摘要
岱庄煤矿2351工作面采用膏体充填技术进行回采。为解决充填过程中工作面出现漏浆问题,提出了在充填区打设隔离墙的方法,利用浓度高、颗粒度大的矸石浆堵住泄漏点,取得了很好的实际效果。
Stoping with paste filling technology to mine is used in 2351 working face of Daizhuang coal mine. For solving mortar leakage problem on the filling process ,we put forward the view of setting up separating wall in filling areas and using gangue backfill paste of higher concentration and large grains in size to block the leakage, which has achieved good performance in the pratical application.
