摘　　要：基于九里山矿15061掘进工作面回风巷的水力掏槽试验,根据相关理论,对发生不同等级突出时,抛出煤的堆积长度进行了计算,并计算了在不同地点、不同级别突出冲击波引起的压力差值。Based on the hydraulic cutting experiment in the return airway of 15061 tunneling working face, accoi：ding to the related theories, calculate the different grades of outburst throwing coal accumulation length and the difference of stress caused by different grades outburst shock waves at different distances.

关 键 词：水力掏槽 突出煤抛出长度 突出冲击波 压力差
