Description

Technical Field

[0001] This invention relates to the field of mining technology, and in particular to a novel cutting and grooving equipment and method for underground mining. Background Technology

[0002] In underground mining engineering, cutting and slotting is a crucial preliminary process before blasting. The main purpose of cutting and slotting is to create sufficient free faces for blasting and compensation space for rock fragmentation during subsequent large-scale mining blasting. The quality of its construction and the effectiveness of the slotting directly affect the recovery rate, bulk density, and the continuity and safety of production operations throughout the mining area. With the development of modern mining technology and the continuous improvement of mine safety standards, more stringent requirements have been placed on the cutting and slotting process in deep-well environments in terms of safety, construction efficiency, and economy.

[0003] Currently, most mines employ the traditional "cut-shaft-parallel blast hole combined slotting" technique when carrying out slotting operations. This method primarily utilizes a pre-dug cut-shaft as compensation space for subsequent blasting, combined with parallel blast holes for backfilling and slotting. In actual construction, the cut-shaft typically requires conventional reverse excavation, i.e., manual excavation from bottom to top. During operation, workers must repeatedly erect and dismantle workbenches and safety sheds within the narrow shaft every few advance cycles, and perform heavy equipment handling, pipeline extension, and ladder and rock assembly work to gradually complete the shaft excavation and provide a foundation for parallel blast hole blasting.

[0004] However, years of mining practice have proven that the combined slotting process using the traditional conventional method of reverse-excavation of the riser has many serious defects and technical difficulties: It poses significant safety hazards, requiring workers to frequently climb ladders and work in mid-air, and the confined space underground suffers from extremely poor ventilation and lighting, making it highly susceptible to serious accidents such as riser fumes poisoning and personnel falls; the process is labor-intensive and extremely slow, with tedious auxiliary operations such as setting up and dismantling workbenches taking up a lot of time, resulting in low blasting efficiency and failing to meet the demands of rapid mining in modern mines; this method requires a large amount of timber and other materials to construct safety protection facilities, and relying solely on the riser as compensation space often leads to poor blasting pressure, resulting in a lengthy construction period and extremely high material and labor costs. Therefore, this application proposes a novel cutting and slotting equipment and method for underground mining. Summary of the Invention

[0005] The purpose of this invention is to address the problems in the background technology, such as the high safety risks and low construction efficiency of traditional conventional reverse excavation cutting risers, the easy stress and vibration of the drill bit during deep hole drilling, and the leakage of blasting energy due to discontinuous and poorly compacted manual filling of the blasting mud. The invention proposes a new type of cutting and slotting equipment and method for underground mining.

[0006] In a first aspect, this application provides a novel cutting and grooving device for underground mining methods, comprising a trolley, an adaptive anti-deviation component, a rotary cutting mud filling component, and a power head component.

The adaptive anti-deviation component includes a fixed base and a linkage top plate. The fixed base is fixedly connected to the top side of the hydraulic propulsion beam rock drill, and a drill bit is disposed on the top side of the hydraulic propulsion beam rock drill, penetrating the center of the adaptive anti-deviation component. The power head component includes a multi-directional adjustment base and a support plate. The multi-directional adjustment base is fixedly connected to the front end of the hydraulic propulsion beam rock drill, and the support plate is fixedly connected to the front end of the multi-directional adjustment base. The rotary cutting mud filling component includes a shell. Multiple corner posts are fixedly connected to the top side of the support plate, and the top ends of the corner posts are fixedly connected to the bottom side of the shell. A turntable is rotatably connected inside the shell, and a motor is fixedly connected to the bottom side of the shell. The drive end of the motor is fixedly connected to the bottom side of the turntable.

[0007] Optionally, the fixed base has multiple buffer grooves distributed circumferentially on its inner side. Each buffer groove has a buffer rod slidably connected inside it. The top side of the buffer rod is fixedly connected to the bottom side of the linkage top plate. A buffer spring is sleeved on the outside of the buffer rod. The top of the buffer spring abuts against the bottom side of the linkage top plate. Multiple inner cylinders are hinged to the inner side of the fixed base. An outer sleeve is slidably connected to the outside of each inner cylinder. Each outer sleeve has a guide groove on its outer side.

[0008] Optionally, the adaptive anti-skew assembly further includes an inner pressure rod and a telescopic spring. The inner pressure rod is fixedly connected inside the inner cylinder. The inner side of the inner pressure rod abuts against one end of the telescopic spring, and the other end of the telescopic spring abuts against the bottom end of the inner wall of the inner cylinder.

[0009] Optionally, a hinged ball head is fixedly connected to the outer side of the outer sleeve, and a support pad is rotatably connected to the outer side of the hinged ball head. Multiple connecting rods distributed circumferentially are hinged to the outer side of the linkage top plate, and the bottom end of the connecting rod passes through the guide groove and is hinged to the inner pressure rod.

[0010] Optionally, the rotary clay filling assembly further includes a storage box, which is fixedly connected to the upper part of the housing, with the rotary table located below the storage box. The storage box has a storage cavity and a filling cavity inside.

[0011] Optionally, a cover is installed on the top side of the housing, a cover is threadedly connected to the inside of the storage cavity, a compression spring is fixedly connected to the bottom side of the cover, the compression spring is disposed inside the storage cavity, and multiple evenly distributed feeding cavities are opened on the inside of the turntable.

[0012] Optionally, a plurality of guide rods are fixedly connected between the support plate and the bottom side of the housing. A slider is slidably connected to the outside of the guide rod. A mud vibrating tamping machine is fixedly connected between the sliders. A piston push rod is fixedly connected to the top side of the mud vibrating tamping machine. The top end of the piston push rod passes through the bottom side of the housing and is slidably connected inside the filling cavity.

[0013] Optionally, the power head assembly further includes a hydraulic drive motor, which is fixedly connected to the bottom side of the support plate and the drive end of the hydraulic drive motor is fixedly connected to the slider.

[0014] Secondly, this application provides a novel cutting and grooving method for underground mining, applied to the equipment described in the first aspect, the grooving method comprising the following steps: Contour measurement and preparation: Conduct actual measurements of the contour of the cutting approach and the measure roadway to ensure that the length of the measure roadway for the cutting approach construction is not less than 5m, so as to provide compensation space and free surface for subsequent top blasting. Hole layout design and equipment positioning: Determine the minimum angle of the first row of holes based on the measured height of the top plate along the grooving path. Design 7 rows of parallel medium-deep holes arranged in a fan shape along the grooving path. Set three blast holes in each row. Set the bottom distance of the holes between adjacent rows to 2 to 3 m. The distance between the blast holes in the same row should not be greater than 1.5 m. Then, move the trolley to the grooving area. Medium-deep hole drilling: By adjusting the positioning drill arm, the hydraulic propulsion beam rock drill is tilted upward along the cutting path. The drill bit is started to carry out medium-deep hole construction. During the drilling process, the adaptive anti-deviation component is used to keep the drilling trajectory close to the rock wall. The construction depth of each row of medium-deep holes is controlled to be no less than the design depth, and the depth exceeding the design depth shall not exceed 0.5m. Filling and tamping of the borehole: After the construction of a single row of medium-deep holes is completed, start the rotary drum filling assembly and the power head assembly. Push the loaded borehole into the medium-deep hole through the piston push rod, and use the borehole vibration tamping machine to drive the piston push rod to tamp the borehole at high frequency. Control the effective filling length of the borehole to be no less than 1.5m. Grooving by blasting row by row: After all the medium and deep holes have been constructed and the stemming has been filled, the top blasting is carried out row by row in a bottom-up order. After the blasting is completed, a groove is formed that meets the conditions for grooving construction.

[0015] Compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. In this invention, with the rigid circumferential constraint of the adaptive anti-deviation component with a multi-point annular energy-absorbing and shock-absorbing frame and a universal degree-of-freedom support pad, the drill bit maintains a straight and stable linear trajectory when facing complex and harsh hard rock conditions downhole and rotating and drilling at high speed. This solves the problem that traditional equipment is prone to strong reverse vibration when it comes into contact with irregular rock surfaces during drilling, which can lead to the drill bit jumping or shifting.

[0016] 2. In this invention, the precise circumferential torque output by the motor drive end drives the turntable inside the housing to rotate flexibly in a stepping motion, thereby realizing the rapid overlap and switching of multiple peripherally distributed feeding chambers and the upper filling chamber in the axial direction, which greatly shortens the internal turnover route of the material and achieves the effect of in-situ fully automatic uninterrupted continuous feeding of thick gun clay.

[0019] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0020] like Figure 1 and Figure 2 As shown, this invention proposes a novel cutting and grooving device for underground mining, comprising a trolley 1, an adaptive anti-deviation component 4, a rotary cutting mud filling component 5, and a power head component 8. A positioning drill arm 2 is mounted at the front end of the trolley 1, and a hydraulic propulsion beam rock drill 3 is mounted at the front end of the positioning drill arm 2. Through the compact spatial arrangement of these core components, large-scale and highly stable autonomous tunneling and drilling operations can be achieved in underground mines. The trolley 1 serves as the mobile support base for the entire equipment, enabling all subsequent operating mechanisms to move flexibly and position precisely in rugged mine tunnels.

[0021] like Figures 3-5 As shown, the adaptive anti-deviation component 4 includes a fixed base 4013 and a linkage top plate 4012. The fixed base 4013 is fixedly connected to the top side of the hydraulic propulsion beam rock drill 3. The drill bit 6 is installed on the top side of the hydraulic propulsion beam rock drill 3 and passes through the center of the adaptive anti-deviation component 4. This coaxial through-space structure can maximize the space utilization within the limited working cross-section of the front end of the robotic arm, and facilitates the adaptive anti-deviation component 4 to provide immediate rigid circumferential constraint on the high-speed rotating drill bit 6, preventing the drill bit 6 from jumping or veering when it contacts hard rock.

[0022] The fixed base 4013 has multiple circumferentially distributed buffer grooves 4011 on its inner side. Each buffer groove 4011 has a buffer rod 405 slidably connected inside. The top of the buffer rod 405 is fixedly connected to the bottom of the linkage top plate 4012. A buffer spring 406 is sleeved on the outside of the buffer rod 405, with its top abutting against the bottom of the linkage top plate 4012. Multiple inner cylinders 403 are hinged to the inner side of the fixed base 4013. An outer sleeve 402 is slidably connected to the outer side of each inner cylinder 403, and a guide groove 404 is provided on the outer side of each outer sleeve 402. This multi-point encircling annular energy-absorbing frame can disperse and absorb asymmetrical and severe impact forces from the top in all directions. When the linkage top plate 4012 is compressed, the buffer rod 405 will penetrate deeper into the buffer groove 4011, forcing the buffer spring 406 to undergo elastic deformation to flexibly dissipate the reverse vibration caused by the hard impact with the rock wall. Simultaneously, the outer sleeve 402 and the inner cylinders 403 provide stable guiding sliding profiles externally.

[0023] In this embodiment, the adaptive anti-skew component 4 further includes an inner pressure rod 408 and a telescopic spring 4010. The inner pressure rod 408 is fixedly connected inside the inner cylinder 403. The inner side of the inner pressure rod 408 abuts against one end of the telescopic spring 4010, and the other end of the telescopic spring 4010 abuts against the bottom end of the inner wall of the inner cylinder 403. This double-layer sleeve nesting structure with built-in elastic element greatly and effectively protects the core transmission component and gives it strong axial deformation compensation characteristics. The continuous reset and outward pushing force provided by the telescopic spring 4010 can ensure that the inner pressure rod 408 always has a dynamic tendency to actively push outward in the inner cylinder 403.

[0024] The outer sleeve 402 is fixedly connected to a hinged ball head 409, and a support pad 401 is rotatably connected to the outer side of the hinged ball head 409. Multiple connecting rods 407 distributed circumferentially are hinged to the outer side of the linkage top plate 4012. The bottom end of each connecting rod 407 passes through a guide groove 404 and is hinged to an inner pressure rod 408. Utilizing the unique omnidirectional rotational freedom of the hinged ball head 409, the support pad 401 can be driven to form a completely adhered and close contact with the irregular, uneven rock wall downhole. When the multiple connecting rods 407 pull the inner pressure rod 408 back and forth along the direction of the guide groove 404, this spatial linkage network instantly causes the support pad 401 to firmly press against the surrounding rock.

[0025] like Figure 6 As shown, the power head assembly 8 includes a multi-directional adjustment base 806 and a support plate 801. The multi-directional adjustment base 806 is fixedly connected to the front end of the hydraulic propulsion beam rock drill 3, and the support plate 801 is fixedly connected to the front end of the multi-directional adjustment base 806. This stepped, multi-level load-bearing design not only significantly enhances the mechanical structural rigidity of the front cantilever mechanism, but also greatly facilitates the flexible fine-tuning of subsequent construction angles according to the complex geological conditions underground. The spatial three-dimensional posture of the support plate 801 can be adjusted at any time through the multi-directional adjustment base 806.

[0026] Multiple guide rods 804 are fixedly connected between the support plate 801 and the bottom side of the housing 501. Slider blocks 803 are slidably connected to the outside of the guide rods 804. A clay vibrating tamping machine 805 is fixedly connected between the sliders 803. A piston push rod 9 is fixedly connected to the top side of the clay vibrating tamping machine 805. The top of the piston push rod 9 penetrates the bottom side of the housing 501 and is slidably connected inside the filling cavity 506. The high-strength linear guide pair provides an absolutely straight running trajectory constraint for the high-frequency reciprocating impact action. The slider 803 slides smoothly along the guide rods 804, which not only ensures that the clay vibrating tamping machine 805 can exert force steadily forward, but also ensures that the piston push rod 9 will not get stuck due to force when pushing the clay into the filling cavity 506, thus improving the accuracy of the action. During the specific feeding process, the piston push rod 9 will be precisely pushed upward under the directional linear drive of the slider 803, smoothly passing through the inside of the turntable 503, thereby sending the corresponding material out in a straight line.

[0027] In this embodiment, the power head assembly 8 also includes a hydraulic drive motor 807, which is fixedly connected to the bottom side of the support plate 801, and the drive end of the hydraulic drive motor 807 is fixedly connected to the slider 803. The high-torque, heavy-duty hydraulic power source can provide abundant mechanical energy for the jacking operation under harsh working conditions. The hydraulic drive motor 807 directly applies a huge thrust or pull force to the slider 803 through its drive end, thereby guiding all connected functional components below to complete an automated, high-load mechanical conveying cycle.

[0028] like Figures 6-7 As shown, the rotary drum filling assembly 5 includes a housing 501, a support plate 801 with multiple corner posts 802 fixedly connected to the top side, the tops of the corner posts 802 fixedly connected to the bottom side of the housing 501, a turntable 503 rotatably connected inside the housing 501, and a motor 7 fixedly connected to the bottom side of the housing 501. The drive end of the motor 7 is fixedly connected to the bottom side of the turntable 503. This three-dimensional frame structure can achieve autonomous and stable material transfer from above while preserving the bottom power space. When the motor 7 starts, its drive end directly provides the turntable 503 with precise circumferential torque, allowing it to rotate smoothly inside the housing 501 for continuous feeding. When the piston rod 9 pushes forward and sends the clay in the current feeding chamber 504 straight from the filling chamber 506 into the final hole, as the piston rod 9 returns and disengages, the motor 7 drives the turntable 503 to rotate to automatically switch between different feeding chambers 504 and filling chambers 506. This, in conjunction with the slider 803 driving the piston rod 9 to replenish the clay in multiple strokes, achieves continuous operation.

[0029] In this embodiment, the rotary taphole clay filling assembly 5 also includes a storage box 502, which is fixedly connected to the upper part of the housing 501. The rotary plate 503 is located below the storage box 502, and the storage box 502 has a storage cavity 507 and a filling cavity 506 inside. This gravity-fed functional partition with upper storage and lower rotation greatly shortens the turnover path of the sealing material inside the machine body. The storage box 502 can properly store unused taphole clay in the storage cavity 507, and can also accurately guide and gather the target material in the filling cavity 506 in the early stage to prevent material spillage.

[0030] The housing 501 has a cover 508 installed on its top side, and the storage cavity 507 has a cover 508 threadedly connected to its inner side. A compression spring 505 is fixedly connected to the bottom side of the cover 508. The compression spring 505 is located inside the storage cavity 507, and the turntable 503 has multiple evenly distributed feeding chambers 504 on its inner side. The threaded cover 508 can tightly engage with the housing 501, effectively isolating the well from dust and mud contamination. The compression spring 505, located inside the storage cavity 507, forces the highly viscous drilling mud to be squeezed and filled into each feeding chamber 504 of the turntable 503 below through a constant downward pressure, effectively preventing the phenomenon of suspended material jamming. Based on this sealed self-pressurized environment, when the turntable 503 rotates, once the empty feeding chamber 504 is moved and precisely aligned with the storage chamber 507 above, the subsequent slurry in the storage chamber 507 will automatically fall and fill under the active pushing of the compression spring 505, thereby achieving in-situ automated material replenishment through the continuous rotation and repositioning of the turntable 503.

[0031] like Figures 1-9 As shown, a novel cutting and slotting method in underground mining includes the following steps: Contour Measurement and Preparation: Conduct on-site measurements of the contours of the cutting approach and the auxiliary roadway to ensure that the length of the auxiliary roadway for the cutting approach construction is not less than 5m, so as to provide compensation space and free face for subsequent roof blasting. Before on-site construction operations in the mine, this step is the core technical prerequisite to prevent large-scale blind blasting, blind cracks, or rock jamming in subsequent blasting operations. Accurate contour data can not only accurately assess the integrity of the current surrounding rock mass, but also provide a perfect buffer and stress release channel for rock fragmentation after subsequent blasting with the help of the reserved free space of not less than 5m. Hole layout design and equipment positioning: Based on the measured height of the top plate along the grooving path, determine the minimum angle of the first row of boreholes. Design 7 rows of parallel medium-deep holes arranged in a fan shape along the grooving path, with three blast holes in each row. Set the bottom distance between adjacent rows of holes to 2 to 3 meters, and the distance between parallel blast holes in the same row should not exceed 1.5 meters. Then, move and position the trolley 1 to the grooving area. This regular intersecting fan-shaped grid pattern of holes can ensure that the energy generated by the explosive detonation is released in the most gentle and uniform way, greatly reducing the retention of dead corners of collapse. And firmly rooting the trolley 1 in the grooving construction area is to build an unshakable rigid base for the subsequent series of high-vibration and high-load drilling operations, and prevent the overall equipment from tipping over or shifting. Medium-deep hole drilling: By adjusting the positioning drill arm 2, the hydraulic propulsion beam rock drill 3 is tilted upward along the cutting path, and the drill bit 6 is started to carry out medium-deep hole construction. During the drilling process, the adaptive anti-deviation component 4 is used to keep the drilling trajectory close to the rock wall, and the construction depth of each row of medium-deep holes is controlled to be no less than the design depth, and the depth exceeding the design depth shall not exceed 0.5m. This ingenious dynamic coordination of the large swing angle of the robotic arm and the lateral adaptive straightening is the core secret to drilling ultra-long and ultra-straight blast holes. When the positioning drill arm 2 lifts the hydraulic propulsion beam rock drill 3 high, the adaptive anti-deviation component 4 will automatically lock and stick to the rough rock wall, establish a stable trajectory guide for the drill bit 6 that is rapidly drilling the rock, and prevent any unnecessary over-drilling or under-drilling at the bottom of the hole. Filling and tamping of the borehole: After the construction of a single row of medium-deep holes is completed, the rotary drum filling assembly 5 and the power head assembly 8 are started. The feed drum mud is pushed into the medium-deep hole by the piston pusher 9, and the drum mud tamping machine 805 drives the piston pusher 9 to tamp the drum mud at high frequency. The effective filling length of the drum mud is controlled to be no less than 1.5m. The dense, seamless and high-strength drum mud sealing is the key to effectively locking the explosive gas, preventing premature leakage of detonation energy and improving the efficiency of blasting. Through the automatic feeding of the rotary drum filling assembly 5 and the power head assembly 8, the piston pusher 9 vibrates at high speed like a tamping rod under the vibration of the drum mud tamping machine 805, compacting the drum mud of more than 1.5m layer by layer, eliminating cavities and air bubbles in the middle.

[0032] Pit formation by sequential blasting: After all medium-deep holes have been drilled and the stemming material has been filled, blasting is carried out sequentially from bottom to top, creating a cut that meets the requirements for slotting. Strictly following the bottom-up, stepped blasting rhythm perfectly creates an excellent free face for each subsequent row of blast holes, thereby comprehensively reducing the inherent strong confinement of the rock. This gradual caving mechanism not only minimizes the shock wave impact on the surrounding permanent rock, but also cuts out a standardized slot cavity in one go, clearing all obstacles for subsequent large-scale, high-efficiency mining operations.

[0033] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

A novel cutting and grooving device for underground mining according to claim 7, characterized in that, The power head assembly (8) also includes a hydraulic drive (807), which is fixedly connected to the bottom side of the support plate (801) and the driving end of the hydraulic drive (807) is fixedly connected to the slider (803).

9. A novel cutting and slotting method in underground mining, applied to the equipment described in any one of claims 1-8, characterized in that: The grooving method includes the following steps: Contour measurement and preparation: Conduct actual measurements of the contour of the cutting approach and the measure roadway to ensure that the length of the measure roadway for the cutting approach construction is not less than 5m, so as to provide compensation space and free surface for subsequent top blasting. Hole layout design and equipment positioning: Determine the minimum angle of the first row of drill holes based on the measured height of the top plate of the grooving path. Design 7 rows of parallel medium-deep holes arranged in a fan shape along the grooving path. Set three blast holes in each row. Set the bottom distance between adjacent rows of holes to 2 to 3 m. The distance between blast holes distributed in parallel in the same row shall not be greater than 1.5 m. Then, drive the trolley (1) to the grooving area. Medium-deep hole drilling construction: By adjusting the positioning drill arm (2), the hydraulic propulsion beam rock drill (3) is tilted upward along the cutting path. The drill bit (6) is started to carry out medium-deep hole construction. During the drilling process, the adaptive anti-deviation component (4) is used to adhere to the rock wall to maintain the drilling trajectory. The construction depth of each row of medium-deep holes is controlled to be no less than the design depth, and the depth exceeding the design depth shall not exceed 0.5m. Filling and tamping of the borehole: After the construction of the single-row medium-deep hole is completed, start the rotary drum filling assembly (5) and the power head assembly (8), push the loaded borehole into the medium-deep hole through the piston push rod (9), and use the borehole vibration tamping machine (805) to drive the piston push rod (9) to tamp the borehole at high frequency, and control the effective filling length of the borehole to be no less than 1.5m; Grooving by blasting row by row: After all the medium and deep holes have been constructed and the stemming has been filled, the top blasting is carried out row by row in a bottom-up order. After the blasting is completed, a groove is formed that meets the conditions for grooving construction.
