Description

Technical Field

[0001] This invention relates to a mining equipment and its stabilization method, repositioning method, and anchoring device for sidewall mining, belonging to the field of mineral resource technology for sidewall mining. Background Technology

[0002] Sidewall mining is a mineral resource extraction technique that begins at the exposed edge of a coal seam or vein. It is specifically designed for mining resources such as coal and ore that are unsuitable for open-pit mining due to deep overburden. In this method, a cutting mechanism is mounted on an extendable device, allowing the cutting head to penetrate deep into the mine for extraction. The extracted material is then transported out of the mine via a series of conveyors. As the mine length increases and the mining speed rises, greater forces are required on the cutting mechanism, necessitating sufficient stability from the sidewall mining equipment. The equipment must remain stable as the cutting mechanism and conveyors are pushed in and pulled out to accommodate the increased mass and vein variations with increasing mining depth. Furthermore, safety is a crucial consideration, as multiple mine shafts may be cut in parallel and may extend significantly. Inaccurate mining direction can weaken the coal pillars supporting the shafts, 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 orientation of the sidewall mining equipment need to be precisely controlled to maintain the accuracy of the mining direction, which further emphasizes the necessity of improving equipment stability. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a mining equipment and its stabilization method, repositioning method, and anchoring device for sidewall mining, which can improve the stability of sidewall mining equipment and accurately vertically position the anchoring device.

[0004] To solve the above-mentioned technical problems, the present invention is implemented using the following technical solution:

[0005] In a first aspect, the present invention provides an anchoring device for sidewall mining, comprising an anchor body, a first power linear motion system and a second power linear motion system. One end of the anchor body is provided with a cutting edge for cutting rich ore veins, and the other end is detachably connected to a drilling rig. The drilling rig is mounted on the first power linear motion system. The anchor body is provided with a guide sleeve for maintaining the vertical direction. At least one support member for vertical positioning is installed between the anchor body and the second power linear motion system. The second power linear motion system drives the at least one support member to move.

[0006] When the anchoring device is in the pulled-out state, the anchor body is pulled out from the rich ore vein, and the support is in the pulled-up position without contacting the rich ore vein.

[0007] When the anchoring device is in the drilling state, the first power linear motion system drives the drilling rig to drill the anchor body into the rich ore vein along its first axis direction. At the same time, it drives the second power linear motion system to position the support member and moves the guide sleeve that maintains the vertical direction downward to vertically position the anchoring device.

[0008] In conjunction with the first aspect, the anchor body is further described as a hollow cylindrical structure.

[0009] In conjunction with the first aspect, the radial thickness of the cutting edge is greater than the radial thickness of the anchor body.

[0010] In conjunction with the first aspect, the cutting edge is further selected according to the different geological conditions of the rich ore vein.

[0011] In conjunction with the first aspect, the first power linear motion system further includes a locking device for maintaining the anchor body in a specific position, the locking device being connected to the anchor body.

[0012] In conjunction with the first aspect, the anchoring device further includes a vacuum dust removal system, which includes a suction nozzle near the cutting edge, a flexible transport hose, a collection box, and a vacuum pump. One end of the flexible transport hose is connected to the suction nozzle, and the other end is connected to the collection box.

[0013] The anchor body, through the cutting edge, transports the fragments generated by the insertion into the rich ore vein to the collection box via the flexible transport hose;

[0014] One end of the collection box is connected to the vacuum pump via a dust filter.

[0015] In a second aspect, a mining device includes a conveying section assembly and a connecting device integrated with the mining device, the mining device being connected to a plurality of anchoring devices via the connecting device.

[0016] The anchor body is drilled into the rich ore vein along a preset direction through the cutting edge, and the mineral resources extracted from the rich ore vein are transported to the ground through the conveying section group.

[0017] In conjunction with the second aspect, the connecting device is a crossbeam, and the mining equipment is bolted to multiple anchoring devices through the beam structure.

[0018] Thirdly, a method for stabilizing mining equipment includes:

[0019] The mining equipment is positioned at a predetermined working location and connected to multiple anchoring devices via the connecting device;

[0020] The drilling rig is driven by the first power linear motion system, so that the anchor body in the anchoring device is axially driven to the rich ore vein along its first axis direction by the cutting edge, while the guide sleeve maintains the vertical direction of the anchor body during the insertion of the rich ore vein.

[0021] The position of the support member is adjusted using the second power linear motion system to stabilize the mining equipment.

[0022] Fourthly, a method for repositioning mining equipment, comprising:

[0023] Disconnect the connection between the mining equipment and the multiple anchoring devices;

[0024] Move the mining equipment to a new predetermined location, and move the existing anchoring device or install a new anchoring device at the new predetermined location;

[0025] The mining equipment is reconnected to multiple anchoring devices via the connecting device.

[0026] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0027] The sidewall mining anchoring device provided by this invention achieves precise vertical positioning and stable mining of the anchor body through a first power linear motion system and a second power linear motion system. The cutting edge at one end of the anchor body can efficiently drill into rich ore veins, while the detachable connection of the other end to the drilling rig and the design of the guide sleeve ensure the verticality and accuracy of the drilling process. In the pulled-out state, the pulled-up position of the support avoids contact with the ground, reducing wear and resistance. In the drilling state, the first power linear motion system drives the drilling rig to drill the anchor body into the ore vein along the axis, while the second power linear motion system positions the support and moves the guide sleeve, further enhancing the stability of the anchoring device. Furthermore, the mining equipment is connected to multiple anchoring devices through a connecting device, improving the stability and working efficiency of the mining equipment. The stabilization and repositioning methods of the mining equipment further optimize the mining process, allowing the mining equipment to be quickly and accurately positioned or repositioned as needed, thereby improving mining efficiency and flexibility. Overall, this invention enhances the stability of the mining equipment and improves the mining efficiency of mineral resources by precisely controlling the position and orientation of the anchoring device, while reducing operating costs and time.

[0036] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0037] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are used only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0038] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances. Example 1

[0039] See Figure 1 This 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 rich ore veins 4, and the other end is detachably connected to a drilling rig 6. The drilling rig 6 can be an electric, pneumatic, or hydraulic power drilling rig. The drilling 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 the 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.

[0040] It should be noted that the electrical wires or hydraulic lines 9 provide power to the drilling rig 6, and the drilling rig 6 also includes a drive device for axially driving the anchor body 2 and a rotating device for axially rotating the anchor body 2 in conjunction with the axial drive. The drive device is integrated with the rotating device, thereby enabling the anchor body 2 to be effectively inserted into the rich ore vein 4.

[0041] Furthermore, the anchor body 2 has a hollow cylindrical structure. First, when the hollow cylindrical anchor body is driven into the rich ore vein 4, some stratum material, such as rocks, fragments (62), and mud, enters the interior of the anchor body 2, fixing the anchor body 2 to the rich ore vein 4. The anchor body 2, filled with stratum material, has excellent vibration absorption performance. Second, 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 stratum material, it exhibits a high yield limit. Third, the hollow cylindrical structure is easier to insert into the rich ore vein 4 and easier to remove from the rich ore vein 4, thus enabling both rapid positioning and rapid dismantling of mining equipment.

[0042] In this embodiment of the invention, particularly when achieving deep anchoring, the radial thickness of the cutting edge 3 is greater than the radial thickness of the anchor body 2, that is, the wall thickness of the cutting edge 3 is greater than the thickness of the outer shell 5 of the anchor body. Furthermore, the cutting edge 3 at one end of the anchor body 2 can be selected according to the different geological conditions of the rich ore vein 4. Rich ore veins typically contain hard bottoms (such as rock and sandstone) and relatively soft bottoms (such as coal and mud). For hard bottom geology, a suitable cutting edge 3 is selected... Figure 4 and Figure 5 The cutting edge 3 is given as either thickened or serrated; for soft-bottomed geological conditions, a thin or 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.

[0043] Furthermore, the first power linear motion system 10 also includes a locking device connected to the anchor body 2, so that the anchor body 2 remains in a specific position during drilling.

[0044] See Figure 7 The anchoring device 1 also includes a vacuum dust removal system 61, which helps maintain a clean working environment and improve drilling efficiency. The vacuum dust removal system 61 includes a suction nozzle 66 located 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 via the flexible transport hose 67. The anchor body 2, through the cutting edge 3, transports fragments 62 generated from inserting into the rich ore vein 4 to the collection box 63 via the flexible transport hose 67. To maintain the vacuum within the vacuum dust removal system 61, one end of the collection box 63 is connected to the vacuum pump 68 via a dust filter 69, thereby protecting the vacuum pump 68 from harmful particles.

[0045] Alternatively, a water pipe 70 can be connected to the cutting edge 3 to supply water so that it can mix with the soil particles in the rich ore vein 4 to form a mud that is easier to transport. The water also helps to cool the cutting edge 3, thereby reducing the risk of overheating caused by long-term drilling and thus achieving a faster drilling speed. Example 2

[0046] See Figure 1 When the anchoring 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 between the anchoring device 1 and the rich ore vein 4, and bears and absorbs various vertical loads of the mining equipment, and the support 11 is in the pulled-out position without contacting the rich ore vein 4.

[0047] See Figure 2 When the anchoring device 1 is in the drilling state, depending on the type of drilling rig 6, the anchor body 2 is driven to rotate around its axis 7 by the vertical motion of the first power linear motion system 10 as it is driven to the rich ore vein 4 through the cutting edge 3. At the same time, the second power linear motion system 12 vertically positions the support member 11 and drives the guide sleeve 8 used to maintain the vertical direction to move, so as to accurately vertically position the anchoring device 1, that is, the vertical distance B of the anchoring device 1 relative to the rich ore vein 4.

[0048] Furthermore, the anchor body can be cut, with the plane area 15 of the rich ore vein 4 as a reference, to release the anchoring device 1 and leave a portion of the anchor body 2 in the rich ore vein 4. In actual sidewall mining, 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 obstruct the movement of vehicles. Example 3

[0049] Figure 3 Another type of second anchor body 20 is shown, which has a second cutting edge 21 detachably connected to one end and a connection profile 22 for connecting to a second drilling rig (the same as the drilling rig in FIG1) at the other end. The second anchor body 20 rotates about its second axis 23, and the radial thickness C of the wall (cylinder wall 24) of the second anchor body 20 is less than the radial thickness D of the second cutting edge 21, thereby making it easier for the second anchor body 20 to be inserted into the rich ore vein 4 in the direction of the second cutting edge 21.

[0050] Figure 4 Another third anchor body 30 is shown, which has different characteristics from... Figures 1-3 The third cutting edge 31, and Figure 3 In comparison, the third cutting edge 31 has a larger axial thickness than the third anchor body shell 32, and the third anchor body 30 also has a weakened radial region 33. The radial region 33 makes cutting the anchor body 2 easier and enables the weakened region to be cut off quickly, for example... Figure 1 and Figure 2 transfer Figure 4 The third cutting edge 31 can easily cut through the planar area 15. In the process of sidewall mining, when encountering geological conditions with hard bottom (such as rock and sandstone), the third cutting edge 31 is used.

[0051] Figure 5Another fourth anchor body 40 is shown, which has a serrated fourth cutting edge 41. The fourth anchor body 40 rotates about its fourth axis 42 by the fourth cutting edge 41, while being axially driven to the rich vein 4 along the direction of the fourth cutting edge 41. Example 4

[0052] See Figure 6 This invention introduces a mining device, for Figure 1 and Figure 2 Taking the described anchoring device 1 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 located in Figure 2 The state shown.

[0053] In order to stabilize the mining equipment 50 by anchoring device 1 and thus maintain the orientation of the mining equipment 50 relative to the sidewall 54 being mined, 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.

[0054] Furthermore, the connecting device can be a beam structure or a clamp, and the mining equipment 50 is screwed to multiple anchoring devices 1 via the beam 13. Example 5

[0055] A method for stabilizing mining equipment, comprising:

[0056] The mining equipment 50 is positioned at a predetermined working position and connected to multiple anchoring devices 1 via a connecting device;

[0057] The drilling rig 6 is driven by the first power linear motion system 10, so that the anchor body 2 in the anchoring device 1 is driven axially to the rich ore vein 4 along its first axis 7 by the cutting edge 3, while the guide sleeve 8 keeps the anchor body 2 in the vertical direction during the insertion of the rich ore vein 4.

[0058] The position of the support member 11 is adjusted using the second power linear motion system 12 to stabilize the mining equipment through the anchoring device. Example 6

[0059] A method for repositioning mining equipment includes:

[0060] Disconnect the connection between the mining equipment 50 and the multiple anchoring devices 1;

[0061] The mining equipment 50 is moved to a new predetermined location, and the existing anchoring device 1 is moved or a new anchoring device 1 is installed at the new predetermined location;

[0062] The mining equipment 50 is reconnected to multiple anchoring devices 1 via a connecting device.

[0063] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
