Simulation Study on Diffusion Area of Gaseous Pollutants Released from Coalfield Fire

  • 摘要: 为了研究煤火释放出的SO2、CO的影响区域,选取乌达煤田火区为研究对象,利用高斯烟羽模型对煤自燃释放气体的影响范围和浓度分布进行模拟计算。结果表明:有害气体主要沿着下风向扩散,并且风速越大,同一地点有害气体的浓度越低,风速对气体有一定的稀释作用。同时根据不同位置气体的浓度和《环境空气质量标准》得到达到国家不同标准时最多燃烧点个数。在治理火灾时,应严格控制燃烧点的个数,使空气质量在合理的范围内。
    Abstract: In order to study the diffusion range of SO2, CO released by coal fire, selecting Wuda coalfield fire area as the study object, we use Gaussian plume model to simulate the scope and concentration of release gas by coal spontaneous combustion. The study indicates that poisonous gas mainly diffuses down the wind, and the higher the wind speed, the lower the concentration of harmful gases in the same place; wind can dilute the gas. At the same time, according to the concentration in different locations and the "ambient air quality standards", we get the maximum number of burning points under different standards in our country. In the governance of fire, the number of combustion points should be strictly controlled to make the air quality in a reasonable range.
