摘要: 分析了沿沟煤矿“11·8”石门揭煤特大型煤与瓦斯突出并诱发底板岩层冲击地压事故,并通过煤岩体的稳定性分析和煤岩体受扰动后拉应力的计算阐述了煤与瓦斯突出诱发冲击地压的力学机理,最后对事故原因进行了分析并提出了对策。Abstract: The paper analyzes "11·8" uncovering coal in crosscut large coal and gas outburst induced rock burst accidents in floor strata of Yangou Coal Mine. Through stability analysis of coal rock and the calculation of coal rock after a disturbance stress, the paper introduced the mechanical mechanism of coal and gas outburst induced rock burst. Finally, the causes of the accidents are analyzed and countermeasures are put forward.
