Its headquarters are located in Gangwon State, in Wonju.

Korea Coal operates three domestic anthracite coal mines, producing approximately 1.2 million metric tons annually.

As domestic demand for bituminous coal has grown, exceeding 70 million tons in 2005, the company has reduced its Korean operations and begun to invest in overseas mines.

The company was initially formed in 1950, under the First Republic of South Korea.

It was the successor to a Japanese government corporation set up under Japanese rule, when large-scale coal-mining in Korea began.
