ABSTRACT In 1992, the Colorado School of Mines (CSM) laboratory, under DOE sponsorship, began testing very small, 5 inch diameter cutters built by Excavation Engineering Associates, Inc, (EEA), These cutters utilized an entirely non-traditional mounting method, shaft, and bearing structure, As a result, the 5 inch EEA? Mini-disc cutter could accept as much as 30,000 lbs load, Laboratory test results were both extensive and outstanding, Many applications surfaced for these small, robust cutters: microtunneling, back reaming, oil well and blast hole drilling, seam mining and special purpose excavation equipment. A number of field trials on various applications have been on going This paper and presentation will provide insight to the development of this interesting new tool, present data from laboratory and field trials, and show some of the applications under development.
