目的为伴生放射性矿山工程设计人员和辐射防护工作提出实际参考意义。方法钒矿区平峒内γ外照射和氡气现场的监测。结果钒矿区部分平峒内的氡浓度水平达到830 Bq/m3。结论钒矿部分平峒内氡浓度达到国家标准中考虑采取补救行动的要求。通过增大井下通风率(至少达到0.01min-1)和其他利益代价较小的降氡方式,可有效的降低井下氡浓度。
The purpose of this paper is to provide practical reference significance to associated radiation mine engineering designers and radiation protection work. Methods Monitoring of γ Radiation and Radon in Flat Mines of Vanadium Mining Area. As a result, the radon concentration level in some of the Pinghu mine area reached 830 Bq / m3. Conclusions Radon concentration in vanadium ore mine reaches the requirements of national standards for remedial action. Downhole radon concentration can be effectively reduced by increasing downhole ventilation rate (at least 0.01min-1) and other less-expensive radon lowering methods.
