深部开采

浅部易采的矿产资源日趋枯竭，地下矿山向深部开采是必然趋势。从20世纪80年代起，煤矿的开采深度已经达到1300m。随着深度的增加，遇到的难题也逐渐出现。

Easy shallow mining of mineral resources are depleting and underground mining to deep mining is an inevitable trend.80 years from the 20th century , the coal mining depth has reached 1300m . As the depth increases , the problems encountered are also gradually emerged .
