摘要:
煤与瓦斯共采技术是煤矿绿色开采技术的重要组成部分之一。针对矿井煤层薄、煤层透气性低、煤层瓦斯含量低等特点，应用岩层移动理论和采空区瓦斯流动规律，研究了采场内卸压瓦斯的运移路径和富集区域，建立了矿井煤与瓦斯共采系统，采用了高位顶板穿层钻孔瓦斯抽采方法和老采空区瓦斯抽采方法等综合瓦斯抽采方法，降低了矿井瓦斯涌出量，消除了工作面瓦斯积聚现象，提高了矿井瓦斯抽采率和抽采浓度。在保障煤炭资源安全开采的前提下实现了瓦斯资源的安全、高效抽采
Abstract:
Technology of simultaneous coal mining and gas drainage is one of green mining technologies in coal mine. Aiming at the characteristing thin seam, poor gas permeability and low gas content in thin seams in Laoyingyan mine, the migration paths and abundant region of pressurerelieved gas from gob were studied by means of the strata displacement theory and gas movement regularity from gob. Simultaneous production system of coal mining and gas drainage was established in the mine, and thecombined gas drainage method was adopted. The mine gas emission was reduced, the phenomenon of gas concentration in the working face was eliminated, and the mine gas drainage efficiency and drainage concentration were improved. The gas resource was safely and efficiently drained under the premise of safe mining on coal resources.
