Abstract
An apparatus abates noise from the operation of a drill head including a drilling element for engaging a face of a mine passage during a drilling cycle in which the drill head moves from a first position farther from the face to a second position closer to the face. The apparatus includes a collapsible barrier capable of moving between an extended condition to cover a portion of the drilling element during the formation of the borehole and a retracted condition in which the portion of the drilling element covered in the extended condition is exposed. A holder is adapted for releasably coupling with the barrier in the extended condition. Related methods are also disclosed.
