摘　　要：为了了解新疆某煤炭矿区矿井涌水中的天然放射性水平状况,分析其排放所致周围环境影响状况。通过对该矿区企业矿井涌水进行现场取样,并对采集的涌水样本进行了天然放射性核素含量分析,评估了涌水排放的所致周围环境的影响状况。结果表明:该煤炭矿区矿井涌水中天然铀、钍、226Ra的核素含量测值结果总体处于全国泉水的背景波动范围之内,涌水样品中总α、总β放射性测量结果低于《煤炭工业污染物排放标准》中总α、总β放射性排放限值要求,表明该矿区矿井涌水的放射性排放不会对周围环境产生放射性污染,不需要采取进一步的废水处理措施,但企业应加强对液态放射性污染物排放的定期监控工作。In order to understand the natural radioactivity level in the mine water of a coal mining area in Xinjiang, the environmental impact caused by its discharge was analyzed. Through on-site sampling of the mine water inflow of the mining enterprises, the natural radionuclide content of the collected water inflow samples was analyzed, and the impact of the water inflow discharge on the surrounding environment was evaluated. The results show that: the measurement results of natural uranium, thorium and 226Ra radionuclide content in the mine water of the coal mining area are generally within the background fluctuation range of the national spring water, and the measurement results of total α and total β radioactivity in the water samples are lower than the requirements of total α and total β radioactivity emission limits in the emission standard of pollutants for coal industry, which indicates that the radioactive emission of the mine water will not affect the surrounding environment There is no need to take further wastewater treatment measures for radioactive pollution in the environment, but enterprises should strengthen the regular monitoring of liquid radioactive pollutant discharge.
