U形通风方式下瓦斯浓度分布规律研究

Study on the Distribution Law of Gas Concentration under U-Shaped Ventilation Mode

以某煤矿工作面为研究对象,利用ICEM CFD软件对工作面进行建模,并利用FLUENT软件对该工作面在U形通风情况下,采空区未抽采时的瓦斯浓度进行模拟,分析瓦斯分布规律,以此为基础制定抽采方案,进而确保煤矿开采的安全性和经济性。

Taking the working face of a coal mine as the research object,ICEM CFD software is used to model the working face,and FLUENT software is used to simulate the gas concentration of the working face under U-type ventilation when the mining airspace is not extracted,and then analyze the distribution law of gas to formulate the extraction plan based on it,and thus to ensure the safety and economy of coal mining.
