摘要
针对顾桥煤矿1114(1)孤岛工作面煤层赋存条件和生产实际,通过对工作面瓦斯来源分析及预测,因地制宜的制定合理的瓦斯综合治理方案。采用风排、顶板走向穿层钻孔、低抽巷、采空区埋管等瓦斯抽采治理技术,有效地治理了工作面的瓦斯涌出,杜绝了瓦斯超限和积聚现象,保证了综采面的正常开采。
For the coal seam occurrence condition and the actual production, based on analysis and prediction of gas source of coal face, the reasonable gas comprehensive control scheme is formulated to adapt to local conditions. Comprehensive coal gas control technology, such as ventilation air methane,the along-strike roof drills, floor gas drainage roadway, gob drainage pipe technology, effectively control the gas emission of coal face, eliminate the gas overrun and accumulation phenomenon, ensure the normal production of the fully mechanized face.
