It is concluded: during the period of cutting coal and rock, drum resistance torque, radius acting force and responses of structure straight-line vibrating and drum twist vibrating vary with the variation of shearing media.

• 得出：由于采煤机滚筒在切割煤岩的过程中，随着截割介质(煤或岩)的变化，滚筒的阻力矩、径向作用力以及由截割力激励所产生的结构直线振动响应和滚筒扭转振动响应都要随之发生变化。
