摘要
针对隆博煤矿综采工作面瓦斯涌出量大,影响工作面安全开采的问题,通过分析工作面瓦斯来源,确定了高位钻孔抽采和采空区埋管抽采相结合的工作面瓦斯治理方案。由5009综采工作面试验可知,工作面内瓦斯监测点均没有瓦斯含量超标显现,上隅角瓦斯体积分数始终保持在0.5%以下,保障了工作面的生产安全。
In view of the large gas emission from the fully-mechanized mining face of Longbo Coal Mine,which affects the safe mining of the working face,through analyzing the gas source of the working face,a gas control scheme combining the high-level drilling drainage and the buried pipe drainage in goaf was determined.The test in 5009 fully-mechanized mining face showed that the gas content in the gas monitoring points in the working face didn't exceed the standard,and the gas volume fraction in the upper corner was always kept below 0.5%,ensuring the safe production of the working face.
