ABSTRACT Mining apparatus for sublevel caving is disclosed in which a single conveyor fed by a power loader is protected by a roof plate which extends substantially horizontally in contact with the roof of the bed. A back plate is joined to the roof plate and also extends generally horizontally but with a space between it and the roof. The back plate and roof plate are supported by props. A door is provided in the back plate and this can be pivoted so that its edge adjacent the roof plate moves downwardly towards the conveyor thereby acting as a chute. Pivotting is effected by hydraulic props attached to a base. When the door is in the up position it engages the underside of an edge of the roof plate thereby assisting in supporting the roof plate.
