摘要
通过对淮南矿区瓦斯治理的分析,阐述了汇集瓦斯抽放巷在矿井瓦斯综合治理和“煤与气共采”两方面中的重要意义,讨论了汇集瓦斯抽放巷的优势和具体应用、在抽放巷内进行钻场和钻孔综合施工的技术要求以及在选用汇集瓦斯抽放巷时需要注意的问题。
Through the analysis on the control and administration of gas, this article explores the significance of abstracting tunnel on gas suction in areas of comprehensive control and administration of gas in mines and ＂simultaneous - extraction of coal and coal - bed methane＂. The advantages and application of abstraction tunnel over other tunnels, the technical requirements of field - drilling and hole - drilling inside the tunnel and the problems which are worthy of attention in choosing abstraction tunnel are also discussed in this article.
