摘　　要：武平县萤石矿上部老空区较多,受采动的影响,可能沟通上部老空区积水,使得矿山安全生产存在重大隐患。为了保证矿山安全生产,水害防治重点是圈定老空积水区边界位置。由于该矿老空区的地质资料不全,无法进行老空区的实测,因此,根据水与岩石之间存在的电阻率差异,研究含水异常体与地电场之间的响应,建立含水异常体与围岩之间的电阻率关系,采用网络并行电法对老空区积水边界进行探测。结果表明电法探测得到的电阻率参数所划定的积水区边界与钻探验证的老空区积水边界基本一致。Great hidden dangers exist in Wuping County Fluorite Mine due to the seeper in upper goaf caused by mining influence.In order to ensure the safety production,the authors focus on the delimitation of the boundary position of goaf water,in which network parallel electrical method is applied according to the response resistivity differences between water and rock,response between the abnormal water bearing body and geo-electric field to establishing the resistivity relationship between abnormal water bearing body and surrounding rock.The results show that the boundary of water obtained by detecting the resistivity parameter with electrical method is basically identical to the boundary of goaf water drawn by drilling verification.
