铜山铜矿前山矿区采矿方法的改进

The Improvement of the Mining Method of Qianshan Mining Area,Tongshan Copper Mine

针对铜山铜矿前山８４＃矿体采用分段崩落法存在通风困难、采场自燃和地压控制等几个主要问题，提出了改用分段空场嗣后充填采矿方法的试采方案。实验结果表明该方法通风效果改善，采场自燃得到控制。

In view of the main problems existing in the sublevel caving method used in mining 84 # ore body in Qianshan area,Tongshan Copper Mine such as difficult ventilation,stope self combustion and ground pressure control,an alternative for test mining is suggested which consists of sublevel open stoping followed by filling.Its test results have shown an improved ventilation,controlled stope self combustion and less ground pressure activity.
