地质雷达在金属矿山超前探测中的应用

Application of Geological Radar in Advanced Detection of Metal Mines

在金属矿山巷道掘进过程中,前方隐伏地质异常体极易引发事故,因此需要对巷道掘进面进行超前探测。采用天线频率为100 MHz的地质雷达对马坑铁矿巷道掘进前方进行探测实验,收集并分析地质雷达的超前探测数据,探索掘进前方的地质异常体情况,并通过实际开挖对分析结果做验证。结果表明,地质雷达超前探测技术在金属矿山中具有较高的预报精度,对含水构造等较为敏感,可为巷道开挖工作提供有效的技术支持。

In the process of roadway excavation in metal mines,the hidden geological anomalies in front are easy to cause accidents,so it is necessary to detect the roadway excavation face in advance.The geological radar with an antenna frequency of 100 MHz was used to detect the front of the roadway excavation in Makeng Iron Mine.The advanced detection data of the geological radar were collected and analyzed to explore the geological anomaly in front of the excavation,and the analysis results were verified by actual excavation.The results show that the geological radar advanced detection technology has high prediction accuracy in metal mines and is sensitive to water-bearing structures,which can provide effective technical support for roadway excavation.
