瞬变电磁法及EH-4在钼矿采空区探测中的应用
|
摘要
地下采空区的存在严重威胁着人们正常的生产生活,选取有效的方法对采空区探测有着重大的现实意义.本文探讨了瞬变电磁法和EH-4电导率成像法的方法技术以及在某钼矿采空区的应用效果.瞬变电磁法观测的是纯二次场,所以分辨率高,特别是对低阻异常体反应灵敏.EH-4电导率成像系统探测深度大,适用于各种复杂地形,可以有效的减少地形的影响,因此结合这两种方法对采空区进行综合探测,可以相互补充,提高对采空区评价的准确性.
The exist of underground mined-out areas seriously threaten human production and life,so it has a real meaning to explored the mined-out areas by effective measures.The paper introduces the application of Transient electromagnetic method(TEM) and EH-4 to the exploration of the mined-out areas.Because TEM measures the secondary field signal,it has high resolution,especially in low resistivity bodies.EH-4,which possesses very strong adoptability for the site and lager detecting depth,is reducing topographic influence efficiently,combing the two techniques,we can make comprehensive exploration to mined-out areas,therefore,the combination of these two methods to detect the mined-out area,we can complement each other to improve the accuracy.
