【摘要】 通过应用东北大学岩石破裂与失稳研究中心开发的程序模拟巷道在侧向压力作用下的破坏过程,了解了巷道围岩在侧向压力作用下围岩应力分布状态和围岩非线性渐进破坏机理。这对于调整矿体回采顺序,选择安全合理的支护方案以及改善围岩应力分布状态,提供了一定的科学依据。更多还原

【Abstract】 The progressive process of roadway wall rock failure caused by lateral pressure was simulated by using RFPA2D program developed by Center for Rock Instability and Seismicity Research of Northeastern University. The stress distribution of the wall rock and the mechanism of its nonlinear progressive failure under lateral pressure were studied and understood, providing some scientific basis for regulating the extraction sequency, selecting a safe and rational support scheme and improving the stress distribution state of wall rock.更多还原
