摘要
对目前国内广泛应用的井下瓦斯抽采、地面钻井瓦斯抽采技术进行了总结和概述,分析其优缺点,并在此基础上分析介绍了国内外一些优秀研究成果,提出高压脉冲水射流及定向水力压裂技术、N2/CO2-ECBM技术、大孔径超长定向钻孔技术及CH4氧化菌微生物技术等瓦斯抽采新技术。
The papermainly deals with the current applied widely techniques at home: drilling techniquesand surface techniquesof gas drainage,the advantages and disadvantages of them are summarized andanalyzed. And based on these, some outstanding research results at home andabroad are introduced,the technologyof high pressure pulse water jet cutting in coal seam and oriented hydraulic fracturing,N2/CO2-ECBM technology, long directional drilling of large diameter technology, methanedegradation bacterium technology and so on are putforward.
