薄煤层液压支架的分析与研究

Study on hydraulic supports used on thin coal seam

分析我国现有几种薄煤层液压支架架型,从整体性能、可靠性及经济性三个方面比较了二柱掩护式及四柱支撑掩护式液压支架,并为今后薄煤层支架设计提出改进方案,使之能更适应薄煤层的开采。

The paper analyzed several types of hydraulic supports used on the thin coal seam in China, and contrasted the two-leg shield hydraulic support and four-leg standing shield hydraulic support in performance, reliability and economy. It also proposed improvement schemes for the future design of supports used on thin coal seam, so as to make the support be more suitable for mining of thin coal seam.
