所述履带行走装置1采用液压泵站3的高压油液驱动。
工作时，液压泵站3提供高压油液供给履带行走装置1，实现推进或移动该掘进机，液压泵站3还分别提供给悬臂盘驱动马达5、旋转密封装置12高压油液，高压油液通过旋转密封装置12的液压油进油口12-1-1，再经过密封轴12-2的进油流道一12-2-1、传动箱7的输出轴7-4的进油流道II7-4-1以及胶管传递至悬臂驱动马达10和驱动马达11-1，进而使悬臂驱动马达10控制悬臂9的摆动角度，悬臂盘驱动马达5通过行星减速机构6、传动箱7实现悬臂盘8回转运动，滚刀11-5在驱动马达11-1作用下主动旋转；悬臂驱动马达10锁紧悬臂9时，悬臂盘8、驱动马达11-1以及履带行走装置1同时工作使悬臂盘8和滚刀11-5同时旋转，即可实现掘进破岩；悬臂驱动马达10可以根据巷隧道端面大小调节悬臂9的姿态，主动旋转滚刀装置11工作时滚刀11-5自身旋转切削破岩，进而在悬臂盘8回转运动前提下实现巷隧道工作面岩体机械切削破碎；
高压磨料射流发生系统4得电后形成高压磨料液体通过旋转密封装置12高压磨料液体入口I12-1-3，依次经过磨料液体流道一12-2-3、传动箱7中输出轴7-4的磨料液体流道二7-4-3、高压磨料液体入口二11-2、磨料液体流道三11-8、磨料液体流道四11-9，最后通过喷嘴11-10形成高速磨料射流，在滚刀切削破岩路径上超前割缝岩石辅助主动旋转滚刀装置11破岩，降低主动旋转滚刀装置11切削破碎坚硬岩石难度，提高坚硬岩石巷道掘进效率。
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
