摘要
基于动压条件下软岩巷道围岩变形机理等相关理论,借助岩石力学实验、FLAC3D数值模拟,对龙口梁家煤矿六采区4600工作面下顺槽沿空掘巷围岩失稳机制进行了系统研究。结果表明:深部高应力、围岩低承载能力以及动压的影响是工作面下顺槽围岩失稳的主要原因。
Based on the deformation mechanism of surrounding rock under dynamic pressure,the methods of rock mechanical testis condected by using the numerical simulation by FLAC3 Dto study on the deformation mechanism of surrounding rock in roadway driving along next goaf in six mining district 4600 working face of Liangjia coal mine in Longkou. The results showe that,deep high stress,low bearing capacity of surrounding rock and effect of dynamic pressure are proved to be the main reasons of roadway failure.
