摘要
为了解决坚硬顶板瓦斯超限的问题,本文以东曲矿18311工作面为研究背景,通过数值模拟并结合现场实践对矿井瓦斯治理进行研究,模拟确定瓦斯在巷道的分布规律,利用高位钻孔对瓦斯进行抽排,经过现场实践验证了方案的可行性及优越性,为矿井高效、安全开采做出一定的贡献。
In order to solve the problem of over-limiting gas in hard roof,18311 working face of Dongqu mine was taken as the research background,the gas management in mine through numerical simulation combined with field practice was studied,the distribution law of gas in the tunnel through simulation was determined,high drilling was adopted to extract gas,and the feasibility and superiority of the scheme was verified through field practice,which made some contribution to the efficient and safe mining.
