Hokutan Horonai Coal Mine
The is the oldest mine of the Ishikari coalfield of the Sorachi ( Mikasa) mining region on the Japanese island of Hokkaido. Since its privatisation in 1889, the mine came under the management of the Hokutan company until its closure in 1989. The Startup In 1868, carpenter Kimura Kichitarō (木村 吉太郎) discovered coal in Horonai, Mikasa (三 笠). However, it took another 6 years before Chōjūrō Hayakawa a citizen of Sapporo, delivered the first coal to the colonization commission (開拓使, Kaitakushi). The local government took action, and the mining engineers Benjamin Smith Lyman and Takeaki Enomoto welded an investigation. Their findings were satisfactory, and the Meiji government decided to build in Horonai the first coal mine of the Ishikari coal basin.Kasuga YutakaTransfer and Development of Coal-Mine Technology in Hokkaido pp. 11-20. The construction of the mine was led by the American engineer L.C.E. Goujot and his disciple Edward Parry. The first ad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coal Mines In Japan
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
