摘要
以昌恒煤矿9101工作面为背景,进行了主采煤层9煤层顶底板岩石物理力学性质实验.运用FLAC^(3D)数值分析软件,模拟了9101工作面开采应力条件下断层尖灭部位两盘位移动态变化过程,揭示了煤层开挖掘进中由于断层构造引发的顶板裂隙的生成机制,阐述了断层对顶底板破坏随工作面推进的时空演变.分析结果为煤炭绿色开采和水害致灾机理提供了技术支持.
Based on the 9101 working face of Chang-Heng coal mine,the physical and mechanical properties of the top floor of 9 coal seam in the main mineable coal seam are studied. Using FLAC^（3D） numerical analysis software,this paper the dynamic change of two disk displacements in the fault tip-quenching area under 9101 working face mining stress,is simulated to reveal the formation mechanism of the roof fissure caused by fault structure in the excavation of coal seam,and expounds the space-time evolution of the fault to the top floor in the face of pushing. The analysis results provide important technical support for the coal green mining and disaster-causing mechanism.
