复杂地下空区综合探测技术研究及其应用
|
摘要
采空区已成为矿山生产和工程建设过程中迫切需要解决的难题之一。分析了采空区带来的安全隐患和主要危害,总结了当前采空区探测中使用的主要方法和手段。针对复杂关联群采多空区情况,在现场摄影调查的基础上,提出了以探地雷达和瑞雷波法为主的综合探测技术。两种不同的先进物探技术,相辅相成,提高了采空区探测的准确度和精度。该方法在甘肃省厂坝铅锌矿地下群采空区探测中得到具体应用,基本查明了采空区的分布情况、大小情况和贯通关系,并对原有采空区平面布置图进行了修正。探测结果,为该矿由露天开采转入地下生产,提供了安全保障条件。
The mined-out areas have become one difficult problem cried for solving during mine production and engineering construction. Safety hidden trouble and main harm brought by mined-out areas are analyzed, and main methods and means used in detecting mined-out areas currently are summarized. For complicated associated many mined-out areas, composite detecting technology with generating ground radar(GPR) and Raleigh wave method is taken forward, on the base of on-the-spot photography investigation. Two different physical prospecting technologies, supplement each other, increase the veracity and precision of mined-out areas exploration. The method has been concretely used in underground group mined-out areas in Changba Lead-zinc Mine in GanSu province, and distribution, size and transfixion relation of the mined-out areas are found out basically. And ichnographies of mined-out areas are amended. The results have offered security guarantee condition when opencast working switches to underground working in the mine.
