| 摘 要： | 深矿井开采一般是指为开采距地表特定深度的煤炭而采取的开采技术。深矿井的特征是原岩压力大、矿体塑性大及矿山压力显现剧烈。在深矿井开采中,巷道的开掘和支护成本、工作量都要成倍地增加,并且在深矿井中地热问题也逐渐显现。

| Abstract: | Mining in deep mine generally refers to the mining technology apoted for mining the specific depth coal that is apart from surface.The characters of deep mine are larger raw rock pressure,larger ore body plasticize,mine pressure severe appearance.The cast and working capacity of driving and supporting tunnel increase several times over in mining deep mine.The subterranean heat problem gradually appears in the deep mine. |
