Abstract: An apparatus for driving an upwardly directed shaft in rock, which includes a platform that can be regulated in height. The platform carries a drilling unit having engageable elements enabling fixation of the drilling unit relative the wall of the shaft. The drilling unit and platform can be separated a given distance such as to form an air gap for preventing the transfer of vibrations from the drilling unit to the platform when a drilling machine pertaining to the drilling unit is in operation. The apparatus has bracket elements and a transverse member for limiting the separation distance between the drilling unit and platform. The platform carries a work station for a drilling machine operator.
Abstract: An assembly for raise mining or the like includes a drive support carrying a drive means (10) for driving the drive support along a guide (4). The guide is attached to the drift wall (2) and is successively lengthened concurrently with the drift driving. The drive support carries at least one drill boom rig (62) for mechanized drilling, and an operator's and service platform (40). The operator's and service platform (40) is carried shiftable with respect to the drive support in the direction of the guide (4) between a lower position, in which it does not obstruct the working movements of the drill boom rig (62), and upper positions, in which the drill boom assembly (62) in a collapsed non-operative position extends through an opening in the operator's and service platform (40).

Abstract: A cutter wheel is mounted at the lower end of the machine for rotation about a horizontal tubular support. Cuttings are picked up by buckets on the cutter wheel and are directed into the tubular support to be received by an endless bucket conveyor which carries them upwardly to a discharge station. As the machine is advanced the cutter wheel is rotated to make a first cut in the shape of the leading portion of the cutter wheel. The cutter wheel is then retracted out from the cut and is rotated about the axis of the hole. This repositions the cutter wheel so that when it is advanced again it will make a second cut which crosses the first. This procedure is repeated until the desired cross-sectional configuration (e.g. circular) of the hole is obtained.
