Generally, open-site mining, caving mining and filling mining are adopted. At present, the filling method has developed into a series of mining processes and technologies such as high-layer filling, segmented filling and stage filling. Different ore body occurrence conditions, goaf existence status, maintenance methods, ground pressure management, etc. determine different mining methods.

[0021] 2.

[0043] The filling method of a mining device for thick and large ore bodies in high altitude areas comprises the following steps:

[0044] S1. Alternately divide the ore body into chambers and pillars, and first use the open-field method to recover the pillars;

[0045] S2, put the slag into the feed shell 3, and control the motor feed motor 101 to drive the collecting wheel 11 to rotate, so that the slag can be initially crushed and enter the device, and the driving motor 42 is started to drive the driving worm 43 to rotate, so that the crushing column 13 crushes the slag inside the crushing shell 12, and the slag is crushed and screened by setting the blocking rod 19, and the slag is graded by the screening plate 22 for easy deployment and mixing with cement ash, and water is added again to stir to form a cementitious material.

[0047] S4, put the slag into the feed shell 3, and control the driving motor 42 and the linkage motor 15 to operate, crush and screen the slag, and grade the slag again, and perform a non-cemented filling in the mine room.

[0048] The implementation principle of the mining device and filling method for thick and large ore bodies in high-altitude areas of the embodiment of the present application is as follows: when conducting mining operations, the ore body is first divided alternately into mine rooms and ore pillars, and the ore pillars are first mined using the open field method; in the completed or partially completed ore blocks, a series of tunnels are excavated to divide the stages into ore blocks, and mining preparation work is performed to create conditions for pedestrians, ventilation, material transportation, rock drilling, and ore placement in the ore blocks. Common mining tunnels include stage transportation tunnels, shovel loader ore tunnels, prospecting tunnels, and mine exit rivers. Tunnel, ramps, etc. are all drilled with 281 hydraulic rock drilling trolleys, and the drilling and blasting method is used for construction, and the slag removal machine is loaded with self-unloading trucks to remove slag. For some parts where the 281 hydraulic rock drilling trolley is inconvenient to construct, a manual handheld YT-28 hand pneumatic drill is used for drilling, and the vertical shaft is constructed by the reverse drilling method. The mechanization of mining engineering construction is realized, the construction cycle frequency is accelerated, and the construction efficiency is guaranteed. Reduce the input of manual teams during the construction process, reduce the long working time under the hypoxic conditions of the plateau, reduce the oxygen content in the personnel, reduce the construction efficiency of the personnel and the great damage to the body, and reduce the incidence of safety hazards, so as to save man-hours, reduce construction costs, improve safety factors, and reduce the difficulty of operation. In the ore blocks where the mining work is being carried out or has been completed, the excavation work in the cutting project is completed to obtain the reserve mining volume. It includes: cutting horizontal tunnels, cutting well-connected tunnels, and cutting skylights. The cutting horizontal tunnels and cutting well-connected tunnels are drilled by 281 hydraulic rock drilling trolleys, and the drilling and blasting method is used for construction. The slag removal machine is equipped with a self-unloading truck to remove the slag. The cutting skylight adopts the VCR method of one-time well construction technology. The VCR method of one-time well construction technology is simple to operate, has good working conditions, a short construction period, a low risk factor, and a high degree of safety.

[0049] The slag is put into the feed shell 3 through the conveyor belt, and the feed motor 101 is started to drive the feed wheel 102 to rotate, so that the feed wheel 102 pushes the collecting wheel 11 to rotate inside the feed shell 3, and the hook plate 112 on the surface of the collecting wheel 11 is used to cut the large pieces of slag entering the inner side of the feed shell 3 into pieces and enter the inner side of the crushing shell 12. The slag will stay inside the crushing shell 12 due to the obstruction of the blocking rod 19, and the pushing motor 42 is started to drive the pushing worm 43 to rotate, so that the pushing disk 5 rotates and drives the adjusting block 6 below to rotate around the center, so that the sealing plate 7 is driven to rotate, and the sealing plate 7 drives the crushing column 13 to rotate inside the crushing shell 12 around the center of the sealing plate 7 through the connecting rod, and the crushing shell 12 and the crushing column 13 are used to squeeze and crush the slag;

[0050] By starting the adjusting motor 8 to drive the adjusting threaded rod 9 to rotate, the adjusting threaded rod 9 can rotate to adjust the position of the adjusting block 6, thereby changing the matching torque between the sliding block 61 and the pushing disk 5, so as to adjust the sealing plate 7 to produce different rotational extrusion forces under the same torque;

[0051] By starting the linkage motor 15 to drive the linkage rod 16 to rotate, the linkage gear 161 pushes the linkage ring 17 to rotate, and the linkage ring 17 drives the baffle rod 19 to rotate uniformly. The qualified slag crushed by the crushing shell 12 and the crushing column 13 falls from the gap of the baffle rod 19 and is discharged along the lower hopper 18, and falls onto the top of the screening plate 22. The linkage rod 16 rotates, so that the eccentric wheel 162 pushes the screening plate 22 to slide back and forth on the inside of the discharge channel 21. By arranging a blocking rod 23 on the inside of the discharge channel 21, the slag is prevented from rolling down directly without being screened. By arranging a material blocking slope 24 on the inside of the discharge channel 21, the screening plate 22 can cooperate with the material blocking slope 24 when moving to prevent the slag blocks from blocking the small holes on the surface of the screening plate 22. By arranging different hoppers 25, slag particles of different diameters can be collected and divided.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
