Abstract: Because of the high proportion of dirt in raw coal, the main shaft has a heavy workload for the lifting of a large amount of waste onto surface, Through the study of related underground factors like coal flow, positions of coal bunkers and workings, dropping height, etc., the TDS intelligent destoning system is set up underground. Practice shows that the use of the system has led to effective increase of hoisting capacity of the main shaft, improvement of run-of-mine coal, simplification of surface raw coal pretreatment system, cutdown of subsequent coal preparation cost and improved social and economic result, and can contribute to the realization of green coal mining operations.
