摘要
煤与瓦斯突出倾向与煤层的变质变形历史有关。煤层的变质变形演化大致有３种基本模式：变质－变形模式；同变形变质模式：变形－变质模式。具有第１种演化模式的煤层突出危险性较小，而具有第２、３种模式的煤层突出程度较高。
Outbursts of coal and gas prone is related to the evolution history of deformation and coalification of coal-seams. Coal-seams could be classed as three basic models by their evolu-tion histories:coalification-deformation, simultaneous coalification-deformation and deformation-coalification model.The later two models might be more violent prone.Gas-geo-logical history analyzing will make better forecasting outbursts of coal and gas and be also signif-icant for gas geology developing.
