通过分析开元煤矿9804工作面初采期瓦斯涌出规律,为开采9801工作面提出了初采期瓦斯治理与抽采新方案:在9801工作面顶板内布置“Π”形高抽巷抽采上邻近层的卸压瓦斯,有效的解决了开元矿9801工作面初采期瓦斯治理的问题,为矿井制定控制瓦斯灾害、提高回采工作面瓦斯抽采率的技术措施提供参考依据。
By analyzing the regularity of gas emission during the initial mining period of 9804 working face of Kaiyuan Coal Mine, a new scheme of gas treatment and pumping at the initial mining stage was put forward for the mining of 9801 working face: the “Π ” shaped pumping tunnel was arranged in the roof of 9801 working face Releasing the pressure relief gas in the adjacent layer effectively solved the problem of gas treatment in the initial mining period of 9801 in Kaiyuan Mine and provided reference for mine to make technical measures to control gas disasters and improve gas drainage rate in mining face.
