Description

Technical Field

[0001] This invention relates to the field of tungsten ore residue mining technology, and more particularly to a room-and-pillar mining method applicable to tungsten ore residue mining. Background Technology

[0002] When mining tungsten ore residue, room-and-pillar mining is generally used. Room-and-pillar mining equipment includes top space protection equipment, cutting equipment, transportation equipment, blasting equipment, etc. In order to ensure the efficiency of tungsten ore residue mining, the upper remaining goaf area is generally used as the top space for mining, which makes top space protection equipment important.

[0003] Existing top space protection equipment typically uses a combination of anchor nets and anchor bolts. The anchor nets provide top protection, while the anchor bolts provide connection and reinforcement. However, during use, as falling objects land on the anchor nets, they tend to move towards the center of the nets, resulting in significant pressure on the center. This makes the anchor nets vulnerable after long-term use, greatly reducing their lifespan and requiring regular replacement. If replacement is not done in a timely manner, the anchor nets will be directly damaged, rendering the top space protection equipment ineffective. Falling objects will then impact the mining space below, reducing the usability of the room-and-pillar mining equipment. Summary of the Invention

[0004] This invention discloses a room-and-pillar mining apparatus applicable to the mining of tungsten ore residue, aiming to solve the technical problem that the top space protection equipment in the room-and-pillar mining apparatus is easily damaged during the protection process, causing it to lose its corresponding protective effect and resulting in the destruction of the mining space below.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A room-and-pillar mining device suitable for tungsten ore residual mining includes two triangular mounting frames. A common anchor mesh is provided on opposite sides of the two triangular mounting frames, and a falling object transfer assembly is located in the upper space at both ends of the anchor mesh. The falling object transfer assembly includes a load-bearing frame and a mounting plate. The mounting plate is fixedly connected to the outside of the load-bearing frame. A guide plate is fixedly connected to the bottom side of the load-bearing frame, and the guide plate contacts the anchor mesh. Embedded reinforcing plates are fixedly connected at equal intervals on the side of the mounting plate away from the anchor mesh. Each embedded reinforcing plate has a pressing plate connected to both sides via hinges. The pressing plates and the embedded reinforcing plates are equidistant on opposite sides. A compression spring rod is fixedly connected at a distance. Protective telescopic belts are fixedly connected to the outer sides of the upper and lower ends of the compression spring rod, and the other ends of the protective telescopic belts are located on the outer side of the compression plate. Accumulating embedded pieces are fixedly connected at equal distances to the outer side of the compression plate away from the embedded reinforcing plate. A motor box is fixedly connected to the outer side of the load-bearing frame, and a drive motor is fixedly connected inside the motor box. The output shaft of the drive motor is fixedly connected to a rotating shaft through a coupling. The other end of the rotating shaft is connected to the inner wall of one side of the load-bearing frame through a bearing. Rotating blades are distributed in a ring on the outer side of the rotating shaft. A triangular protective frame is fixedly connected to the inner side of the load-bearing frame above the rotating blades.

[0007] By incorporating a falling object transfer component, this protective device is installed in the upper space. When a falling object enters the anchor net, it slides down to both sides. Under the action of the guide plates, the object is guided into the load-bearing frame. The drive motor is then activated, causing the rotating blades on the shaft to rotate rapidly, thus flipping the object to the inside of the load-bearing frame away from the guide plates. This achieves the transfer of the falling object. The falling object transfer component does not contact the anchor net, and the combined weight of the load-bearing frame and the falling object inside it will not cause any compression damage to the anchor net. This ensures that the anchor net can be used for a long time without the need for periodic replacement, ensuring that the anchor net is always in a protective state.

[0008] In a preferred embodiment, the tops of the two triangular mounting brackets are fixedly connected to the same hanging plate, and the tops of the hanging plate are fixedly connected to anchor rods at equal intervals.

[0009] In a preferred embodiment, the top of the mounting plate is provided with an adjustable reinforcement component, which includes a top plate and a connecting steel wire rope. The top plate is fixedly connected to the top of the mounting plate, and telescopic connecting rods are fixedly connected at equal intervals on the top of the top plate. The tops of multiple telescopic connecting rods are fixedly connected to the same lifting frame. The outer side of the lifting frame has perforations at equal intervals, and a second pile is inserted into the interior of each perforation. One end of the connecting steel wire rope is located on the outer side of the lifting frame, and the other end of the connecting steel wire rope is located on the bottom inner wall of the load-bearing frame.

[0010] After the installation of the falling object transfer component, which is equipped with adjustable reinforcement components, the lifting frame is moved according to the actual height of the goaf. During the lifting frame's ascent, the telescopic connecting rod extends accordingly, and then the No. 2 pile is driven into the ore in the goaf. The steel wire rope is connected to the lifting frame and the load-bearing frame. The load-bearing frame is supported by the adjustable reinforcement components to ensure that it will not fall off when the load-bearing frame is filled with a large amount of falling objects.

[0011] In a preferred embodiment, the telescopic connecting rod includes an outer adjusting cylinder and an inner adjusting rod. The inner adjusting rod is slidably connected to the inside of the outer adjusting cylinder. The outer side of multiple telescopic connecting rods is fixedly connected to the same outer integrating plate. The outer integrating plate is located outside the outer adjusting cylinder. Inclined friction plates are fixedly connected at equal distances to the outer side of the outer integrating plate away from the connecting wire rope. The end of the inclined friction plate away from the outer integrating plate points upward.

[0012] In a preferred embodiment, an auxiliary flow guiding component is provided below the triangular mounting frame, and the auxiliary flow guiding component includes a guide rail, which is fixedly connected to the bottom of the triangular mounting frame. A movable block is slidably connected to the inner wall of the guide rail, and a fixed block is fixedly connected to the outer side of the guide rail near the top. A hydraulic cylinder is fixedly connected to the side of the fixed block facing the movable block, and the output end of the hydraulic cylinder is fixedly connected to the outer side of the movable block. The bottom of two movable blocks located on the same side is fixedly connected to the same movable connecting plate, and connecting spring rods are fixedly connected at equal intervals to the top of the movable connecting plate. The other end of the multiple connecting spring rods is fixedly connected to the same semi-circular push column, which is in contact with the anchor mesh.

[0013] With the auxiliary flow guiding component, when a falling object lands above the anchor net, the hydraulic cylinder is adjusted to drive the moving block to slide inside the guide rail. The semi-circular push columns on each connecting spring rod then vibrate and push the falling object above the anchor net, accelerating the falling object from the anchor net to the load-bearing frame. The auxiliary flow guiding component accelerates the separation of the falling object from the anchor net, further reducing the squeezing damage to the anchor net and protecting it.

[0014] In a preferred embodiment, the bottom of the triangular mounting bracket is fixedly connected to a connecting frame, and the outer side of the connecting frame is provided with mounting holes at equal intervals, with a No. 1 pile inserted into the inner wall of each mounting hole.

[0015] A method for using a room-and-pillar mining apparatus suitable for tungsten ore residual mining, applied to the aforementioned room-and-pillar mining apparatus suitable for tungsten ore residual mining, the method comprising the following steps:

[0016] S1: After the anchor net is installed, the falling object transfer component is installed. After its installation, the lifting frame is moved according to the actual height of the goaf. During the lifting frame's ascent, the telescopic connecting rod extends accordingly, and then the No. 2 pile is driven into the ore in the goaf. The steel wire rope is then connected to achieve the connection between the lifting frame and the load-bearing frame.

[0017] S2: During the operation of the protective equipment, when a falling object lands above the anchor net, the adjusting hydraulic cylinder drives the moving block to slide inside the guide rail. The semi-circular push column on each connecting spring rod then vibrates and pushes the falling object above the anchor net, accelerating the movement of the falling object from the anchor net to the load-bearing frame.

[0018] S3: Start the drive motor. The drive motor drives each flipping blade on the rotating shaft to rotate rapidly, thereby flipping the falling object to the inside of the load-bearing frame away from the guide plate, thus realizing the transfer of the falling object.

[0019] As can be seen from the above, the room-and-pillar mining device for tungsten ore residual mining provided by the present invention has the following technical effects: when a falling object falls into the anchor net, the falling object in the anchor net slides to both sides. Under the action of the guide plate, the falling object is guided into the load-bearing frame. The drive motor is started, and the drive motor drives the various flipping blades on the rotating shaft to rotate rapidly, thereby flipping the falling object to the inner side of the load-bearing frame away from the guide plate, thus realizing the transfer of the falling object. The falling object transfer component is in a non-contact state with the anchor net. The combined weight of the load-bearing frame and the falling object inside it will not cause any squeezing damage to the anchor net, thereby ensuring that the anchor net can be used for a long time without the need for periodic replacement, and ensuring that the anchor net is always in a protective state.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] The room-and-pillar mining device disclosed in this invention, suitable for the mining of tungsten ore residue, is mainly used in scenarios where the space above the mining space is compressed by falling objects at the center of the anchor net, making it vulnerable to damage after long-term use. Infrequent replacement can easily lead to safety accidents due to damage to the anchor net.

[0030] Reference Figure 1-7This is a room-and-pillar mining device suitable for tungsten ore residual mining. It includes two triangular mounting frames 1, with a common anchor mesh 7 on opposite sides of each frame. A falling object transfer assembly 4 is located in the upper space at both ends of the anchor mesh 7. The falling object transfer assembly 4 includes a load-bearing frame 401 and a mounting plate 402. The mounting plate 402 is fixedly connected to the outside of the load-bearing frame 401. A guide plate 406 is fixedly connected to the bottom side of the load-bearing frame 401, contacting the anchor mesh 7. Embedded reinforcing plates 403 are fixedly connected at equal intervals on the side of the mounting plate 402 away from the anchor mesh 7. Each embedded reinforcing plate 403 has a pressing plate 404 connected to both sides via hinges. A pressing spring is fixedly connected at equal intervals to the opposite side of the pressing plate 404 and the embedded reinforcing plate 403. The rod 411 and the embedded reinforcing plate 403 are both fixedly connected to the outer sides of the upper and lower ends of the compression spring rod 411 with protective telescopic belts 413. The other end of the protective telescopic belts 413 is located on the outer side of the compression plate 404. The compression plate 404 is fixedly connected to the outer side of the embedded reinforcing plate 403 at equal distances. The outer side of the load-bearing frame 401 is fixedly connected to the motor box 409, and the inside of the motor box 409 is fixedly connected to the drive motor 410. The output shaft of the drive motor 410 is fixedly connected to the rotating shaft 408 through a coupling. The other end of the rotating shaft 408 is connected to the inner wall of one side of the load-bearing frame 401 through a bearing. The outer side of the rotating shaft 408 is circumferentially distributed with rotating blades 407. The inner side of the load-bearing frame 401 above the rotating blades 407 is fixedly connected to the triangular protective frame 405.

[0031] Specifically, during the installation of the falling object transfer component 4, multiple embedding slots are opened inside the goaf above the No. 1 pile body 6. Then, the embedding reinforcement plate 403 is pressed into the embedding slot. During the pressing process, the compression spring rod 411 is compressed, and the compression plate 404 is in close contact with the embedding slot, thereby improving the stability of the falling object transfer component 4 installation.

[0032] In specific application scenarios, each of the stacking insert pieces 412 on the outer side of the extrusion plate 404 is pressed into the ore on the outer side of the insert groove, increasing the contact area between the ore and the falling object transfer component 4, thereby further increasing the strength of the connection between the two.

[0033] It should be noted that after the protective device is installed in the upper space, when a falling object enters the anchor net 7, the falling object slides to both sides of the anchor net 7. Under the action of the guide plate 406, the falling object is guided into the load-bearing frame 401. The drive motor 410 is started, and the drive motor 410 drives the various flipping blades 407 on the rotating shaft 408 to rotate rapidly, thereby flipping the falling object to the inside of the load-bearing frame 401 away from the guide plate 406, thus realizing the transfer of the falling object. The falling object transfer component 4 is in a non-contact state with the anchor net 7. The combined weight of the load-bearing frame 401 and the falling object inside it will not cause any squeezing damage to the anchor net 7, thus ensuring that the anchor net 7 can be used for a long time without the need for periodic replacement, ensuring that the anchor net 7 is always in a protective state.

[0034] Reference Figure 1 and Figure 2 In a preferred embodiment, the tops of the two triangular mounting brackets 1 are fixedly connected to the same hanging plate 2, and the tops of the hanging plate 2 are fixedly connected to anchor rods 3 at equal intervals.

[0035] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 In a preferred embodiment, the top of the mounting plate 402 is provided with an adjustable reinforcement component 9, which includes a top plate 902 and a connecting wire rope 901. The top plate 902 is fixedly connected to the top of the mounting plate 402, and telescopic connecting rods 907 are fixedly connected at equal intervals on the top of the top plate 902. The tops of multiple telescopic connecting rods 907 are fixedly connected to the same lifting frame 905. The outer side of the lifting frame 905 has through holes at equal intervals, and a second pile 903 is inserted into the inside of each through hole. One end of the connecting wire rope 901 is located on the outer side of the lifting frame 905, and the other end of the connecting wire rope 901 is located on the bottom inner wall of the load-bearing frame 401.

[0036] In a preferred embodiment, the telescopic connecting rod 907 includes an outer adjusting cylinder and an inner adjusting rod. The inner adjusting rod is slidably connected to the inside of the outer adjusting cylinder. The outer sides of multiple telescopic connecting rods 907 are fixedly connected to the same outer integrating plate 906. The outer integrating plate 906 is located outside the outer adjusting cylinder. Inclined friction plates 904 are fixedly connected at equal distances to the outer side of the outer integrating plate 906 away from the connecting wire rope 901. The end of the inclined friction plate 904 away from the outer integrating plate 906 points upward.

[0037] Specifically, the contact friction between the protective equipment and the goaf is increased by tilting the friction plate 904, thereby improving the stability of the protective equipment installation.

[0038] In specific application scenarios, when the lifting frame 905 moves to the designated point, if the load-bearing frame 401 needs to be slightly adjusted due to excessive gravity during the use of the protective equipment, the contact friction plates will be stuck in the ore gaps in the goaf area when the lifting frame 905 rises, thus buffering the downward adjustment of the load-bearing frame 401 and stopping its downward trend.

[0039] It should be noted that after the falling object transfer component 4 is installed, the lifting frame 905 is moved according to the actual height of the goaf. During the upward movement of the lifting frame 905, the telescopic connecting rod 907 extends accordingly, and then the second pile 903 is driven into the ore in the goaf. The connecting wire rope 901 connects the lifting frame 905 to the load-bearing frame 401. The load-bearing frame 401 is supported by the adjustable reinforcement component 9 to ensure that the load-bearing frame 401 will not fall off when it is filled with a large amount of falling objects.

[0040] Reference Figure 1 , Figure 2 and Figure 7 In a preferred embodiment, an auxiliary flow guiding component 8 is provided below the triangular mounting frame 1, and the auxiliary flow guiding component 8 includes a guide rail 801. The guide rail 801 is fixedly connected to the bottom of the triangular mounting frame 1. A moving block 802 is slidably connected to the inner wall of the guide rail 801, and a fixing block 803 is fixedly connected to the outer side of the guide rail 801 near the top. A hydraulic cylinder 805 is fixedly connected to the side of the fixing block 803 facing the moving block 802. The output end of the hydraulic cylinder 805 is fixedly connected to the outer side of the moving block 802. The bottom of the two moving blocks 802 located on the same side is fixedly connected to the same moving connecting plate 807. A connecting spring rod 804 is fixedly connected at equal distances to the top of the moving connecting plate 807. The other end of the multiple connecting spring rods 804 is fixedly connected to the same semi-circular push column 806. The semi-circular push column 806 is in contact with the anchor net 7.

[0041] It should be noted that when the falling object lands on the anchor net 7, the adjusting hydraulic cylinder 805 drives the moving block 802 to slide inside the guide rail 801. The semi-circular push column 806 on each connecting spring rod 804 then vibrates and pushes the falling object above the anchor net 7, accelerating the movement of the falling object from the anchor net 7 into the load-bearing frame 401. The auxiliary flow guiding component 8 accelerates the separation of the falling object from the anchor net 7, further reducing the squeezing damage to the anchor net 7 and protecting the anchor net 7.

[0042] Reference Figure 1 and Figure 2 In a preferred embodiment, a connecting frame 5 is fixedly connected to the bottom of the triangular mounting bracket 1, and mounting holes are opened at equal intervals on the outer side of the connecting frame 5, with a No. 1 pile body 6 inserted into the inner wall of each mounting hole.

[0043] The method of using a room-and-pillar mining apparatus suitable for tungsten ore residual mining, applied to the aforementioned room-and-pillar mining apparatus suitable for tungsten ore residual mining, includes the following steps:

[0044] S1: After the anchor net 7 is installed, the falling object transfer component 4 is installed. After its installation, the lifting frame 905 is moved according to the actual height of the goaf. During the process of the lifting frame 905 rising, the telescopic connecting rod 907 extends accordingly, and then the second pile body 903 is driven into the ore in the goaf. The steel wire rope 901 is connected to realize the connection between the lifting frame 905 and the load-bearing frame 401.

[0045] S2: During the operation of the protective equipment, when a falling object lands on the anchor net 7, the adjusting hydraulic cylinder 805 drives the moving block 802 to slide inside the guide rail 801. Then, the semi-circular push column 806 on each connecting spring rod 804 will vibrate and push the falling object above the anchor net 7, accelerating the falling object to move from the anchor net 7 into the load-bearing frame 401.

[0046] S3: Start the drive motor 410. The drive motor 410 drives each flipping blade 407 on the rotating shaft 408 to rotate rapidly, thereby flipping the falling object to the inside of the load-bearing frame 401 away from the adhering guide plate 406, thereby realizing the transfer of the falling object.

[0047] Working principle: After the anchor net 7 is installed, the falling object transfer component 4 is installed. After its installation, the lifting frame 905 is moved according to the actual height of the goaf. During the ascent of the lifting frame 905, the telescopic connecting rod 907 extends accordingly, thereby driving the second pile 903 into the ore at the goaf. The connecting wire rope 901 connects the lifting frame 905 to the load-bearing frame 401. During the operation of the protective equipment, when a falling object lands above the anchor net 7, the hydraulic cylinder 805 is adjusted to drive the movement. As block 802 slides inside guide rail 801, the semi-circular push column 806 on each connecting spring rod 804 vibrates and pushes the falling object above the anchor net 7, accelerating the falling object from the anchor net 7 to the load-bearing frame 401. After the falling object enters the load-bearing frame 401, the drive motor 410 is started. The drive motor 410 drives each flipping blade 407 on the rotating shaft 408 to rotate rapidly, thereby flipping the falling object to the inside of the load-bearing frame 401 away from the adhering guide plate 406, thus realizing the transfer of the falling object.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

The steel wire rope (901) is connected to realize the connection between the lifting frame (905) and the load-bearing frame (401). S2: During the operation of the protective equipment, when the falling object lands above the anchor net (7), the hydraulic cylinder (805) is adjusted to drive the moving block (802) to slide inside the guide rail (801). Then, the semi-circular push column (806) on each connecting spring rod (804) will oscillate and push the falling object above the anchor net (7), accelerating the falling object to move from the anchor net (7) to the load-bearing frame (401). S3: Start the drive motor (410). The drive motor (410) drives each flipping blade (407) on the rotating shaft (408) to rotate rapidly, thereby flipping the falling object to the inside of the load-bearing frame (401) away from the adhering guide plate (406), thereby realizing the transfer of the falling object.
