Lake Puketirini
Lake Puketirini is a former opencast coal mine, immediately to the west of Huntly, New Zealand, Huntly and east of the larger, but much shallower Lake Waahi, in the Waikato, Waikato Region. It is circled by a walkway. History The area was initially known as Puketirini, which included Lake Rotoiti, which was shown on maps until 1949, though a 1944 map showed it as Westmere and drained. The west shaft of Huntly, New Zealand#Coal, Ralph Mine was at Puketirini and used for rescue after the 1914 explosion. The site was identified as a potential coal mine in 1929 and land was bought by the government between 1940 and 1980. Mining began on part of the site in 1954, or 1956. The initial mining used small excavators. From 1984 the mine was extended to the north. It was transferred to the Solid Energy, Coal Corporation in 1986 and Weavers opencast coal mine excavated the area until 1993, using a Bucket-wheel excavator, bucketwheel excavator and conveyor belt to dig out of overburden an ...

Hakarimata Range
Hakarimata Range is a range of hills on the western edge of Ngāruawāhia township, Retrieved 2016 in the Waikato region of New Zealand, overlooking the confluence of the Waikato and Waipā Rivers. The Hakarimata Range is separated from the Taupiri Range by the Taupiri Gorge, through which the Waikato River flows. After the invasion of the Waikato, parts of the Hakarimatas were confiscated in 1864. of native forest on the range are protected as a scenic reserve. A council supported community group, the Hakarimata Restoration Trust, created in 2001, is helping care for the range. Location Although now usually applied to the hills immediately west of Ngāruawāhia, maps such as Hochstetter's of 1859, the 1925 geology map and 1944 one inch map show 'Hakarimata Range' as extending south to what is now SH23. Similarly, old accounts describe the Whatawhata- Raglan road as passing over the Hakarimatas. Name Hakarimata's name derives from a 17th-century feast, when Ngāti Maniapot ...

Glen Afton Branch
The Glen Afton Branch was a branch railway line of 7.9 km (originally 14.1 km) in the Waikato in New Zealand, built to serve coal mines in the Awaroa district west of Huntly, New Zealand, Huntly at Rotowaro, Pukemiro and Glen Afton. Rotowaro is Māori for "coal lake". When handed over from New Zealand Ministry of Works, Public Works to New Zealand Railways Department, NZR in 1915 it was called the Awaroa Branch, but was also known as the Glen Afton Branch to about 1974, then as the Rotowaro Branch to 3 November 1988, then as the Rotowaro Industrial Line. By 2014 it was again named the Rotowaro Branch. History The first 5 km was authorised in 1910 and required a road-rail bridge over the Waikato River, with an extension which carried the railway over the main highway. The bridge, constructed from 1911 to October 1914, had 10 spans of Australian hardwood (8 of 30.5m and 2 of 12.2m) on steel and reinforced concrete piers.

Mesotrophic Lake
The Trophic State Index (TSI) is a classification system designed to rate water bodies based on the amount of biological productivity they sustain. Although the term "trophic index" is commonly applied to lakes, any surface water body may be indexed. The TSI of a water body is rated on a scale from zero to one hundred. Under the TSI scale, water bodies may be defined as: * oligotrophic (TSI 0–40, having the least amount of biological productivity, "good" water quality); * mesotrophic (TSI 40–60, having a moderate level of biological productivity, "fair" water quality); or * eutrophic to hypereutrophic (TSI 60–100, having the highest amount of biological productivity, "poor" water quality). The quantities of nitrogen, phosphorus, and other biologically useful nutrients are the primary determinants of a water body's TSI. Nutrients such as nitrogen and phosphorus tend to be limiting resources in standing water bodies, so increased concentrations tend to result in increased p ...

Unconsolidated
Soil consolidation refers to the mechanical process by which soil changes volume gradually in response to a change in pressure. This happens because soil is a two-phase material, comprising soil grains and pore fluid, usually groundwater. When soil saturated with water is subjected to an increase in pressure, the high volumetric stiffness of water compared to the soil matrix means that the water initially absorbs all the change in pressure without changing volume, creating excess pore water pressure. As water diffuses away from regions of high pressure due to seepage, the soil matrix gradually takes up the pressure change and shrinks in volume. The theoretical framework of consolidation is therefore closely related to the diffusion equation, the concept of effective stress, and hydraulic conductivity. In the narrow sense, "consolidation" refers strictly to this delayed volumetric response to pressure change due to gradual movement of water. Some publications also use "consolid ...

Overburden
In mining, overburden (also called waste or spoil) is the material that lies above an area that lends itself to economical exploitation, such as the rock, soil, and ecosystem that lies above a coal seam or ore body. Overburden is distinct from tailings, the material that remains after economically valuable components have been extracted from the generally finely milled ore. Overburden is removed during surface mining, but is typically not contaminated with toxic components. Overburden may also be used to restore an exhausted mining site during reclamation. Interburden is material that lies between two areas of economic interest, such as the material separating coal seams within strata.Peng, Syd S. (1986) ''Coal Mine Ground Control'' (2nd edition), Wiley, New York, page 303, Analogous uses Overburden is also used for all soil and ancillary material above the bedrock horizon in a given area. By analogy, overburden is also used to describe the soil and other material that lies ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Conveyor Belt
A conveyor belt is the carrying medium of a belt conveyor system (often shortened to belt conveyor). A belt conveyor system is one of many types of conveyor systems. A belt conveyor system consists of two or more pulleys (sometimes referred to as drums), with a closed loop of carrying medium—the conveyor belt—that rotates about them. One or both of the pulleys are powered, moving the belt and the material on the belt forward. The powered pulley is called the drive pulley while the unpowered pulley is called the idler pulley. There are two main industrial classes of belt conveyors; Those in general material handling such as those moving boxes along inside a factory and bulk material handling such as those used to transport large volumes of resources and agricultural materials, such as grain, salt, coal, ore, sand, overburden and more. Overview Conveyors are durable and reliable components used in automated distribution and warehousing, as well as manufacturing and produ ...
