摘　　要：通过矿山压力观测,分析了某煤矿高应力区残采孤岛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以及顶板及顶煤的活动规律。研究结果表明,工作面轻放支架支护参数合理,支架适应性良好,对高应力区应用轻放开采回收边角煤柱安全可靠。Based on pressure observation on the mine, the circular change rule of working resistance of hydraulic support on light-support caving face of residual mining area, pressure distribution along the trend of working face, the laws of top-coal and roof movement in high-stress area in one coal mine have been analyzed. Results show that the light-support for the working face has a reasonable supporting parameters and a good adaptability. It is concluded it＇s safe and reliable to use light-support caving technology to recover boundary coal pillar in high-stress mining area.
