摘　　要：本文在对南桐矿区不同煤岩组成和不同破坏程度的大量煤样进行光学显微镜和扫描电镜观测的基础上,运用岩石损伤力学和流变学理论,结合构造演化对破坏煤形成的微观机理进行了探讨,并指出了不同类型的破坏煤与煤和瓦斯突出及煤层气开采的关系。Based on observation on a large amount of coal samples of various coal petrology compositions and breakages in Nantong Mining Area under the microscope and SEM, microscopic forming mechanism of broken coal has been probed into by using rock damage mechanics and rheology and considering tectonic evolution. Relations between broken coals and coal and gas outbursts as well as coalbed methane recovery have been pointed out.
