摘　　要：陷落柱构造破坏煤系地层、降低煤炭资源储量,采煤工作面通过陷落柱,增加采煤成本,带来突水、瓦斯积聚风险,有必要在采煤工作面开展隐伏陷落柱构造探测。目前,采煤工作面的主要物探方法有地震波法和电磁法两类,作为精细地质勘探方法,探地雷达技术在隐伏陷落柱构造探测中发挥了重要作用。本文针对华阳一矿地质特点分析了陷落柱类型及其成因,采用有限时域差分法模拟了无充填型和充水型两类陷落柱构造的探地雷达数据,分析了不同构造的数据特征。通过100 MHz探地雷达对矿区内隐伏陷落柱构造进行了探测,探测结果表明:通过探地雷达剖面的目标频率变化及衰减幅度等特征,能够判别出陷落柱类型,为风险源排查和工程作业提供参考。Collapse column structure destroys stratum structure and increases coal mining cost.When the coal mining working face passes through the collapse column,the risk of water inrush and gas outburst will increase.It is very necessary to detect the collapse column in coal mining face.At present,the main geophysical prospecting methods in coal mining face are seismic wave method and electromagnetic method.Ground penetrating radar technology plays an important role in the detection of subsided column structure.According to the geological characteristics of Huayang No.1 mine,this paper analyzes the types and causes of collapse columns.The GPR data of unfilled collapse column and water filled collapse column are simulated by finite-difference time-domain method.The data characteristics of collapse column are analyzed.The collapse column in the mining area was detected by 100MHz ground penetrating radar.The detection results show that:through the characteristics of target frequency variation and attenuation amplitude of ground penetrating radar data,we can distinguish the type of collapse column.This provides reference for risk source investigation and coal mining operation.
