Versatile Boxhole Borer


Terratec has launched a new boring rig to expand its raise boring product line. The company’s UB1000 universal boxhole boring machine is designed to produce boxhole sections up to 1.06-m diameter x 100-m long and can also ream conventional raises nominally 1.8-m diameter x 200-m deep. Major components include the derrick assembly, featuring a gearbox complete with floating drive box (chuck) suitable for a 10-in. diameter x 48-in.-long drill string. The gearbox is designed so it can be positioned with the drive box pointing up for boxholes, or down for conventional raising. The machine is equipped with a gearbox turning cradle able to quickly and easily index from boxhole mode to raise-bore mode in less than one shift. Integrated torque column/thrust cylinders provide balanced thrust and clear access from all sides. The unit is able to operate at up to 45º dip, either side of the center line, in a “cross-drift” orientation, with no requirement to turn the rig first, or any modifications to change from left hand to right hand dip. Drill rod feed cassettes are supplied and each holds 10 rods. The cassettes are mechanized to feed one rod at a time to the rod handler, and accept one rod at a time from the pipe loader when removing rods from the machine. The feed cassette is powered from the hydraulic power unit. Machine mobility comes from a radio-remote controlled transport/erector crawler powered by a 104-kw diesel.
