放顶煤液压支架后尾梁喷雾系统的应用

摘要

In 12111 fully mechanized caving mining face of Liuta Coal Mine, operating caving process will produce large amounts of dust. By technical transformation, tail beam spray system was used in caving hydraulic support and the effect of dust suppression was very good.%神东柳塔煤矿根据12111工作面放顸煤液压支架在操作放煤过程中会产生大量煤尘和粉尘的情况进行改造，在液压支架进水三通处引一条管路，通过后尾梁操作阀控制液控单向阀，将水路进入喷嘴处，达到喷雾效果，起到降尘的作用。
