Mining - A Problem in Earthmoving

The mining industry of the United States moves about 7 billion tons of earth and rock per year. Much conventional earthmoving equipment is used in mining, particularly surface mining, but the special problems of the industry suggest that machines designed for mining would be better than machines designed for the construction industry in many applications. Underground mining now uses little automotive equipment.

Systems of mining are reviewed to suggest to designers possible applications for new types of automotive equipment.
