中文摘要：

基于井底车场风流风路基本为巷道型通风空间的事实,本文开展了车场巷道内氡及其子体浓度分布规律的研究。从分析稳态时氡析出均匀的理想巷道内氡及其子体浓度分布出发,进而引入正源、负源的假定和氡及其子体浓度增长的叠加原理,推导出稳态时氡析出不均匀巷道内氡及其子体浓度分布方程。结合工程实践,对计算式进行了简化、分析和讨论。研究结果表明,限制巷道周壁氡的析出、保证稳定的通风量及较好的入风风质能达到有效控氡的效果。

英文摘要：

Based on the fact that airflow path in the shaft station generally pertained to the roadway type ventilation space, study on the regularity of radon and its daughters＇ concentration distribution in shaft station was carried out. Beginning with analysis of radon and its daughters＇ concentration distribution in the steady state of ideal roadway with a homogeneous radon exhalation rate, the steady-state distribution equations of radon and its daughters＇ concentration were deduced when radon emanation rate of roadway was inhomogeneous on the assumption of positive/negative superposition principle of radon and its daughters＇ concentration growth source and Associated with engineering practice, simplification, analysis and discussion on relevant mathematic equations were launched. The study results radon exhalation of rock face and ensuring a stable wind quality could effectively achieve the aim to radon control.
