摘要
绿色开采的理念是针对煤炭开采造成的严重环境问题提出的,它是从广义资源的角度认识和对待煤、瓦斯、地下水、土地、矸石等一切可以利用的资源,基于采动岩层运动规律防止或尽可能减轻开采煤炭对环境和其他资源的不良影响;目标是取得最佳的经济效益、环境效益和社会效益。构建的绿色开采技术框架包括保水开采、减沉开采、煤与煤层气(瓦斯)共采、矸石减排、煤炭地下气化等。
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.
