摘要
本文应用有限单元法分析了不同宽高比、不同顶底极岩性条带煤柱中的应力分布，并根据计算结果给出了条带煤柱强度计算公式，以及煤柱保持长期稳定的条件。
The strees distribution in the coal pillar has been analysed by limited element methodsin this paper.The formula culculating the strength of coal pillar in patial mining and stable comditions of coal pillar have been presented.
