Abstract: According to the problems of complex auxiliary transportation system, difficult in construction organization and poor ventilation in the original design scheme in 21401 orbit crossheading of Chensilou Coal Mine, the paper optimized design scheme with the endless rope winch characteristics, which has the advantages of simple system, less engineering, convenient construction, short construction period, smooth ventilation, and calculated the yard line at the same time. The tunnel uses the anchor net spray support, pre-stressed anchor cable strengthening supporting technology, which has better supporting effect.
