中文摘要：
大定源瞬变电磁法目前已成为许多矿区水文地质勘查的首选方法。而煤矿老窑采空区出水已成为矿井突水的显著特点之一,因此,本文使用大定源瞬变电磁法对采空区的富水性进行了研究。作者基于电磁场的基本理论研究了大定源瞬变电磁场响应分布规律,并通过一个工程实例证明了瞬变电磁法在探测煤矿采空区富水性方面是有效的。
英文摘要：
Nowadays,large fixed TEM has become a primary method in many mining areas for hydro-geological survey.However,coal gob that leads to water bursts has become a notable characteristic in coal mines.Therefore,this paper studies property of water-bearing in coal gob using large fixed loop TEM.Based on the basic theory of electromagnetic fields,the author studies Electromagnetic Response Regularities of Large Fixed TEM and proves that TEM is validity in detecting property of water-bearing in coal gob by a project.
