摘要
地下开采的矿山,经常会遇到巷道围岩的失稳问题。巷道围岩的稳定性不仅影响到工程的进度,同时也将严重影响人员和设备的安全,利用岩体声波速度来判断岩体的稳定性,愈来愈被人们重视,并广泛用于实践。通过声波对围岩稳定性分级试点进行分析验证,阐明了声波测试对围岩稳定性分析的有效性。
Underground mining of mines, often encounter the roadway rock instability problems. Roadway rock the stability not only affect the progress of the works, but also will seriously affect the safety of personnel and equipment Judging the speed of sound waves rock the stability of rock, more people were seriously and are widely used in practice. In this paper, acoustic rock of stability classification analysis of pilot certification, elaborated on the acoustic test the validity of the stability of surrounding rock.
