摘　　要：玲珑金矿255主运巷处于复杂的地质环境条件下,构造活动带岩土体动力稳定性和岩体结构探测与地质超前预报是工程有效治理的前提.依据现场雷达探测分辨率要求,选定250 MHz屏蔽天线探测,找到空区隐患的准确位置和围岩特征,为255主运巷后期的加固与治理提供了依据.Ground penetrating radar (GPR) surveys were conducted in rock mass structure detection and advanced geological prediction for 255 roadway in Linglong Gold Mine of China. The targets of the GPR surveys were to abtain the near-surface mined-out area features associated with dynamically induced liquefaction and disturbances. The GPR survey results using a 250 MHz antenna at the sites of some examples show that GPR is useful to locate subsurface features in the mined-out area for hazard assessment.
