摘　　要：我国煤层气资源丰富,但利用率不足20%,针对这一情况,通过研究发现其原因在于:一方面我国煤层透气性差,抽采率及抽采浓度低,不利于煤层气利用;另一方面我国煤层气利用技术和途径单一。提高煤层气抽采率和抽采浓度,并采用包括民用、发电、浓缩和通风煤层气利用等各种技术手段,综合利用不同浓度的煤层气,可实现煤层气资源的高效利用,并缓解对环境的排放压力。China is rich in coal-bed methane resources, but its utilization rate is less than 20%. To counter to this problem, research was carried out on its utilization and it was found out that on one hand, the lower gas extraction rate and gas extraction concentration were disadvantageous for the utilization of the coal-bed methane, and on other hand, the utilization technology and methods were single. By improving the extraction rate and extraction concentration of coal-bed methane and comprehensively utilizing the coal-bed methane in different concentration such as for civil use, electricity generation, the production of compressed methane and the utilization of ventilation air methane, the high efficient utilization of coal-bed methane resource can be realized and its pollution to the atmospheric environment can be relieved.
