通过驾驶员的操作，使动力装置9工作，使步履行走装置10带动整机行走至施工地点，通过加压油缸6加压，动力头7转动，带动钻杆4和钻头14旋转取土，取土完成后通过卷扬机8和钢丝绳5的带动下钻杆4和钻头14上升，把取土器19滑动至钻头14下方，利用卸土器13把钻头14内的钻取物卸至取土器19中，卸土完成后把取土器19滑动原位置，通过装载机等车辆把取土器19中的钻取物堆放在指定地点。通过反复的钻取动作完成整个作业施工过程。
当遇到大孔径及大扭矩施工时，利用设置在固定支脚16中的防滑销21来固定住该旋挖钻机，放置该钻机发生位移现象。
通过驾驶员来控制步履行走装置10。通过控制支脚油缸23的伸缩，来调节移动支脚15和固定支脚16与地面受力情况的交替运行。通过控制纵向行走油缸24的伸缩达到旋挖钻机的前后行走和左右转向。在旋挖钻机作业时，可使移动支脚15与固定支脚16同时与地面接触受力，以达到旋挖钻机的最佳平稳性。
控制支脚油缸23，使支脚油缸23缸杆伸出，使移动支脚15向下与地面接触，提升固定支脚16离开地面，支脚油缸23停止运动。
控制纵向行走油缸24的缸杆向前伸缩，带动移动支脚15向前滑动，这一过程在纵向行走油缸24达到最大行程为止。
控制支脚油缸23，使支脚油缸23缸杆缩回，使移动支脚15向上提升离开地面，固定支脚16与地面接触，支脚油缸23停止运动。
控制纵向行走油缸24的缸体向前伸缩，带动固定支脚16向前滑动，这一过程在纵向行走油缸24达到最大行程为止。
