摘　　要：阐述了隧道隐伏煤层采空区对隧道施工及运营安全的影响及危害,并针对隧道内特有的工作空间,对比各种物探技术的应用情况,最终选择了抗干扰强、效率高的探地雷达技术对煤层采空区进行探测。结合几个工程实例,分析了探地雷达在高风险隧道隐伏煤层采空区探测中的具体应用情况,通过钻孔验证了方法的有效性和精确性。This paper first describes the adverse effect of coal seam goaf in tunnel on tunnel construction and operation, and then compares advantages and disadvantages of various geophysical technologies in the light of specific work space of the tunnel. GPR technology which has a strong anti-interference capability and high efficiency is adopted to detect the coal seam goaf. Combined with several engineering examples, this paper analyzes the coal seam goaf detection in high risk tunnel by using GPR technology, and verifies the validity and accuracy of GPR.
