  • FIGS. 1 and 2 the drill rig is illustrated in position for drilling holes vertically downwards. Due to the parallel arrangement of the trunnions 26 and the axis of the drill steel equipment 48 it is obvious that swinging of the outer frame 21 in clockwise direction as viewed in FIG. 2 by means of the power jack 31 moves the drill steel parallel to itself sideways on the axis or". the -trun-' nions 26 along an arc of a circle.

  • the operator is able to position the drill steel in strict parallelism with the axis of the column sections in any seiected position according to the drilling pattern between the full line position and the dotted line position 90 of FIG. 2 through an angle of 360 degrees and to keep the steel in any such position by means of the power jacks 69 and 31.
  • the steel plate 82 is firstly attached to the floor of the drift at a suitable location and firmly connected thereto by pouring concrete around the plate 82. Thereupon the rock engaging member 76 is bolted to the steel plate 82.
