Products Produced From Coal Strip Mining

Sep 26, 2019 Mining was usually done formerly by hand with primitive tools, although gasoline locomotives were sometimes used. Most mines were small, yielding between 10,000 and 50,000 tons per year, and the bulk of coal produced was used within the state. Though railroads were early purchasers, they found the quality poor and used it only sparingly
