Coal County, Oklahoma. Coal County is a county located in the U.S. state of Oklahoma. As of the 2010 census, the population was 5,925. Its county seat is Coalgate.
The coal comes from the Cretaceous Laramie Formation. Mining began in the late 1850s and stopped in 1979. Large lignite deposits are present in the Paleocene Denver Formation in the central part of the basin, in a north-south belt east of Denver and Colorado Springs, in Adams, Arapahoe, Elbert, and El Paso counties. Some mining was done from about 1886 to 1940, but was reportedly minor.
