摘要
煤矿瓦斯事故严重影响矿井安全生产,随着对矿井瓦斯防治的研究与探索,对于矿井瓦斯防治与瓦斯事故的处理也更加成熟。为了防治矿井瓦斯突涌事故,采用瓦斯抽采技术防治矿井瓦斯积聚。本文根据李村煤矿1303工作面瓦斯涌出量,提出相应的瓦斯防治措施,矿井开采深度增加导致煤层的透气性变差,从而影响矿井瓦斯抽采效率,针对这种情况对煤层低渗透性瓦斯抽采技术进行研究,并总结低渗透性煤层瓦斯抽采技术,为后续工程提供借鉴。
Mine gas accidents seriously affects safe mining.With the research and exploration of mine gas prevention and control,the treatment of mine gas prevention and gas accidents is getting more mature.In order to prevent mine gas surge accidents,gas drainage technology was adopted to prevent mine gas accumulation.Through the gas emission from the 1303 working face of Licun Mine,the corresponding gas prevention measures were proposed.The increased mining depth of the mine led to the deterioration of the permeability of the coal seam,which affected the gas drainage efficiency of the mine.In this case,the low permeability gas drainage technology of the coal seam was studied,and the gas drainage technology of the low permeability coal seam was summarized to provide reference for the follow-up project.
