Concept of Green Mining and Its Technical Framework

With respect to the serious environment problems of coal mining,a new concept of green mining is proposed, which is related to viewing and treating coal, coal-bed methane, ground water,rock waste and any other useful resources in a broad sense as resources. It is based on the law of strata movement to prevent or to alleviate the adverse influence of coal mining on other resources and the environment as far as possible. The goal is to maximize the economic and social benefits. The technical framework of green mining includes water-preservation in mining areas, coal mining to retard surface subsidence,simultaneous extraction of coal and coal-bed methane, reduction of rock waste, underground coal gasification, and others.
