摘要:
铀矿井下的独头巷道是氡及其子体浓度分布很高的场所。为指导抽出式通风独头巷道的排氡和排氡子体通风设计,初步完善了独头巷道通风气流中氡浓度与氡子体α潜能浓度之间的简化数学关系,分析了通风阻力对独头巷道岩壁氡析出率的影响;分别得出了抽出式通风独头巷道风流中氡浓度与氡子体浓度分布的数学计算模型,利用该模型分别得到了排氡和排氡子体最小风量的计算公式;针对具体的独头巷道,研究了巷道内氡浓度及氡子体浓度的分布规律以及排氡和排氡子体最小风量的变化规律。研究结果表明,距离抽出式通风独头巷道入口越远,巷道内氡浓度及氡子体浓度越高,氡及氡子体的浓度均随通风量的增大而...
摘要(英文):
Background: The blind roadway is one of the most important places where radon and its progeny's concentration is high in uranium mine exploitation. Purpose: The aim is to guide the design of exhaustion of radon and its progeny in blind roadway. Methods: The simplified mathematical relationships were primarily improved between radon concentration and radon progeny alpha potential energy concentration in the wind in uranium mine, and the influence of ventilation resistance force on rock wall radon release rate was analyzed; the mathematical calculation models of distribution for the concentratio...
