Nant Helen coal mine, based in the village of Coelbren, is one of Celtic Energy''s largest operational sites and has about three million tonnes of coal reserves. It was first granted permission in 1998 and by 2016, supported just over 100 employees, but a fall in demand saw the pit mothballed later in the same year.
BMA operates seven Bowen Basin mines (Goonyella Riverside, Broadmeadow, Daunia, Peak Downs, Saraji, Blackwater and Caval Ridge) and owns and operates the Hay Point Coal Terminal near Mackay. With the exception of the Broadmeadow underground longwall operation, BMA''s mines are opencut, using dragline and truck and shovel fleets for overburden removal.

Openpit, opencast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mines are used when deposits of commercially useful ore or rocks are found near the surface.
Openpit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of openpit mining. The removal of this material is known as stripping. The strippingpit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit

Openpit Mining Operations. Openpit mines are dug on benches that are between four and sixtymeters in size, depending on the size of machinery used to excavate. The walls of most openpit mines are dug at an angle and include steps to prevent avalanches from occurring inside the build site.
This mine is an open pit mine producing 5,000 tonnes ore and 5,000 tonnes waste per day. Rock characteristics for both ore and waste are typical of those of granite or porphyritic material. Operating conditions, wage scales, and unit prices are typical for western mining operations. All costs listed are in
This article presents cost models for open pit mines, which takes into account cost uncertainty. In this paper, cost uncertainty is considered as cost of under production, and cost of over production.

Recent incidents have occurred in several Bowen Basin Open Cut coal mines where flammable and toxic gases have been found in areas where normal mining activities are being undertaken. Flammable and toxic gases have been found emitting from blast holes, post blast areas and strata, including spoil dumps and accumulating in the bottom of pits during temperature inversion events.
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a ''pit'', and
Chaulya, Prasad, in Sensing and Monitoring Technologies for Mines and Hazardous Areas, 2016. Abstract. Opencast mining operations involve huge quantities of overburden removal, dumping and backfilling in excavated areas. A substantial increase in the rate of accumulation of waste dumps in recent years has resulted in greater height of the dump for minimum ground cover area and also
The Tagebau Hambach is a large openpit coal mine (German: Tagebau) in Niederzier and Elsdorf, North Rhine–Westphalia, is operated by RWE and used for mining lignite.. The mine is on the site of the ancient Hambach Forest which was purchased by RWE in 1978. They then cut most of it down and cleared it to mine. Only 10% of the forest area remains.
