摘要
废弃矿井煤层气(AMM)开发兼具经济及环保效益,具有重要的研究意义。基于中国知网(CNKI)和Web of Science期刊核心合集数据库,系统地检索了关于AMM研究的相关文献,分析了200篇论文的分布特征,归纳了近20年国内外关于AMM的发展现状及研究内容,探讨了AMM的研究不足及发展趋势。研究结果表明:(1)国内外AMM论文数量总体呈现上升趋势,尤其是在中国近5年论文上升趋势明显,说明AMM研究逐渐成为国际研究热点;(2)中国AMM研究较多的科研院校为中国矿业大学,其次为煤炭科学研究总院西安分院,境外研究AMM较多国家为美国、波兰、德国、英国等国,研究机构较多的为波兰的AGH University of Science Technology;(3)20年来国内外主要研究方向为AMM资源潜力评估、AMM扰动储层描述及富集规律研究、开采技术优化、气体泄漏监测、气源成因探究等方面。通过综述国内外研究成果得出采空区煤层气多动态汇集于采空区上部裂隙带;废弃矿井资源量评估方法国外主要采用下降曲线法,国内主要基于物质平衡原理和资源叠加原理形成多种评估方法;国外主要研究方向多集中于甲烷成因来源、资源评估方法的改进以及环境评估监测。最后指出AMM生物成因气贡献的确定、AMM动态富集分布规律的认识、资源量估算模型方法改进,环境风险评估,AMM开发地质—工程—环境一体化评价体系的制定是今后的重要研究趋势。
The development of abandoned mine coalbed methane(AMM)has both economic and environmental benefits,which has important research significance.Based on CNKI and the core collection database of the web of science journals,this research systematically retrieves the relevant literature on AMM research,analyzes the distribution characteristics of 200 papers,summarizes the development status and research content of AMM at home and abroad in recent 20 years,and discusses the research deficiencies and development trend of AMM.The results show that:①the number of AMM papers at home and abroad is on the rise,especially Chinese papers in recent five years,indicating that AMM research has gradually become an international research hotspot.②China s AMM research institutions are China University of Mining and Technology,followed by Xi an Branch of the General Coal Research Institute,the countries with more AMM research abroad are the United States,Poland,Germany,and Britain.and the research institutions are AGH University of Science Technology in Poland.③In the past 20 years,the main research directions at home and abroad are AMM resource potential assessment,AMM disturbance reservoir description and enrichment law research,mining technology optimization,gas leakage monitoring,and gas source genesis exploration.Through summarizing the research results at home and abroad,it is concluded that c Coalbed methane in gob is dynamically gathered in the upper fracture zone of gob;The evaluation method of abandoned mine resources mainly adopts the decline curve method in foreign countries,and a variety of evaluation methods are formed based on the principle of material balance and resource superposition principle in China;The main research directions abroad are mainly focused on the origin of methane,the improvement of resource assessment methods,and environmental assessment monitoring.Finally,it is pointed out that the determination of AMM biogenic gas contribution,the understanding of AMM dynamic enrichment distribution,the improvement of resource estimation model method,environmental risk assessment,and the formulation of AMM geological-engineering-environmental integrated evaluation system are important research trends in the future.
