摘要
以M煤矿工作面回采巷道掘进过程为例,详细阐述煤炮现象的工作原理及发生特点,结合巷道掘进中围岩的变形及破坏情况进行数值模拟,以期对相关工作有所借鉴。
Taking the roadway tunneling at the working face of M Mine as an example, this paper elaborated the working principle and the occurrence characteristics of coal burst and carried out numerical simulation combined with the deformation of surrounding rock in roadway drivage and the damage situation in order to provide references for the related work.
