ABSTRACT:
A travelling mining appliance, particularly a travelling drilling and/or bolting appliance, having a protective roof. The appliance comprises a driving station used for controlling the movement of the appliance on the ground and a separate operating station, located on the side of the appliance, for controlling the drilling and/or bolting device. According to the invention, the roof is mounted to pivot on the appliance about a vertical axis. It is thus able to move in an angular manner between a first position in which it is located above and protects the driving station, without projecting beyond the width of the appliance and a second position in which projects beyond the side of the appliance and is located above the operating station thus protecting the operator who is standing opposite this station.
