摘要
运用遥感和地理信息系统技术,对晋城矿区凤凰山矿进行了陷落柱分布预测。研究了陷落柱的遥感特征。从遥感图像中提取矿山环形和线性构造及热异常区;同时结合现有地质、采矿资料进行分析,总结陷落枉的分布规律。在此基础上,应用 ARC/INFO地理信息系统进行多因素复合分析,预测陷落柱的可能分布区,进而实施实地物探验证。结果表明,这种探测技术方案效果好,费用省。
Using remote sensing and geographic information system(GIS)techniques,this pa- per discusses the prediction of pillars of karst collapse in Fenghuangshan Mine,Jincheng mining area.The remote sensing characteristics of pillars of karst collapses are studied.The images about circular and linear structures and thermal abnormal regions are extracted. Meanwhile,geological and mining data are used for drawing the distribution laws of pillars of karst collapses.On the basis of these,ARC/INFO GIS was utilized to carry out multi-elements composite analysis,and the possible distribution regions of the pillars were determined.Then,the locations and shapes of pillars were verified by geophysical pros- pecting.The results show that the comprehensive surveying techniques and methodologies are effective and economic.
