摘要
针对突出矿井消突增效的技术难题,通过探索运用"一面六巷"开采布置方式及立体式抽采瓦斯治理技术,提高了打钻的速度、精准度及抽采效果,缓解了接替紧张的局面;该技术提高了钻孔施工工效及瓦斯抽采效率,有效消除了瓦斯抽采"空白带",破解了单一突出工作面回采效率低的技术难题。
Aiming at the outburst - elimination and efficiency - enhancing in outburst coal mine, a gas control scheme was proposed, with arrangement of six roadways in one working face and three - dimensional drainage, the drilling speed, accuracy and drainage effect were improved, the tense situation of replacement was alleviated; the efficiency of drilling construction and gas drainage was enhanced, the blank zone of gas drainage was eliminated, the single outburst face mining efficiency was improved.
