ABSTRACT:
A method and apparatus for drilling a vertical hole from an underground chamber to the surface includes the emplacement of a preassembled, vertical drill string including a drill bit mounted in a cylinder installed below the underground chamber. When vertical drilling is required, piston lifts the drill string and extends it from the cylinder into the overlying rock. Circulating fluid drives the drill bit and removes the rock debris from the resulting, vertically progressing hole. Drilling continues until the surface is penetrated, and the drill string is retracted into the cylinder, enabling access to the surface through the resulting hole.
