煤的解吸规律研究现状及发展趋势

Research Status and Development Trend of Desorption Law of Coal

瓦斯是煤层中的主要气体,研究分析煤层解吸瓦斯的规律,能够有效地避免煤层开采时煤与瓦斯突出的危险。在以往的研究中,不难发现煤解吸瓦斯与煤的孔隙结构、破坏类型以及水分、灰分和挥发分有关,还与振动、压力、温度等因素有关。本文主要分析温度、振动以及孔隙结构对瓦斯解吸的影响程度,并且提出目前存在的不足,指出了煤炭解吸瓦斯的发展趋势和应用前景,并将其应用于需要解决的实际工程问题。

Gas is the main composition in coal seam.The research and analysis of the law of desorption gas in coal seam can effectively avoid the danger of coal and gas outburst in coal seam mining.In past researches,it is not difficult to find that desorption gas of coal is related to pore structure,failure type,water,ash and volatile matter of coal,and also related to vibration,pressure,temperature and other factors.This paper mainly analyzes the influence of temperature and pore structure on gas desorption,and puts forward the existing shortcomings.Meanwhile,it points out the development trend and application prospect of coal desorption gas,which is used to solve the engineering problems in the practical application.
