Embodiment 1
[0039] There is an anticline geological structure in an open-pit mining area, and the inner dump just advances to the top of the anticline axis. The width of the anticline structure area is 1200m, and the direction is SE-NW. Due to the influence of the anticline structure, the drop of the coal seam reaches 270m, but the ground surface and the bedrock surface drop less than 100m. The coal seam transitions from a near-horizontal coal seam to an inclined coal seam. The inclination angle of the coal seam floor is large, resulting in the slope base of the inner dump site being inclined and stable. The performance is greatly affected, and at the same time, due to the increase in the amount of stripping, a larger space for soil discharge needs to be released. figure 2 It is a schematic diagram of the inclined base of the internal dump.
[0040] The current situation of the dump dump in the example open-pit mine has reached the level of 1420, and the specific steps of using the pres...
