摘要
运用流体力学软件模拟某铀矿床采场氡浓度分布,其中源项数据通过数值模型获取,环境参数通过监测获取。模拟结果显示:沿着入风方向,氡浓度分布的变化以矿堆位置为临界点,呈升高、降低再升高的变化趋势。通过与监测结果对比得知,其相对误差为18.53%,产生误差的原因主要是由通风参数和环境参数变化所致。
The simulation model of radon concentration distributing in the uranium mining stope by the hydrodynamics software. The radon sources were calculated by numerical analysis method, the environment parameters were adopt by monitor date. The simulation result indicates that, along the direction of insufflate wind, the radon concentration was increasing which was under the windward of the ore pile. But under the leeward of the ore pile, the radon concentration first decreasing and then increasing. The monitor date and simulate result were compared, the relative error was 18.53%, the error were generated because of the changing parameters which include ventilate and environment parameters.
