摘　　要：水闸墙是煤矿防治水的重要方法之一,一是为防止淹井,实现分区隔离所必须构筑的防水设施;二是在巷道出水时,堵水的一种设施。但是,在煤矿工作面出水时,能否用水闸墙来堵水?在煤矿工作面出水时,水闸墙有什么新的作用?本文通过一些案例进行了一些研究,认为:在煤矿工作面出水时,用水闸墙来堵水是不科学的;但是,在煤矿工作面出水时,用水闸墙可以防止因注浆堵水而增大水量产生的淹井问题,并且可以降低水压,防止注浆堵水过程中的跑浆;特别是水闸墙和充填采空区结合起来,防止注浆堵水过程中的跑浆效果更好。Sluice wall is one important method of mine flood control First,It is a indispensable waterproof establishment and it＇s aim is to achieve subarea to protect the wells from flooding.Secondly,it is also a water blocking establishment when the channel inrushing water.However,whether it is possible to use sluice wall to block water when the coal mine working face gushing water？ Does sluice wall has any new functions in blocking water when the coal mine working face gushing water？ This paper does some researches through some cases and consider that： it is unscientific to block water by sluice wall when the coal mine working face gushing water.However,when gushing water,the application of sluice wall can solve the problem that too much water flood the well which caused by grouting.And it also can reduce the water pressure,prevent the grout leak in grouting.It will have better effects in preventing grout leak if we combine the sluice wall and filling mined-out area two methods in grouting water.
