The U.S. Energy Information Administration’s (EIA) latest Annual Coal Report (ACR) shows that U.S. coal mining productive capacity, or the maximum amount of coal that mines can produce in a year, totaled 1,009 million short tons (MMst) in 2019. This amount represents a 28% decrease from the peak productive coal mine capacity of 1,407 MMst reported in 2009. U.S. coal production declined by 35% during the same period because many coal mines closed and the remaining mines produced less coal.
