In recent years,coal mining has tended towards a deeper trend.The bottom bulge of the roadway surface caused by the pressure from the mine floor and the difficulty in meeting the requirements for roadway surface paving and driving during coal seam excavation have seriously affected the normal production operations of coal mines,and even more so,there are significant safety hazards in production.The tracked tunnel milling and planing machine used in coal mines can meet the safety production requirements of the mine after milling and planing the bottom bulge of the tunnel floor and the uneven height of the coal seam road surface.
