煤田火区气态污染物扩散影响区域模拟研究
Simulation Study on Diffusion Area of Gaseous Pollutants Released from Coalfield Fire
摘要
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.关键词
