NTIS: PB/80-158793 :49 pages
Recognizing the hazards associated with roof bolting in underground coal mines, and the need for improved technology to reduce these hazards, the Bureau of Mines entered into an agreement with contractors to build a production model, second-generation automated bolter that would utilize the basic technology of remotely controlled single-boom bolters. This report describes a new dual- boom, remotely controlled roof bolter that was designed, fabricated, and tested in an underground coal mine.
