Embodiment
[0029] 1. The construction process is simplified. For the construction of the downhill roadway, the problem of difficult construction technology in the downhill tunneling at a large angle is solved through the graded and slope-changing design method.
[0030] 2. Transportation safety is guaranteed. In the transportation link of each slope change point, by appropriately reducing the slope change angle, the instantaneous impact force of the transportation equipment on the steel wire rope is weakened, the sports car accident during the transportation is effectively contained, and the safe production of the mine is guaranteed from the design source.
[0031] (2) Economic benefit analysis
[0032] Reduce the cost of replacing wire ropes. Before adopting the step-by-step gradient technology, a working face needs to replace the steel wire rope twice during the process from excavation to coal mining production. After adopting graded slope change technology, by reducing the impact f...
