Abstract针对深凹露天矿的情况,建立了一个高分辨的、三维非静力的边界层模式,对某深凹露天矿实际地形及气象条件下的边界层结构进行了模拟,并与一个粒子随机游动空气质量模式相连接,对该露天矿矿区的空气质量状况进行了初步预测。结果表明,该模式具有模拟小尺度深凹地形边界层的能力,复环流区封闭、低速和高湍能的特点是造成坑内污染的重要机制。
Other AbstractIn this paper, a high-resolution, nonhydrostatic, three-dimensional ABL model for deep concave open pit mine was established to study its ABL structure under its actual terrain and meteorology conditions. The model was connected with a random walk dispersion model and the preliminary forecasting situation of the air pollution over the open pit mine was got. The results show that the model has capacity of simulating ABL of microscale deep concave terrain, and the close, low velocity and high TKE of the re-circlation are the important mechanism inducing air pollution in the pit.
