煤矿膏体充填绿色开采体系研究

Study on Green Mining System:Paste Filling of Coal Mine

为解放建筑物下压煤、延长矿井服务年限,对工作面进行了膏体充填,设计了科学完善的充填系统。结果表明膏体充填绿色开采能够较好解放呆滞储量,消化矸石山,保护地表环境和减少巷道掘进工程量,经济社会效益显著,具有广阔推广前景。

For liberating the pressure of the villages building to coal, and extending the service life of the mine,this paper designs a complete and scientific filling system by filling the workface with paste. The results show that the green paste filling system can be better able to liberate dull reserves,digest gangue, protect the surface environment and reduce amount of roadway excavation projects. It has significant economic and social benefit,and has a good promotion prospects.
