根据我们多年来对我国煤矿区一些不同类型的岩溶水中氡气的测量和分析,逐步认识到,地下水中的氡含量与地下水的径流条件、围岩性质及流量等有着一定的关系。近几年来,我们对峰峰矿区及外围的重要水源-奥陶系灰岩岩溶水中的氡,进行了多次的测量。结果表明,该矿区奥陶系灰岩岩溶水中的氡含量的低值区,基本与该含水层富 According to our measurement and analysis of radon in some different types of karst water in China’s coal mining area over the years, we have gradually realized that groundwater radon content has a certain relationship with groundwater runoff conditions, rock properties and flow rates. In recent years, we conducted a number of measurements on radon in the karst water of the Ordovician limestone, an important source of water in and around Fengfeng Mine Area. The results show that the low value area of ​​radon in karst water of Ordovician limestone in this area is basically similar to that of aquifer
