Abstract

Te consumption of energy in the U.S.A. is increasing every year. But the contribution of coal to the total annual energy requirement is decreasing owing to serious competition from oil and natural gas. The present annual rate of coal production is 410 million tons, which is expected to go up to 435 million tons by the end of 1960. In spite of mounting labour and supply costs, the coal industry has successfully maintained the price of coal at $5.0 per ton for the last ten years. This has been attained by the adoption of mechanization in mining, handling and transportation. Increased mechanization in mining has led to the production of coal with higher proportion of impurities. As a consequence, the producers had to resort to complicated, highly automatic large coal preparation plants to meet consumers’ requirement.
