Conclusion Numerical simulation software is used to carry out numerical analysis models for different coal pillar widths between strip lanes, and study the schemes for maintaining coal pillar widths in various sections, providing basis for the final determination of reasonable coal pillar widths and drawing conclusions: (1) The comparative analysis of surrounding rock stress of coal pillars with different widths between strip lanes shows that: after the excavation of strip lanes, once the width of coal pillars is less than 5 meters, the internal vertical stress of coal pillars is generally at a low level, and the peak stress is lower than the initial stress. In the engineering practice of coal mining, strip coal pillar plays an important role in carrying and supporting.	cache/ajst-29858.pdf	txt/ajst-29858.txt
