大恒煤矿废弃巷道矸石充填技术研究

Study on Gangue Filling Technology of Abandoned Roadway in Daheng Coal Mine

为实现大恒煤矿矸石不升井的目标,根据工程地质情况、现有设备和相关要求,通过对比选择充填工艺进行废弃巷道充填。选择3条废弃巷道作为充填巷道,并制定相应的设备改造方案,为矿山带来经济效益的同时提高巷道稳定性。

In order to realize the goal that the gangue does not lift the well in Daheng Coal Mine,according to the engineering geological situation,existing equipment and related requirements,the filling technology is selected to fill the abandoned roadway,three abandoned roadways are selected as the filling roadway,and formulate the corresponding equipment transformation plan to bring economic benefits for the mine and improve the stability of the roadway at the same time.
