综合电法技术在铝土矿采空区探查中的应用

Application of Integrated Electrical Method in Exploration of Goaf in Bauxite Mine

基于地球物理以及地质因素的变化特征,采用以瞬变电磁法为主、高密度电法为辅的综合电法技术探查山西省兴县杨家沟铝土矿采空区。探查结果为在5个矿体上方共探明13个异常区。对探查结果进行钻探验证,钻孔在异常位置均揭露出空区,证明了综合电法技术探查铝土矿采空区的可靠性。

Based on the change characteristics of geophysical and geological factors,a integrated electrical method with transient electromagnetic method as the main method and high-density electrical method as a supplement is used to explore the goaf of Yangjiagou Bauxite Mine in Xing County,Shanxi Province.The exploration results showed that 13 anomalous areas were discovered above the 5 ore bodies.The exploration results were verified by drilling,and the boreholes revealed empty areas at abnormal locations,which proved the reliability of the integrated electrical method to explore the goaf of bauxite mines.
