摘　　要：本文介绍了轻放支架在残采孤岛工作面高应力区域的应用情况,通过矿山压力观测,分析轻放工作面液压支架支护阻力的循环变化规律,工作面沿倾斜方向上的压力分布特征。通过技术经济效益分析,得出了轻放支架应用效果好。研究结果表明,工作面轻放支架支护参数合理,具有良好的适应性,应用于边角煤柱回收,具有安全可靠、煤炭回收率高、经济效益好的特点。为轻放支架在类似条件下推广应用提供了经验。The paper introduces application of light-duty caving Support in remaining coal mining and isolated island working face. The circle change rule of supporting resistance and pressure distribution characteristic on trend of light-duty caving face were analyzed by rock pressure observation. Application effect of light-duty caving support is best by techno-economic benefits analysis. Supporting parameters are suitable for the working face, indicating that there have some particular characteristics in light-duty caving remaining coal mining and isolated island working face, such as ① on the safe side at reclaiming abnormity coal column, ② higher rate of recovery of coal, ③ best techno-economic benefits. The study results provide experience of light-duty caving support application in the same condition.
