摘要
根据锦瑞矿煤层的地质条件,确定液压支架的工作阻力、高度等参数,介绍了ZY6800/21/43D掩护式液压支架的结构组成、适用范围和技术参数等,对顶梁、掩护梁、底座等结构进行阐述,尤其是对过渡架顶梁侧翻板结构进行了特殊介绍。
According to the geological conditions of the coal seam in Jinrui Coal Mine, the parameters such as working resistance and height of the hydraulic support have been determined, the structure composition, application scope and technical parameters of shield hydraulic support ZY6800/21/43D have been introduced. The top beam, shield beam, base and other structures have been described in detail, especially the overturning plate structure of top beam on transition frame.
