摘　　要：自移式气垛支架能根据不同的地质状况,将气垛支架作为薄煤层工作面的基本支护设备,提供相应的气垛支护工艺。自移式气垛支架是在原气垛支架基础上增加了自移装置,在充分利用气垛支架初撑力高、整体性好、伸缩比大、抗横向冲击载荷能力强、对顶底板比压低、稳定性高等特点的基础上,很好地解决了围岩控制的难题。Auto-shift-type air cushion support can be used as the basic support equipment for the working face of thin coal seam and provides corresponding air cushion support technique according different geological condition.Auto-shift-type air cushion support is to add auto-shift device to original air cushion support,and it solves the diffcult problem of surrounding rock control based on making full use of the characteristics of air cushion support such as high first support force,good integrity,large magnification ratio,strong transverse impact load resistance ability,low top floor specific pressure and high stability.
