摘要
隐伏导水陷落柱的存在是矿井安全生产的重大隐患,是矿井防治水的重点、难点。目前单一探测手段难以准确探测隐伏导水陷落柱。根据地质、水文条件在宏观上圈出隐伏导水陷落柱范围,然后利用三维地震、电磁法、化探、放水试验、水质分析、钻探等综合勘探手段,逐步缩小异常区范围。实践证明,这种从宏观到微观,从整体到局部,有效利用各种勘探手段,逐步逼近,能够准确定位隐伏导水陷落柱。
The existing of hidden water flowing subsided columns is major hidden trouble in mine safety in production, is emphasis and nodus in mine flood control. To use monadic means is difficult to correctly locate hidden water flowing subsided columns. According to geological and hydrogeological conditions block out hidden water flowing subsided column limits macroscopically, then use integrated prospecting means of 3D seismic, electromagnetic method, geochemical prospecting, dewatering testing, water quality analysis and drilling, narrowing anomalous extent step by step. The practice demonstrated, the methodology of from macroscopic to microscopic, from entirety to locality, efficaciously utilized all sorts of prospecting means, to successively approximate the hidden water flowing subsided columns with accurate positioning.
