Coal Mining and Processing | Energy Trends Insider
Processing the Coal After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal.

How it Works: Water for Coal | Union of Concerned Scientists
Electricity generation. Like all thermoelectric power systems, coal plants require cooling. Three major options are available: oncethrough, wetrecirculating, and dry cooling. About 53 percent of coal plants in the United States use oncethrough cooling, about 40 percent use wetrecirculating, and less than one percent use drycooling.

Coal: Anthracite, Bituminous, Coke, Pictures, Formation, Uses
Electricity production is the primary use of coal in the United States. Most of the coal mined in the United States is transported to a power plant, crushed to a very small particle size, and burned. Heat from the burning coal is used to produce steam, which turns a generator to produce electricity.
