NTIS: PB/81-217002 :154 pages
Drive systems for mining machines are usually sized to accommodate anticipated peak loads. Usually, the average power requirements are considerably less. Energy storage and power averaging are attractive concepts for mining machinery and could have far-reaching implications. The purpose of this program was to identify truly feasible concepts; identify advantages and/or disadvantages, limitations, and constraints; evaluate feasibility based on today's technology; identify anticipated safety problems; and provide the designer with a comprehensive literature base. Concepts evaluated include flywheels, high energy batteries, gas-charged accumulators, inductive storage, capacitive storage, springs and counterweights, thermal, closed cycles, internal combustion engines, and trolley and hybrid systems. A comprehensive index is provided, and an appendix is included containing abstracts of pertinent literature.
