坚硬顶板下综采工作面瓦斯治理技术研究

Study on Gas Control Technology of Fully Mechanized Mining Face under Hard Roof

以209工作面为工程背景,通过数值模拟结合现场实践对矿井瓦斯治理进行研究,通过模拟确定瓦斯在巷道分布规律,利用高位钻孔对瓦斯进行抽排,现场实践效果良好,有效解决采空区瓦斯积聚的问题。

Taking working face 209 as the engineering background,this paper studies the mine gas control through numerical simulation combined with field practice,determines the gas distribution law in the roadway through simulation,and uses high-level drilling to drain the gas.The field practice effect is good,which can effectively solve the problem of gas accumulation in goaf.
