摘　　要：针对6上浅埋煤层放顶煤开采的特点,通过经验类比、理论计算以及数值模拟等多种方法,对液压支架选型进行了分析论证,最终确定为ZF10000/27/42型液压支架,并通过实测矿压数据绘制工作阻力频率分布直方图,证明了该型液压支架可以满足浅埋煤层顶板控制的适用要求。According to the characteristics of top coal caving in No.6up shallow depth seam, using experience analogy, theoretical calculations, numerical simulation, and like the methods, to study and analyze the rational hydraulic support, finally adopted the ZF10000/27/42 type hydraulic support, which is confirmed to meet the applicable requirements of roof control in shallow depth seam by the frequency distribution histograms based on mineral pressure observation.
