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 the 15141 ultra-short island light-weight surface in middle-hard and thinner thick coal seam of Hongling Coal Mine of Xinlong Coal Mine, the working resistance of light caving hydraulic support was recorded continuously using the chart self-measuring instrument. The working resistance of the support Cyclic variation law and pressure distribution along the length of the working face.
