Drilling apparatus with drill guide

摘要

An apparatus for use in connection using a drill having a drilling element for forming a borehole in a face of a mine passage includes 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 includes a keeper for keeping the drilling element in a desired position, which keeper is biased for pivoting movement upon the application of a manual force between an active position for capturing the drilling element and a retracted position for releasing the drilling element. A low profile drill guide is also disclosed, as is a guard for a drill guide, and also related methods.
