摘　　要：【目的】分析煤层气抽采各污染物产生环节及其环境影响,提出煤层气开发过程中的环境保护措施。【方法】通过对河南省煤矿瓦斯治理及开发利用情况进行实地调查,并结合山西、陕西等地的产业开发经验,对煤层气开发过程的环境影响进行分析。【结果】煤层气开发建井及生产运营期钻井和管道施工过程会压占土地,破坏植被,影响土地功能;排水采气过程可能会使区域地下水补给、排泄和径流条件发生变化,从而引起区域地下水位下降和地下含水层污染。同时该时期会对大气、土壤、水环境、声环境等造成影响。退役井场不再进行作业,区域生态系统功能逐渐恢复,但仍可能造成一定影响。【结论】煤层气开发过程应合理规划、利用和施工,尽量减少对生态环境的影响。研究结果有助于推动我国煤层气产业高质量发展。[Purposes]This paper analyzes the production link of pollutants and their environmental impact in coal-bed methane(CBM)mining process,and then puts forward the corresponding environmental protection measures.[Methods]Through the field survey of coal mine gas control and development and utilization in Henan Province,and combined with the industrial development experience of Shanxi and Shaanxi Provinces,the environmental impact of CBM mining process is analyzed.[Findings]Well drilling and pipeline laying process of underground mine construction and operation period of CBM mining will take up land,destroy vegetation and affect land function;the drainage and gas extraction process may change the regional groundwater recharge,discharge and runoff conditions,thus causing the decline of groundwater level and underground aquifer pollution.At the same time,this period will case air pollution,water pollution,solid waste pollution,noise pollution and so on.Abandoned well site will no longer operating,and the regional ecosystem function will gradually restore,but the site may still cause pollution.[Conclusions]The development process of CBM should be rationally planned,rationally utilized,rationally constructed,so as to minimize the impact on ecological environment.In addition,the research results are helpful to promote the high-quality development of China's CBM industry.
