Coal mining Underground mining Britannica

Coal haulage, the transport of mined coal from working faces to the surface, is a major factor in underground-mine efficiency. It can be considered in three stages: face or section haulage, which transfers the coal from the active working faces; intermediate or panel haulage, which transfers the coal onto the primary

How coal is used Primary

2018-1-5  1. Coal is mined either by surface or by underground mining. Before it leaves the mine, it is often cleaned, crushed, and sorted. 2. 2. About 2/3 of our coal is transported by rail, much of it in special cars. One coal train can carry as much as 10,000 tons per trip. 3. 3. 46% of U.S. electrical generators are powered by coal.
