Abstract

A raise drill apparatus (10) includes a base (12) upon which is mounted a support column (14) for supporting torque and thrust producing equipment (16, 18). A support frame (24) is connected to the column (14) by pins (28) and, in use, is secured to the ground by rock bolts to support the column (14) cantilevered over a hole being raise drilled. In order to allow maximum thrust to be applied during most of the raise drilling operation, removable supplementary front supports (40) are provided on the base (12) on the side of the support column (14) remote from the frame (24). The supplementary supports (40) assist in supporting the machine until the raise bit is within a short distance of the base (12) and are then removed to allow raise drilling to be completed at a reduced thrust. <IMAGE>
