兴隆煤矿15211工作面上隅角瓦斯治理技术研究

摘要

Based on 15211 working face in Xinglong coal mine as the object of study,according to the working face upper corner gas overrunning problem,through theoretical calculation and field measurement, this paper presents a new control of gas at upper corner angle of technical measure,the working face upper corner gas overrunning problem is effectively solved by adopting the technology and ensure the safety of production.%以兴隆煤矿15211工作面为研究对象,针对该工作面上隅角瓦斯超限问题,通过理论计算与现场实测,提出在尾巷布置抽放钻孔治理上隅角瓦斯的技术措施.采用该技术措施有效的解决了该工作面上隅角瓦斯超限问题,保证了工作面的安全生产.
