旧奔別炭鉱立坑櫓

旧奔別炭鉱立坑櫓は、北海道三笠市に残る炭鉱遺構で、かつて「東洋一の立坑」と呼ばれた巨大な立坑櫓です。 明治33（1900）年から昭和46（1971）年まで操業した旧奔別炭鉱では、累計約2,650万トンもの石炭が採掘され、日本の近代化と北海道開発を支えました。 現在残る立坑櫓は高さ約51m、内径約6.4mを誇り、人員や資材、石炭を効率的に運搬するための国内初のシステムを採用した、当時最先端の施設でした。 巨大な鉄骨構造と炭鉱施設群は、かつて炭鉱で栄えた三笠の歴史を今に伝えており、三笠市を代表する炭鉱遺産のひとつとなっています。 The Former Ponbetsu Coal Mine Headframe is a historic coal mining structure located in Mikasa City, Hokkaido, and was once known as the “largest mine shaft tower in the East.” The Ponbetsu Coal Mine operated from 1900 to 1971, producing approximately 26.5 million tons of coal that supported Japan’s modernization and the development of Hokkaido. The remaining headframe stands approximately 51 meters tall with an inner diameter of about 6.4 meters, and was considered a state-of-the-art facility at the time, adopting Japan’s first system for efficiently transporting workers, materials, and coal through a single shaft. Today, the massive steel structure and mining facilities preserve the history of Mikasa’s once-thriving coal mining industry and remain one of the city’s representative industrial heritage sites.
