摘　　要：冲击地压是一种主要的矿山灾害,它的发生一般是突然的并难以预见的,所以容易造成人员及财产损失。因此需找一种经济有效的卸压方法以防治冲击地压就成为了矿山减灾工作的重要课题。与传统的大孔径机械钻孔方法及水射流钻孔方法相比,利用现有小孔径进行水射流割缝卸压的方法具有更良好的卸压效果,并且对设备的要求比较低。因而被证明是一种行之有效并易于推广的防冲方法。Rock burst is a kind of mine disaster , usually abrupt and difficult tobeforeseen ,which could cause personal casualty and property loss. Therefore, finding a economical and effective pressure relief method to prevent rock burst became a important subject of mine disaster reduction. Compared with large aperture machine--drilling and water jet machine--drilling, small aperture machine--drilling has better pressure--relaxing effect, lower remand to equipment. Therefore, it＇s a effective and easy to spread method to prevent rock burst.
