摘要:U型通风上隅角的瓦斯治理一直是一个难题,而高抽巷的抽采能有效抽出采空区裂隙带的瓦斯,降低上隅角的
瓦斯量。但由于要提前掘进巷道,对采掘衔接紧张的矿井会构成一种负担,特提出一种高位大孔径钻孔替代高抽巷进行
瓦斯抽采治理的技术。应用该技术治理效果明显,为同类型工作面的瓦斯治理提供了借鉴。

Abstract: Gas management in the upper corner of the U-shaped ventilation has always been a problem, and the drainage of highdrainage
roadway can effectively drain the gas in the cracked zone of the goaf and reduce the amount of gas in the upper corner.
However, due to the need to excavate the roadway in advance, it will become a burden to the mines with tight connection between
mining and excavation. This paper proposed a high -location large -aperture drilling instead of high -drainage roadway for gas
drainage treatment. The treatment effect was obvious, which provided reference for gas treatment in the same type of working face.
Key words: high-location large-aperture; upper corner; U-shaped ventilation; high-drainage roadway
