红透山矿深部采矿方法研究

红透山铜矿进入深部千米以下开采后，原用的浅孔留矿法和水平分层充填法，聘采场失稳引起贫化，损失，安全事故“三高”现象。为此，开展了深部采矿方法的试验研究，试验研究的两步开采法的围怪稳定性及经济指标均居国内领先。对我国地下矿深部开采具有很大意义。

Investigation on Deep Mining Method for Hongtoushan Copper Mine

When Hongtoushan Copper Mine came into its deep mining at a depth of minus 1000 m,the originally used shallow hole shrinkage mining and horizon slicing filling caused the stope unstability which led to high dilution,high loss and many safety accidents.Therefore,experimental research has been done on deep mining methods.The results have shown that two stage mining is in the lead in China in its wall rock stability and economical indexes,which is of great interest to China's undergroud deep mining.
