The 7-Steps of Generating Electricity from Coal – Coal Mining
Step 1: Mining. The first step in the process of generating electricity from coal is to mine it. Coal is typically found in underground mines or in open-pit mines. The coal is extracted using large machinery, such as draglines and shovels. Once the coal is mined, it is transported to a power plant via truck, train, or conveyor belt.
