小秦岭金矿巷道物探方法有效性讨论

Discussion on the effectiveness of geophysical prospecting methods for tunnel in Xiaoqinling Gold Mine

对比分析了多种物探方法在小秦岭金矿某巷道内的探测效果,总结出激发极化法探测巷道附近低阻高极化体,高密度电阻率法、瞬变电磁法追索有一定埋深的低阻体的巷道内探矿方法组合。

Based on comparison and analysis of the exploration effects of various geophysical methods used in tunnels of Xiaoqinling Gold Mine,the combination of prospecting methods is concluded that the induced polarization method can be used to detect the low resistance and high polarization body near the tunnel,and both the high density resistivity method and transient electromagnetic method used to search for low resistance body with a certain buried depth inside the tunnel.
