Systems for and techniques for constructing suitable emplacement holes are being considered for an underground nuclear waste repository. This study is an investigation of methods to bore and line horizontal boreholes of varying lengths. The development prototype boring machine already designed has been selected to bore the long holes (350 ft.), while the method selected to bore short holes, 42, 58, and 75 ft. involves two separate systems: one to bore the hole, the other to line the hole. The systems described in this report are not off-the-shelf, but represent a reasonable extension of current technology.
