摘要： An apparatus for drifting openings in hard rock incorporating a carrier capable for travelling along the floor of the opening. A means of breaking of the percussive type is mounted on the carrier by means of a turnable jib with provision for turning about said jib in a vertical plane. There is also incorporated a means of loading with a mucking conveyor. Employed as the means of breaking with a percussion tool directly acting upon the rock so as to break same when the means of breaking is set into a given position. Also provided are means of shock-absorbing which serve to link up movably said means of breaking with said jib in order to absorb the undesirable deflections of the means of breaking when the percussion tool recoils from the rock at right angles to the longitudinal axis thereof and to return the means of breaking into the given position. The jib also turns about the carrier in a horizontal plane so that the means of breaking can be readily set up in position for breaking any area of the rock face of the drifted opening which is being tunnelled or mined.
