摘　　要：以神木张家峁煤矿5^(-2)煤层12501首采工作面为地质原型,采用理论分析和物理相似模拟手段相结合,对大采高工作面支架关键参数进行了研究分析。结果表明:ZY12000/28/63D型掩护式液压支架可较好地适用于浅埋坚硬煤层大采高开采条件,国产大采高装备技术性能等各项指标均满足首采面安全持续开采需求。The first mining face 12501 of 5^-2 coal seam in Shenmu Zhangjiamao mine is the geological prototype, using the combination of theoretical analysis and physical similarity simulation, the key parameters of large mining working face support are analyzed. The results show that the application of ZY12000/28/63 D type hydraulic shield support can be used in shallow hard coal seam with large mining height mining conditions, domestic large mining equipment technical indicators are high performance to meet the needs of first mining face safety mining.
