摘要

    摘要
  • 摘要: 受岩溶及采空区的影响，湖南某煤矿附近出现了几个塌陷坑，危及居民的生命财产安全。为了查明附近的岩溶分布范围，采用等值反磁通瞬变电磁法进行探测。通过在调查区开展了6条线的等值反磁通瞬变电磁法工作，发现已知塌陷坑在探测结果中为低阻异常，其探测结果与已知情况吻合。结果表明，该方法在城镇中的探测效果较好，能够为城镇地质灾害调查提供详实的资料。
    Abstract: Affected by karst and goaf, several collapse pits have occurred nearby a coal mine in Hunan, endanger the people's life and property. In order to find out the distribution of karst, the opposing coils transient electromagnetic method was used. By doing 6 lines of opposing coils transient electromagnetic method in the survey area, it finds that the known collapse pits have low resistance characteristics. Its detection results and the known situation are very consistent. So, opposing coils transient electromagnetic method has a better capability of exploration in the town. It can provide detailed information for geological hazard investigation of town.
