| 摘 要： | 提出了煤矿绿色开采的概念，阐述了它的内涵和技术体系，绿色开采的理论基础为：开采后岩层中的关键层运动形成的节理裂隙与离层规律以及瓦斯与地下水在破断岩层中的渗流规律。绿色开采技术的主要内容包括：保水开采、建筑物下采煤与离层注浆减沉、条带与充填开采、煤与瓦斯共采、煤巷支护与部分矸石的井下处理、煤炭地下气化等。

| Abstract: | The concept of green technique in coal mining was proposed. Its connotation and technical system were explained. The theory foundation of the green technique in coal mining is the distribution behaviour of joints, fractures and bed separations, the seepage flow behaviour of methane and water in the broken rock strata caused by the key strata break after mining. The main content of the green technique in coal mining includes water-preserved-mining, coal mining under building and bed separation grouting to reduce surface subsidence, partial extraction and backfill mining, simultaneous extraction of coal and coal-bed methane. coal roadway supporting, underground discharge of partial rock refuse and underground coal gasification, etc. |
