Description

Technical Field

[0001] This invention relates to the field of blasting technology, specifically to a combined method for deep-hole rock drilling and blasting in mining. Background Technology

[0002] Blasting is a technique that utilizes the compression, loosening, destruction, throwing, and destructive effects produced by the explosion of explosives in air, water, soil, rock, or other materials to achieve a desired objective. When an explosive charge or package detonates in soil, rock, or a structure, it causes compression, deformation, destruction, loosening, and throwing of the material. Blasting is primarily used in earthwork engineering and the demolition of metal buildings and structures. Blasting is applied in various fields, requiring the use of blasting devices and methods.

[0003] Chinese patent (CN113847033A) discloses a blasting structure for a deep-hole drilling blasting method in mining, relating to the field of underground mining technology. In a segmented planar mining approach, deep holes are drilled using pneumatic or hydraulic drilling equipment, followed by explosive blasting. The deep holes are arranged in a fan-shaped or parallel pattern, with two or more different diameters arranged alternately or in a bundle. Explosive blasting is performed according to the different arrangements, with larger diameter holes detonated first, followed by smaller diameter holes. Smaller diameter holes have higher drilling efficiency, require less explosive charge, and produce fewer harmful gases, reducing drilling and blasting costs without affecting the blasting effect, thus improving mining efficiency and reducing mining costs. Different diameter holes are detonated using different types of detonators, with larger diameter holes acting as the main blaster and smaller diameter holes acting as auxiliary blasters, which helps reduce blast shock waves and seismic waves. Current blasting methods typically utilize explosives as blasting structures. While effective blasting is achieved, the large number of explosives required necessitates the simultaneous introduction of multiple sets. The inability to quickly assemble and combine these explosives leads to significant waste of space within the blasting area, hindering optimal explosive placement and impacting blasting efficiency. Furthermore, the blasting structure itself cannot be quickly positioned within the blasting area, requiring numerous positioning components and structures, which greatly increases explosive installation time and overall blasting efficiency. To address these issues, a combined deep-hole drilling blasting method for mining is urgently needed. Summary of the Invention

[0004] The purpose of this invention is to address the problems in current blasting methods, where the blasting structure typically consists of explosives. While effective blasting can be achieved, the large number of explosives required necessitates the simultaneous introduction of multiple sets, which cannot be quickly assembled and combined. This results in significant waste of space within the blasting area, hindering optimal explosive placement and impacting blasting efficiency. Furthermore, the blasting structure itself cannot be quickly positioned within the blasting area, requiring numerous positioning components and structures, which greatly affects explosive installation time and overall blasting efficiency. Therefore, this invention proposes a combined deep-hole drilling blasting method for mining.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A combined deep-hole drilling and blasting method for mining, which employs a combined deep-hole drilling and blasting device for mining.

[0007] The combined deep-hole rock drilling and blasting device for mining includes a side mounting shell and a detonator connection assembly. The top of the side mounting shell is provided with an inner mounting hole, and a quick positioning assembly is provided inside the side mounting shell. A blasting detonator controller is fixedly installed at the front end of the side mounting shell, and a bottom slide rail is fixedly installed on the bottom surface of the side mounting shell. A blasting detonator is fixedly installed at the front end of the blasting detonator controller.

[0008] The quick positioning assembly includes an inner mounting plate, a longitudinal slide rod, a pressure spring, a pressure shaft, side locking pins, and a side top spring. The bottom end of the longitudinal slide rod is fixedly installed at the bottom of the inner cavity of the side mounting housing. The pressure shaft has a sliding hole along its axial direction. The pressure spring is sleeved on the lower part of the longitudinal slide rod, and the pressure shaft is sleeved on the upper part of the longitudinal slide rod through the sliding hole. The bottom end of the pressure spring presses against the bottom of the inner cavity of the side mounting housing, and the top end of the pressure spring contacts the bottom end of the pressure shaft. The pressure shaft is fixedly installed on both its left and right sides. The device has a side retainer. The top end of the pressure bearing shaft extends upward into the mounting inner hole and slides into the mounting inner hole. The top of the inner cavity of the side mounting shell is fixedly provided with mounting inner plates near the left and right sides respectively. The left and right sides of the side mounting shell are provided with side sliding holes near the top respectively. Side retaining pins are slidably installed in both side sliding holes. The side retaining pins are provided with limiting holes. The top of the side retainer is inserted into the limiting hole on the corresponding side retaining pin. Side top springs are provided between the side retaining pins on the left and right sides and the mounting inner plates on the corresponding sides respectively.

[0009] The detonator connection assembly includes a bottom slider, a side positioning plate, a torsion spring, a built-in spring, and a positioning pin. The top surface of the bottom slider has a mounting plate groove and a mounting slide groove, with the mounting slide groove located outside the mounting plate groove. The side positioning plate is rotatably mounted within the mounting plate groove via a hinge. Side mounting shafts are fixedly mounted on both the front and rear sides of the side positioning plate. The outer ends of the side mounting shafts are rotatably connected to rotating holes on the inner wall of the mounting plate groove. The torsion spring is sleeved around the side mounting shafts, with one end fixed to the side mounting shaft and the other end fixedly connected to the groove wall of the corresponding side mounting plate groove. The bottom slider has an inner hole, within which the built-in spring and positioning pin are placed. One end of the built-in spring presses against the bottom of the inner hole, and the bottom end of the positioning pin presses against the top end of the built-in spring. The positioning pin slides within the inner hole of the bottom slider, with the top end extending out of the inner hole. The mounting slide groove slides within the bottom slide rail. A side pull ring is fixedly mounted on one outer wall of the bottom slider.

[0010] The outer side of the blasting detonator controller is provided with threads near the front side. An adjustment signal shield is installed on the outer side of the blasting detonator controller through threaded engagement. A bottom pull ring is fixedly installed on the bottom front surface of the adjustment signal shield.

[0011] The deep-hole drilling and blasting method in this combined mining process includes the following steps:

[0012] S1. First, acquire various types of information about the blasting area, and then analyze the acquired information. The acquired information mainly includes: the geographical location of the blasting area, the geological information of the blasting area, the information of the facilities around the blasting area, and the area information of the blasting area.

[0013] S2. Based on the obtained information, calculate the appropriate blasting depth and conduct data simulation tests on the data;

[0014] S3. The blasting process is further divided into four to six stages, with each stage using a different number of blasting detonators.

[0015] S4. Based on the divided stages, plan the number of blasting detonators to be used in each stage. The number of blasting detonators in each stage is 6-10.

[0016] S5. According to the planned data, first assemble the detonators by combining them in pairs. When assembling, the side mounting shells of the two detonators are pressed tightly together. The bottom slide rails of the two pressed side mounting shells are placed in the mounting groove of the bottom slider and slide in cooperation with the mounting groove. The bottom surfaces of the two pressed side mounting shells are tightly fitted with the top surface of the side positioning plate. At this time, pull the side pull ring of the detonator connecting component to pull the bottom slider to slide until the bottom slider slides until the side positioning plate is no longer in contact with the bottom surfaces of the two assembled detonator side mounting shells. At this time, the side positioning plate can be rotated outward through the side mounting axis under the action of the torsion spring until the side positioning plate is at a right angle. Then push the bottom slider back so that the side positioning plate is fitted with the side of one of the side mounting shells of the assembled detonator. During the movement of the bottom slider, the positioning pin will also directly engage with the bottom locking hole of the other side mounting shell of the assembled detonator, completing the combination of the two detonators.

[0017] S6. According to the stage division, carry the corresponding number of detonators and install them in the deep hole. During installation, the side mounting shell of the combined detonator can be directly inserted upward into the groove of the deep hole. At this time, the bearing shaft of the quick positioning component is squeezed and displaced downward. The bearing shaft can simultaneously drive the side clamp to move downward. At this time, the top of the side clamp will directly disengage from the bottom hole set on the bottom surface of the side clamp pin. At this time, the side clamp pin between the two side mounting shells of the assembled detonator will not be pushed out due to the obstruction of the shells. The side top springs on the outermost left and right sides of the two side mounting shells of the assembled detonator will lose their restraint and push out the side clamp pin and insert it into the deep hole groove, thus completing the quick installation of the detonator before blasting.

[0018] S7. After installation, rotate the signal shielding cover to move it forward on the detonator controller until the signal receiving position of the detonator controller is exposed and no longer shielded.

[0019] S8. Evacuate the site and control the blasting.

[0020] As a preferred embodiment of the present invention, a drill probe is fixedly installed at the front end of the blasting detonator.

[0021] As a preferred embodiment of the present invention, the bottom surface of the side mounting shell is provided with bottom slide rails near the front and rear sides respectively, and the top surface of the bottom slider is provided with mounting grooves near the front and rear sides respectively. The two bottom slide rails on the bottom surface of the side mounting shell correspond one-to-one with the mounting grooves on the top surface of the bottom slider and slide in a sliding fit.

[0022] Compared with the prior art, the present invention has the following technical effects:

[0023] 1. This invention includes a detonator connecting assembly. Before blasting, when assembling detonators, the side mounting shells of two detonators are pressed tightly together. At this time, the side pull ring of the detonator connecting assembly is pulled, thereby moving the bottom slider until the bottom slider moves to the point where the side locking positioning plate is no longer in contact with the side mounting shell of the assembled detonator. At this point, the side locking positioning plate can begin to rotate under the action of the torsion spring via the side mounting shaft until the side locking positioning plate is at a right angle. Then, the bottom slider is pushed back, so that the side locking positioning plate is in contact with the side of one of the side mounting shells of the assembled detonator. During the movement of the bottom slider, the positioning pin will also directly engage with the locking hole at the bottom of the other side mounting shell of the assembled detonator, completing the combination of the two detonators. Through this design, detonators can be quickly assembled according to requirements to ensure the subsequent use effect of the detonators. It effectively solves the problem that the explosives cannot be quickly assembled and combined, resulting in a large amount of wasted space in the blasting area and affecting the blasting effect.

[0024] 2. This invention features a quick-positioning component. After the detonator is assembled, when it needs to be installed into the blasting area, the assembled side mounting shell is directly inserted upwards into the deep hole groove. At this time, the pressure shaft of the quick-positioning component is squeezed and displaced downwards. The pressure shaft can simultaneously drive the side clamping parts downwards. At this time, the top of the side clamping parts will directly disengage from the bottom hole set on the bottom surface of the side clamping pin. At this time, the side clamping pins between the two assembled detonator side mounting shells will not be pushed out due to the obstruction of the shells. The side top springs on the outermost left and right sides of the two assembled detonator side mounting shells will lose their restraint and push out the side clamping pins and insert them into the deep hole groove, completing the quick installation of the detonator before blasting. Through this design, the quick assembly of the assembled detonator can be achieved without the use of additional tools and parts. It is particularly suitable for this kind of deep hole installation operation, greatly improving the application effect of the blasting detonator.

[0025] 3. This invention is equipped with an adjustable signal shield. When the detonator controller is not in use, the adjustable signal shield can block the signal receiving area of ​​the detonator, avoiding misoperation and greatly ensuring the safety of the detonator application. At the same time, the blasting method first collects and analyzes a lot of information in the blasting area, thus obtaining a lot of information to provide a theoretical basis for subsequent blasting. In addition, the use of multiple batches of blasting can greatly improve the blasting effect. The overall application effect of the method is good. Attached Figure Description

The pressure bearing shaft 54 ​​is sleeved on the upper part of the longitudinal slide rod 57 through the sliding hole. The bottom end of the pressure bearing spring 55 presses against the bottom of the inner cavity of the side mounting housing 4. The top end of the pressure bearing spring 55 contacts the bottom end of the pressure bearing shaft 54. Side clamps 56 are fixedly installed on both the left and right sides of the pressure bearing shaft 54. The side clamps 56 are L-shaped. One end of the side clamps 56 is fixed to the side wall of the pressure bearing shaft 54, and the other end of the side clamps 56 is vertically upward. The top end of the pressure bearing shaft 54 ​​extends upward into the mounting inner hole 3 and slides into the mounting inner hole 3. The top of the inner cavity of the side mounting shell 4 is fixedly provided with mounting inner plates 51 on the left and right sides respectively.

The side locking positioning plate 81 is rotatably mounted inside the mounting plate groove 85 via a hinge.

The outer end of the side mounting shaft 89 is rotatably connected to a rotating hole provided on the inner wall of the mounting plate groove 85. A torsion spring 88 is sleeved on the side mounting shaft 89, with one end fixed to the side mounting shaft 89 and the other end fixedly connected to the groove wall of the corresponding side of the mounting plate groove 85. The bottom slider 84 has an inner hole, and a built-in spring 83 and a positioning pin 82 are placed inside the inner hole. One end of the built-in spring 83 presses against the bottom of the inner hole, and the bottom end of the positioning pin 82 presses against the top end of the built-in spring 83. The positioning pin 82 slides in conjunction with the inner hole of the bottom slider 84, and the top end of the positioning pin 82 extends out of the inner hole of the bottom slider 84.

When the blasting detonator is not in use, the signal receiving area of ​​the detonator can be shielded by the adjusting signal shield 10 to avoid misoperation control and greatly ensure the safety of the blasting detonator application. At the same time, this blasting method first collects and analyzes a lot of information in the blasting area, thereby obtaining a lot of information to provide a theoretical basis for subsequent blasting.

[0039] The deep-hole drilling and blasting method in this combined mining process includes the following steps: Figure 6 As shown:

[0040] S1. First, acquire various types of information about the blasting area, and then analyze the acquired information. The acquired information mainly includes: the geographical location of the blasting area, the geological information of the blasting area, the information of the facilities around the blasting area, and the area information of the blasting area.

[0041] S2. Based on the obtained information, calculate the appropriate blasting depth and conduct data simulation tests on the data.

[0042] S3. The blasting process is further divided into four to six stages, with each stage using a different number of blasting detonators.

[0043] S4. Based on the divided stages, plan the number of blasting detonators to be used in each stage. The number of blasting detonators in each stage is 6-10.

[0044] S5. According to the planned data, the detonators are first assembled by combining them in pairs. During assembly, the side mounting shells of the two detonators are pressed tightly together. The bottom slide rails 7 of the two pressed side mounting shells are placed in the mounting grooves 86 of the bottom slider 84 and slide in cooperation with the mounting grooves 86. The bottom surfaces of the two pressed side mounting shells 4 are tightly fitted with the top surface of the side locking positioning plate 84. At this time, the side pull ring 87 of the side pull detonator connecting assembly 8 is pulled, thereby pulling the bottom slider 84 to slide until the bottom slider 84 slides until the side locking positioning plate 81 no longer contacts the bottom surfaces of the two assembled detonator side mounting shells 4. At this time, the side locking positioning plate 81 can be rotated outward by the side mounting shaft 89 under the action of the torsion spring 88 until the side locking positioning plate 81 is at a right angle. In order to achieve the rotation of the side locking positioning plate 81 to the vertical position, it can be achieved by a page, or a baffle can be set on the outside of the rotating side of the side locking positioning plate 81. After the side locking positioning plate 81 is rotated to the vertical position, the side locking positioning plate 81 will be close to the baffle. At this point, push the bottom slider 84 back so that the side positioning plate 81 fits against the side of the leftmost side mounting shell 4 in the assembly of the detonator. During the movement of the bottom slider 84, the positioning pin 82 will also directly engage with the bottom hole of the rightmost side mounting shell 4 in the assembly of the detonator, thus completing the combination of the two detonators.

[0045] S6. According to the stage division, carry the corresponding number of detonators and install them in the deep hole. During installation, the side mounting shell 4 of the combined detonator can be directly inserted upward into the groove of the deep hole. At this time, the bearing shaft 54 ​​of the quick positioning component 5 is squeezed and displaced downward. The bearing shaft 54 ​​can simultaneously drive the side clamp 56 to move downward. At this time, the top of the side clamp 56 will directly disengage from the bottom hole set on the bottom surface of the side clamp 52. At this time, the side clamp 52 between the two side mounting shells 4 of the assembled detonator will not be pushed out due to the obstruction of the shells. The side top springs 53 on the outermost left and right sides of the two side mounting shells 4 of the assembled detonator will lose their restraint and push out the side clamp 52 and insert it into the deep hole groove, thus completing the quick installation of the detonator before blasting. The above method completes the quick installation of the detonator before blasting without the use of additional tools and parts, which is particularly suitable for this kind of deep hole installation operation and greatly improves the application effect of the blasting detonator.

[0046] S7. After installation, rotate the signal shielding cover 10 to move it forward on the detonator controller 6 until the signal receiving position of the detonator controller 6 is exposed and no longer shielded.

[0047] S8. Evacuate the site and control the blasting.

[0048] In this embodiment, a drill probe 1 is fixedly installed at the front end of the explosive detonator 2. The drill probe 1 is used to assist in soil breaking when a certain degree of soil breaking is required. The bottom surface of the mounting shell 4 is provided with bottom slide rails 7 near the front and rear sides, and the top surface of the bottom slider 84 is provided with mounting grooves 86 near the front and rear sides. The two bottom slide rails 7 on the bottom surface of the side mounting shell 4 correspond one-to-one with the mounting grooves 86 on the top surface of the bottom slider 84 and slide in cooperation, so that the mounting shell 4 slides more smoothly on the bottom slider 84.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.

At this time, the top of the side clamp (56) will directly disengage from the limiting hole set on the bottom surface of the side clamp (52). At this time, the side clamp (52) between the two side mounting shells (4) of the assembled detonator will not be pushed out due to mutual obstruction. The side top springs (53) on the outermost left and right sides of the two side mounting shells (4) of the assembled detonator will lose their restriction and push out the side clamp (52) and insert it into the deep hole groove, thus completing the quick installation of the detonator before blasting. S7. After installation, rotate the signal shield (10) to drive the signal shield (10) to move forward on the detonator controller (6) until the signal receiving position of the detonator controller (6) is exposed and no longer shielded. S8. Evacuate the site and control the blasting.

2. The deep-hole drilling and blasting method in combined mining according to claim 1, characterized in that, The front end of the blasting detonator (2) is fixedly equipped with a drill probe (1).

3. The combined mining deep-hole drilling and blasting method according to claim 1 or 2, characterized in that, The bottom surface of the side mounting shell (4) is provided with bottom slide rails (7) near the front and rear sides respectively, and the top surface of the bottom slider (84) is provided with mounting grooves (86) near the front and rear sides respectively. The two bottom slide rails (7) on the bottom surface of the side mounting shell (4) correspond one-to-one with the mounting grooves (86) on the top surface of the bottom slider (84) and slide together.
