Matsuo Mine
, was an iron and sulphur mine located in the village of Matsuo, Iwate Prefecture in the Tohoku region of northern Japan. The area is now part of the city of Hachimantai. The mine opened in 1914 and closed in 1979 leaving a ghost town behind. History The Hachimantai Plateau where the mine is located in Ōu Mountains of central Honshu is a volcanic area and the presence of sulphur deposits was well known from an early age; however, due to the remoteness of the area and difficulty of transport, these deposits were not exploited. Iron pyrites were discovered by local villagers in 1882 in Matsuo village. In 1911, a Yokohama-based trading company, Matsuda-ya, began modern mine development at an altitude of at the base of the peak of Higashi-Hachimantai. In 1934, the Japanese Government Railway Hanawa Line was extended to near the mine, and Ōbuke Station was established. At one point, the Matsuo mine accounted for 30% of Japan’s sulphur production and 15% of its pyrite, boastin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Matsuo, Iwate
was a village located in Iwate District, Iwate Prefecture, Japan. The village of Matsuo was created on April 1, 1889 within Kita-Iwate District with the establishment of the municipality system. Kita-Iwate and Minami-Iwate Districts merged to form Iwate District on March 29, 1898. On September 1, 2005, Matsuo, along with the towns of Ashiro and Nishine (all from Iwate District), was merged to create the city of Hachimantai and no longer exists as an independent municipality. Matsuo was formerly known as the home of Japan's largest sulfur mine—the Matsuo Kōzan —and, later, as the home of the Matsukawa geothermal power plant. The iron and copper Matsuo mine was also located there before abandonment in 1971. As of September 2005, the village had an estimated population of 6,786 and a population density of 28.89 persons per km². The total area was 234.85 km².

Open Pit
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. It is applied to ore or rocks found at the surface because the overburden is relatively thin or the material of interest is structurally unsuitable for tunnelling (as would be the case for cinder, sand, and gravel). In contrast, minerals that have been found underground but are difficult to retrieve due to hard rock, can be reached using a form of underground mining. To create an open-pit mine, the miners must determine the information of the ore that is underground. This is done through drilling of probe holes in the ground, then plotting eac ...

Former Mines In Japan
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 ad ...
