摘要
煤与瓦斯突出是煤矿五大自然灾害之一,因此,瓦斯抽放工作成为当前煤矿消突的重点工作。以东欢坨矿1~3高瓦斯突出煤层为研究对象,建立了采空区垮落带瓦斯分布规律的数学模型,利用计算机仿真软件Fluent软件对该区域内的U型通风工作面进行仿真,提出了T型管网抽放和高位钻孔抽放2个立体抽放消突措施,并进行了模拟验证。
The coal and gas outburst is one of five natural disasters in coal mines. Therefore, gas drainage becomes the focus of current coal mine outburst elimination. Taking Donghuantuo Mine 1~3 high gas outburst seam as a research object, the mathematical model of gas distribution rule in the goaf caving zone is established, U type ventilation for the region’s face is simulated by using Fluent software, two cubic drainage and outburst elimination measures with T type pipe drainage and high drilling hole drainage are put forward, and simulations are carried out to verify.
