Changes in coal seam hardness cause fluctuations in the feed resistance at the drill bit during the drilling process, leading to unstable feeding speed. This paper proposes a robust dynamic output feedback controller to suppress disturbances caused by the variations in coal seam hardness in the feed system. Firstly, an unknown parameter …

From there the material can be transported out of the tunnel without problems. After each jacking stroke, the drilling process is stopped for a short time, to secure the pipe string and the drilling unit. Then the next jacking pipe can be installed in the jacking frame. When the desired drilling length is reached, the drilling unit is retracted.
