摘要
在RFPA2D-FLOW软件基础上,利用倾角30°、60°的断层力学模型,分别对宁东煤田2#煤采掘工作面的开挖过程进行了数值模拟,模拟出断层及断层两盘岩体受力和破坏的动态变化,分析出2#煤顶、底板岩层及断层在断层活化过程中应力特征和破坏状态的变化规律。
On the basis of RFPA2D-FLOW software, numerical simulation of mechanical model of fault with dip 30°and 60°was carried out respectively for the mining process of No.2 coal seam heading wining faces in Ningdong coal field, showing the dynamic changes on stress and failure of fault cross-fauh rock mass,and drawing the conclusion on the changes rule of stress characteristic failure state in fault activation process. and and and
