Mining in deep copper mines of Zijinshan Gold-Copper Mine is exposed to a series of problems such as mining safety,efficiency and cost.So the layout form of large-hole drilling chamber,borehole layout,ore room bottom structure for ore drawing are optimized,which in field industrial test conducted achieves good technical and economic profits:preparation and cutting volume is reduced by about 20 %,the filling volume is reduced by about 500 m³,large-hole drilling volume decreases by about 9 %,and 695 400 yuan at cost reduction and efficiency increase can be achieved in a single ore room accumulatively.The optimization improves economic and social benefits for an enterprises and can be used as a reference by similar mines.
