Abstract

The invention provides a rock drill adaptor which makes use of the supportive function of a rock drill associated with an air leg or a similar mounting device (hereinafter also referred to as "a vertically extensible support") as a means to inflate a pressure vessel, such as a rock bolt, and retain a mesh support against a rock wall simultaneously.
