留设保护煤柱时，底板岩巷应位于集中应力区的外侧或跨采时工作面应推过足够距离，使巷道靠近采空区应力恢复区的下方。
The floor roadway should be located out of the abutment stress zone when protection coal pillar is retained, or the working face should be pushed away for enough distance under overhead mining.
研究结果表明，煤柱上支承压力分布是开采影响岩层相互作用的结果，是开采引起集中应力在煤层与直接顶界面上的直接反映。
The results show that the abutment pressure distribution on coal pillar is the direct reflection of abutment stress induced by mining on the interfaces of coal seam and immediate roof.
这些构造部位的频繁伸缩使应力集中，导致微裂纹的产生。
Constant flexing of the structure concentrates stress, which leads to microscopic cracks.
