Abstract


In coal mining process,people usually only focuses on coal mining economic benefits , while ignoring the coal mining on the natural environment , the negative effects and produce . Often appeared in the ecological destruction and pollution after , just undertakes end-treatment . Rarely the exploitation of mineral resources and ecological environment photograph harmonious philosophy and engineering practice combined .The current treatment method of mined-out summarizing have six species , namely closed, caving, consolidate, all the pieces fall, partial tiberium spikes supporting and filling . Due to the geological conditions and mining conditions and other reasons, four kinds of can effectively solve the surface subsidence ect . But the partial tiberium spikes supporting method existing resources waste shortcomings , only filling is the most effective solution . This paper combines red mud of the cementing performance and cost of filling to analyze red mud gangue cemented filling the feasibility . In priority save coal resources, improve the mine resource recovery premise . Combined with pressure coal villages in the geologic condition, were calculated and analyzed various feasible mining scheme after , draw a red mud gangue cemented filling in from 180 km near .“three down one up”and press the coal mine is a large quantity of feasible conclusion .
