中文摘要：

封闭不良钻孔是影响矿区安全生产的重要隐患之一,不良钻孔具有导通工作面顶板上含水层,增强顶板砂岩的富水性.针对这一问题,将直流电法电极顶入工作面顶板上,采用分站式进行数据采集工作.数据采集完成后,经过数据预处理和无穷远校正及巷道校正、剔除旁侧干扰等处理,将二维电阻率格式转换成三维电阻率格式,使用圆滑最小二乘法对数据进行反演,将反演完成后的数据导入三维可视化成图,圈定钻孔附近岩层富水区,为矿井水防治工作者提供决策.经工程验证后,说明该方法具有很强实用价值及推广价值.

英文摘要：

Sealed bad drilling is an important risk adverse impact mine production safety, the bad drilling has turned bad on roof drilling on the aquifer, enhanced roof sandstone rich water. To solve this problem, the electrode was putted into the top of the face roof, using of sub-station data collection. After the data collection was completed, after data preprocessing and infinity corrected and roadway correction, removed the side interference handling, the least squares method was used to smooth mapping of data retrieval, the data retrieval was imported into 3D visualization Mapping, drilling rock near the water-rich area was described, providing decision-making for mine water treatment workers.
