Practice and achievements of gas prevention system of Kailuan Group in the construction of coal mine

针对所属矿井和托管矿井为高瓦斯矿井、煤与瓦斯突出矿井和瓦斯矿井的实际情况,开滦集团公司努力构建"通风可靠、抽采达标、监测监控、管理到位"的煤矿瓦斯综合治理工作体系,推进瓦斯防治技术和管理创新,使瓦斯防治工作得到了明显加强,所属矿井有效风量率提高到87%以上,采掘工作面风量备用系数提高到1.8,瓦斯抽采率和瓦斯利用率分别由2011年的38%、16%提高到了47%、25%,有效遏制了瓦斯事故的发生,为开滦矿区的稳定和发展提供了安全保障。
