为判断常村煤矿S5-15工作面应力集中区域，解决巷道由于高偏应力造成的变形剧烈难题，通过数值模拟，分析了特殊孤岛工作面掘巷及回采扰动下巷道存在大变形失稳破坏的关键位置，对比不同煤柱宽度高应力区域的分布，结果表明：10 m煤柱下不同回采时期的高应力集中区域不同，其重点防控区域也不同；不同煤柱下巷道上方高应力集中程度不同，随着所留煤柱的增加，高应力呈现相反的变化趋势。该研究为后续巷道围岩的重点防控提供思路。

 In order to judge the stress concentration area of No.S5-15 Face in Changcun Mine and solve the problem of severe deformation caused by high deviatoric stress in roadway, the key position of large deformation and instability failure of roadway under special island working face excavation and mining disturbance was analyzed by numerical simulation. The distribution of high stress areas with different coal pillar widths was compared, which provided ideas and theories for the key prevention and control of surrounding rock in subsequent roadways. The results showed that the high stress concentration areas in different mining periods under the 10 m coal pillar were different, and the key prevention and control areas were also different. The high stress concentration degree above the roadway under different coal pillars is different. With the increase of the remaining coal pillars, the high stress showed the opposite trend. This study provided ideas for the key prevention and control of subsequent roadway surrounding rock.
