摘　　要：我国极薄煤层的开采机械化问题,比较突出,主要设备为采煤机。文中对极薄煤层用爬底板端面截割采煤机小直径滚筒的装煤效率,通过参数分析及一系列的实验研究,根据其有关参数对装煤量、装煤效率及比能耗的相应有利关系,提出小直径滚筒设计应该是:适宜的滚筒和筒毂直径;2～3头的光滑叶片且升角在30～35°;转速在120～130r/min的逆向旋转滚筒以及与转速相匹配的1.2～2m/min的牵引速度。Through the parameter analysis and a series of experiment and study, according to the relative beneficial relation of the parameters concerned to coal loading capacity. loading efficiency and the specific energy consumption, the article proposes that the design of the small diameter drum should be: appropriate diameters of the drum and the drum hub: two to three smooth spiral vanes and the vane angle between 30 to 35° the rotation speed of the reversely rotating drum at 120 to 130 r/min, and the matching hautage speed at 1.2 to 2m/min.
