 4: Perform hole sealing.

[0054] S41: Multi-section columnar sealing clay is made using yellow clay and a small amount of binder;

[0055] S42: First, by controlling the action of the solenoid reversing valve, the sliding platform is reset to the rear end of the support platform. Then, a pair of clamping and positioning mechanisms are extended to clamp and position the push rod in front of the end push rod. Then, the connection of the end push rod is released and it is removed.

[0056] S43: By controlling the action of the solenoid directional valve, the sliding platform is moved to the front end of the support platform, and then the connecting rod on the push plate is connected to the clamped push rod.

[0057] S44: Repeat S and S multiple times until the number of remaining push rods on the support platform meets the sealing requirements of the columnar sealing mud.

[0058] S45: By controlling the action of the electromagnetic reversing valve, the front end of the push rod is moved out of the preset burst hole;

[0059] S46: First, load the multi-section columnar sealing mud into the preset blasting hole in sequence. Then, control the solenoid reversing valve to work in the left position, so that the push rod extends towards the bottom of the hole. Use the extended push rod to push the multi-section columnar sealing mud to the predetermined depth position. Then, control the solenoid reversing valve to work in the middle position to maintain the pushing state of the push rod.

[0060] S47: The steel wire rope is pulled back and forth, and the guide pulley is used as the fulcrum to make the front end of the push rod reciprocate to hit the outer end of the columnar sealing mud until the columnar sealing mud is compacted, thus completing the sealing operation of the blast hole.

[0061] Step 5: CO removal operations during the blasting process;

[0062] S51: After completing the filling of all the pre-set blasting holes, connect all the lead-out blasting wires to form a blasting network. Then, evacuate personnel to the outside of the safe area and use the blasting wires to detonate the detonators to ignite the explosive cartridges.

[0063] S52: The high temperature and pressure generated by the explosion of the explosive act on the CO elimination slurry in the blasting unit, causing the CO elimination slurry to evaporate and come into full contact with the CO toxic gas to achieve CO elimination. At the same time, the evaporated CO elimination slurry absorbs the high temperature in the explosion space. Furthermore, some of the CO elimination slurry droplets carry away some dust and extinguish open flames, thus achieving CO elimination and dust reduction.

[0064] In this invention, multiple blasting units are assembled within the blasting section inside the pre-fabricated blasting hole, with each unit arranged in a first charge tube-shaped charge tube-second charge tube configuration. This unique deep-hole blasting charging structure allows for the simultaneous elimination of CO gas and dust generated during the blasting process. Furthermore, the segmented elimination of CO and dust generated within each blasting unit significantly improves elimination efficiency and effectiveness. An upward check mechanism is installed at the end of each blasting unit to limit their movement, preventing them from detaching from the borehole during loading. Utilizing an integrated pushing device for deep-hole loading of multiple blasting units, upward check mechanisms, and multi-section columnar sealing mud significantly reduces the workload of operators, effectively saves manpower and resources, significantly improves loading efficiency, and effectively ensures loading quality.

[0065] This method is simple to implement and can eliminate the toxic and harmful CO gas generated by deep hole blasting operations at the source. At the same time, it can effectively reduce the construction difficulty and labor load of deep hole blasting workers, improve work efficiency, and effectively ensure the safety of workers' lives and health.

[0080] The invention will now be further described with reference to the accompanying drawings.

[0081] like Figures 1 to 9 As shown, the present invention provides a deep hole blasting charge structure, including a pre-set blasting hole 1, a blasting unit 2, an upward check mechanism 20, and a columnar sealing mud 19;

[0082] The preset blasting hole 1 is divided into a blasting section and a sealing section from the inside out; the outer diameter of the blasting unit 2 is smaller than the inner diameter of the preset blasting hole 1, and it includes a shaped charge tube 4, a fastener 14, a first charge tube 3 and a second charge tube 5.

[0083] The shaped charge tube 4 includes a shaped charge tube body 9, anti-slip mechanisms 11, and explosive rolls 10. The shaped charge tube body 9 is a tube with openings at both ends, and at least one shaped charge band is provided along its length. The shaped charge band is composed of a plurality of shaped charge holes evenly distributed along its length. Two anti-slip mechanisms 11 are installed opposite each other inside the ends of the shaped charge tube body 9. Each anti-slip mechanism 11 includes a rigid frame 12 and a flexible layer 13. The rigid frame 12 is an annular hollow frame. The flexible layer 13 is annular, with its inner circular surface fitted onto the outer circular surface of the rigid frame 12, and its outer circular surface tightly abutting against the inner wall of the shaped charge tube body 4. Multiple explosive rolls 10 are sequentially installed in the inner cavity of the shaped charge tube body 9 and located between the two anti-slip mechanisms 11.

[0084] The fastener 14 is a short straight tube with openings at both ends. The middle part is a concave annular section 15 with a reduced diameter. Two connecting sections 16 are formed at both ends. The inner diameter of the connecting section 16 is larger than the inner diameter of the reduced diameter section 15 and is adapted to the outer diameter of the energy-concentrating tube 9. The two fasteners 14 are fitted onto the outside of both ends of the energy-concentrating tube 4 through the connecting section 16 at one end of each fastener.

[0085] The first charging tube 3 and the second charging tube 5 have the same structure, both including a charging tube body 6, an anti-impact mechanism 7, and a CO elimination slurry roll 8;

[0086] The charging tube 6 is a straight tube with an open end and a closed end, and its outer diameter is the same as that of the energy-concentrating tube 9. The anti-impact mechanism 7 and the CO-eliminating slurry roll 8 are sequentially installed inside the charging tube 6, with the anti-impact mechanism 7 located at the end of the charging tube 6. The CO-eliminating slurry roll 8 is filled with CO-eliminating slurry for CO elimination. The anti-impact mechanism 7 includes a front end support plate 17, an end end support plate 21, and an elastic component 18. The front end support plate 17 and the end end support plate 21 are distributed at intervals, and their edges are respectively provided with a wire-passing hole 25 and a wire-passing hole 28. The front end support plate 17 is located outside the wire-passing hole 25. The first part of the plate 21 has a plurality of hexagonal through holes 26 evenly distributed; the second part of the end support plate 21, excluding the wire through hole 28, has a plurality of hexagonal through holes 27 evenly distributed, and the diameter of the first hexagonal through hole 26 is larger than the diameter of the second hexagonal through hole 27; multiple elastic components 18 are evenly distributed between the first end support plate 17 and the end support plate 21, and their two ends are respectively connected to the first end support plate 17 and the end support plate 21. Under the elastic action of the multiple elastic components 18, the first end support plate 17 and the end support plate 21 abut against the ends of the CO elimination slurry roll 8 and the charging tube 6, respectively; as a preferred embodiment, the elastic component 18 is a spring;

[0087] The first charging tube 3 and the second charging tube 5 are distributed opposite to each other at the ends of the two fasteners 14, and the first end of the charging tube body 6 is inserted into the sleeve section 16 of the two fasteners 14 respectively.

[0088] Multiple blasting units 2 are sequentially and adjacently filled in the blasting section, and the second charge tube 5 in each blasting unit 2 is closer to the orifice than the first charge tube 3;

[0089] The upward check mechanism 20 is installed in the preset blasting hole 1 and is located at the outer end of the blasting section to prevent multiple blasting units 2 from moving towards the hole opening;

[0090] Multi-section columnar sealing mud 19 is sequentially filled into the sealing section.

[0091] In this invention, several shaped charge holes are provided on the shaped charge tube body, facilitating directional blasting operations. Multiple sections of explosive cartridges are assembled into the shaped charge tube body, and two anti-slip mechanisms are installed at both ends of the shaped charge tube body. These two anti-slip mechanisms form two limiting structures at the two open ends of the shaped charge tube body, thus preventing the explosive cartridges from detaching from either open end. The anti-slip mechanism consists of an inner rigid frame and an outer flexible layer, with the rigid frame being a ring-shaped hollow frame. This not only provides a limiting function but also allows the blast wire connected to the explosive cartridge to pass smoothly through. Simultaneously, it facilitates the impact force of the explosive detonation to be effectively applied to the charging tube through the anti-slip mechanism. The fastener consists of a reduced-diameter section in the middle and sleeve sections at both ends. This allows for the use of the two sleeve sections at both ends to secure the charging tube and the shaped charge tube, while the reduced-diameter section forms a limiting structure at the ends of the charging tube and the shaped charge tube. One end of the explosive charge tube is opened, and a CO-eliminating slurry roll and an anti-impact structure are inserted inside to form the charge tube. The open end of the charge tube is then inserted into a fastener, creating a CO-eliminating section along the side of the multi-section explosive roll. This ensures that the CO-eliminating slurry in the roll remains intact under the high temperature and pressure conditions generated by the explosive blast. The anti-impact mechanism consists of a front support plate, an end support plate, and multiple elastic components. This provides good buffering capacity, thus offering a certain degree of cushioning for the CO-eliminating slurry roll inside the charge tube during the explosion. This helps prevent the CO-eliminating slurry roll from being pushed away by the impact force at the initial stage of the explosion, and allows it to be torn apart instantly. Furthermore, the high temperature and pressure conditions generated by the explosion allow the CO-eliminating slurry to evaporate rapidly, ensuring timely and sufficient contact with the generated CO gas, achieving efficient CO elimination. By mounting two charge tubes opposite each other at the ends of the shaped charge tube using two fasteners, efficient CO elimination from both sides can be achieved while reducing the amount of CO eliminator used. This significantly improves the CO elimination effect while maintaining in-situ CO elimination capability. Furthermore, since the CO eliminating slurry absorbs a large amount of heat during evaporation, it can effectively reduce the temperature inside the borehole. In addition, the droplet-shaped CO eliminating slurry can help extinguish open flames inside the borehole and carry away some of the generated dust, thus achieving flame and smoke suppression. By installing upward check mechanisms at the ends of multiple blasting units, it is easy to position the multiple blasting units after loading, thereby preventing the blasting units from detaching from the borehole. Filling the sealing section with multiple sections of columnar sealing clay can improve the sealing performance of the sealing section, which is beneficial to improving the blasting effect of the explosive.

[0092] This invention proposes a deep-hole blasting charging structure based on CO-eliminating slurry rolls. Multiple blasting units, consisting of a first charging tube, a shaped charge tube, and a second charging tube, are formed within the explosive blasting section of the borehole. This allows for the formation of two CO-eliminating sections on both sides of the multiple explosive rolls within each blasting unit. Consequently, CO generated by each blasting unit can be effectively eliminated in stages during the blasting process, and the resulting flame and dust can be suppressed to a certain extent. This achieves a three-in-one effect of in-situ CO elimination, flame suppression, and smoke suppression within the borehole.

[0093] In order to facilitate the upward check mechanism to reach the in-hole positioning state by impact triggering, thereby conveniently realizing the check function for multi-section blasting units, the upward check mechanism 20 includes a support base 22, a guide column 23, a connecting ring 24, a second support rod 30, a first support rod 29 and a triggering assembly;

[0094] The support base 22 abuts against the columnar sealing mud 19; the lower end of the guide pillar 23 is vertically fixedly connected to the support base 22, and its upper end is used to abut against the blasting unit 1; the connecting ring 23 is fixedly fitted onto the outside of the middle section of the guide pillar 23; two second support rods 30 are distributed opposite to each other on both sides of the connecting ring 24, and their upper ends are respectively hinged to the opposite sides of the connecting ring 24; two first support rods 29 are correspondingly arranged above the two second support rods 30, and are distributed opposite to each other on both sides of the guide pillar 23, and their upper ends are respectively hinged to the upper sides of the guide pillar 23, and their lower ends are respectively hinged to the middle sections of the two second support rods 30;

[0095] The triggering assembly includes a trigger element 33, a first elastic element 31, and a second elastic element 32. The two trigger elements 33 are fixedly installed on both sides of the lower part of the guide pillar 23 and correspond to the two second support rods 30. The two first elastic elements 31 are correspondingly arranged above the two second support rods 30 and are distributed on both sides of the guide pillar 23. Their upper ends are connected to the two sides of the upper part of the guide pillar 23, and their lower ends are connected to the upper parts of the two second support rods 30. The two second elastic elements 32 are correspondingly arranged below the two second support rods 30 and are distributed on both sides of the guide pillar 23. Their upper ends are connected to the middle sections of the two second support rods 30, and their lower ends are connected to the two trigger elements 33. When subjected to external impact force, both trigger elements 33 will detach from the two second elastic elements 32.

[0096] The connecting ring is fixedly fitted onto the middle section of the guide post and hinged to the upper ends of the two second support rods on opposite sides, allowing both second support rods to have a certain swing amplitude. Two trigger elements are installed below the connecting ring, and two second elastic elements are connected to the middle sections of the two second support rods and the two trigger elements respectively, allowing the two second elastic elements to keep the two second support rods in a contracted state. The lower ends of the two first elastic elements are connected to the two second support rods, and the two second elastic elements are connected to the upper ends of the guide post. This allows the two first elastic elements to provide tension in the expansion direction for the two second support rods. Thus, when the two second elastic elements disengage, the two second support rods can quickly reach an expanded state, thereby achieving rapid positioning within the hole. The upper ends of the two first support rods are hinged to both sides of the upper end of the guide column, and the lower ends of the two first support rods are hinged to the two second support rods. The two first support rods, together with the two second elastic elements, can maintain the retracted state of the two second support rods, which is conducive to the smooth loading of the upward check mechanism. At the same time, when the two second elastic elements are disengaged, the two movable first support rods will not affect the expansion action of the two second support rods.

[0097] To facilitate detonation, a detonator 35 is arranged in the blasting unit 2 near the orifice. The detonator 35 is embedded in a section of explosive roll 10 in the shaped charge tube 9 near the orifice. The blast wire 36 connected to the detonator 35 extends towards the orifice and reaches the outside of the preset blasting hole 1 after passing through the anti-slip mechanism 11, the second charge tube 5, the outer side of the upward check mechanism 20 and the edge of the columnar sealing mud 19 in sequence.

[0098] As a preferred embodiment, both the first elastic element 31 and the second elastic element 32 are springs;

[0099] As a preferred embodiment, the number of CO elimination slurry rolls 8 in both the first charging tube 3 and the second charging tube 5 is 1 to 3.

[0100] To effectively reduce the amount of CO scavenger used, while improving the CO scavenging effect and efficiency, and also to give the formed CO scavenging slurry a certain dust reduction effect, the CO scavenging slurry in Volume 8 is composed of CO scavenger, binder, surfactant, and deionized water. Based on the total mass of the CO scavenging slurry, the mass concentration of the CO scavenger is 5-20%, and the CO scavenger is a transition metal oxide composed of one or more elements selected from iron, manganese, and cerium, with a particle size of 0.01-0.1 mm. The mass concentration of the binder is 7-28%, and the mass concentration of the surfactant is 0.0001%-0.04%.

[0101] As a preferred embodiment, the charge tube body 6 in the first charge tube 3 and the second charge tube 5 is integrally formed from flame-retardant material; the energy-concentrating tube body 9 is integrally formed from flame-retardant material; and the anti-impact structure 7 and the upward check mechanism 20 are both made of hard metal material with good corrosion resistance and pressure resistance.

[0102] As a preferred embodiment, the charge tube body 6 in the first charge tube 3 and the second charge tube 5 is 1 / 6 to 1 / 4 of the length of the shaped charge tube body 9.

[0103] like Figure 10 and Figure 11 As shown, the present invention also provides an integrated pushing device for completing a deep hole blasting charge structure. The integrated pushing device 36 includes a fixed platform 37, a rotating bracket 63, a support platform 38, a hydraulic cylinder 45, a hydraulic cylinder 46, a main transmission mechanism 47, a sliding platform 39, a push plate 54, a guide frame 55, a pushing rod 57, a limiting frame 56, and an auxiliary transmission mechanism 58.

[0104] The fixed platform 37 has two pairs of casters 40 installed at both ends of its bottom length direction, and its front top and rear bottom are respectively fixedly connected to a lower hinge seat 41 and a lower hinge seat 42.

[0105] The lower end of the rotating bracket 63 is hinged to the top of the rear end of the fixed platform 37;

[0106] The support platform 38 is located above the fixed platform 37, and its rear bottom is hinged to the upper end of the rotating bracket 63. The front bottom and rear bottom are respectively fixedly connected to the upper hinge seat 43 and the upper hinge seat 44. The rotating bracket 63 can ensure that the support platform 38 maintains overall stability during operation.

[0107] The upper surface of the support platform 38 has a recessed mounting platform in the center area along the length direction, and two slides extending along the length direction are provided opposite to each other on both sides of the mounting platform in the width direction.

[0108] The piston rod end of the hydraulic cylinder 45 is hinged to the upper hinge seat 43, and the end of its cylinder is hinged to the lower hinge seat 41; the piston rod end of the hydraulic cylinder 46 is hinged to the upper hinge seat 44, and the end of its cylinder is hinged to the lower hinge seat 42; thus, through the cooperation of the hydraulic cylinder 45 and the hydraulic cylinder 46, the pitch angle and height of the support platform 38 can be controlled, enabling the loading and sealing of explosive holes at any tilt angle.

[0109] The main drive mechanism 47 is installed in the mounting platform and includes a driven sprocket 49, a driving sprocket 48, a chain 50, a pneumatic motor 51, and an electromagnetic reversing valve 52. The driven sprocket 49 is rotatably mounted on the front end of the mounting platform via a front bracket. The driving sprocket 48 is rotatably mounted on the rear end of the mounting platform via a rear bracket. The chain 50 is wound around the driven sprocket 49 and the driving sprocket 48. The pneumatic motor 51 is fixedly mounted on one side outside the driving sprocket 48, and the drive shaft of the pneumatic motor 51 is connected to the driving sprocket 48. The rotating shafts at the center of 8 are coaxially connected; the electromagnetic reversing valve 52 is installed on the wind motor 51. The electromagnetic reversing valve 52 is a three-position five-way reversing valve. When it is in the left position, it controls the wind motor 51 to rotate forward. When it is in the middle position, it controls the wind motor 51 to stop. When it is in the right position, it controls the wind motor 51 to rotate in reverse. The A port and B port of the electromagnetic reversing valve 52 are connected to the A port and B port of the wind motor 51, respectively. Its R port and S port are connected to the outside atmosphere. Its P port is connected to the air outlet of the connecting pipe 53. The air inlet of the connecting pipe 53 is used to connect to a high-pressure air source.

[0110] As a preferred embodiment, the electromagnetic reversing valve 52 is a three-position five-way reversing valve. When it is energized and operating in the left position, the air passage between its P port and A port is connected, the air passage between its S port and B port is connected, and its R port is closed. When it is de-energized and operating in the middle position, its R port, P port, S port, A port, and B port are all closed. When it is energized and operating in the right position, the air passage between its R port and A port is connected, the air passage between its P port and B port is connected, and its S port is closed.

[0111] The sliding platform 39 is in the shape of an inverted U, which covers the outside of the main transmission mechanism 47, and its two ends of the opening are slidably mounted in two slides on the support platform 38. At the same time, the sliding platform 39 is connected to a section of the chain 50 below.

[0112] The push plate 54 is fixedly connected to the rear end of the upper surface of the sliding platform 39, and a connecting rod is connected to its front end;

[0113] The guide frame 55 is fixedly connected to the front of the upper surface of the support platform 38 and is distributed correspondingly to the push plate 54. At the same time, a guide hole is opened in its center.

[0114] The push rod 57 is slidably mounted in the guide hole in the guide frame 55, and its rear end extends above the sliding platform 39, and is fixedly connected to the connecting rod connected to the front end of the push plate 54 by threads.

[0115] A pair of limiting frames 56 are distributed opposite to each other on both sides of the push rod 57 and located in front of the guide frame 55, and are fixedly installed on the top of the support platform 38. A pair of clamping and positioning mechanisms 65 are connected opposite to each other on both sides of the push rod 57 on the pair of limiting frames 56. The clamping and positioning mechanism 65 consists of a telescopic hydraulic cylinder and an arc-shaped clamping plate fixedly connected to the end of the piston rod of the telescopic hydraulic cylinder. The pair of clamping and positioning mechanisms 65 are used to position and clamp or release the push rod 57 by telescopic movement.

[0116] The auxiliary transmission mechanism 58 includes a roller support 60, a roller 61, a guide pulley 64, and a wire rope 62; the lower end of the roller support 60 is fixedly connected to the upper part of the rear section of the support platform 38; the roller 61 is rotatably mounted on the upper end of the roller support 60; the guide pulley 64 is located above the push rod 57 and is rotatably mounted between a pair of limit frames 56; one end of the wire rope 62 is connected to the front section of the push rod 57, and the other end is wound around the guide pulley 64 and then connected to the roller 61.

[0117] In this invention, the upper and lower ends of the rotating bracket are hinged to the supporting platform and the fixed platform, respectively, allowing the supporting platform to have flexible movement space above the fixed platform. The front end of the supporting platform is connected to the front end of the fixed platform via hydraulic cylinder one, and the rear end of the supporting platform is connected to the rear of the fixed platform via hydraulic cylinder two. The telescopic cooperation of hydraulic cylinders one and two allows for convenient adjustment of the tilt angle of the supporting platform, thus accommodating blasting hole loading and sealing operations at different tilt angles. The sliding platform is positioned outside the main transmission mechanism and slides with the supporting platform via a slide rail, ensuring that the sliding process does not affect the operation of the main transmission mechanism. The sliding platform is connected to a section of a chain, allowing the movement of the chain to drive the sliding platform to move significantly along the length of the supporting platform. A push plate is connected to the sliding platform, and a guide frame with guide holes is connected to the front end of the supporting platform corresponding to the push plate. This facilitates the connection of a push rod using the guide frame and push plate, enabling the movement of the sliding platform to drive the telescopic movement of the push rod. A pair of limiting frames are installed on opposite sides of the push rod, and a pair of clamping and positioning mechanisms are connected to the opposite sides of the pair of limiting frames. This allows for easy clamping and positioning of the push rod using the clamping and positioning mechanisms, facilitating both the smooth cascading of new push rods and the step-by-step removal of multiple push rods. A guide pulley is connected between the pair of limiting frames, and the steel wire rope connected to the push rod passes around the guide pulley and connects to the roller located at the rear of the support platform. This allows the guide pulley to be used as a support point, enabling operators to manually pull the steel wire rope to drive the push rod in small-amplitude reciprocating impact operations. The device coaxially connects the pneumatic motor to the drive sprocket, and then uses a three-position, five-way electromagnetic reversing valve to connect the pneumatic motor and the connecting pipeline. This allows for easy connection between the connecting pipeline and the compressed air pipeline, facilitating the transport of filling material inside the blast hole using the on-site compressed air pipeline. This enables filling in deep-hole blasting operations at different inclination angles, making full use of the site environment, reducing the likelihood of electrical equipment use, effectively reducing the number of on-site construction personnel, lowering the risk of deep-hole blasting operations, and improving blasting efficiency. This device can efficiently achieve deep-hole filling operations, significantly reducing the labor load of operators and effectively saving manpower and material resources.

[0118] As a preferred embodiment, handles 59 are fixedly connected to both the front and rear sides of the push plate 54.

[0119] like Figure 12 and Figure 13 As shown, the present invention also provides a method for efficient CO removal in deep-hole blasting, employing an integrated pushing device 36, comprising the following steps:

[0120] Step 1: Construct pre-designed blasting holes 1 and prepare blasting units 2;

[0121] Complete the drilling of the pre-set blasting hole 16 at the predetermined blasting location;

[0122] First, the anti-impact structure 7 and the CO-eliminating slurry roll 8 are sequentially loaded into the explosive charge tube body 6, thus forming the first explosive charge tube 3 and the second explosive charge tube 5. Second, an anti-slip mechanism 11 is installed inside one end of the shaped charge tube body 9, and then multiple sections of explosive roll 10 are sequentially loaded from the other end. Then, another anti-slip mechanism 11 is installed inside the other end of the shaped charge tube body 9, forming the shaped charge tube 4. Next, the connecting sections 16 of the two fasteners 14 are fitted onto the outside of both ends of the shaped charge tube 4. Finally, the first... The open ends of the charging tube 3 and the second charging tube 5 are inserted into the sleeve section 16 of the two fasteners 14 respectively to form a blasting unit 2. Multiple blasting units 2 are made in sequence in the above manner. For one of the blasting units 2, a detonator 34 is buried in a section of explosive roll 10 at its end, and the blast wire 35 connected to the detonator 34 passes through the wire hole 25 and wire hole 28 in the anti-slip mechanism 11, fastener 14, anti-impact mechanism 7 and the end of the charging tube body 6 in sequence.

[0123] Step 2: Load the blasting unit 2 and the upward check mechanism 20;

[0124] S21: First, move the integrated pushing device 36 to below the preset blast hole 1, and connect the connecting pipe 53 to the compressed air pipe, and then fix the position of the integrated pushing device 36; then, according to the angle of the preset blast hole 1, control the hydraulic cylinder 1 45 and the hydraulic cylinder 2 46 to extend and retract until the pushing rod 57 is adjusted to an angle that is compatible with the preset blast hole 1.

[0125] S22: Install multiple blasting units 2 and upward check mechanism 20 into the preset blasting hole 1 in sequence, and place the blasting unit 2 with the buried detonator 34 on the side close to the hole opening, place the support seat 22 of the upward check mechanism 20 on the side close to the hole opening, and at the same time, lead the blast line 35 out of the hole opening.

[0126] S23: Control the solenoid reversing valve 52 to work in the left position, supply the compressed gas in the compressed air pipeline to port A of the pneumatic motor 51 through the solenoid reversing valve 52, drive the pneumatic motor 51 to rotate forward, and use the rotating drive sprocket 48 to drive the chain 50, sliding platform 39 and push plate 54 to move towards the front end of the support platform 38. At the same time, make the push rod 57 extend outward and penetrate into the preset blasting hole 1. Use the extended push rod 57 to push the upward check mechanism 20 and multiple blasting units 2 towards the bottom of the hole.

[0127] S24: When the sliding platform 39 moves to the maximum stroke position at the front end of the support platform 38, first control the solenoid reversing valve 52 to work in the middle position, and control a pair of clamping and positioning mechanisms 65 to extend to clamp and position the push rod 57. Then, the connecting rod on the push plate 54 is disengaged from the push rod 57. Then control the solenoid reversing valve 52 to work in the right position, and supply the compressed gas in the compressed air pipeline to the B port of the wind motor 51 through the solenoid reversing valve 52, driving the wind motor 51 to reverse. The rotating drive sprocket 48 drives the chain 50, the sliding platform 39 and the push plate 54 to move towards the rear end of the support platform 38. When the sliding platform 39 is reset, control the solenoid reversing valve 52 to work in the middle position again.

[0128] S25: A new push rod 57 is installed on the support platform 38, and the male connector at the front end of the newly installed push rod 57 and the female connector of the previous push rod 57 are connected by threads, and the female connector of the newly installed push rod 57 is connected by threads to the connecting rod on the push plate 54.

[0129] S26: Repeat S23 to S25 multiple times until the upward check mechanism 20 and multiple blasting units 2 are pushed to the predetermined depth position, and then keep the connection state of multiple push rods 57 unchanged.

[0130] Step 3: Use the upward check mechanism 20 to locate multiple blasting units 2;

[0131] S31: The steel wire rope 62 is pulled back and forth, and the guide pulley 64 is used as the fulcrum to make the front end of the push rod 57 reciprocate to hit the support seat 22 of the upward check mechanism 2. The impact force generated by the impact triggers the action of the two trigger elements 33, which releases the connection state of the two second elastic elements 32. Under the elastic pull of the two first elastic elements 31, the ends of the two second support rods 30 are radially pushed outward and clamped on the wall of the blast hole, thereby realizing the positioning of the upward check mechanism 20 in the hole, and using the positioned upward check mechanism 20 to prevent multiple blasting units 2 from sliding towards the hole opening.

[0132] Step 4: Perform hole sealing.

[0133] S41: Multi-section columnar sealing clay 19 was made using yellow clay and a small amount of binder;

[0134] S42: First, by controlling the action of the solenoid reversing valve 52, the sliding platform 39 is reset to the rear end of the support platform 38. Then, a pair of clamping and positioning mechanisms 65 are extended to clamp and position the push rod 57 in front of the end push rod 57. Then, the connection state of the end push rod 57 is released and it is removed.

[0135] S43: By controlling the action of the electromagnetic reversing valve 52, the sliding platform 39 is moved to the front end of the support platform 38, and then the connecting rod on the push plate 54 is connected to the clamped push rod 57.

[0136] S44: Repeat S42 and S43 multiple times until the number of remaining push rods 57 on the support platform 38 meets the sealing requirements of the columnar sealing mud 19.

[0137] S45: By controlling the action of the electromagnetic reversing valve 52, the front end of the push rod 57 is moved out of the preset blast hole 1;

[0138] S46: First, install the multi-section columnar sealing mud 19 into the preset blasting hole 1 in sequence. Then, control the solenoid reversing valve 52 to work in the left position, so that the push rod 57 extends towards the bottom of the hole. Use the extended push rod 57 to push the multi-section columnar sealing mud 19 to the predetermined depth position. Then, control the solenoid reversing valve 52 to work in the middle position to maintain the pushing state of the push rod 57.

[0139] S47: The steel wire rope 62 is pulled back and forth, and the guide pulley 64 is used as a fulcrum to make the front end of the push rod 57 reciprocate to hit the outer end of the columnar sealing mud 19 until the columnar sealing mud 19 is compacted, thus completing the sealing operation of the blast hole.

[0140] Step 5: CO removal operations during the blasting process;

[0141] S51: After completing the filling operation of all the pre-set blasting holes 1, connect all the lead-out blasting wires 36 to form a blasting network. Then, evacuate the personnel to the outside of the safe area, and use the blasting wires 36 to detonate the detonator 90, and detonate the explosive roll 10 by detonating the detonator 35.

[0142] S52: The high temperature and pressure generated by the explosion of the explosive are applied to the CO elimination slurry roll 8 in the blasting unit 2, causing the CO elimination slurry to evaporate and come into full contact with the CO toxic gas to achieve CO elimination. At the same time, the evaporated CO elimination slurry absorbs the high temperature in the explosion space. Furthermore, some of the CO elimination slurry droplets are used to carry away some dust and eliminate open flames, thus achieving CO elimination and dust reduction.

[0143] In this invention, multiple blasting units are assembled within the blasting section inside the pre-fabricated blasting hole, with each unit arranged in a first charge tube-shaped charge tube-second charge tube configuration. This unique deep-hole blasting charging structure allows for the simultaneous elimination of CO gas and dust generated during the blasting process. Furthermore, the segmented elimination of CO and dust generated within each blasting unit significantly improves elimination efficiency and effectiveness. An upward check mechanism is installed at the end of each blasting unit to limit their movement, preventing them from detaching from the borehole during loading. Utilizing an integrated pushing device for deep-hole loading of multiple blasting units, upward check mechanisms, and multi-section columnar sealing mud significantly reduces the workload of operators, effectively saves manpower and resources, significantly improves loading efficiency, and effectively ensures loading quality.

[0144] This method is simple to implement and can eliminate the toxic and harmful CO gas generated by deep hole blasting operations at the source. At the same time, it can effectively reduce the construction difficulty and labor load of deep hole blasting workers, improve work efficiency, and effectively ensure the safety of workers' lives and health.
