为科学合理地评价铀矿井下空气环境质量,通过对广东某铀矿及辽宁某铀矿井下空气环境的调查,分析了铀矿井下空气环境的特点及其危害,确定氡、氡子体、铀矿尘、CO、NO2及矿井气候6个指标为影响铀矿井下空气环境质量的主要因素,依此建立铀矿井下空气环境安全评价指标体系。采用模糊综合评价法建立了铀矿井下空气环境安全评价模型,并采用熵权法客观赋权的方式确定各评价指标权重,避免了评价过程中人为主观因素的影响,从而得到比较客观的评价结果。以南方某铀矿井为例,运用建立的评价模型对其井下采场、巷道掘进、天井掘进3个工作面空气环境质量进行安全评价。结果表明,采场工作面空气环境质量为良好...

This paper intends to establish a scientific and reasonable evaluation index system for the air environment under the uranium mine to estimate the quality of the air environment.Based on the investigation of the air environment of underground uranium mines in Guangdong Province and Liaoning Province, the evaluation index system is proposed from 4 categories: radioactive harmful gas, non-radioactive harmful gases, uranium dust,and thermal and humid environment.The index system mainly focuses on harmful substances in the mine air and heathumid environments and includes 6 indexes: radon,radon pro...
