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] |
Mikasa, Hokkaidō
is a city located in Sorachi Subprefecture, Hokkaido, Japan. As of September 2016, the city has an estimated population of 9,056, and the density of 30 persons per km2. Geography The total area is 302.64 km2. It is bordered on three sides by mountains, and on its east side is the man-made Lake Katsurazawa. History Mikasa is one of the birthplaces of the mining and railroad industries in Hokkaido, and the Hokkai Bon song was invented there. Though in the past it flourished due to its natural abundance of coal, the mines have largely closed down and this has caused the population of the city to fall rapidly. Quite a few fossil specimens have also been collected there, particularly ammonites and the prehistoric marine reptile '' Yezosaurus mikasaensis'', both of which can be viewed at the city's natural history museum. *1906 - Mikasayama village was founded. *1942 - Mikasayama village became Mikasa town. *1957 - Mikasa town became Mikasa city.

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] |
Former Coal Mines
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the ...

Buildings And Structures In Hokkaido
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, monument, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the :Human habitats, human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hokkaido Colliery And Railway Company
was a company engaged in coal mining, railway operation and shipping in Hokkaidō, Japan. The company was established in 1889 when the state-owned and Horonai Railway were sold to the company.

Biography Benjamin Smith Lyman was born in Northampton, Massachusetts. He graduated from Harvard University in 1855. After working briefly as a school teacher, he worked as an assistant to his wife's uncle on a topographical and geological survey of Broad Top Mountain in Pennsylvania, which spurred his interest in geology and mining engineering.
