摘　　要：为了针对难注水煤层进行有效注水,设计出了一种新型的煤层注水系统。该系统可以自身激发产生高压脉动波,从而改善煤体的通透性,增进煤体的润湿效果。现场试验显示,使用该系统进行注水,煤体的水分增量大约是静压注水的5.2倍,作用效果明显。与此同时,在煤体开采时产生的粉尘量也大大减少,其中割煤处的粉尘量减少最多,测试点的降尘率均在50%~70%,转载点处的降尘率最大,有效地改善了井下开采工作面的条件。In order to be effective infusion for hard coal seam water infusion,designed a new type of coal infusion system.The system can generate its own high-voltage pulse wave,thus improving the permeability of the coal and enhance wetting of the coal.Field experiments show that under the use of the new system,the water incremental in the coal is about 5.2 times than the static water infusion system,the role is obvious.At the same time,the amount of the dust during mining also greatly reduced,the cutting point reduces the maximum amount of dust,and the dust rate of each test point at 50% to 70%,the rate of dust at the point of reprint is maximum,which effectively improve the terms of the underground mining work face.
