我国深部煤与瓦斯共采战略思考

我国是世界上瓦斯灾害最严重的国家之一,煤炭资源禀赋与长期的旺盛需求导致我国煤炭开发以每年10~25 m的速度快速向深部转移,深部煤炭开采面临的瓦斯问题更加严峻,从安全、能源、环保3个方面考虑,都需要加大深部煤层煤与瓦斯共采力度。分析了我国深部煤层煤与瓦斯共采现状与面临的问题,指出了我国深部煤层煤与瓦斯共采发展对策,认为我国深部煤层应坚持地面和井下相结合的"两条腿走路"的煤与瓦斯共采模式,从基础理论研究、关键技术及装备研发、示范工程建设、政策扶持等方面提高深部煤层煤与瓦斯共采技术整体水平。

Strategic thinking of simultaneous exploitation of coal and gas in deep mining

China is one of the countries which are mostly affected by gas disasters.The coal exploitation rapidly transfers to deep part at the speed of 10-25 m a year for China’s coal resources endowment and long-term demand.Deep coal mining faces more serious gas problem.From the safety,energy,environmental considerations,the research on deep coal mining has been strengthened.This paper analyzes the current situations and problems of simultaneous exploitation of coal and gas in China.The direction of simultaneous exploitation of coal and gas is pointed out.China’s coal bed methane (CBM) development should stick to the ground and underground combined mode of “walking on two legs”,and improve the overall level of deep coal seam simultaneous exploitation of coal and gas technologies from the basic theory research,key technology and equipment development,demonstration project construction,policy support,etc.
