Annual Survey of Coal Production and Preparation. Between 1980 and 2000, U.S. coal mining labor productivity increased at an average rate of 6.7 per year, from 1.93 short tons per miner-hour to 7.02 short tons per miner-hour. The major factors underlying these gains were inter-fuel price competition, structural change in the

One way to reduce coal preparation cost, which is expressed on the basis of cost per ton of clean coal, is to increase the amount of clean coal recovered from a given amount of raw coal without adding to the total cost incurred in the preparation of that coal. The main objective of this project was to develop a plant optimization model to ...
