Chosen Coal Industry Company

The Chosen Coal Industry Company (Japanese: 朝鮮石炭工業株式會社 Chōsen Sekitan Kōgyō Kabushiki Kaisha; Korean: 조선석탄공업주식회사 Joseon Seoktaneop Jusikhoesa) was a kabushiki kaisha in colonial Korea that operated collieries in Aoji, Sinaoji and Obong in Gyeongheung County, North Hamgyeong Province. In addition to the mines, after the Chosen Synthetic Oil Company opened a large factory in Aoji-ri (now Haksong-ri) in 1937[1] to produce synthetic oil from the bituminous coal mined in the area,[2] the Chosen Coal Industry Company built a railway line, called the Ao Line, to connect its mines to the chemical factory and to the South Manchuria Railway's North Chosen East Line, opening the line in two parts in 1938 and 1942.[3][4]
