摘　　要：针对五虎山煤矿010910工作面下行通风条件下,现有瓦斯治理技术对采空区瓦斯治理不彻底,造成工作面下隅角瓦斯频繁超限的问题,在分析了工作面瓦斯涌出来源及下隅角超限原因的基础上,选取大直径钻孔抽采、高位钻孔抽采等瓦斯治理技术,解决了工作面下隅角瓦斯超限问题,确保了该工作面的安全高效回采。Under the condition of downward ventilation in 010910 working face of Wuhushan coal mine,the existing gas control technology does not completely control the gas in the goaf, resulting in frequent gas overrun in the lower corner of the working face. Based on the analysis of the gas emission source of the working face and the reasons for the overrun of the lower corner, the gas control technologies such as large diameter borehole and high level borehole are selected to solve the problem. The solution to the problem of gas overrun in the lower corner of the working face ensures the safe and efficient mining of the working face.
