4、 the exploration line of 47 55. Mining method for the short-hole shrinkage method, the digging height is 50 meters, and in 5 phases layout the roadway .The ventilation system adopt the central-diagonal ventilation system, the main shaft use the single cage to hoist, and the two ventilation shafts layout in the two wings of the collapse area of the ore body as a safety exit. The drainage system adopt the integrated drainage. In addition, such the size of the shaft section, the size of
