井下掘进出矸压缩实验研究探讨

Green-Mining-based, protection of surface and reduce the settlement practical problems, research various downhole lithology and different sizes of different mining waste rock in the deep underground mined-out area after filling the surface the relationship between the settlement so as to determine the waste rock fill mined-out area Best Trail degree and lithology, to minimize surface subsidence after the underground mining, tunneling fully utilized and green waste rock mining purposes.
