摘要
煤层开采过程中,采空区附近原本的应力平衡状态会受到破坏和影响,从而区域内应力重新分布,导致岩层变形、破坏、移动,称之为工作面上覆岩层移动。基于此,结合工程实例,对岩层移动基本规律进行分析,研究采煤工作面上覆岩层移动规律模拟实验,探讨关键层运动对其的影响,总结岩层移动中的离层和裂隙分布情况。
The original stress balance was damaged and impacted near the worked out section in the process of coal mining, and regional internal stress was redistributed, which led to the rock deformation, destruction, movement, namely called as the overlying strata movement in working face. Based on this, this paper analyzed basic rule of strata movement combined with practical engineering, studied simulation experiment of the overlying strata movement rule in working face, discussed the influence of key stratum movement, and summarized delamination and fracture distribution in the strata movement.
