矸石充填沿空留巷技术

Technology of waste filling and reserving tunnel along goaf space

通过分析充填工作面矿压规律、采动影响范围、顶底板移近量及移近速度等参数,确定充填面支护技术参数,采取端头塑性矸石袋墙护巷沿空留巷,实现了矿井绿色开采。

The technical parameters of filling surface support is determined by analyzing the filling mining face pressure regularity, mining influence range, roof and floor closer and closer to the speed of parameters. The plastic waste rock bag wall supporting roadway in the ends reserving tunnel along guaf, green exploitation is . achieved in Huafeng coal mine.
