摘　　要：赤马山铜矿因生产规模的扩大，致使原有的采矿方法已不能适应，因此必须加以改进。从技术经济角度考虑，采用中深孔分段矿房法代替原有浅孔留矿法，并选用了合适的爆破参数。The original mining method must be renovated because it cant meet the demand of expanding production capacity in Chimashan Copper Mine. On the view of technical economics, the sublevel mediumlong hole roomandpillar mining has taken the place of original shallow shrinkage stoping, as well the appropriate blasting parameters have be selected. So that the good results of application has be obtained.
