A mining machine is disclosed which has a vehicle body with a first end thereof having a boom pivoted for up and down rotational movement about an axis extending transversely of the vehicle. A cutter head is carried by the boom and a conveyor is mounted on the vehicular body to carry away material cut by the cutter head. A dust collection system is mounted on the boom and vehicle body to convey dust away from the cutting head area. The dust control system has duct work associated therewith which includes a generally rectangularly intake duct section associated with the boom and a generally rectangularly fixed duct section mounted on the vehicle. A transition section connects the intake and the fixed duct sections. The transition section consists of a two piece arrangement wherein each piece is hinged to the intake duct section and is capable of slidingly engaging the fixed duct section at the end thereof adjacent the boom to sealing couple the intake duct section to the fixed duct section as the boom swings upwardly and downwardly.
