在可控条件测氡实验台上所进行的氡气浓度与温度关系的实验，得出了地下热源不仅可导致岩石的氡射气系数增高，而且在燃烧煤层所形成的高温、高压以及其它气体的向上拖曳作用下，氡向上的运移速率加大．通过氡气测量方法技术的研究以及实地探测地下火区的应用，认为地面测氡技术是一种在地形复杂地区探测地下火区位置与范围的有效手段． Experiments on the relationship between radon concentration and temperature in a controlled radon test station show that the underground heat source can not only increase the radon coefficient of the rock but also increase the temperature and pressure of the coal seam and other gases Of the upward drag, radon upward migration rate increases. Through the study of radon gas measurement method and the application of underground fire area in the field, it is considered that ground-based radon measurement is an effective method to detect the location and range of underground fire area in complex terrain.
