Tunnel Drilling Rig for Coal Mine During underground drilling construction, the drilling rig can independently adjust the height of the column as the height of the tunnel changes, and always maintain the effective support of the column top cover to the tunnel roof, thereby making the drilling rig work stably and eliminating the need for tunnel roofs. Potential safety hazards such as collapse or floor collapse ensure the safety of workers and equipment. The column has reasonable design, simple structure and convenient maintenance. It can be adjusted independently according to the height change of the mine tunnel and has the function of mechanical automatic compensation stroke. During the drilling operation of the drilling rig, when the top plate collapses, the bottom plate collapses, or the vibration of the drilling rig causes a gap between the top cover and the top plate, the column can use the compression power of the disc spring to extend the inner cylinder accordingly, quickly and effectively supporting the top plate. This column contains three sets of cylinders and can be used for drilling tunnels in mines with large height changes.
