摘　　要：基于鑫龙煤业红岭煤矿中硬较薄厚煤层15141超短孤岛轻放面的开采条件,采用圆图压力自计仪,连续记录轻型放顶煤液压支架的工作阻力,分析了支架工作阻力的循环变化规律,以及工作面沿面长方向的压力分布特征。Based on the mining conditions of No.15141 extra short and isolated caving mining face with light supports in medium-hard and thinner-thick seam in Hongling Coal Mine of Xin- long Mining Group, the working resistances of light hydraulic caving supports were continuously recorded by using circular pressure self-recording instrument, the cyclic change rule of supporting resistance and pressure distribution characteristics along the dip direction of working face were analyzed.

关 键 词：中硬厚煤层 孤岛工作面 放顶煤工作面 轻型液压支架 矿压显现规律 支架适应性
