GIS支持下矿区岩溶陷落柱的综合探测技术

岩溶陷落柱是影响矿山安全生产的重要地质灾害之一，在采掘笔者提出的工程设计之前，预先探测陷落柱的空间位置和形态，可避免经济损失并保证煤矿高效安全生产。为此，论述了一种在地面综合探测陷落柱的技术，即在地理信息系统（Ｇｅｏｇｒａｐｈｉｃ Ｉｎｆｏｒｍ ａｔｉｏｎ Ｓｙｓｔｅｍ ， 简称ＧＩＳ）支持下，对遥感图像、地质采矿资料和实地调查资料进行多因素复合分析，圈定陷落柱的可能分布区，进而实施物理勘探，确定陷落柱的具体分布参数。实践表明，这是一种行之有效的技术方法

Integrated Detecting Technique for Karst Collapses in Mining Area Supported GIS

Karst collapse pillars are one of the critical geological disasters affecting the safety production in mine. Detecting the locations and shapes of the pillars before designing the mining engineering can avoid economic loss and ensure the safety in mine.A new technical approach is suggested for finding pillars by comprehensive surface prospecting supported by geological information system(GIS).Through compound analysis of remote sensing images,geological and mining data and on spot geological survey data with GIS,the probable distribution areas of pillars are determined.After that geological exploration is implemented on these areas to ascertain the locations and shapes of the pillars.Experiments in some mines proved that the comprehensive technical approach is effective.
