Rumoi coalfield
|
A coalfield located in the northwest of Hokkaido, west of the Teshio Mountains. The Showa, Uryu, Toyohira, Yoshizumi, and Haboro coal mines were developed and prospered, but all but Yoshizumi closed between 1969 and 1971. Yoshizumi Mine was a small-to-medium-sized mine, but it was mainly made up of low-cost outcrop coal, and was sent by truck to the Sunagawa thermal power plant, where it was used as fuel for power generation for a while, but is now closed.

北海道の北西部，天塩山地の西側にあった炭田。昭和，雨竜，豊平，吉住，羽幌の各炭鉱が開発されて発展したが，吉住を残して 1969～71年に閉山。吉住鉱は中小鉱であるが，低コストの露頭採炭が多く，砂川の火力発電所にトラックなどで送炭，発電用燃料としてその後しばらく利用されていたが現在は閉山。
