A large amount of roadways and chambers are excavated during underground mining for staff access and ventilation,as well as for transporting and raising the useful exploited minerals.In mining progress0 some road- ways and chambers will be damaged,and the others will be left in the deep stratum while the mine or working level are abandoned,resulting in permanent abandoned underground space.The abandoned underground space of mine ac- tually consists of two parts,namely,the underground space induced by roadways and chambers of the abandoned mines,and the roadways and chambers of the abandoned producing sections or working level in a production mines. The existence of the abandoned underground space will not only bring in great danger to the development of under- ground space and the mining of useful minerals in future adjacent areas,such as water inflow,gas rush-in,etc., but also produce land subsidence and some other environment problems in series.On the base of resolving the ground- water pollution and some other problems,performing innocent treatment for solid wastes with great harm by using the abandoned underground space of mine will resolve the double difficult problems simultaneously,i.e.,the treatment of both solid wastes with great harm and harm from abandoned underground space of mine.
