Description

Technical Field

[0001] The invention relates to a mining device and a stabilization method thereof, a repositioning method and an anchoring device for sidewall mining, belonging to the technical field of sidewall mining mineral resources. Background Art

[0002] Sidewall mining is a mineral resource mining technology that starts from the exposed edge of a coal seam or vein and is specifically used to mine coal, ore and other resources that are too deep to be suitable for open-pit mining because of the overburden. In this mining method, the cutting mechanism is mounted on an extendable device, allowing the cutting head to penetrate deep into the mine for mining operations, and then the mined material is transported out of the mine through a series of conveyors. As the mine lengthens and the mining speed increases, more force needs to be applied to the cutting mechanism, which requires the sidewall mining equipment to have sufficient stability. The equipment needs to remain stable when pushing in or pulling out the cutting mechanism and conveyor to cope with the increased mass and changes in the vein as the mining depth increases. In addition, safety is also an important consideration, because multiple mines may be cut in parallel and these mines may extend far. If the mining direction is not accurate, it may cause the coal pillar area supporting the mine to become weak, increasing the risk of mine collapse, resulting in equipment damage and production losses. Therefore, in order to ensure the accuracy and safety of mining, the position and direction of the sidewall mining equipment need to be precisely controlled to maintain the accuracy of the mining direction, which further emphasizes the need to improve the stability of the equipment.

DETAILED DESCRIPTION

[0016] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0017] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and the like are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances. Example 1

[0019] See also Figure 1 The present invention introduces an anchoring device for sidewall mining, comprising an anchor body 2, a first power linear motion system 10 and a second power linear motion system 12. One end of the anchor body 2 is provided with a cutting edge 3 for cutting a rich ore vein 4, and the other end is detachably connected to a drill rig 6. The drill rig 6 can be an electric, pneumatic or hydraulic power drill rig. The drill rig 6 is installed on the first power linear motion system 10. The anchor body 2 is also provided with a guide sleeve 8 for maintaining a vertical direction. At least one support member 11 for vertical positioning is also installed between the anchor body 2 and the second power linear motion system 12. The support member 11 can be a jack or a shock absorber. The second power linear motion system 12 drives at least one support member 11 to move up and down. It should be noted that the electric wires or hydraulic pipelines 9 provide power for the drilling rig 6, and the drilling rig 6 also includes a driving device for axially driving the anchor body 2 and a rotating device for axially rotating the anchor body 2 in cooperation with the axial drive, and the driving device is integrated with the rotating device, thereby enabling the anchor body 2 to be effectively inserted into the rich ore vein 4.

[0020] Furthermore, the anchor body 2 is a hollow cylindrical structure. First, when the hollow cylindrical anchor body is driven into the rich ore vein 4, a part of the formation material enters the interior of the anchor body 2, such as rocks, debris 62, mud, etc., so that the anchor body 2 is fixed to the rich ore vein 4. The anchor body 2 filled with formation material has excellent vibration absorption performance. Secondly, due to the larger size and structure of the anchor body 2, the anchor body 2 has a relatively high bending limit. Similarly, when the anchor body 2 is filled with formation material, it shows a higher yield limit. Thirdly, the hollow cylindrical structure is easier to insert into the rich ore vein 4 and easier to remove from the rich ore vein 4, so that it can be quickly positioned and the mining equipment can be quickly disassembled.

[0021] In the embodiment of the present invention, especially when deep anchoring is achieved, the radial thickness of the cutting edge 3 is greater than the radial thickness of the anchor body 2, that is, the thick wall of the cutting edge 3 is greater than the thickness of the anchor body shell 5, and the cutting edge 3 at one end of the anchor body 2 can select a suitable cutting edge 3 according to different geological conditions of the rich ore vein 4, which usually contains hard bottom (such as rock and sandstone) and relatively soft bottom (such as coal and mud). For hard bottom geology, select Figure 4 and Figure 5 A thickened or serrated cutting edge 3 is provided; for soft bottom geology, a thin edge or a sharp cutting edge is selected. At the same time, the replaceability of the cutting edge 3 and the wear resistance of the material are considered to adapt to different mining environments.

[0022] Furthermore, the first powered linear motion system 10 further includes a locking device, which is connected to the anchor body 2 so that the anchor body 2 is kept in a specific position during the drilling process.

[0023] See also Figure 7 The anchoring device 1 also includes a vacuum dust removal system 61, which helps to keep the working environment clean and improve drilling efficiency. The vacuum dust removal system 61 includes a suction nozzle 66 near the cutting edge 3, a flexible transport hose 67, a collection box 63 and a vacuum pump 68. The suction nozzle 66 is connected to the collection box 63 through the flexible transport hose 67. The anchor body 2 transports the fragments 62 generated by inserting into the rich ore vein 4 through the cutting edge 3 to the collection box 63 through the flexible transport hose 67. In order to maintain the vacuum in the vacuum dust removal system 61, one end of the collection box 63 is connected to the vacuum pump 68 through a dust filter 69, thereby protecting the vacuum pump 68 from harmful particles.

[0024] Alternatively, a water pipe 70 is connected to the cutting edge 3, and flowing water is input through the water pipe 70 to mix with soil particles in the rich ore vein 4 to form mud that is easier to transport. The flowing water also helps to cool the cutting edge 3, thereby reducing the risk of overheating caused by long-term drilling, thereby achieving a faster drilling speed. Example 2

[0025] See also Figure 1 , when the anchor device 1 is in the pulled-out (non-working) state, the anchor body 2 is pulled out from the rich ore vein 4, that is, the vertical distance A of the anchor device 1 relative to the rich ore vein 4, and bears and absorbs various vertical loads of the mining equipment, and the support member 11 is in the pulled-up position without contacting the rich ore vein 4; See also Figure 2When the anchor device 1 is in the drilling state, according to the type of the drilling rig 6, with the assistance of the vertical movement of the first power linear motion system 10, the anchor body 2 is driven to the rich ore vein 4 through the cutting edge 3 to rotate around its axis 7. At the same time, the second power linear motion system 12 vertically positions the support member 11 and drives the guide sleeve 8 for maintaining the vertical direction to move, so as to accurately vertically position the anchor device 1, that is, the vertical distance B of the anchor device 1 relative to the rich ore vein 4.

[0026] Furthermore, the anchor body can be cut, with the plane area 15 of the rich ore vein 4 as a reference, to release the anchor device 1 and leave a portion of the anchor body 2 in the rich ore vein 4. In the actual sidewall mining process, the anchor body 2 is usually cut along the plane area 15 to ensure that the portion stuck on the rich ore vein 4 does not hinder the movement of the vehicle. Example 3

[0027] Figure 3 Another second anchor body 20 is shown, one end of which is detachably connected to a second cutting edge 21, and the other end has a connecting shape 22 connected to a second drilling rig (the same as the drilling rig in Figure 1). The second anchor body 20 rotates around its second axis 23, and the radial thickness C of the wall (cylinder wall 24) of the second anchor body 20 is smaller than the radial thickness D of the second cutting edge 21, so that the second anchor body 20 can be more easily inserted into the rich ore vein 4 in the direction of the second cutting edge 21.

[0028] Figure 4 Another third anchor 30 is shown, which has a different Figure 1-Figure 3 The third cutting edge 31, with Figure 3 In contrast, the cutting edge 31 has a greater axial thickness than the third anchor shell 32. The third anchor 30 also has a weakened radial region 33, which makes it easier to cut the anchor and can quickly cut off the weakened region, for example Figure 1 and Figure 2 transfer Figure 4 The third cutting edge 31 in the sidewall can easily cut off the plane area 15. In the sidewall mining process, the geological conditions of hard bottom (such as rock and sandstone) are usually encountered, and the third cutting edge 31 is used.

[0029] Figure 5 Another fourth anchor body 40 is shown, which has a serrated fourth cutting edge 41. The fourth anchor body 40 is rotated about its fourth axis 42 by the fourth cutting edge 41, and is axially driven to the rich mineral vein 4 in the direction of the fourth cutting edge 41. Example 4

[0030] See also Figure 6 The present invention introduces a mining device, Figure 1 and Figure 2 Taking the anchoring device 1 described above as an example, the mining equipment 50 includes a conveying section group 56 and a connecting device integrated with the mining equipment 50. The mining equipment 50 is connected to multiple anchoring devices 1 through the connecting device. Each anchoring device 1 is provided with an anchor body 2, the anchor body 2 is partially inserted into the ground, and the support member 11 is supported above the rich ore vein to be mined. Each drilled anchoring device is in Figure 2 Status shown.

[0031] In order to stabilize the mining equipment 50 through the anchoring device 1, thereby maintaining the orientation of the mining equipment 50 relative to the mined side wall 54, the anchor body 2 drills into the rich ore vein 4 along a preset direction (optimal drilling path) through the cutting edge 3, and transports the mineral resources mined from the rich ore vein 4 to the ground through the conveying section group 56.

[0032] Furthermore, the connection device may be a crossbeam structure or a clamp, and the mining equipment 50 is screwed to the plurality of anchoring devices 1 via the crossbeam 13 . Example 5

Example 6

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
