| 摘 要： | 基于石膏矿产的物性特征，根据断层（破碎带及含水裂隙）和矿体上覆的淋滤灰岩富含水特性差异，在视电阻率曲线上呈现良导电的低电阻率反映，推断和解译矿体周围岩体含水性分布情况及断层位置，取得了较好的地质效果。实践证明，可控源大地电磁法是一种可靠的、理想的矿山地质灾害勘察物探手段。

| Abstract: | Based on characteristics of the physical properties of mineral gypsum, the characteristic difference between faults （broken zone and water-bearing cracks） and water-rich overlay leaching limestone shows good electrical conductivity and low-resistivity in apparent resistivity curves, by which distribution of water in the surrounding rocks and faults location can be deduced and interpreted. Practice has proved that controlled-source audio-frequency magnetotelluric method is a reliable, idea/ geophysical way for mine geologic hazards exploration. |
