本煤层瓦斯抽放技术途径及分析

Recently years, the existing technology and equipment of gas disaster prevention have been unable to effectively control anomalies emission of coal seam and gas with the improvement of mine’s mechanization level and production intensification. Coal gas flow theories at home and abroad and common technology methods of gas drainage in seam were introduced, the existing problems in technology methods of gas drainage in seam were analyzed by the combination of Coal gas flow theories with technology methods of gas drainage in seam, proposing the solution and methods based on this, which was useful to direct the gas control and the safe production in the future.
