中文摘要：

研究表明，弱变形脆性系列构造煤发育区往往是煤层气开发的有利区，而韧性变形的糜棱煤分布区则是矿井瓦斯突出的危险地带。因此，面向煤层气勘探与开发和瓦斯突出预测与评价是学科领域亟待解决的关键科学问题及技术难题，构造煤的研究日益受到人们的高度重视。较为系统地阐述了构造煤的概念与分类，不同类型构造煤的变形特征、孔一裂隙结构和化学结构研究方面的主要进展，指出构造煤韧性变形机制研究还十分薄弱，是有待深入研究的关键科学问题；煤变形过程中元素的迁移与聚集的构造一地球化学过程是值得探讨的新领域，有可能通过应力敏感元素的提炼，揭示其在不同应力一应变环境和不同类型构造煤中的分布和演化规律，从而成为构造煤分布和瓦斯突出具有指示意义的预测指标；不同类型构造煤和瓦斯富集区的地球物理响应特征及探测理论和解释方法研究应为未来重要的发展方向。

英文摘要：

A number of studies have shown that development areas of weak deformation brittle series of tectonically deformed coal are often the favorable areas for coalbed methane development, and the distribution area of the mylonitic coal of ductile deformation is a danger zone of mine gas outburst. Therefore, faced with solving the key scientific issues and technical problems of the coal bed methane exploration and development and gas outburst prediction and evaluation, more and more attention has been paid to the research on tectonically deformed coal. This paper first systematically elaborated the main research progress on the concept and classification of tectonically deformed coals, their deformation characteristics, and the pore fissure structure and chemical structure. Then, it pointed out that there was a lack of research on the ductile deformation mechanism of coal, and this key scientific problem needs further research in the future. It seemed that the structural and geochemical process of chemical elements migration and accumulation during coal deformation was a new field which is worth exploring. Through refining stress sensitive elements, their distribution and evolution patterns in different stress-strain environments and different types of teetonically deformed coals might be revealed, and then they could become a predictive index which indicates the significance of distribution of tectonically deformed coals and gas outburst prediction. It was thought that geophysical response characteristics and research of detection theory and interpretation method of different types of tectonically deformed coal and gas enrichment area should be an important development direction in the future.
