煤与瓦斯共采技术的研究现状及其应用发展

Present Situation, Application, and Development of Simultaneous Extraction of Coal and Gas

论述了煤与瓦斯共采技术的重要性及其对煤矿绿色开采的意义,介绍了煤与瓦斯共采技术的研究现状及面临的新问题,并阐明了其理论依据.分析了煤与瓦斯共采在煤矿井下的成功经验,并举例说明了井下瓦斯抽放与地面煤层气开发有机结合的重要性.最后指出了煤与瓦斯共采应注意的问题以及今后的研究方向.

The importance of simultaneous extraction of coal and gas and its purport to green exploitation are discussed. The present situation and the theory of this technique as well a some new problems are introduced. Experience of simultaneous extraction of coal and gas in coal mine is analyzed and an example is used to explain the significance of the organic combination of gas drawing underground with coalbed methan exploiting on ground surface. Finally, problems we should pay attention to and the developing way of simultaneous extraction of coal and gas are pointed out.
