摘　　要：本研究以狮子山矿十八中段开拓巷道为工程背景,运用单孔声波测量法,对深部开拓巷道掘进爆破扰动下围岩松动圈演化规律影响进行了现场测试,并对采集的数据进行了分析研究,得出了爆破活动诱发围岩松动范围及演化规律。研究结果表明:狮子山矿十八中段开拓巷道围岩松动圈的大小为0.90~1.35 m,松动圈受巷道掘进爆破作业的影响范围约为24 m。The engineering background of the study is the development tunnel of 18 mining level of Shizishan mine,the acoustic measurement method of single hole is applied for the site test of the evolution law of the surrounding rock broken rock zone under the blasting disturbance of the deep roadway excavation,the analytical investigation is done for the collected data,so that the looseness range and evolution law of surrounding rock induced by blasting activities has been received. The study results show： the size of the broken rock zone of the surrounding rock of the development tunnel in 18 mining level of Shizishan mine is 0. 90 - 1. 35m; the influence range of broken rock zone affected by the blasting operation of roadway excavation is 24 m.
