【摘要】 文中以地质动力区划方法查明的各级活动断裂为区域构造格架，将矿区简化成由２７条断裂的弹塑性平面模型。经过数值模拟计算，得出了１－２断裂所形成的构造应力区是北票矿区煤与瓦斯突出的主要成因，是矿区动力现象显现的动力源的结论更多还原

【Abstract】 This paper views free faults discovered by geodynamic division as regional tectonic framework. It simplifies the mine into an elastic plan model with 27 faults and designs calculation stress software. It concludes by calculation: The main cause of outburst of coal and gas is tectonic stress region formed by fault I, dynamic phenominon in the mine show the dynamic source.更多还原
