摘　　要：中煤平朔安家岭矿区运煤铁路专用线局部出现坍塌的现象,严重影响了铁路运输的安全性。为了探明矿区铁轨周边空洞的分布范围、埋深等发育特征,应用二维多道瞬态面波探测技术进行了数据采集、处理和分析等步骤,完成了铁轨下疑似空洞异常引起的地层疏松低速区圈定,并采用瞬态面波对10 m以浅范围内低速异常区进行解释。In Anjialing mining area,the special railway line for transporting coal partially collapsed,which seriously affect the safety of railway transportation.In order to find out the distribution,buried depth developmental characteristics of mining area railway,this article applies the two-dimensional multi-channel transient surface wave detection technology for data acquisition,processing and analysis steps,completes the tracks down the suspected abnormal hole formation caused by osteoporosis low-velocity zone,and uses the transient surface wave for 10 m within the scope of shallow low anomaly explained.
