Abstract
A roof mesh installation apparatus for a mining machine includes a mesh roll carried at a dispenser at a forward position of the machine capable of unrolling mesh to be laid and bolted at a tunnel roof. A tensioning device positioned at the dispenser is capable of actuation so as to apply a pre-tension to a forward and unbolted section of mesh with the tension being applied against an already laid and rearward bolted mesh section. Accordingly, an automated roof mesh installation apparatus and method is provided.
Claims16
A roof mesh installation apparatus for a mining machine comprising:
- a dispenser arranged to mount a roll of mesh ready for unrolling and securement against a roof by bolting;
- a tensioning device having a mesh engaging portion, the tensioning device being movable between a first position wherein the mesh engaging portion penetrates into or through an open structure of the mesh so as to lock the tensioning device to the mesh and a second position wherein a forward and unbolted section of the mesh is tensioned against a rearward and already bolted section of the mesh by forward and/or upward movement of the tensioning device prior to bolting, the tensioning device being selected from a wheel, drum or roll;
- and
- at least one mechanical actuator mounted at the machine configured to provide the forward and/or upward movement of the tensioning device.
