Drilling apparatus with drill guide

An apparatus for use in connection using a drill having a drilling element for forming a borehole in a face of a mine passage, comprising:

• a drill guide for engaging the drilling element while permitting the drilling element to move toward the face for forming the borehole, the drill guide adapted for pivoting movement between a retracted position for releasing the drilling element from the drill guide and an active position for associating the drilling element with the drill guide;
• a retainer for holding the drill guide in at least the active position;
• and
• a controller for actuating the retainer on receiving at least one signal corresponding to the movement of the drill relative to the drill guide.

An apparatus for use in connection using a drill having a drilling element for forming a borehole in a face of a mine passage in connection with a mast, comprising:

• a drill guide for engaging the drilling element while permitting the drilling element to move toward the face for forming the borehole, the drill guide including at least one movable jaw;
• an elongated shaft extending along the mast and connected at one end to the at least one movable jaw;
• and
• an actuator adapted for rotating the elongated shaft for moving the at least one jaw of the drill guide.
