摘要
以莒山矿 3 盘区 3305 工作面为研究对象,在分析工作面瓦斯来源、瓦斯涌出量主要影响因素、瓦斯涌出量及矿井瓦斯抽采系统的基础上,提出了 3 号煤层工作面采用钻孔预抽煤层瓦斯的抽采技术和具体的瓦斯抽放方法,分析了工作面钻孔布置方式及瓦斯抽放量,并对瓦斯抽放情况进行评价,在此基础上给出了瓦斯抽采安全技术措施.
Abstract
Taking the 3305 working face in Zone 3 of Jushan Coal Mine as the research object,based on the analysis of the gas source,main influencing factors of gas emission,gas emission amount and mine gas extraction system,this paper proposes a drilling pre-extraction coal seam gas extraction technology and specific gas extraction method for the No.3 coal seam working face.The drilling layout and gas extraction amount of the working face are analyzed,and the gas extraction situation is evaluated.On this basis,safety technical measures for gas extraction are provided.
