Description

Technical Field

[0001] This application relates to the field of mining engineering technology, and in particular to underground multi-layered ore body resource recovery devices and processes. Background Technology

[0002] Currently, the mining and recovery of multi-layered ore bodies typically employs the segmented open field method for ore extraction. Operators divide the ore body into a primary stope and a secondary stope. They first mine the primary stope, leaving the secondary stope as a pillar. Once the adjacent primary stope has been mined, the mine roadway is sealed, and the primary stope is filled with filling pipes. The stable filling material in the primary stope serves as a pillar. Operators then mine the secondary stope, and after mining is completed, the secondary stope is filled.

[0003] Regarding the aforementioned technologies, the inventors believe that the environment inside the stope is relatively complex, and operators cannot control the volume of the filler when filling the stope with the filling pipe, which leads to the overflow of filler in the first-level stope, increasing costs. At the same time, the first-level stope is a closed space, and excessive filler increases the pressure inside the first-level stope, affecting the mine tunnel structure and posing a significant safety hazard. Summary of the Invention

[0004] To improve the safety of underground multi-layered ore body resource recovery, this application provides an underground multi-layered ore body resource recovery device and process.

[0005] Firstly, this application discloses an underground multi-layered ore body resource recovery device.

[0006] An underground multi-layered ore body resource recovery device includes a feed pipe, a connecting plate installed on the feed pipe, a detection pipe installed on the connecting plate, a limiting disc slidably disposed inside the detection pipe, a limiting groove formed on the inner wall of the detection pipe for sliding cooperation with the limiting disc, a first airbag disposed on the side of the limiting disc near the connecting plate, the first airbag being installed on the inner wall of the limiting groove, a plurality of first air holes formed on the limiting disc, a plurality of second air holes formed on the end of the detection pipe near the connecting plate, a first air outlet pipe installed on the first airbag, and a display disc slidably disposed on the end of the first air outlet pipe away from the first airbag.

[0007] By adopting the above technical solution, after the mining is completed, the operator inputs filling material into the mining area through the feed pipe. When the filling material is saturated, it enters the detection pipe and drives the limiting disc to move. The limiting disc moves within the limiting groove, causing the first airbag to be compressed and deformed. This deformation causes the gas inside the first airbag to enter the first vent pipe. The display disc is displaced under the action of the gas in the first vent pipe, allowing the operator to observe the position of the display disc to see if the filling material in the mining area is saturated. This prevents the filling material from overflowing excessively, thus avoiding impacts on the mine tunnel and ore body structure. It also reduces the possibility of safety accidents during the recovery of multi-layered ore bodies underground. The design of the first and second vents facilitates the discharge of gas from the detection pipe, improving the stability of the equipment.

[0008] Preferably, the first vent pipe has a display groove for sliding and engaging with the display disk, and a fluorescent column is fixedly connected to the display disk, with the end of the fluorescent column away from the display disk able to pass through the first vent pipe.

[0009] By adopting the above technical solution, when the mining area is in the ore mining stage, the fluorescent column is used to block the first vent pipe, thereby reducing the possibility of dust and debris from the external environment entering the first vent pipe and affecting the display disc. When the mining area is filled with saturated filling material, the limiting disc moves the display disc through the first airbag, and the display disc moves the fluorescent column out of the first vent pipe, making it easier for operators to observe the movement of the display disc more intuitively. During installation, the display disc moves the fluorescent column out of the first vent pipe. At this time, the first airbag is not fully inflated. The operator presses the fluorescent column to move the display disc, and the display disc inflates the first airbag through the air in the first vent pipe, causing the limiting disc to reset, which is convenient for operators to use.

[0010] Preferably, a discharge pipe is installed on the connecting plate, and a rotating sleeve is provided between the discharge pipe and the feed pipe. One end of the rotating sleeve is sleeved on the feed pipe, and the other end of the rotating sleeve is sleeved on the discharge pipe. A first through hole is opened on the inner end face of the rotating sleeve. A second through hole is opened on the end face of the feed pipe near the discharge pipe, and the second through hole can communicate with the first through hole. A third through hole is opened on the end face of the discharge pipe near the feed pipe, and the third through hole can communicate with the first through hole. A driving component for driving the rotating sleeve to rotate is provided on the connecting plate.

[0011] By adopting the above technical solution, when the stope is saturated with filling material, the operator uses the drive component to drive the rotating sleeve to rotate. The rotation of the rotating sleeve causes the first through hole to separate from the second through hole, and then the first through hole to separate from the third through hole, thereby isolating the feed pipe from the discharge pipe and thus stopping the stope from continuing to fill.

[0012] Preferably, the driving assembly includes a driving gear fixedly sleeved on the rotating sleeve and a driving rack passing through the connecting plate. The driving gear meshes with the driving rack, and the connecting plate is provided with a control component for driving the driving rack to move.

[0013] By adopting the above technical solution, the operator uses the control components to move the drive rack, which in turn drives the drive gear to rotate. The rotation of the drive gear drives the rotating sleeve to rotate, and the rotation of the rotating sleeve isolates the feed pipe from the discharge pipe, making it convenient for the operator to stop the filling material from entering the mining area.

[0014] Preferably, the control component includes a suspension rope fixedly connected to the drive rack, a suspension block fixedly connected to the end of the suspension rope away from the drive rack, a roller rotatably mounted on the connecting plate, the suspension rope being wound around the roller, a sliding groove for sliding cooperation with the suspension block being provided on the connecting plate, and a fixing component for fixing the drive rack being provided on the connecting plate.

[0015] By adopting the above technical solution, the operator can release the fixed state of the drive rack using the fixing component. Then, the suspension block moves under the action of gravity. The movement of the suspension block causes the suspension rope to slide on the roller. The movement of the suspension rope causes the drive rack to move, making it convenient for the operator to drive the rotating sleeve to rotate.

[0016] Preferably, the fixing component includes a fixing block passing through the connecting plate, a fixing spring fixedly connected to the fixing block, a fixing slot for inserting and engaging with the fixing block on the driving rack, a fixing groove for sliding and engaging with the fixing block on the connecting plate, a fixing spring having its end away from the fixing block fixedly connected to the inner end face of the fixing groove, and an adjusting component for driving the fixing block to move on the connecting plate.

[0017] By adopting the above technical solution, the operator can use the adjustment component to move the fixed block away from the fixed slot on the drive rack. At this time, the fixed spring is in a compressed state, and the drive rack moves under the action of the suspension block, which is convenient for the operator to use. The fixed spring is designed to facilitate the insertion of the fixed block into the drive rack.

[0018] Preferably, the adjusting assembly includes an adjusting gear rotatably mounted on the connecting plate and an adjusting rack passing through the connecting plate, the adjusting gear meshing with the adjusting rack, the fixing block having teeth on it meshing with the adjusting gear, and the connecting plate having a transmission assembly for driving the adjusting rack to move.

[0019] By adopting the above technical solution, the operator uses the transmission component to drive the adjusting rack to move, the adjusting rack to drive the adjusting gear to rotate, and the adjusting gear to drive the fixed block to move, thereby facilitating the operator to release the fixed state of the driving rack and making it convenient for the operator to use.

[0020] Preferably, the transmission assembly includes a second airbag fixedly connected to the adjusting rack and a second air outlet pipe fixedly connected to the second airbag. The connecting plate has a transmission groove for sliding cooperation with the adjusting gear. The end of the second airbag away from the adjusting rack is fixedly connected to the inner end face of the transmission groove. The second air outlet pipe is connected to the second airbag and the first airbag.

[0021] By adopting the above technical solution, the operator fills the mining area with raw materials through the feed pipe. When the raw materials are saturated, the raw materials drive the limiting disc to move through the detection pipe. The limiting disc squeezes the first airbag, and the deformation of the first airbag discharges air into the second airbag through the second air outlet pipe. The second airbag is filled with air and expands. The expansion of the second airbag drives the adjusting rack to move, thereby releasing the fixed state of the driving rack. Under the action of the suspension block, the driving rack drives the rotating sleeve to rotate, thereby isolating the feed pipe and the discharge pipe, making it convenient for the operator to stop filling the mining area.

[0022] Preferably, a movable plate is fixedly connected to the drive rack, the movable plate passes through the connecting plate, the connecting plate has a drive groove for sliding cooperation with the drive rack, the inner side wall of the drive groove has a movable groove for sliding cooperation with the movable plate, the movable groove is connected to the outer side wall of the connecting plate, and the fixed block has an inclined surface at the end near the drive rack.

[0023] By adopting the above technical solution, when installing the connecting plate, the operator drives the moving plate to move the driving rack. When the driving rack moves to the position of the fixed block, the driving rack slides on the inclined surface of the fixed block. Under the action of the inclined surface, the fixed block enters the fixed groove. At this time, the fixing spring is in a compressed state. The operator continues to move the driving rack, and the fixed block slides on the side wall of the driving rack. When the fixed block moves to the position of the fixed slot, the fixed block enters the fixed slot under the action of the fixing spring, thereby fixing the driving rack, which is convenient for the operator to install and use.

[0024] Secondly, this application discloses a process for recovering resources from underground multi-layered ore bodies.

[0025] The underground multi-layered ore body resource recovery process, which utilizes an underground multi-layered ore body resource recovery device, includes the following steps: S1. Mining Preparation: Excavating rock drilling tunnels in the ore body using mechanical equipment; S2. First-Stage Mining: Mining ore resources in the first-stage mining area using mechanical equipment; S3. Filling the First-Stage Mining Area: Driving the moving plate to insert the fixed block into the driving rack, filling the first-stage mining area with cemented raw materials through the feed pipe. When the first-stage mining area is full, the fluorescent column extends out of the first vent pipe, and the rotating sleeve isolates the feed pipe from the vent pipe, terminating the filling of cemented raw materials; S4. Second-Stage Mining: Mining ore resources in the second-stage mining area using mechanical equipment; S5. Filling the Second-Stage Mining Area: Driving the moving plate to insert the fixed block into the driving rack, filling the second-stage mining area with tailings raw materials through the feed pipe. When the second-stage mining area is full, the fluorescent column extends out of the first vent pipe, and the rotating sleeve terminates the filling of tailings raw materials.

[0026] By adopting the above technical solution, operators use mechanical equipment to excavate drilling tunnels in the ore body to facilitate the mining of inter-section stopes. Then, the operator drives a moving plate to insert a fixed block into the drive rack, connecting the feed pipe and the discharge pipe. The operator then uses the feed pipe to fill the first-stage stope with cementing material. When the first-stage stope is full, the cementing material moves a limiting disc, which, through a first airbag, causes a fluorescent column to extend out of the first air outlet pipe for easy observation by the operator. The first airbag moves the fixed block away from the drive rack, causing the drive rack to rotate under the action of the suspended weight, thus connecting the first through hole with the second... The two through holes are separated, thus stopping the continued filling of cementing raw materials. After the second-stage mining area is completed, the operator drives the rotating sleeve to rotate via the moving plate, connecting the feed pipe and the discharge pipe. The operator fills the second-stage mining area with tailings raw materials through the feed pipe. After the second-stage mining area is filled, the tailings raw materials drive the limiting disc to move. The limiting disc, through the first airbag, causes the fluorescent column to extend out of the first air outlet pipe. The limiting disc, through the first airbag, causes the rotating sleeve to rotate, thus stopping the filling of tailings raw materials into the second-stage mining area. This prevents the filler from overflowing and affecting the mine roadway, improving the safety of resource recovery of multi-layered ore bodies underground.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. After the mining is completed, the operator inputs filling material into the stope through the feed pipe. When the filling material is saturated, it enters the detection pipe and drives the limiting disc to move. The limiting disc moves in the limiting groove, causing the first airbag to be compressed and deformed. The compression and deformation of the first airbag causes the gas inside the first airbag to enter the first vent pipe. The display disc is displaced under the action of the gas in the first vent pipe, so that the operator can observe the position of the display disc to see that the filling material in the stope is saturated. This prevents the filling material from overflowing excessively, which could affect the mine tunnel and ore body structure. It also reduces the possibility of safety accidents during the recovery of multi-layered ore bodies underground. The setting of the first and second vents facilitates the discharge of gas from the detection pipe and improves the stability of the equipment. 2. The operator fills the mining area with raw materials through the feed pipe. When the raw materials are saturated, the raw materials drive the limiting disc to move through the detection pipe. The limiting disc squeezes the first air bladder. The deformation of the first air bladder discharges air into the second air bladder through the second air outlet pipe. The second air bladder is filled with air and expands. The expansion of the second air bladder drives the adjusting rack to move, thereby releasing the fixed state of the driving rack. Under the action of the suspension block, the driving rack drives the rotating sleeve to rotate, thereby isolating the feed pipe and the discharge pipe, making it convenient for the operator to stop filling the mining area. 3. Operators use mechanical equipment to excavate drilling tunnels in the ore body to facilitate the mining of stopes between sections. Next, the operator drives a moving plate to insert a fixed block into the drive rack, connecting the feed pipe and the discharge pipe. Then, the operator uses the feed pipe to fill the first stope with cementing material. When the first stope is full, the cementing material moves a limiting disc, which, through a first airbag, extends a fluorescent column out of the first air outlet pipe for easy observation by the operator. The first airbag moves the fixed block away from the drive rack, causing the drive rack to rotate under the action of the suspended weight, thus opening the first through hole and the second through hole. The process begins by opening the feed pipe, thus stopping the continued filling of cementing material. After the second-stage mining area is completed, the operator moves the rotating sleeve via a moving plate, connecting the feed pipe and discharge pipe. The operator then fills the second-stage mining area with tailings material through the feed pipe. Once the second-stage mining area is full, the tailings material moves the limiting disc, which, through the first airbag, causes the fluorescent column to extend out of the first air outlet pipe. The limiting disc, through the first airbag, causes the rotating sleeve to rotate, thus stopping the filling of tailings material into the second-stage mining area. This prevents the overflow of the filler material from affecting the mine roadway and improves the safety of resource recovery from multi-layered ore bodies underground. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] This application discloses an underground multi-layered ore body resource recovery device.

[0036] Reference Figure 1 The ore body resource recovery device includes a feed pipe 1 and a discharge pipe 16. The feed pipe 1 is a circular tube and is horizontally arranged. A connecting plate 11 is provided on the feed pipe 1. The connecting plate 11 is a rectangular plate and is vertically arranged. The connecting plate 11 is sleeved on the feed pipe 1 and is fixedly connected to the feed pipe 1.

[0037] Reference Figure 1 The discharge pipe 16 is a circular tube, horizontally arranged, and passes through the side of the connecting plate 11 away from the feed pipe 1. The discharge pipe 16 is fixedly connected to the connecting plate 11. A detection pipe 12 is provided on the connecting plate 11, vertically arranged, and fixedly connected to the bottom surface of the connecting plate 11.

[0038] Reference Figure 1 , Figure 2 A limiting disc 13 is provided on the inner wall of the probe tube 12. The limiting disc 13 is horizontally positioned, and a limiting groove 121 is formed on the inner wall of the probe tube 12. The outer circumferential surface of the limiting disc 13 slides and engages with the inner wall of the limiting groove 121. A first airbag 14 is provided on the side of the limiting disc 13 near the connecting plate 11. The first airbag 14 is circular and horizontally positioned, and is fixedly connected to the inner wall of the limiting groove 121.

[0039] Reference Figure 2 The outer circumferential surface of the probe tube 12 near the end of the connecting plate 11 has multiple first air holes 131 and the limiting disc 13 has multiple second air holes 122. The arrangement of the first air holes 131 and the second air holes 122 facilitates the discharge of gas from the probe tube 12 and improves the stability of the equipment.

[0040] Reference Figure 2 , Figure 3 A first air outlet pipe 15 is installed on the first airbag 14. The inner wall of the first air outlet pipe 15 is connected to the inner wall of the first airbag 14.

The display disk 151 is positioned on the first air outlet pipe 15 and is horizontally arranged. The display disk 151 is slidably disposed on the inner wall of the first air outlet pipe 15. A display groove 152 is formed on the inner wall of the first air outlet pipe 15, and the inner side wall of the display groove 152 slides and engages with the outer peripheral surface of the display disk 151. The arrangement of the first air hole 131 and the second air hole 122 facilitates the discharge of gas from the detection pipe 12 and improves the stability of the device.

[0041] Reference Figure 3 , Figure 4 A fluorescent column 153 is provided on the display disk 151. The fluorescent column 153 is vertically arranged and fixedly connected to the display disk 151. There is a gap between the outer peripheral surface of the fluorescent column 153 and the inner side wall of the first gas outlet pipe 15. The fluorescent column 153 can extend out of the end of the first gas outlet pipe 15 away from the detector tube 12.

[0042] When the stope is saturated with filling material, the filling material moves the limiting disc 13. The limiting disc 13 moves the display disc 151 through the first airbag 14. The display disc 151 moves the fluorescent column 153 out of the first air outlet pipe 15, so that the workers can judge that the filling material in the stope is saturated by the fluorescent column 153, so that the operators can stop filling. The filling material will not overflow excessively, and will not affect the mine tunnel and ore body structure, thus reducing the possibility of safety accidents during the recovery of multi-layered ore body resources underground.

[0043] Referring to the figure, a rotating sleeve 17 is provided between the feed pipe 1 and the discharge pipe 16.

[0045] Reference Figure 3 A movable plate 23 is provided on the drive rack 22. The movable plate 23 is horizontally arranged and passes through the connecting plate 11. A movable slide groove 25 is provided on the inner wall of the drive slide groove 24. The outer wall of the connecting plate 11 slides and engages with the inner wall of the movable slide groove 25.

[0046] Reference Figure 3 The connecting plate 11 is equipped with a control component 3 for driving the drive rack 22 to move.

[0047] Reference Figure 3 , Figure 5 The connecting plate 11 is provided with a fixing component 4 for fixing the drive rack 22. The fixing component 4 includes a fixing block 41 and a fixing spring 42. The fixing block 41 is horizontally arranged and passes through the connecting plate 11. The drive rack 22 is provided with a fixing slot 43 for inserting and cooperating with the fixing block 41. The end of the fixing block 41 that is inserted into the fixing slot 43 is provided with a bevel.

[0048] Reference Figure 5 A fixing groove 44 is provided on the connecting plate 11, and the inner side wall of the fixing groove 44 slides and engages with the outer side wall of the fixing block 41. The fixing spring 42 is horizontally set and fixedly connected to the fixing block 41. The end of the fixing spring 42 away from the fixing block 41 is fixedly connected to the inner end face of the fixing groove 44. When the operator moves the moving plate 23, the moving rod drives the driving rack 22 to move. The movement of the driving rack 22 causes the fixing block 41 to move under the action of the inclined plane. At this time, the fixing spring 42 is in a compressed state. The operator continues to move the moving plate 23, causing the fixing block 41 to slide on the side wall of the driving rack 22. When the fixing block 41 moves to the position of the fixing slot 43, the fixing block 41 is inserted into the fixing slot 43 under the action of the fixing spring 42, which facilitates the operator to install and use the equipment.

[0049] Reference Figure 5 The connecting plate 11 is provided with an adjusting assembly 5 for driving the fixed block 41 to move. The adjusting assembly 5 includes an adjusting gear 51 and an adjusting rack 52. The adjusting gear 51 is vertically arranged and disposed inside the connecting plate 11. The adjusting gear 51 is rotatably mounted on the connecting plate 11. The fixed block 41 is provided with teeth, and the teeth on the fixed block 41 mesh with the adjusting gear 51. The adjusting rack 52 is horizontally arranged and passes through the connecting plate 11. The adjusting rack 52 meshes with the adjusting gear 51.

[0050] Reference Figure 5 The connecting plate 11 is provided with a transmission assembly 6 for driving the adjustment rack 52 to move. The transmission assembly 6 includes a second airbag 61 and a second air outlet pipe 62. The second airbag 61 is cylindrical and horizontally arranged. The second airbag 61 is fixedly connected to the adjustment rack 52. The connecting plate 11 is provided with a transmission groove 63. The inner wall of the transmission groove 63 slides and engages with the outer wall of the adjustment rack 52. The second airbag 61 is fixedly connected to the inner end face of the transmission groove 63.

[0051] Reference Figure 3 , Figure 5 The second air outlet pipe 62 is installed on the first airbag 14. The inner wall of the second air outlet pipe 62 is connected to the inner wall of the first airbag 14. The end of the second air outlet pipe 62 away from the first airbag 14 is fixedly connected to the second airbag 61. The inner wall of the second air outlet pipe 62 is connected to the inner wall of the second airbag 61.

[0052] When the stope is saturated with filling material, the filling material drives the limiting disc 13 to move. The limiting disc 13 drives the second airbag 61 to expand and deform through the first airbag 14. The deformation of the second airbag 61 drives the adjusting rack 52 to move. The adjusting rack 52 drives the fixed block 41 to move through the adjusting gear 51. The movement of the fixed block 41 causes the driving rack 22 to be unlocked. The driving rack 22 moves under the action of the suspension block 32, driving the driving crown gear to rotate. The rotation of the driving gear 21 causes the first through hole 171 and the second through hole 172 to separate, thereby isolating the feed pipe 1 and the discharge pipe 16 and preventing the filling material from entering the stope.

[0053] The implementation principle of the underground multi-layer ore body resource recovery device in this application embodiment is as follows: the operator moves the moving plate 23 to drive the rotating sleeve 17 to rotate, so that the first through hole 171 is connected to the second through hole 172 and the third through hole 173. Then the operator presses the fluorescent column 153 into the first gas outlet pipe 15 to reset the limiting disc 13.

[0054] When the stope is saturated with filling material, the fluorescent column 153 extends under the action of the limiting disc 13, making it convenient for operators to observe the filling status in the stope. The limiting disc 13 drives the fixed block 41 to move and release the lock of the drive rack 22. The drive rack 22 drives the rotating sleeve 17 to rotate, causing the first through hole 171 to separate and misalign with the second through hole 172 and the third through hole 173, thereby preventing the filling material from entering the stope and preventing the filling material from overflowing excessively, thus affecting the mine roadway and ore body structure and reducing the possibility of safety accidents during the recovery of multi-layered ore body resources underground.

[0055] This application also discloses an underground multi-layered ore body resource recovery process, which utilizes an underground multi-layered ore body resource recovery device.

[0056] Reference Figure 1-5 The mining process for layered, fractured, gently dipping iron ore deposits includes the following steps: S1. Mining preparation: Operators use mechanical equipment to excavate rock drilling tunnels in the ore body in order to mine the mining areas between sections; S2, One-step mining: Mining ore resources in a one-step mining area using mechanical equipment; S3, Filling the first-stage stope: The operator drives the moving plate 23 to insert the fixed block 41 into the driving rack 22, so that the feed pipe 1 and the discharge pipe 16 are connected. Then, the operator uses the feed pipe 1 to fill the first-stage stope with cementing material. When the first-stage stope is full, the cementing material drives the limiting disc 13 to move. The limiting disc 13 drives the fluorescent column 153 to extend out of the first air outlet pipe 15 through the first air bag 14, so that the operator can observe it. The first air bag 14 drives the fixed block 41 to move away from the driving rack 22, so that the driving rack 22 drives the rotating sleeve 17 to rotate under the action of the suspension block 32. The first through hole 171 and the second through hole 172 are separated, thereby terminating the filling of cementing material. S4. Two-step mining: Mining ore resources in two-step mining areas using mechanical equipment; S5. Filling the Second-Step Mining Area: The operator drives the rotating sleeve 17 to rotate via the moving plate 23, connecting the feed pipe 1 and the discharge pipe 16. The operator fills the second-step mining area with tailings material through the feed pipe 1. After the second-step mining area is filled, the tailings material drives the limiting disc 13 to move. The limiting disc 13 causes the fluorescent column 153 to extend out of the first air outlet pipe 15 through the first airbag 14. The limiting disc 13 causes the rotating sleeve 17 to rotate through the first airbag 14, thereby stopping the filling of tailings material into the second-step mining area, thus preventing the overflow of the filler material from affecting the mine roadway and improving the safety of resource recovery of multi-layered ore bodies underground.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
