UNDERGROUND BLAST HOLE DRILLING MACHINE Abstract of Disclosure A mobile drilling machine in which a mobile support vehicle of the hydrostatic type provides the power supply fox the majority of the hydraulic components on the drill- ing head frame, the latter being adjustable through two axis of pivot with its mounting on the head frame for any angle of drilling. The head frame mounts the drill head which advances and withdraws drill rods or a drill string in a drilling operation. It supplies the rotational torque to the drilling string and provides pneumatic air passage therethrough to a drill tool at the end of the drill string at which the major portion of the drill- ing force is applied. This isolates these drill forces from the drill head and head frame to minimize wear on the drilling apparatus.
