摘要
通过对四柱支撑式放顶煤液压支架存在问题的分析和两柱掩护式液压支架对煤层条件的良好适应性,经过大量的分析和论证,设计了两柱掩护式低位放顶煤液压支架,该型液压支架的设计和开发,为放顶煤液压支架的推广和应用提供了广阔的前景。
By analyzing the questions showed in four-leg shock top-cave support,considering the better adaption of two-leg shield support for coal seam conditions,after a mount of demonstration,I design this two-leg low-position shield top-caving support,which is a new kind and further opens a new adaption situation for hydraulic support.
