A module is for use in drilling a borehole in face of a mine passage using a drilling element and installing a bolt in the borehole once formed. The module may include a bolt holder for holding a plurality of bolts and a drilling element holder for holding a plurality of different drilling elements. A manipulator moves along an arcuate path between the bolt and drilling element holders to deliver the respective components to a drill head positioned along the arcuate path. The drill head may also slide relative to the mast in two different directions, and includes a drill guide for determining the location of the face to be worked. Related aspects of control of the module and methods are disclosed.
