[0020] Example 1 Based on the occurrence characteristics and mining technology conditions of steeply dipping thin veins, this embodiment provides a vertical mining device suitable for steeply dipping thin veins, including a mobile winch device 1 and a cutting swing support device 2. The mobile winch device 1 is used to travel in the horizontal roadway 3.1 of the mine and pull the cutting swing support device 2 located in the vertical roadway 3.2 of the mine. The cutting swing support device 2 is used to perform downward cutting operations in the vertical roadway 3.2 of the mine, and moves downward by gravity or a telescopic mechanism. The above-mentioned vertical mining device changes the current situation of lack of mining equipment and technology for steeply dipping thin veins, realizes efficient, safe and economical mining, and achieves the purpose of improving the ore grade of steeply dipping thin veins, reducing ore dilution, and improving the economic benefits of the mine.

[0021] In the above-mentioned vertical mining device applicable to steeply inclined thin veins, the mobile winch device 1 includes a frame 1.1, a traveling mechanism 1.2, and a traction mechanism; the traveling mechanism 1.2 is installed below the frame 1.1; the traction mechanism includes a drum 1.3.1, a wire rope 1.3.2, and a drum drive assembly; the drum 1.3.1 is rotatably mounted on the frame 1.1 and is driven to rotate by the drum drive assembly; the wire rope 1.3.2 is wound on the drum 1.3.1, and the extended end is connected to the cutting swing support device 2.

[0022] The mobile winch device 1 moves in the horizontal mine roadway 3.1 through the walking mechanism 1.2. Since the mine roadway surface is rugged and has poor pressure bearing capacity, this embodiment adopts a tracked walking mechanism, which has good passability and off-road capability, and has a large ground contact area, which can distribute the weight of the device, reduce the pressure on the road surface, and thus protect the road surface from damage.

[0023] In the above-mentioned vertical mining device applicable to steeply inclined thin veins, the mobile winch device 1 further includes a horizontal roof support mechanism and a horizontal floor support mechanism; the horizontal roof support mechanism is used to support the roof 3.1.1 of the mine horizontal roadway; the horizontal floor support mechanism is used to support the floor 3.1.2 of the mine horizontal roadway.

[0024] When the cutting swing support device 2 is in the downward cutting operation state or the upward traction and retraction state, the mobile winch device 1 is in a stationary state. The horizontal support mechanism is in contact with the roof 3.1.1 of the mine horizontal roadway, and the horizontal support mechanism is in contact with the floor 3.1.2 of the mine horizontal roadway, which ensures the stability of the mobile winch device 1 in the mine horizontal roadway 3.1, and at the same time ensures the stability of the cutting swing support device 2 during the hoisting process.

[0025] In this embodiment, the horizontal top support mechanism includes a horizontal top support cylinder 1.4 mounted on the frame 1.1, and the horizontal bottom support mechanism includes a horizontal bottom support cylinder 1.5 mounted on the frame 1.1. The horizontal top support cylinder 1.4 is provided with at least two (e.g., four cylinders) to form a surface support and contact the top plate 3.1.1 of the mine horizontal roadway. The horizontal bottom support cylinder 1.5 is provided with at least two (e.g., four cylinders) to form a surface support and contact the bottom plate 3.1.2 of the mine horizontal roadway.

[0026] Because the cutting swing support device 2 generates significant vibration during cutting operations in the vertical mine roadway 3.2, this embodiment employs a gear transmission for rotating the drum 1.3.1, which offers higher operational stability. The drum drive assembly includes a motor 1.3.3, a reducer 1.3.4, a drive gear 1.3.5, and a driven gear 1.3.6. The motor 1.3.3 is mounted on the frame 1.1, with its output end connected to the input end of the reducer 1.3.4. The output end of the reducer 1.3.4 is connected to the drive gear 1.3.5. The driven gear 1.3.6 is fixedly mounted on the first end of the drum 1.3.1 and meshes with the drive gear 1.3.5. The diameter of the driven gear 1.3.6 is larger than the diameter of the drive gear 1.3.5.

[0027] In the aforementioned vertical mining apparatus suitable for steeply inclined thin veins, the mobile winch device 1 further includes a braking mechanism 1.6 for braking the drum 1.3.1. In this embodiment, the braking mechanism 1.6 includes a brake pad and a hydraulic clamp; the brake pad is fixedly installed at the second end of the drum 1.3.1 and rotates with the drum 1.3.1. The hydraulic clamp achieves braking by clamping the brake pad. The entire structure is simple and the braking is reliable.

[0028] In the aforementioned vertical mining apparatus suitable for steeply inclined thin veins, the mobile winch device 1 further includes a guide mechanism 1.7 rotatably mounted on the frame 1.1; the wire rope 1.3.2 is led out from the drum 1.3.1, passes around the guide mechanism 1.7, and connects to the cutting swing support device 2. The guide mechanism 1.7 improves the stability of the drum 1.3.1 during winding and unwinding, and prevents the wire rope 1.3.2 from becoming tangled.

[0029] In the above-mentioned vertical mining device applicable to steeply inclined thin veins, the mobile winch device 1 also includes an oil tank pump station 1.8 and an operating platform 1.9 mounted on the frame 1.1.

[0030] In the above-mentioned vertical mining device applicable to steeply inclined thin veins, the cutting swing support device 2 includes a cutting mechanism 2.1 and an electrical control box; the cutting mechanism 2.1 is connected to the wire rope 1.2, and the cable of the cutting mechanism 2.1 passes around the guide mechanism 1.7 and is connected to the electrical control box located on the frame 1.1, and is wound and unwound synchronously with the wire rope 1.3.2 to ensure the normal operation of the cutting mechanism 2.1.

[0031] In the aforementioned vertical mining apparatus suitable for steeply inclined thin veins, the cutting swing support device 2 further includes a support mechanism 2.2, a swing hinge pin 2.3, and a cutting swing cylinder 2.4. The cutting mechanism 2.1 and the support mechanism 2.2 are rotatably connected via the swing hinge pin 2.3, and the support mechanism 2.2 is connected to the wire rope 1.2. The two ends of the cutting swing cylinder 2.4 are respectively connected to the cutting mechanism 2.1 and the support mechanism 2.2. The angle of the cutting mechanism 2.1 is adjusted by the extension and retraction of the cutting swing cylinder 2.4 to adapt to the vein's orientation.

[0032] In the above-mentioned vertical mining device applicable to steeply inclined thin veins, the cutting swing support device 2 also includes a vertical support mechanism for supporting the roof plate 3.2.1 of the vertical roadway in the mine and a vertical support mechanism for supporting the bottom plate 3.2.2 of the vertical roadway in the mine.

[0033] When the angle needs to be adjusted according to the direction of the ore vein, the vertical top support mechanism will contact the top plate 3.2.1 of the vertical roadway of the mine, and the vertical bottom support mechanism will contact the bottom plate 3.2.2 of the vertical roadway of the mine, fixing the support mechanism 2.2 in the horizontal roadway 3.1 of the mine. Then the cutting mechanism 2.1 swings with the swing hinge pin 2.3 as the hinge point through the cutting swing cylinder 2.4.

[0034] In this embodiment, the vertical top support mechanism and the vertical bottom support mechanism are respectively the vertical top support cylinder 2.5 and the vertical bottom support cylinder 2.6 installed on both sides of the support mechanism 2.2; the vertical top support cylinder 2.5 is provided with at least two (e.g., four cylinders) to form surface support and contact with the top plate 3.2.1 of the mine vertical roadway; the vertical bottom support cylinder 2.6 is provided with at least two (e.g., four cylinders) to form surface support and contact with the bottom plate 3.2.2 of the mine vertical roadway; the hydraulic pipes of the cutting swing cylinder 2.4, the vertical top support cylinder 2.5 and the vertical bottom support cylinder 2.6 bypass the guide mechanism 1.7 and connect to the oil tank pump station 1.8 located on the frame 1.1, and are wound and released synchronously with the wire rope 1.3.2.

[0035] In the above-mentioned vertical mining device applicable to steeply inclined thin veins, the cutting swing support device 2 also includes a slipper guide mechanism 2.7 (including the form of a guide guard plate) connected to the cutting mechanism 2.1.

[0036] The mobile winch device 1 is controlled via the control panel 1.9 and uses the oil tank pump station 1.8 as its power source to drive the tracked walking mechanism. The horizontal top support cylinders 1.4 (≥2, e.g., 4 cylinders forming surface support) and the horizontal bottom support cylinders 1.5 (≥2, e.g., 4 cylinders forming surface support) also use the oil tank pump station 1.8 as their power source and are controlled via the control panel 1.9 to extend or retract. The motor 1.3.3 drives the reducer 1.3.4 to rotate the drum 1.3.1. The extension or retraction of the wire rope 1.3.2 is achieved through the guide mechanism 1.7 (which allows for independent guidance of the wire rope 1.3.2, cable, hydraulic pipe, etc.), and the braking mechanism 1.6 ensures that the drum 1.3.1 stops rotating.

[0037] The cutting swing cylinder 2.4, the vertical support cylinder 2.5 (quantity ≥ 2, such as 4 cylinders forming surface support), and the vertical bottom support cylinder 2.6 (quantity ≥ 2, such as 4 cylinders forming surface support) in the cutting swing support device 2 are all powered by the oil tank pump station 1.8 and controlled by the operating panel 1.9. The cutting mechanism 2.1 is mainly driven by the cutting motor, which drives the reducer to transmit torque through the cutting chain, so that the horizontal axis cutting head can also rotate synchronously to perform cutting operations.

[0038] Example 2 This embodiment provides a vertical mining method suitable for steeply inclined thin veins. It is a mechanized vertical mining method that mainly uses pillar mining and employs vertical or steeply inclined shafts (vertical shafts or inclined shafts) to directly penetrate the ore body. It is mined in sections from top to bottom, with simultaneous mining and backfilling. Specifically, it includes the following steps: S1, a directional drilling rig is used to drill a pilot hole from top to bottom in the upper part of the ore body to solve the problem of the pilot hole's penetration accuracy; S2, replace the reverse drilling bit in the lower part of the ore body and carry out borehole enlargement construction from bottom to top to form the mine vertical roadway 3.2; S3. Mining is carried out using the aforementioned vertical mining device suitable for steeply inclined thin veins. The mobile winch device 1 is placed in the horizontal mine roadway 3.1 above the ore body, and the cutting swing support device 2 is placed in the vertical mine roadway 3.2 of the first mining area. The horizontal support cylinder 1.4 extends out and contacts the roof 3.1.1 of the horizontal mine roadway, and the horizontal support cylinder 1.5 extends out and contacts the bottom 3.1.2 of the horizontal mine roadway. The mobile winch device 1 is fixed, and the drum 1.3.1 is driven to rotate in the forward direction, causing the cutting swing support device 2 to move downward. When it moves to the first cutting position, the vertical support cylinder 2.5 extends out and contacts the bottom 3.1.2 of the horizontal mine roadway. The vertical support cylinder 2.6 extends to contact the vertical roadway floor 3.2.2, and the support mechanism 2.2 is fixed inside the horizontal roadway 3.1. The cutting mechanism 2.1 performs the first cut. After the first cut is completed, the vertical support cylinder 2.5 and the vertical support cylinder 2.6 retract, driving the drum 1.3.1 to continue rotating in the forward direction, so that the cutting swing support device 2 continues to move downward to the second cut position. The vertical support cylinder 2.5 and the vertical support cylinder 2.6 extend to fix the support mechanism 2.2, and the cutting mechanism 2.1 performs the second cut until the first mining area is mined out. When the angle needs to be adjusted according to the direction of the ore vein, the vertical top support cylinder 2.5 and the vertical bottom support cylinder 2.6 extend to fix the support mechanism 2.2, and the cutting mechanism 2.1 swings through the cutting swing cylinder 2.4 with the swing hinge pin 2.3 as the hinge point to adjust it to adapt to the direction of the ore vein. In the working face roadway 4, a scraper transfer machine 5 and a retractable belt conveyor 6 are used to transport the falling ore. In the transport roadway, mine cars are used to transport the ore. S4, after the first mining area is completed, the vertical top support cylinder 2.5 and the vertical bottom support cylinder 2.6 retract, driving the drum 1.3.1 to rotate in the opposite direction, pulling the cutting swing support device 2 onto the mobile winch device 1, the horizontal top support cylinder 1.4 and the horizontal bottom support cylinder 1.5 retract, the mobile winch device 1 moves to the second mining area, the cutting swing support device 2 mines the second mining area, and at the same time fills the first mining area; S5. Repeat step S4 until all mining areas are mined and backfilled.
