摘　　要：为精确测量围岩松动圈范围,并合理设计煤矿井下巷道支护方式。采用地震波法对巷道松动圈进行测试,利用地震波波速在不同应力状态、不同岩石性质下的波速差异,确认巷道围岩松动圈的范围,本次在豫新煤业中采用YWZ11型地震仪进行测试,结果表明该矿在巷道开挖后,所测试的巷道的围岩松动圈范围在1.3~2.2 m之间。说明通过地震波法可以精确测量围岩松动圈,相比于其他测量方法,可以对巷道围岩情况进行快速精确测量,该方法为巷道的安全支护提供理论支持。In order to accurately measure the range of loose zone of surrounding rock and reasonably design the support mode of underground roadway in coal mine.The loose zone of roadway is tested by seismic wave method,and the range of loose zone of surrounding rock of roadway is confirmed by using the difference of wave velocity of seismic wave velocity under different stress states and different rock properties.YWZ11 seismograph is used in Yuxin coal industry this time.The results show that after roadway excavation,the range of surrounding rock loose zone of the tested roadway is between 1.3 m and 2.2 m.It shows that the surrounding rock loose zone can be measured accurately by seismic wave method,and compared with other measurement methods,the surrounding rock condition of roadway can be measured quickly and accurately.This method provides theoretical support for roadway safety support.
