摘要
本文根据2305切眼/调车巷与23062/64封闭巷道贯通及瓦斯排放存在的问题,分析现场条件,确定施工方案,通过采用施工Ф400mm的大直径钻孔渐进式贯通,局部通风、全风压通风、抽放三种综合措施排放封闭区、高浓度、复杂巷道内瓦斯,实现了安全生产,为今后的封闭区域巷道贯通及排放瓦斯提供了经验。
Based on the existing problems of linking the 2305 shunting Lane and/23062/64 closed lane and the gas emissions, the author analyzed site conditions to determine the construction plan. By using large diameter drill hole of ＋400mm and by taking three comprehensive measures of partventilation, full air pressure ventilation and drainage to discharge the high concentration gas in the complex region, the work safety can be realized. This provided the experience for linking the lanes of closed area and the emission of gas in the future.
