摘要:Based on green mining idea, this paper developed a kind of filling material with coal gangue as coarse aggregate and designed underground-preparation system with the main processes being breaking, mixing and pumping. As a result of the research, the coal gangue pollution and surface subsidence problem was effectively solved and the load of lift transportation system reduced and the cost of filling technology cut down, which meet the concept of green mining. The industrial experiment verified the safety and stability of the system which can improve enterprises economic benefits and social environmental benefits.
