    When the hole is large enough, the miners dig down to the next layer of coal. Each layer is called a bench. Huge excavators extract the coal. The biggest of these machines is 240 meters long (longer than two soccer stadiums) and 96 meters high (equivalent to a 38story building). The buckets on the excavators can hold up to 300

  • Coal mining Prospecting and exploration Britannica

    The fundamental objective of coal prospecting is to discover coal resources through a search. In areas where coal mining has not been previously practiced, the search process should result in obtaining coal samples that give reasonable evidence of the existence of a coal seam. Once a seam has been discovered, considerable further work is necessary in

  • Fossil Energy Study Guide: 300 million years ago

    Th e process of converting coal into electricity has multiple steps and is similar to the process used to convert oil and natural gas into electricity: 1. A machine called a pulverizer grinds the coal into a fi ne powder. 2. Th e coal powder mixes with hot air, which helps the coal burn more effi ciently, and the mixture moves to the furnace. 3.
