(Japanese: 朝鮮無煙炭株式会社 Chōsen Muentan Kabushiki Kaisha; 조선무연탄주식회사; Joseon Muyeontan Jusikhoesa) was a kabushiki kaisha in colonial Korea that operated collieries around Korea.It was founded in 1927 by the Mitsubishi zaibatsu of Japan by integrating the anthracite mining operations around Heijō, eventually becoming the largest coal-producing company in Korea - 74.9% of the coal distributed in Korea was produced by the Chōsen Anthracite Company.[1] On 17 December 1943 the Chōsen Anthracite Company opened a railway line from Bunsen on the Chōsen Government Railway's Kankyō Line to a port it had constructed at Kogan-dō, Bunsen city, Gangwon Province.Named the Bunsen Port Line, it ran 7.4 km (4.6 mi) from Bunsen Station to Genzan North Port Station.The Muncheon Port Line, along with all other railway lines in the country, was nationalised on 10 August 1946, becoming part of the Korean State Railway.
