摘　　要：煤层气作为新兴的清洁能源,带来巨大的经济效益同时,可能引起一系列环境地质问题。在充分收集地质环境背景的基础上,开展鄂东石楼北煤层气区块地质环境调查和综合研究。研究发现,主要环境问题为煤层气开采造成局部含水层疏干,未来场站对周边地形地貌影响破坏严重;井场、未来输气管线及进场道路对周边地形地貌影响与土地损毁,煤层气开采对含水层结构影响较严重;划分为1个重点防治区和4个防治亚区;针对不同的土地类型实施合适的工程、生物和化学及监测措施,恢复土地的原有功能,以期为井下煤层气开采提供生产、修复和保护的理论依据。As a new clean energy,coalbed methane brings great economic benefits and may cause a series of environmental geological problems.On the basis of fully collecting the geological environment background,the geological environment investigation and comprehensive research of Shilou North coalbed methane block in the east Ordos Basin were carried out.It was found that the main environmental problem is the drainage of local aquifer caused by coalbed methane mining,and the station will have a serious impact on the surrounding landform in the future.The well pad,future gas transmission pipeline and access road have a great impact on the surrounding landform and land damage,and the exploitation of coalbed methane has a serious impact on the aquifer structure.It is divided into 1 key prevention and control area and 4 prevention and control sub areas.Implement appropriate engineering,biological,chemical and monitoring measures for different land types to restore the original function of the land,in order to provide a theoretical basis for production,restoration and protection for underground coalbed methane mining.
