| 摘 要： | 活性炭测氡法是近年来发展起来的一种新的探测方法，具有灵敏度高、精度高、抗干扰性强、探测深度大等优点，已经被应用在火区、断层、陷落柱以及采空区的探测中。分析了活性炭测氡法探测煤矿采空区的理论依据，给出了利用活性炭测氡法、结合瞬变电磁法探测古交市南岩村山鑫煤矿采空区的应用实例。进一步证实利用活性炭测氡法探测煤矿采空区是可行的。

| Abstract: | Active carbon radon measurement method is a newly developed detecting method.It has been used to detect fire areas,faults,collapse pillars,and mined-out areas.This paper investigates the basic principles of active carbon radon measurement for detection of coal mined-out area,and presents a real example of detection of coal mined-out area in Nanyan,Gujiao City.Comparison of results from the proposed method and TEM method illustrates the feasibility of the proposed method. |
