Abstract

This invention relates to a rock drill guide comprising: a sleeve (20), having an internal chamber (30), adapted to receive a rock drill (40) therein, the sleeve (20) terminating in an operative end (50) and a drilling end (60), the sleeve (20) further being connectable to a pressure source for pressurising the sleeve (20); a pair of seals cooperating to seal the sleeve substantially hermetically, so as to maintain the pressurisation of the sleeve; and a pressure control mechanism, for selectively pressurising the chamber. The invention also relates to a kit for a rock drill guide.
