摘要
通过对某煤矿 25703 综采工作面内部瓦斯实际分布情况分析,基于数值模拟和生产经验提出煤层预抽采、高抽巷抽采、高位钻孔以及采空区埋管等综合瓦斯治理方式,并在实际生产当中应用验证瓦斯综合治理技术效果.
Abstract
Through the analysis of the actual distribution of gas inside the 25703 fully mechanized mining face of a certain coal mine,based on numerical simulation and production experience,comprehensive gas control methods such as coal seam pre extraction,high extraction roadway extraction,high-level drilling,and goaf buried pipes are proposed,and the effectiveness of gas comprehensive control technology is verified in actual production.
