应用高密度电法探测煤田陷落柱

THE APPLICATION OF THE HIGH-DENSITY ELECTRICAL METHOD TO THE DETECTION OF COALFIELD DEPRESSED PILLARS

本文讨论了高密度电法探测煤田陷落柱的若干问题。应用边界单元法模拟了陷落柱各种因素变化对地电异常的影响，并给出了陷落柱边界划分方法。针对矿区内严重的地电干扰，给出了数据采集及资料处理的技术措施。应用结果表明，高密度电法可有效地探测煤田陷落柱。

The present paper deals with some problems concerning the detection of coalfield depressed pillars with the high-density electrical method. The boundary element method was used to simulate the influence caused by variation in various factors of the depressed pillar upon the geoelectric anomalies, and the method for delimiting the depressed pillar is given.In view of the grave geoelectric interference that exists in the ore district, the paper suggests some technical measures for data collecting and processing. The results of the application show that the high-sensity electrical method can be used effectively to detect coalfield depressed Pillars.
