基于INSAR与TRT的某小区地下采空区分析

冀北山区一小区毗邻发生采空塌陷某铁矿,附近居民较为恐慌.为探查小区地下是否存在采空区,采用INSAR遥感监测与TRT超前地质预报技术相结合的方法进行探查验证.通过验证分析,发现异常体为松散破碎带,即该破碎带为充填体或断裂破碎带,存在采空区的可能性小.这两种方法的联合应用,极大地提高了验证效率,可用于大范围的采空区勘查工...

Analysis of underground goaf in a small area based on InSAR and TRT

An iron ore mine collapse occurred in a small area in the mountainous area of northern Hebei Province, which caused panic among residents nearby. In order to detect whether there is goaf in the underground area, InSAR remote sensing monitoring and TRT advanced geological prediction technology are used for exploration verification. Through verification and analysis, it is found that the abnormal body is loose fracture zone, that is, the fracture zone is filling body or fracture fracture zone, and the possibility of goaf is small. The combined application of these two methods greatly improves the efficiency of verification, and can be used for large-scale goaf exploration.
