复杂条件下瞬变电磁法探测采空区技术应用

摘要

根据宽沟煤矿地表起伏较大、地层倾斜，两者形成“喇叭口”时，瞬变电磁探测法相邻测点地电断面剧烈变化，数据采集和处理解释较为困难，常规处理效果较差的状况，采取针对性处理方法，总结出复杂条件下应用地面瞬变电磁方法的技术对策，经钻探验证，与实际揭露吻合良好。%for the complicated terrain condition in Kuangou Coal Mine , it is very difficulty to collect and process data in the use of TEM.By taking targeted processing method , the technological measures of using TEM in complicated terrain condi-tions were summarized .The drilling verification shows that the results of TEM are accordance with the actual case .
