Abstract:
A drilling or bolting unit for selective use with either a vehicle or a panline of a face conveyor associated with a longwall miner or mining machine is disclosed. In one embodiment, the unit comprises a base adapted for engaging the panline and a plurality of receivers. Each receiver may be adapted for receiving one of the pair of forks of the vehicle, such that the unit may be used as either a panline drilling or bolting unit or as a utility drilling or bolting unit with the vehicle apart from the panline. Related methods are also described.
