Description

Technical Field

[0001] This invention belongs to the field of open-pit mining technology, and in particular relates to a blasting mining device for deep open-pit mines with water-bearing blast holes. Background Technology

[0002] In open-pit mining, blasting is a key process for breaking rock and stripping overburden. Deep open-pit mines are the mainstream type of open-pit mining. As the mining depth increases, the terrain of the pit continues to decline, and the bottom of the pit is prone to the accumulation of groundwater, rainwater and surface runoff, which is the main area where water-bearing blasting conditions occur in open-pit mines.

[0003] Regarding the issue of loading explosives into water-bearing blast holes, the existing operating procedure typically involves workers transporting several explosives in waterproof packaging to the blasting site one by one. During loading, individual explosive cartridges must be placed into the blast holes sequentially. Since each blast hole requires multiple explosives, operators need to repeatedly grab and drop the explosives, which not only slows down the loading speed and reduces the overall efficiency of mining operations, but also causes enormous physical exertion for the workers. In severe cases, fatigue may lead to operational errors, further deteriorating the blasting quality and seriously affecting the overall construction effect of rock stripping and ore mining in deep open-pit mines.

The number of first special tubes can be adjusted according to different blast hole depths, making it highly adaptable and solving the problem of limited adaptability in traditional devices. The overlapping and enclosed splicing of several first and second special tubes effectively isolates water inside the blast hole from contact with explosives and detonators, preventing blasting failure due to water immersion and ensuring the reliability of blasting operations.

[0016] 2. The length-graded telescopic structure of the present invention can flexibly adjust the length of a single first special tube or second special tube. The first special tube or second special tube is designed by splicing multiple tubes to adapt to boreholes of different depths, thus solving the problem that traditional explosive loading devices cannot adapt to boreholes of multiple depths.

[0017] 3. The third and fourth arc-shaped blocks of the present invention can assist in clamping the first and second special tubes with long splicing lengths, preventing the first and second special tubes from bending or falling off due to excessive length, ensuring the safety of the first and second special tubes during assembly. When the blast hole is deep, a second special tube can be spliced ​​at both the bottom and middle, which can shorten the time difference between the bottom and top blasting during blasting, so as to arrange and combine the first and second special tubes in combination with specific blasting methods.

[0022] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0023] Please see Figures 1 to 16 This invention provides a blasting mining device for deep-pitted open-pit mines with water-bearing blast holes, the blasting mining device comprising: A mobile chassis 101, wherein a rotating platform 102 is rotatably mounted on the upper surface of the mobile chassis 101; A plurality of pipe caps 501, a first special pipe and a second special pipe, wherein the plurality of pipe caps 501 are all disposed on a rotating platform, and the plurality of first special pipes and second special pipes are all disposed on a rotating platform 102, wherein a support frame 201 is installed at the bottom of each first special pipe, and explosives are placed on the support frame 201 inside each first special pipe, wherein the bottom of each second special pipe is sealed, and a detonator and explosives are placed inside each second special pipe; The pre-assembly unit includes a clamping plate 401, a second lifting module, and a first transverse telescopic module.

The second lifting module is disposed on the rotating platform 102, and the telescopic direction of the second lifting module is perpendicular to the upper end face of the rotating platform 102. Under the action of the second lifting module and the first transverse telescopic module, the clamping plate 401 can close and splice the pipe cap 501 onto the first special pipe. Under the action of the second lifting module, the clamping plate 401 can close and splice several first special pipes and one second special pipe overlapping vertically from top to bottom according to the depth of the blast hole. The explosive loading unit includes a first lifting module. The fixed end of the first lifting module is disposed on the first transverse telescopic module. The extended end of the first lifting module is fixedly connected to the clamping plate 401. The telescopic direction of the first lifting module is perpendicular to the upper surface of the rotating platform 102. Under the action of the first lifting module and the second lifting module, the clamping plate 401 can load several first special tubes and one second special tube, which are closed and spliced ​​from top to bottom, into the blast hole.

[0024] In this embodiment, when explosives need to be filled during blasting mining of water-bearing boreholes in deep open-pit mines, the movable chassis 101 moves to the location where explosives are to be filled. Under the action of the second lifting module, the clamping plate 401 clamps out the pipe cover 501. Then, under the action of the second lifting module and the first lateral telescopic module, the clamping plate 401 seals and splices the pipe cover 501 onto the first special pipe. The first special pipe moves upward under the action of the second lifting module. Then, the first special pipe is followed by the next first special pipe and sealed and spliced ​​vertically.

Under the action of the second lifting module, the bottommost first special pipe of the several vertically and vertically sealed and spliced ​​first special pipes is sealed and spliced ​​onto the second special pipe. Finally, the several sealed and spliced ​​first special pipes and one second special pipe are filled into the borehole under the action of the second lifting module and the first lifting module.

[0025] This invention uses a second lifting module to drive a clamping plate 401 to overlap and splice several first special tubes and one second special tube. The first and second lifting modules can then be used to enclose and splice these overlapping first and second special tubes into a blast hole in one go. The number of first special tubes can be adjusted according to different blast hole depths, making it highly adaptable and solving the problem of limited adaptability in traditional devices. The overlapping and enclosed splicing of the first and second special tubes effectively isolates water inside the blast hole from contact with explosives and detonators, preventing blasting failure due to water immersion and ensuring the reliability of blasting operations. Furthermore, the entire process can be completed without manual handling of explosives, completely avoiding personnel contact with explosives and significantly improving operational safety.

The upper outer diameter of the first mounting tube 210 is the same as the inner diameter of the second circular groove 504. The upper outer side wall of the first mounting tube 210 is provided with a first snap-fit ​​groove 217. When the tube cover 501 closes the upper opening of the first mounting tube 210, the first buckle 508 is snapped into the first snap-fit ​​groove 217, and the first circular sealing ring 505 is pressed and adhered to the upper end face of the first mounting tube 210.

The lower part of the second buckle 222 away from the end face of the fourth spring 221 is provided with a fourth guide slope 223. When the first annular tube 218 on one of the first special tubes or the second special tubes is sleeved on the upper part of the first mounting tube 210 on the other first special tube or the second special tube, the second buckle 222 is engaged in the first snap-fit ​​groove 217, and the upper end face of the first mounting tube 210 on the other first special tube or the second special tube is pressed and adhered to the third circular sealing ring 219. The support frame 201 is installed at the bottom of the first telescopic tube 211 on the first special tube, and the bottom of the first telescopic tube 211 on the second special tube is closed.

[0036] In this embodiment, since the depth data of all blast holes has been recorded when the blast holes are dug, the first and second special tubes can be extended to a suitable length through a length-graded telescopic structure based on the known depth data of all blast holes. This allows the combination of the first and second special tubes to adapt to all blast hole depths. Specifically, before loading the first special tube with explosives, the first telescopic tube 211 is stretched from the first mounting tube 210 to a designated position. Then, the first pin 214 is simultaneously rotated into the first threaded through hole 215 and the second threaded hole 216 at that position. Explosives are then loaded into the first special tube. Before loading the second special tube with explosives, the first telescopic tube 211 is stretched from the first mounting tube 210 to a designated position. Then, the first pin 214 is simultaneously rotated into the first threaded through hole 215 and the second threaded hole 216 at that position. Then, a detonator is first loaded into the second special tube. The junction between the detonator lead and the outer wall of the first tube is sealed with sealant. Explosives are then loaded into the second special tube. When the pipe cap 501 is closed and spliced ​​on the first special pipe, the pipe cap 501 is snapped into the first snap groove 217 on the first special pipe by the first buckle 508, and at the same time, the first circular sealing ring 505 on the pipe cap 501 is pressed and adhered to the upper end face of the first mounting tube 210 on the first special pipe. When one of the first special tubes is spliced ​​onto the other first special tube, one of the first special tubes is snapped into the first snap groove 217 on the other first special tube by the second snap 222, and at the same time, the second circular sealing ring 213 on one of the first special tubes is pressed and adhered to the upper end face of the first mounting tube 210 on the other first special tube. When the first special tube is spliced ​​onto the second special tube, the first special tube is snapped into the first snap groove 217 on the second special tube by the second buckle 222, and at the same time, the second circular sealing ring 213 on the first special tube is pressed and adhered to the upper end face of the first mounting tube 210 on the second special tube. When the second special tube is spliced ​​onto the first special tube, the second special tube is snapped into the first snap groove 217 on the first special tube by the second buckle 222, and at the same time, the second circular sealing ring 213 on the second special tube is pressed and adhered to the upper end face of the first mounting tube 210 on the first special tube.

[0037] The length-graded telescopic structure of this invention can flexibly adjust the length of a single first or second special tube. The first or second special tube is designed by splicing multiple tubes to adapt to boreholes of different depths, thus solving the problem that traditional explosive loading devices cannot adapt to boreholes of multiple depths.

[0038] Please see Figure 1 , Figure 9 and Figure 10 The pre-assembly unit also includes a third mounting block 402 and a bidirectional telescopic power source 403; the second lifting module includes a second lifting power source 405 and a mounting frame 409; and the first transverse telescopic module includes a first transverse telescopic power source 406 and a sixth mounting block 410.

[0039] In this embodiment, when the pipe cap 501 needs to be spliced ​​onto the first special pipe, the second lifting power source 405 first moves the clamping plate 401 downward into the first circular groove 503 of the uppermost pipe cap 501 inside the first mounting cylinder 502. Then, the bidirectional telescopic power source 403 extends so that the side wall of the clamping plate 401 presses against the side wall of the first circular groove 503, that is, the clamping plate 401 clamps the pipe cap 501. Then, the second lifting power source 405 moves the pipe cap 501 clamped by the clamping plate 401 upward. After that, the first lateral telescopic movement... The power source 406 moves the pipe cap 501 clamped by the clamping plate 401 to directly above the first through hole 103. When the first special tube is clamped between the first through hole 103 and the pipe cap 501 clamped by the clamping plate 401 under the clamping of the first arc block 301 and the second arc block 302, the second lifting power source 405 will move the clamping plate 401 downward until the first buckle 508 on the pipe cap 501 is engaged in the first snap-fit ​​groove 217 on the first special tube, that is, the pipe cap 501 is sealed and spliced ​​on the first special tube, waiting for subsequent operations.

[0040] Please see Figure 1 , Figure 9 and Figure 10 The first lifting module includes a first lifting power source 404; The first lifting power source 404 is not limited here; its function is to provide extension and retraction power, and it can be a cylinder, hydraulic cylinder, etc. The extended end of the first lifting power source 404 is fixedly installed on the third mounting block 402.

[0041] In this embodiment, when a number of first special tubes and a second special tube are overlapped and sealed together and need to be filled into the borehole, the first special tubes and the second special tube are filled into the borehole from bottom to top under the action of the extension of the first lifting power source 404 and the action of the second lifting power source 405.

[0042] Please see Figure 1 , Figure 7 and Figure 8 The blasting and mining device also includes a third telescopic power source 701, a fourth mounting block 702, a left and right rotating ball screw 703, a third arc block 704, and a fourth arc block 705; The third telescopic power source 701 is not limited here; its function is to provide telescopic power, and it can be a cylinder, hydraulic cylinder, etc. The third arc-shaped block 704 is fixedly installed on the extended end of one end of the left and right rotating ball screw 703, the fourth arc-shaped block 705 is fixedly installed on the extended end of the other end of the left and right rotating ball screw 703, the fixed end of the left and right rotating ball screw 703 is horizontally installed on the fourth mounting block 702, the fourth mounting block 702 is fixedly installed on the extended end of the third telescopic power source 701, the telescopic direction of the third telescopic power source 701 is perpendicular to the upper end face of the rotating platform 102, and the fixed end of the third telescopic power source 701 is fixedly installed on the rotating platform 102. The first mounting base 303 is provided with a third sliding groove 706, the sliding guide direction of the third sliding groove 706 is parallel to the extension direction of the third telescopic power source 701, and the fourth mounting block 702 is slidably disposed in the third sliding groove 706. The upper surfaces of the third arc-shaped block 704 and the fourth arc-shaped block 705 are both higher than the upper surface of the first arc-shaped block 301. The inner walls of the third arc-shaped block 704 and the fourth arc-shaped block 705 are arranged opposite to each other. The third arc-shaped block 704 and the fourth arc-shaped block 705 can clamp the first special tube or the second special tube that is located directly above the first through hole 103 and is closed and spliced. The length of the third chute 706 is greater than the maximum height of the first or second special tube after it has been extended or retracted through the length-grading telescopic structure.

[0043] In this embodiment, when assembling explosives according to the depth of the borehole, the second lifting power source 405 first moves the clamping plate 401 downward into the first circular groove 503 of the uppermost tube cap 501 inside the first mounting cylinder 502. Then, the bidirectional telescopic power source 403 extends so that the side wall of the clamping plate 401 presses against the side wall of the first circular groove 503, that is, the clamping plate 401 clamps the tube cap 501. Then, the second lifting power source 405 moves the tube cap 501 clamped by the clamping plate 401 upward. After that, the first transverse telescopic power source 406 moves the tube cap 501 clamped by the clamping plate 401 to directly above the first through hole 103. At this time, the first special tube conveyed by the first conveyor belt 202 is in the first arc block 301 and the second arc block 302. The first special tube is clamped between the first through hole 103 and the clamping plate 401. The second lifting power source 405 moves the clamping plate 401 downward until the first buckle 508 on the pipe cover 501 engages with the first snap-fit ​​groove 217 on the first special tube, thus sealing the pipe cover 501 onto the first special tube. Then, the first arc block 301 and the second arc block 302 release the first special tube. After that, the second lifting power source 405 moves the pipe cover 501 and the first special tube clamped by the clamping plate 401 upward to the height of the first special tube. Then, the second special tube conveyed by the first conveyor belt 202 is clamped between the first arc block 301 and the second arc block 302 and the pipe cover 501 located between the first through hole 103 and the clamping plate 401. Between the first special tube and the second special tube, the third arc block 704 and the fourth arc block 705, driven by the left and right rotating ball screw 703, release the first special tube. Then, the second lifting power source 405 moves the clamping plate 401 downward until the second buckle 222 on the first special tube engages with the first engaging groove 217 on the second special tube, thus sealing the first special tube onto the second special tube. Afterward, the third arc block 704 and the fourth arc block 705, driven by the left and right rotating ball screw 703, clamp the first special tube. Then, the first arc block 301 and the second arc block 302 release the second special tube. The first and second special tubes are then connected by the second lifting power source 405. Under the action of the third telescopic power source 701, the first special tube rises synchronously to the height of the first special tube. Then, the third first special tube, conveyed by the first conveyor belt 202, is clamped between the first through hole 103 and the second first special tube by the clamping of the first arc block 301 and the second arc block 302. Then, the second lifting power source 405 moves the clamping plate 401 downward until the second buckle 222 on the second first special tube engages in the first engaging groove 217 on the third first special tube. At this time, the third arc block 704 and the fourth arc block 705 move downward synchronously under the action of the third telescopic power source 701. Afterward, the third arc block 704 and the fourth arc block 705 release the first first special tube under the action of the left and right rotating ball screw 703.Then, under the action of the third telescopic power source 701, the third arc-shaped block 704 and the fourth arc-shaped block 705 move downwards by the height of one first special tube. Then, under the action of the left and right rotating ball screw 703, the third arc-shaped block 704 and the fourth arc-shaped block 705 clamp the second first special tube. Then, the first arc-shaped block 301 and the second arc-shaped block 302 release the third first special tube. The first, second, and third first special tubes then rise synchronously to the height of one first special tube under the action of the second lifting power source 405 and the third telescopic power source 701. The above steps are repeated to create a sealed combination of several first special tubes and several second special tubes. If the borehole depth is shallow, only one second special tube is joined at the bottom, with the rest being first special tubes. If the borehole depth is deep, a second special tube is joined at both the bottom and the middle, achieving combined blasting.

[0044] The third arc-shaped block 704 and the fourth arc-shaped block 705 of the present invention can assist in clamping the first and second special tubes with long splicing lengths, preventing the first and second special tubes from bending or falling off due to excessive length, ensuring the safety of the first and second special tubes during assembly. When the blast hole depth is deep, a second special tube can be spliced ​​at both the bottom and the middle, which can shorten the time difference between the bottom and the top during blasting, so as to arrange and combine the first and second special tubes in combination with specific blasting methods.

[0045] Please see Figure 13 The first limiting module and the second limiting module both include a fifth mounting block 801, a pressing block 802 and a fifth spring 803; The fifth mounting block 801 is fixedly installed at the lower part of the first special tube or the second special tube.

The sliding guide direction of the third sliding groove 804 is set horizontally. One end of the fifth spring 803 is fixedly connected in the third sliding groove 804. The fifth spring 803 is set horizontally. The other end of the fifth spring 803 is fixedly connected with a pressing block 802. The pressing block 802 is slidably arranged in the third sliding groove 804. The lower part of the pressing block 802 away from the end face of the fifth spring 803 is provided with a fifth guide slope 807. When the first special tube or the second special tube is inserted into the blast hole, the pressing block 802 compresses the fifth spring 803 and presses it against the side wall of the blast hole.

[0046] In this embodiment, after assembling several first and second special tubes, the third arc-shaped block 704 and the fourth arc-shaped block 705 clamp the second-to-last first special tube from bottom to top, while the first arc-shaped block 301 and the second arc-shaped block 302 clamp the lowest second special tube. At this point, the assembled first and second special tubes need to be filled into the borehole. Specifically, the third arc-shaped block 704 and the fourth arc-shaped block 705 release the second-to-last first special tube from bottom to top, and under the action of the third telescopic power source 701, the third arc-shaped block 704 and the fourth arc-shaped block 705 move upwards... After reaching the height of the first special tube, the third arc-shaped block 704 and the fourth arc-shaped block 705 clamp the third-to-last first special tube from bottom to top. Then, the first arc-shaped block 301 and the second arc-shaped block 302 release the bottommost second special tube. Subsequently, several first and second special tubes move down synchronously by the second lifting power source 405 and the third telescopic power source 701, reaching the height of one first special tube. Then, the first arc-shaped block 301 and the second arc-shaped block 302 clamp the second-to-last first special tube from bottom to top, and the third arc-shaped block 704 and the fourth arc-shaped block 705 release the third-to-last first special tube from bottom to top. The third first special tube, the third arc block 704, and the fourth arc block 705, under the action of the third telescopic power source 701, move upward by the height of one first special tube. Then, the third arc block 704 and the fourth arc block 705 clamp the fourth first special tube from the bottom up. Next, the first arc block 301 and the second arc block 302 release the second-to-last first special tube from the bottom up. Afterwards, several first and second special tubes, under the action of the second lifting power source 405 and the third telescopic power source 701, synchronously move downward by the height of one first special tube, repeating the above steps. During the process, when the second lifting power source 405 reaches its lowest extension stroke, the first lifting power source 404 replaces the second lifting power source 405 to drive several first special tubes and second special tubes into the borehole until all the first special tubes and second special tubes are placed into the borehole. When the first special tube or the second special tube enters the borehole, the pressing block 802 on the first special tube or the second special tube contacts the side wall of the borehole and compresses the fifth spring 803 and presses it against the side wall of the borehole. During the process of filling the borehole with explosives, the workers pull the fuse of the detonator in the second special tube to the ground.

[0047] The third arc-shaped block 704 and the fourth arc-shaped block 705 of this invention can assist in clamping the first and second special tubes, which have a relatively long splicing length, when the explosive is filled into the borehole. This prevents the first and second special tubes from bending or falling off due to their excessive length, ensuring the integrity and safety of the first and second special tubes during the filling process. In addition, multiple pressing blocks 802 are circumferentially distributed on the first and second special tubes, providing uniform radial support force for the first and second special tubes. This ensures that the first and second special tubes remain centered and stable in the borehole and will not be blown out by the water pressure in the borehole after being placed in. The structure is ingeniously designed.

[0049] In this embodiment, the blast holes drilled in the blasting area are first arranged in rows and columns. A notch 908 for hole positioning is marked on the upper end face of the blast hole plug 907 near its inner diameter, indicating that the blast hole is in the first row. Two notches 908 for hole positioning are marked on the upper end face of the blast hole plug 907 near its inner diameter, indicating that the blast hole is in the second row, and so on. Similarly, a notch 908 for hole positioning is marked on the upper end face of the blast hole plug 907 near its outer diameter, indicating that the blast hole is in the first column, and two notches 908 for hole positioning are marked on the upper end face of the blast hole plug 907 near its outer diameter, indicating that the blast hole is in the second column, and so on. Each blast hole plug... The notch 908 on the muzzle plug 907 corresponds to the depth of the borehole at that location. Before the explosive is loaded, the movable chassis 101 is first moved until the second mounting cylinder 901 is directly above one of the borehole muzzle plugs 907. The camera 909 identifies the number of notches 908 on the borehole muzzle plug 907, thus determining the depth of the borehole. Then, two opposing fifth telescopic power sources 904 move the corresponding second arc-shaped clamping blocks 905 downwards to the position to clamp the borehole muzzle plug 907. Then, two opposing sixth telescopic power sources 910 move the second arc-shaped clamping blocks 905 relative to each other to the upper part of clamping the borehole muzzle plug 907. Finally, the two opposing fifth telescopic power sources 904 move the corresponding second arc-shaped clamping blocks 905 downwards... After moving upwards to the initial position, the two opposing fourth telescopic power sources 902 move the corresponding first arc-shaped clamping blocks 903 relative to each other to clamp the lower part of the borehole muzzle plug 907, thus removing the borehole muzzle plug 907 from the borehole. When it is necessary to remove the next borehole muzzle plug 907, firstly, the two opposing sixth telescopic power sources 910 move the second arc-shaped clamping blocks 905 away from each other to release the upper part of the borehole muzzle plug 907. Then, the two opposing fifth telescopic power sources 904 move the corresponding second arc-shaped clamping blocks 905 downwards to the position to clamp the next borehole muzzle plug 907. Then, the two opposing sixth telescopic power sources 910 move the second arc-shaped clamping blocks 905 relative to each other to clamp the borehole muzzle plug 907. The upper part of the borehole muzzle plug 907 is then moved upward by two opposing fifth telescopic power sources 904, which move the corresponding second arc-shaped clamping block 905 upward to below the previous borehole muzzle plug 907, so that the upper end face of the borehole muzzle plug 907 is in contact with the lower end face of the previous borehole muzzle plug 907. Then, two opposing fourth telescopic power sources 902 move the corresponding first arc-shaped clamping block 903 away from each other to release the lower part of the borehole muzzle plug 907 and move it away from directly above the borehole muzzle plug 907. Then, the two opposing fifth telescopic power sources 904 continue to move the corresponding second arc-shaped clamping block 905 upward to the initial position, so that both of the overlapping borehole muzzle plugs 907 are moved into the second mounting cylinder 901.During the removal of each borehole muzzle plug 907, the first and second special tubes are sealed and spliced ​​in corresponding numbers according to the depth of the borehole. After the borehole muzzle plug 907 is removed, the rotating platform 102 rotates 180 degrees under the action of the rotating power source 104, so that the first through hole 103 is located directly above the borehole. After the first and second special tubes are sealed and spliced, they can be inserted into the borehole.

[0050] The temporary clamping module and the plug removal module of this invention work together to realize the automated removal and placement of the borehole muzzle plug 907 without manual operation, avoiding the risk of personnel falling near the edge of the borehole. At the same time, it protects the borehole muzzle plug 907 from damage and can be reused. Furthermore, while removing the borehole muzzle plug 907, this invention can simultaneously seal and splice the first and second special tubes in the corresponding number according to the depth of the borehole, reducing the time required for work and increasing the efficiency of explosive loading.
