摘要
为揭示矿山运输道路两侧的颗粒物无组织排放规律,采用ADMS 4.0模型对某金属矿山矿物运输过程中道路两侧的颗粒物沉降速率进行了模拟。模拟结果表明:在较为温和的气象条件下(稳定度为D),道路运输产生的颗粒物影响范围最大。下风向颗粒物的沉积速率随着距离的增加而呈现先上升后下降的变化趋势。在不稳定的气象条件下(稳定度为A),道路运输的颗粒物最大沉积速率出现在下风向200 m处。
In order to reveal the law of fugitive particles emission from haulage road in a metal mine,the ADMS( atmospheric dispersion management system) 4. 0 model was adopted to simulate the deposition rate of fugitive particles emission. The results show that the influence area of fugitive particles emissions from mine haulage road is the largest one under the relatively stable meteorological condition( class D). In addition,the deposition rate of fugitive particles emission increases with the distance off the downwind direction from the road firstly,and then it decreases with the distance. Under the most unstable meteorological condition( class A),the deposition rate reaches the highest value at 200 m from the road in the downwind direction.
