综放工作面液压支架合理选型分析

Analysis on Reasonable Selection of Hydraulic Support in Fully Mechanized Caving Face

针对长平矿5302工作面具体情况,综合考虑煤层、顶板、底板、埋深、瓦斯、通风、技术和经济等各项因素影响,利用经验估算法、理论分析法和工程类比法分别对该矿液压支架架型选择、工作阻力、支护高度进行分析,最终选用ZF11000/20.5/38D型四柱支撑掩护式液压支架。

According to the specific situation of No. 5302 working face in Changping Coal Mine, the influences of various factors such as coal seam, roof, floor, buried depth, gas, ventilation, technology and economy were comprehensively considered. The empirical estimation method, theoretical analysis method and engineering analogy method were used to analyze the type selection, working resistance and support height of the hydraulic support in the mine. Finally, ZF11000/20.5/38D four-column support shield hydraulic support was selected.
