提高煤矿区煤层气利用率的科技方向研究

Research on the scientific and technological direction of improving the utilization ratio of coal mine methane

提高煤矿区煤层气利用率是增加清洁能源供给、推进生态文明建设、推动产业发展的现实选择。近年来,尽管煤矿区煤层气抽采利用量大幅提高,但仍面临抽采利用率不高困境,存在抽采浓度低、抽采量和浓度不稳定、关键技术待攻关、经济效益差等难题。结合国内外煤矿区煤层气科技发展趋势,分析了理论提高煤矿区煤层气利用率面临多重难题,并从地面采动高效优质抽采、井下智能提浓高效抽采、全尺度浓度梯级利用等方面提出提高煤矿区煤层气利用率的未来科技方向。

Improving the utilization rate of coal mine methane is the realistic choice to increase the supply of clean energy,promote the construction of ecological civilization and promote the development of industry.Although coal mine methane extraction and utilization has been greatly improved in recent years,it still faces difficulties in extraction utilization,and there are problems such as low extraction concentration,unstable extraction and concentration,key technologies to be tackled,and poor economic returns.Combining with the development trend of coal mine methane technology at home and abroad,the multiple problems of improving the utilization rate of coal mine methane by theory.From the aspects of high-efficiency and high-quality extraction from the ground,intelligent and efficient extraction under the well,and full-scale concentration cascade utilization,the future scientific and technological direction were proposed to improve the utilization rate of coal mine methane.
