通过对新疆某典型煤矿矿井排风巷道口附近氡浓度调查与测量，构建模型，运用UAIR-FINE软件模拟煤矿析出的氡排放所致周围20 km范围内各子区的附加氡浓度分布和公众年附加有效剂量分布。结果表明，煤矿矿井析出氡排放所致周围20 km范围内附加氡浓度最大值出现在矿井排风井周围，贡献值在0.05 Bq/m3左右，远低于我国室外空气中平均氡浓度14.0 Bq/m3，几乎对室外空气氡浓度没有贡献，也不可能对矿区周围环境敏感点–居民点(村庄)的居室环境中氡浓度产生较大贡献。在矿井正常生产1年、10年、60年情况下，环境敏感度点处(A村、B村、D村、E村)的公众最大年附加有效剂量在0.01 mSv/a左右，矿井析出氡的排放对周围20 km范围内公众的影响较小，在可接受的范围之内。
Based on the investigation and measurement of radon concentration near the ventilation gateway of a typical coal mine in Xinjiang, the model was constructed, and the additional radon concentra-tion distribution and annual additional effective dose distribution of the public in each sub area with- in 20 km caused by the radon emission from coal mine were simulated by UAIR-FINE software. The results show that the maximum value of additional radon concentration within 20 km caused by radon emission from coal mine occurs around the mine ventilation shaft, and the contribution value was about 0.05 Bq/m3, which was far lower than the outdoor air average radon concentration of 14.0 Bq/m3 in China, and almost has no contribution to the outdoor air radon concentration. It was also impossible to make a greater contribution to the radon concentration in the residential environment of the sensitive point (village) around the mining area. Under the condition of normal production for 1 year, 10 years and 60 years, the maximum annual additional effective dose of the public at the environmental sensitive points (village A, village B, village D and village E) is about 0.01 mSv/a, and the impact of radon emission from the mine on the public within 20 km is small and acceptable.
