按现有的风量计算公式算得的控制井下氡子体α潜能浓度的风量能够保证矿工的辐射安全吗?显然有许多问题需要回答。本文从综合论述风流中氡及其子体浓度变化出发,分析了目前风量计算中应当进一步加以考虑的若干问题。包括:氡析出分布不均匀的影响,最高氡子体α潜能浓度与平均浓度的差别,风量的利用系数,风量分配的影响,风量计算过程中导出空气浓度的使用等问题。深入地研究它们对铀矿通风计算和管理都是有益的。
According to the existing wind calculation formula is calculated to control the potential concentration of radon progeny α underground gas miners to ensure the safety of radiation? Obviously, there are many questions to be answered. Based on a comprehensive discussion of the variation of radon and its progeny in the wind flow, this paper analyzes some problems that should be further considered in the calculation of the current air volume. Including: the uneven distribution of radon precipitation, the highest concentration of radon progeny α potential concentration and the average concentration difference, the use of air volume coefficient, the impact of air volume distribution, air volume derived during the calculation of air use and other issues. In-depth study of their uranium ventilation calculation and management are beneficial.
