摘要： 声波测试是当前测试煤矿深井巷道围岩松动圈范围的一种比较准确的方式。随着深井巷道的推进，巷道附近
一定范围内的围岩由于前期爆破和后期围岩内部应力调整，会产生较多的裂隙和形变。而围岩的岩性、裂隙发育程度、
应力分布情况都会显著影响声波在围岩中的传播速度。通过监测迎头推进过程中的围岩波速变化情况，分析了迎头推进
距离、岩性、巷道位置等对围岩松动圈的影响。

Abstract: Acoustic wave test is a more accurate way to test the scope of the loose zone of the surrounding rock in the deep mine
roadway. With the development of deep mine roadway, the surrounding rock in a certain range near the roadway will produce
more cracks and deformation due to the early blasting and the later internal stress adjustment of the surrounding rock. The
lithology, fracture development and stress distribution of the surrounding rock will significantly affect the propagation speed of the
sound wave in the surrounding rock. By monitoring the change of wave velocity of surrounding rock in the process of head-on
advancing, this paper analyzed the influence of head-on advancing distance, lithology, roadway location on the loose zone of
surrounding rock.

Key words: acoustic wave test; lithology; roadway location; advancing distance
