摘　　要：利用探地雷达作为煤矿井下地质预报的手段,结合工程实例,采用50、200MHz 2种频率天线对山西某煤矿井下工作面及底板地质异常体进行预报。经过实际揭露,发现此方法可有效探测出地质异常体且探测距离提高到了50 m,突破了现有30 m的探测限制,同时精度可达3 m。As an advanced method, ground penetrating radar is commonly used in the geological prediction. Combined with the engineering project example, on the basis of excavation faces and roadway floor in a coal mine of Shanxi province,geological prediction were made with 50 and 200 MHz two frequency antenna. The spot excavation indicates that this method can accurately detect the geological anomaly,and the detection of roadway distance has been improved to 50 m, breaking the present 30 m detection depth limit. Meanwhile, the geological disaster source with a diameter over 3 m could be detected.
