两种物探方法在薄层矿体断层探测中的应用

Application of two geophysical methods in fault detection of thin orebody

为消除坑透法在薄层矿体回采工作面探测中的局限性,选择瑞雷波技术作为辅助物探手段,对揭露断层200m范围进行针对性探测,结合地质及补充钻探资料分析,排除一个干扰异常,圈定断层延展范围,实际结果证明,探查结果与实际揭露情况很好吻合。

In order to eliminate the limitations of pit penetration method in the exploration of the working face of thin-layer ore body,Rayleigh wave technology is selected as an auxiliary geophysical exploration method to detect the 200m range of the exposed fault.Combined with the analysis of geological and supplementary drilling data,an interference anomaly is eliminated and the fault extension range is delineated.The actual results show that the exploration results are in good agreement with the actual exposure.
