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, boast ... [...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 ...

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 adv ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Kitakami River
The is the fourth largest river in Japan and the largest in the Tōhoku region. It is long and drains an area of . page 793 It flows through mostly rural areas of Iwate and Miyagi Prefectures. The source of the river is the Mount Nanashiruge in northern Iwate, from which it flows to the south between the Kitakami Mountains and the Ōu Mountains. The river is unusual in that it has two mouths, one flowing south into Ishinomaki Bay and the other flowing east into the Pacific Ocean, both in Ishinomaki City. The Kitakami river was an important transportation route during the Edo period and before the building of railways in the early Meiji period. Numerous dams have been constructed on the river and its tributaries from the Taishō and Shōwa periods for hydroelectric power generation, flood control and irrigation. However, another unusual feature is that there are no dams from its mouth to the Shijūshida Dam north of Morioka. This allows for a spectacular salmon run every ...

Arsenic
Arsenic is a chemical element with the symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic is a metalloid. It has various allotropes, but only the gray form, which has a metallic appearance, is important to industry. The primary use of arsenic is in alloys of lead (for example, in car batteries and ammunition). Arsenic is a common n-type dopant in semiconductor electronic devices. It is also a component of the III-V compound semiconductor gallium arsenide. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining with the increasing recognition of the toxicity of arsenic and its compounds. A few species of bacteria are able to use arsenic compounds as respiratory metabolites. Trace quantities of arsenic are an essential dietary element in r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Heating
A central heating system provides warmth to a number of spaces within a building from one main source of heat. It is a component of heating, ventilation, and air conditioning (short: HVAC) systems, which can both cool and warm interior spaces. A central heating system has a furnace that converts fuel or electricity to heat. The heat is circulated through the building either by fans forcing heated air through ducts, circulation of low-pressure steam to radiators in each heated room, or pumps that circulate hot water through room radiators. Primary energy sources may be fuels like coal or wood, oil, kerosene, natural gas, or electricity. Compared with systems such as fireplaces and wood stoves, a central heating plant offers improved uniformity of temperature control over a building, usually including automatic control of the furnace. Large homes or buildings may be divided into individually controllable zones with their own temperature controls. Automatic fuel (and sometimes ash ...

Flush Toilet
A flush toilet (also known as a flushing toilet, water closet (WC) – see also toilet names) is a toilet that disposes of human waste (principally urine and feces) by using the force of water to ''flush'' it through a drainpipe to another location for treatment, either nearby or at a communal facility, thus maintaining a separation between humans and their waste. Flush toilets can be designed for sitting (in which case they are also called "Western" toilets) or for squatting, in the case of squat toilets. Most modern sewage treatment systems are also designed to process specially designed ''toilet paper''. The opposite of a flush toilet is a dry toilet, which uses no water for flushing. Flush toilets are a type of plumbing fixture and usually incorporate an "S", "U", "J", or "P" shaped bend called a trap that causes water to collect in the toilet bowl to hold the waste and act as a seal against noxious sewer gases. Most flush toilets are connected to a sewerage system that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
