摘要
通过利用山西安全工程技术研究中心研制的煤自燃与测氡实验台,进行土壤中水分含量对氡浓度影响的模拟实验研究,得出地下水环境运动是氡迁移的重要影响因素,并结合实验室先前关于煤体程序升温氡迁移规律的实验数据,大胆假设水与氡地下运移模型并验证,对同位素测氡法火源探测的现场应用提供进一步的理论基础。
The influence of moisture content on radon concentration in soil was simulated through the use of Shanxi Safety Engineering Technology Research Center in coal spontaneous combustion research and radon laboratory bench, it is concluded that the groundwater environmental movement is one of the most important factors affecting radon migration, and combined with laboratory of coal tempera- ture programmed radon migration patterns of experimental data, the water and the underground radon migration model will provide theo- retical basis for further practical application.
