摘 要:本文主要介绍鸡西矿区东海煤矿火成岩侵入采煤工作面,在透气性低煤层采煤工作面采取高位钻场近水平抽采、工作面上隅角抽采和煤层注水等瓦斯综合治理方面的技术和方法。实践证明,通过矿井瓦斯抽采的有效工作,使矿井的通风管理、瓦斯治理工作有了稳步提高,矿井安全可靠度增强。The paper chiefly describes techniques and methods applied for control of gas in a coal face with intrusion of igneous rock in Donghai coal mine in Jixi coal mining area. There are included gas drainage from a coal face in low permeability seam by drilling of near-horizontal boreholes from drill site in the overlying roadway, gas drainage from upper comer of work face and water infusion of coal seam. The practical experiences have proved that the mine ventilation management and gas control work have steadily improved and reliability of mine safety has been enhanced through effective gas drainage.
