Description

Technical Field

[0001] The invention relates to the technical field of filling mining, and in particular to a device and method for filling mining using two liquids of gangue paste and gelling material in separate sources. Background Art

[0002] Gangue paste and cementitious material filling mining is a mining method that processes the gangue, fly ash, slag, inferior soil, urban solid waste, etc. near the coal mine into aggregates of a certain grade, mixes them with cementitious materials and water into a paste slurry, and transports it underground through a pipeline to fill the goaf in real time. This method can not only effectively control surface subsidence, but also recycle coal resources and reduce environmental pollution.

[0003] However, in the prior art, when filling gangue paste and cementitious materials, the gangue paste and the cementitious materials added with a curing agent are mostly mixed with each other by a mixer before pumping, and then the filling pipe is penetrated through the mining equipment to the filling position of the underground hole to fill the gangue paste. However, when the gangue paste in the conveying pipeline contains a curing agent, such gangue paste must be flushed if it stays for more than 4 hours, otherwise it will solidify. In the actual working process, it will be necessary to flush the pipeline after each shift is completed, which not only greatly reduces the filling efficiency of the gangue paste, but also frequently inserts and pulls the filling pipeline into the underground hole, which not only increases the wear of the pipeline and easily causes damage to the pipeline, but also frequently rubs the hole wall of the underground hole, which easily damages the wall protective layer of the hole wall, thereby increasing the risk of collapse of the hole wall.

[0014] The method for mining by using two liquids of gangue paste and gelling material for separate source filling uses the above-mentioned two liquids of gangue paste and gelling material for separate source filling and mining, and comprises the following steps: Step 1, pipeline transportation. When transporting the filling pipeline to the underground mining position, select the filling pipeline corresponding to the pipeline docking pipe one by one, connect one end of the filling pipeline with the pipeline docking pipe, and then thread the drill driving pipe in the filling docking joint group with the male joint of the mining and transportation drill rod in the filling docking rod group, insert the drill rod limit block into the limit groove, and then thread the mining and transportation drill rods in multiple filling docking rod groups in sequence through the mining drilling equipment to form a filling device extending to the inside of the borehole. After the filling docking joint group and the filling docking rod group enter the inside of the borehole, the filling pipeline driven by the filling docking joint is clamped in the corresponding pipeline placement groove 1, pipeline placement groove 2 and pipeline placement groove 3; Step 2: Pipeline drilling: When the filling joint assembly and the filling joint rod assembly are driven to be transported into the borehole by the mining drilling equipment, the positioning cylinder is started, and the output end of the positioning cylinder drives the positioning block to move, so that the positioning roller on the positioning block contacts the pipeline protection casing, and then the mining drilling equipment drives the mining and conveying drill rod to rotate, and the rotation of the mining and conveying drill rod drives the drill bit driving pipe to rotate, and the rotation of the drill bit driving pipe drives the hollow drill bit to rotate through the mixing partition; Step three, pipeline limiting, through the mining drilling equipment and the docking positioning group, the two filling docking rod groups are docked, as the male joint and the female joint of the mining and conveying drill rod in the filling docking rod group are threadedly connected, one of the drill rod limiting blocks will squeeze the adjacent pipeline limiting block, and the inflatable sliding rod in the pipeline limiting block will be inserted into the corresponding limiting docking groove, as the drill rod limiting block contacts the pipeline limiting block, the inflatable sliding rod will drive the inflatable sliding block to move, and the movement of the inflatable sliding block will compress the gas in the inflation area into the clamping limiting box through the inflation pipe, when the air pressure in the clamping limiting box increases, the clamping frame will move to the side away from the clamping limiting box, so that the clamping frame moves to the pipeline placement slot 1, and the position of the filling pipeline is fixed; Step 4, dual-liquid separate source filling, after the filling joint group is transported to the position required for filling and mining in the borehole through the mining drilling equipment, the mining drilling equipment will not drive the position of the filling joint group to move, and the mining drilling equipment will continue to drive the mining and conveying drill rod and the hollow drill bit to rotate, and then the gangue paste and gel material will be pumped through the corresponding filling pipelines according to the proportion. The pumped gangue paste and gel material will pass through the filling pipeline and the pipeline docking tube, mix and gather in the mixing area, and with the rotation of the hollow drill bit, be discharged through the discharge through hole to fill the underground holes.

[0015] The beneficial effects of the present invention are: 1. The present invention only needs to select a corresponding number of filling docking stem groups and a corresponding length of filling pipe when filling the underground with gangue paste and gel material at different depths. The detachable docking between the filling docking rod group and the filling docking head group is not only convenient to carry, but also easy to install; 2. In the present invention, when the filling pipe is transported into the borehole by the mining equipment, the mud is transported into the mining delivery drill rod by the mining drilling equipment, and the mud enters the slurry discharge area through the drill bit driving pipe, and finally discharged through the slurry discharge through hole. The discharged mud can repair the collapsed hole in the borehole under the rotation of the alloy head, and at the same time, the discharged mud can form a wall protection effect on the hole, increase the stability of the hole wall, and facilitate the transportation of the filling pipe; 3. The present invention uses the mining drilling equipment and the docking positioning group to make two filling docking rod groups docked. Not only can the filling pipeline be positioned in the pipeline placement groove 1 through the movement of the clamping frame to achieve the clamping and fixing of the pipeline, but also when the inflatable slide bar is inserted into the limit docking groove, the positions of the pipeline protection sleeve, the pipeline limit block and the drill rod limit block in the two adjacent filling docking rod groups can be spliced ​​and fixed at the same time, which can effectively avoid the risk of the pipeline protection sleeve being driven to move synchronously when the mining and conveying drill rod rotates, causing the filling pipeline to be twisted; 4. In the present invention, when conveying the gangue paste and the gel material, a corresponding number of filling pipes can be selected according to different proportions to pump the filling materials, and the gangue paste and the gel material will enter the rotating hollow drill bit after being pumped to be mixed, and will be discharged through the discharge through hole to fill the underground holes. The filling material discharged through the discharge through hole can also achieve the effect of mixing under the rotation of the alloy head. Even after the work is completed, there is no need to extract the filling pipeline, and the rotation of the hollow drill bit can be accelerated by the mining drilling equipment, and the mixed filling material in the mixing area can be discharged under the action of centrifugal force. At the same time, mud can be pumped through the mining drilling equipment to increase the pressure near the hollow drill bit, so that the mud can flow back into the mixing area through the discharge through hole, thereby preventing the mixing of the raw materials in the pipes. Different from the traditional filling method, the present application can use a wear-resistant hose such as a steel wire hose to transport the filling material, which not only has low requirements on the quality of the filling pipe, but is also easy to carry. During the filling process, there is no need to frequently plug, unplug and clean the filling pipe, and the filling efficiency and filling safety are high. Even if part of the hole wall collapses during the filling stage, the hole can be expanded by rotating the hollow drill bit and the filling joint group can be pulled out.

The drill rod limit assembly is arranged on the other side of the pipeline protection casing 1, and the drill rod limit assembly is located on one side of the male joint of the mining and conveying drill rod 2, which is used to fix the mining and conveying drill rod 2.

[0022] Among them, the pipeline limiting assembly includes a pipeline limiting block 3 and a pipeline clamping part. The pipeline limiting block 3 is arranged on the pipeline protective casing 1. The mining and conveying drill rod 2 passes through and is rotatably arranged on the pipeline limiting block 3. A plurality of pipeline placement grooves 2 are opened on the pipeline limiting block 3. The pipeline placement grooves 2 correspond to the pipeline placement grooves one by one. There are multiple pipeline clamping parts. The pipeline clamping parts are embedded in the pipeline limiting block 3, and the pipeline clamping parts are located between two adjacent pipeline placement grooves 2, which are used to limit the filling pipeline placed in the pipeline placement grooves 2. The pipeline clamping part includes a clamping limiting box 4, a clamping frame 5, an inflation box 6, an inflation slider 7, an inflation slide bar 9 and an inflation return spring 10. The clamping limiting box 4 is arranged in the pipeline limiting block 3. There are two clamping frames 5, and the two clamping frames 5 are symmetrical. It is arranged that one end of the clamping frame 5 passes through and is sealed and slidably arranged in the clamping limit box 4, the other end of the clamping frame 5 passes through the pipeline placement groove 2, and the clamping frame 5 is slidably arranged in the pipeline limit block 3, the inflation box 6 is arranged in the pipeline limit block 3, the inflation slider 7 is sealed and slidably arranged in the inflation box 6, the inflation slider 7 divides the inflation box 6 into an inflation area and a reset area, an inflation pipe 8 is connected between the inflation area and the clamping limit box 4, the inflation pipe 8 is located in the pipeline limit block 3, a plurality of inflation slide bars 9 are provided, one end of the inflation slide bar 9 is arranged on the inflation slide bar 7, the other end of the inflation slide bar 9 passes through the reset area to the side of the inflation box 6 away from the pipeline protection sleeve 1, the inflation slide bar 9 is parallel to the mining and conveying drill pipe 2, and a reset groove is provided on the side of the inflation slider 7 close to the inflation area, and an inflation reset spring 10 is arranged between the reset groove and the inflation box 6, for resetting the position of the inflation slide bar 7.

[0023] Among them, the drill rod limiting assembly includes a drill rod limiting block 11 and a drill rod limiting part, the drill rod limiting block 11 is arranged on the pipeline protection casing 1, the mining and conveying drill rod 2 passes through and is rotatably arranged on the drill rod limiting block 11, a plurality of pipeline placement grooves three are opened on the drill rod limiting block 11, and the pipeline placement grooves three correspond one to one with the pipeline placement grooves, and a limiting docking groove adapted to the inflatable slide bar 9 is opened on the side of the drill rod limiting block 11 away from the pipeline protection casing 1, and the drill rod limiting part is provided with multiple, and a plurality of limiting through holes are opened on the drill rod limiting block 11, and the limiting through holes are located between two adjacent pipeline placement grooves three, and the limiting through holes correspond one to one with the drill rod limiting part, and the drill rod limiting part is arranged in the limiting through holes, and the drill rod limiting part includes a limiting rod 12 and a limiting spring 13, and the limiting rod 12 is slidably arranged in the limiting through hole, and the limiting spring 13 is arranged between the limiting rod 12 and the drill rod limiting block 11.

[0024] Specifically, when the inflation slide rod 9 is squeezed, the inflation slide rod 9 will drive the inflation slider 7 to move. The movement of the inflation slider 7 will compress the gas in the inflation area into the clamping limit box 4 through the inflation tube 8. When the air pressure in the clamping limit box 4 increases, the clamping frame 5 will move toward the side away from the clamping limit box 4, so that the clamping frame 5 moves to the pipeline placement groove 1 to fix the position of the filling pipeline. When the inflation slide rod 9 is not under force, under the action of the rebound force of the inflation return spring 10, the inflation slide rod 7 will be driven to reset, so that the gas in the clamping limit box 4 returns to the inflation box 6 through the inflation tube 8. When the air pressure in the clamping limit box 4 decreases, the clamping frame 5 will be contracted into the pipeline limit block 3 under the action of pressure, thereby facilitating the filling pipeline to be moved out of the pipeline placement groove 2.

[0025] As mentioned above, the filling joint assembly 002 is detachably connected with the filling joint rod assembly 001 through a thread, and is used to fill the underground filling mining position when the filling pipeline is transported, and is used to mix the transported gangue paste with the gel material. The filling joint assembly 002 includes a pipeline docking block 14, a hollow drill bit 16 and a drill bit driving pipe 18. The pipeline docking block 14 is provided with a limiting groove that is compatible with the drill rod limiting block 11. The pipeline docking block 14 is penetrated by a plurality of pipeline docking pipes 15, and the pipeline docking pipes 15 correspond to the pipeline placement grooves one by one. The hollow drill bit 16 and the drill bit driving pipe 18 are provided with a plurality of pipeline docking pipes 15. The pipeline docking pipes 15 correspond to the pipeline placement grooves one by one. 6 is sealed and rotatably arranged on the pipeline docking block 14, a mixing partition 17 is arranged in the hollow drill bit 16, the mixing partition 17 divides the hollow drill bit 16 into a mixing area and a slurry discharge area, the mixing area is connected to the pipeline docking tube 15, one end of the drill drive pipe 18 is sealed and arranged on the mixing partition 17, the drill drive pipe 18 is connected to the slurry discharge area, the other end of the drill drive pipe 18 passes through the limiting groove, the drill drive pipe 18 is rotatably arranged in the pipeline docking block 14, and a thread groove is opened in the drill drive pipe 18 to be threadedly connected to the mining and conveying drill rod 2.

[0026] It should be supplemented that the outer surface of the hollow drill bit 16 is provided with multiple alloy heads 19 for drilling by the hollow drill bit 16 , and the hollow drill bit 16 is provided with multiple discharge holes 20 connected to the mixing area, and the hollow drill bit 16 is also provided with multiple slurry discharge holes 21 connected to the slurry discharge area.

[0027] Specifically, when the filling pipeline is transported to the underground mining position, a filling pipeline corresponding to the pipeline docking tube 15 is selected, one end of the filling pipeline is connected to the pipeline docking tube 15, and then the drill drive tube 18 in the filling docking joint group 002 is threadedly connected with the male joint of the mining and conveying drill rod 2 in the filling docking rod group 001, and the drill rod limit block 11 is inserted into the limit groove to fix the position between the pipeline docking block 14 and the drill rod limit block 11.

[0028] When conveying the gangue paste and gel material, a corresponding number of filling pipes can be selected according to different proportions to pump the filling materials. After being pumped, the gangue paste and gel material will enter the rotating hollow drill bit 16 for mixing, and will be discharged through the discharge through hole 20 to fill the underground holes. The filling material discharged through the discharge through hole 20 can also achieve the effect of mixing under the rotation of the alloy head 19. Even after the work is completed, there is no need to extract the filling pipeline. The rotation of the hollow drill bit 16 can be accelerated by the mining drilling equipment, and the mixed filling material in the mixing area can be discharged under the action of centrifugal force. By pumping mud through the mining drilling equipment, the pressure near the hollow drill bit 16 is increased, so that the mud is backflowed into the mixing area through the discharge hole 20, and the mixing of the raw materials in the various pipeline docking tubes 15 is prevented. Different from the traditional filling method, the present application can use a steel wire hose or other wear-resistant hose to transport the filling material, which not only has low requirements on the quality of the filling pipeline, but is also easy to carry. During the filling process, there is no need to frequently plug, unplug and clean the filling pipeline, and the filling efficiency and filling safety are high. Even if part of the hole wall collapses during the filling stage, the hole can be expanded by rotating the hollow drill bit 16 to pull out the filling docking joint group 002.

[0029] Embodiment 2. Embodiment 2 of the present application is based on Embodiment 1, and it is supplemented that the double-liquid source filling and mining device of gangue slurry and cementitious material also includes a docking positioning group 003, which is used to limit the position of the filling docking rod group 001 and is also used for disassembly of the mining and conveying drill rod 2. The docking positioning group 003 includes a positioning frame 22, a drill rod positioning part and a casing positioning part. A filling through hole is opened on the positioning frame 22, and the filling docking rod group 001 is located in the filling through hole. The drill rod positioning part is arranged on the positioning frame 22, and there are two casing positioning parts, which are symmetrically arranged for positioning the pipeline protection casing 1.

[0030] Among them, the drill rod positioning part includes an annular positioning tube 23 and an air intake pipe 25. The annular positioning tube 23 is arranged on the positioning frame 22.

The air intake pipe 25 is arranged on the positioning frame 22, and the air intake pipe 25 is connected to the annular positioning tube 23.

[0031] The sleeve positioning part includes a positioning cylinder 26 and a positioning block 27 . The positioning cylinder 26 is installed on one side of the positioning frame 22 . The positioning block 27 is arranged on the output end of the positioning cylinder 26 . A positioning roller is rotatably arranged in the positioning block 27 for clamping the pipeline protection sleeve 1 .

[0032] Specifically, by starting the positioning cylinder 26, the output end of the positioning cylinder 26 can drive the positioning block 27 to move, and the movement of the positioning block 27 can drive the positioning roller to move, so that the positioning roller contacts the surface of the pipeline protection sleeve 1, so that under the rotation of the positioning roller, the pipeline protection sleeve 1 can only move along the filling through hole on the positioning frame 22, and the pipeline protection sleeve 1 will not rotate. At the same time, under the clamping of the positioning roller, the position of the pipeline protection sleeve 1 can be stabilized to prevent the pipeline protection sleeve 1 from vibrating and deviating.

[0033] When disassembling the two filling docking rod groups 001, move the drill rod limit rod 12 into the annular positioning tube 23. Since the pipeline protection casing 1 and the mining and conveying drill rod 2 are rotated, external inflation equipment is required to pressurize the annular positioning tube 23 through the air inlet pipe 25. When the air pressure in the annular positioning tube 23 increases, the positioning rod 24 in the annular positioning tube 23 will move toward the corresponding side of the limit rod 12 to squeeze the limit rod 12, so that the limit rod 12 compresses the limit spring 13 and contacts with the mining and conveying drill rod 2, fixes the position of the mining and conveying drill rod 2, and then drives the mining and conveying drill rod 2 connected thereto to rotate through the mining and conveying equipment, and the mining and conveying drill rod 2 can be disassembled.

[0034] The above-mentioned mining drilling equipment used to drive the filling docking rod group 001 and the filling docking head group 002 to move and provide filling mud is an existing equipment known to technical personnel in this field. The specific equipment can select different models of drilling machines according to the different holes to be drilled. The specific equipment is not the main innovation point of this application, and it can achieve docking with the mining and conveying drill rod 2.

[0035] Embodiment 3: Embodiment 3 of the present application proposes a double-liquid source filling mining method of gangue paste and cementitious material based on Embodiment 1 and Embodiment 2. The specific method is as follows: Pipeline transportation, when transporting the filling pipeline to the underground mining position, select the filling pipeline corresponding to the pipeline docking tube 15, connect one end of the filling pipeline with the pipeline docking tube 15, and then thread the drill drive tube 18 in the filling docking joint group 002 with the male joint of the mining and conveying drill rod 2 in the filling docking rod group 001, insert the drill rod limit block 11 into the limit groove, and then thread the mining and conveying drill rods 2 in multiple filling docking rod groups 001 in sequence through the mining drilling equipment to form a filling device extending to the inside of the borehole. After the filling docking joint group 002 and the filling docking rod group 001 enter the borehole, the filling pipeline driven by the filling docking joint is clamped in the corresponding pipeline placement groove one, pipeline placement groove two and pipeline placement groove three.

[0036] When the pipeline drilling drives the filling joint group 002 and the filling docking rod group 001 to be transported into the borehole through the mining drilling equipment, the positioning cylinder 26 is started, and the output end of the positioning cylinder 26 drives the positioning block 27 to move, so that the positioning roller on the positioning block 27 contacts the pipeline protection casing 1, and then the mining drilling equipment drives the mining and conveying drill rod 2 to rotate, and the rotation of the mining and conveying drill rod 2 drives the drill bit drive pipe 18 to rotate, and the rotation of the drill bit drive pipe 18 drives the hollow drill bit 16 to rotate through the mixing partition 17.

[0037] The pipeline is limited. When the two filling docking rod groups 001 are docked through the mining drilling equipment and the docking positioning group 003, as the male connector and the female connector of the mining and conveying drill rod 2 in the filling docking rod group 001 are threadedly connected, one of the drill rod limit blocks 11 will squeeze the adjacent pipeline limit block, and the inflation slide bar 9 in the pipeline limit block will be inserted into the corresponding limit docking groove.
