老窑采空区的探测技术与实例研究程建远

针对老窑不同的采煤方法（如壁式开采、房式开采）、不同的采空区类型（如工作面采空区、巷道采空区等）以及采空区内充填物质的差异等多种复杂情况，讨论了老窑采空区的地震波场和电磁波场响应，结合一些典型工程实例，总结了老窑采空区与老窑巷道在二维、三维地震资料上的判识标志以及视电阻率断面上的显示特征，提出了小煤窑采空区快速检测的最佳技术组合，即综合利用遥感地质影像分析、地面地质调查、地面地震与电法勘探以及钻探验证等多种手段相互配合，能够实现采空区的多方法、多参数综合探测，减少多解性，提高综合探测精度.

The detection technology of excavated region in coal mine and case study

Based on the characteristic feature of different mining methods(long wall and room-pillar mining),dif- ferent void(working face void and roadway void and others),different filling materials in void area and other com- plicated situations,the 2D and 3D seismic and electromagnetic response in mined-out area and abandoned gallery were studied,which were supported by some typical engineering examples.The result shows that the integrated methods of remote-sensing,seismic exploration,electromagnetic detecting and drilling is the best technology combi- nation,which has the characteristic of multi-methods,multi-parameters to reduce the uncertainty of interpretation and achieve a high precision.
