Coal Mining: How Is Coal Mined?
Coal Mining Process. The US burned roughly 700 million tons of coal in 2016—enough to fill a standard railroad car every 4 seconds. 90% of that coal consumption went into the generation of electricity, while the rest (just 10%) was burned for other industrial/commercial requirements. All of this coal comes from mines that are either …
