By the beginning of World War Two, the Ernest coal plant began to resemble the plant best remembered by most Indiana Countians. As the war effort increased, Ernest kept pace with a growing need for coal and, in 1945, the mining and preparation plant worked together to produce over a million tons of coal.
In 1952, the McNally plant was built an the hillside behind the original site. Using a wet cleaning method to separate the coal from impurities, the McNally plant had a capacity of fifty tons per hour for coking coal. R amp P later expanded this plant to clean four hundred tons per hour, and it contained all of the cleaning equipment used at Ernest. By the early 1960s, RampP officials decided that coal could no longer be mined profitably at Ernest. In 1965, the plant
Coal mining increases the risk of loosening top soils into streams and waterways and the sediments pollute our water and can smother plant life downstream and even kill fish. Coal has traces of sulfur and nitrogen. When burned, these are released into the atmosphere. While these chemicals are floating in the air, they can mix with water vapor ...
Coal mining - Coal mining - Coal preparation As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous intrusions.
