The top 25 active mines in the region produced 6.28 million tons of coal during the last three months of 2020, an 8% increase from 5.8 million tons in the preceding quarter and nearly equal to the 6.27 million tons of coal mined in the prior-year period. The basin yielded 24 million tons of coal over all of 2020, a 14.3% drop from 28.1 million tons of coal mined during 2019.
