In setting the mine up Thiess incorporated a number of innovations that included the tonne double chamber hopper in the ROM Run of Mine dump area. It also uses Abon sizing technology as opposed to the usual rotary breaker technology. The reasoning behind this decision being lower the production of fine coal when crushing this means the operation doesn't require any separate screening. High Quality Coal Taken to Newcastle for Shipping Overseas The infrastructure also has a 2, tonne surge bin feeding the dual module washing plant.
This in itself operates by utilising dense medium spirals and cyclones that produce the semi-soft coking coal, mid ash thermal coal and low ash thermal coal for export purposes. Rejects are handled via an automated bin straight into haulage to be taken to waste dumps. The marketable de-watered coal product goes to a , tonne stockpile from where it is loaded into rail cars at a speed of 4, tonnes an hour. This train takes the coal seven kilometres to the main freight line to the west of Camberwell where it is then taken to the port at Newcastle for shipping overseas.
The Mount Owen complex of Glendell and Ravensworth East are all owned by Xstrata Mount Owen, formerly the Hunter Valley Coal Corporation, for its parent company Swiss owned Xstrata. Thiess contracting operate the mine on a daily basis under an agreement with the owner. The amalgamation of the adjoining properties has increased the resource, such that in mid marketable proven and probable reserves stood at Mt, with the overall resource estimated at Mt. OPEN PIT MINING Thiess Contractors operates Mount Owen as a shovel-and-truck open pit, relying on hydraulic excavators for both overburden stripping and coal production.
The dipping structure of the deposit means that the pit is laid out with benches spaced at 5m vertical intervals. Thiess has recently augmented its overburden fleet of Caterpillar B and C, t-capacity trucks, with six Liebherr T electric-drive haulers, while using Cat Bs for coal haulage. The Rs can accurately four-pass load the haulers through the use of real-time data transmitted from sensors mounted on the truck bodies to an Advanced Systems Integration monitoring unit on the shovel.
The actual cost was well within this limit. The plant was designed on a modular basis to produce 3. The Mount Owen Mine commenced open-cut operations in Umwelt, , p. Additionally, this approval allowed for a new satellite pit the Eastern Rail Pit and increased processing capacity. Mount Owen Mine is about 25 km north-west of Singleton, 26 km south-east of Muswellbrook and 10 km north of Camberwell Umwelt, , p.
Mount Owen Continued Operations Project is proposed to extend the life of the Mount Owen Mine until providing an additional 92 Mt coal although total annual ROM production is not planned to change Glencore, k. See also Section 1. The mine is operated by means of large excavators and haul trucks supported by ancillary equipment including water carts, dozers, graders, fuel and service carts, loaders and drills.
The coal that is uncovered is hauled to the CHPP for processing. Clean coal is conveyed to the product stockpile before being transported by rail for approximately km to the Port of Newcastle for export. Water is used at Mount Owen Mine for coal washing, dust suppression and amenities. The major water use is coal washing, which accounts for approximately Average daily water usage for dust suppression is 1. Ravensworth East Mine Ravensworth East Mine, formally known as Swamp Creek Mine previously mined by Hebden Mining Company operates under the management of Glendell Glencore, l Ravensworth East page.
The Ravensworth East Open Cut Mine was acquired in June by Peabody Resources Limited Peabody after a period of care and maintenance under the previous owner, Electricity Commission of NSW Xstrata Coal, , p. Ravensworth East Mine is owned by Glencore Coal Australia Pty Limited Glencore since , and operates under the management of Glendell Tenements Pty Ltd. Mining activities are conducted by Glencore Glencore, b, p.
Mining operations recommenced in August , and mining is expected to continue for up to 21 years under the current operation schedule Glencore, b, p.
