Open-pit mining is similar to traditional mineral mining operations and largely employed where oil sands reserves are closer to the surface (less than 75 metres underground). ... Once the oil sand is crushed, hot water is added so it can be pumped to the extraction plant. At the extraction plant more hot water is added to this mixture of …
Ecological protection in the process of open-pit coal mining is an urgent problem in arid mining areas. Achieving the self-sustenance of the restored ecosystem, a new ecological balance, and sustainable development through positive succession are the main processes that need further study (Bian et al., 2022; Coban et al., 2022).

In order to solve the serious dust pollution problem in mining and loading process of burnt rock open-pit coal mines, a dust suppression technology was proposed to investigate the compound dust suppressant with four functions of wetting, coagulation, moisture absorption, and moisture retention, and improve the hydrophilicity and dust suppression efficiency of …
Coal in the seam is then excavated. Surveyors are present to ensure the coal is mined optimally. The coal is blasted into smaller layers, which are dug up and transported by trucks to a processing plant. Throughout the coal mining process, we minimise the impacts on the environment including the air and water quality, noise and heritage sites.
Vegetation and soil restoration are the key to ecological reconstruction in the damaged areas of open-pit coal mining areas. Ecological stability is an important indicator of the degree of ecological restoration. In this study, the ecological stability and the process of plant and soil restoration were investigated at different refuse dumps in three coal …
Coal is a non-clastic sedimentary rock.They are the fossilized remains of plants and are in flammable black and brownish-black tones. Its main element is carbon, but it can also contain different elements such as hydrogen, sulfur and oxygen. Unlike coal minerals, it does not have a fixed chemical composition and crystal structure.Depending …
Surface mining is defined as the extraction of ore from an open pit or burrow. Surface mining is sometimes known as open-pit, open-cut or open-cast mining and is only commercially viable if the deposit is located relative close to the surface. Less than 20% of Alberta's bitumen reserves are close enough to the surface to be mined.
The Pingshuo mining area is located in Shuozhou city, northern Shanxi Province (Fig. 1), in the eastern part of the Loess Plateau.The Pingshuo open-pit coal mine is the largest open-pit coal mining area in China, covering an area of approximately 400 km 2 and comprising the Antaibao, Anjialing and East open-pit mines, with geological …
The approximate 3.0 million tonnes per annum (Mtpa) of run of mine (ROM) coal from the west pit will be scalped, removing the coarse parting and waste, and the resulting approximately 2.0Mtpa of coal will be transported by road to the Vele Colliery for further processing. The Vele plant modifications will facilitate the simultaneous production ...
Areas for open-pit mining are selected using the mine plan. Identified areas are tagged, and then holes are drilled in an appropriate pattern by rigs. The drill holes are filled with an explosive, most often ANFO (Ammonium Nitrate/Fuel Oil) and then charged. The resulting blast breaks the material to a size required for digging. Load and Haul
The process is repeated in successive parallel cuts until the stripping ratio indicates that continued surface mining is uneconomical. Open-pit mining. In open-pit mining of the coal seam, several benches are established in both the overburden strata and the coal seam. The open-pit method is generally practiced where thick coal seams are ...
We consider both direct block scheduling and bench-phase scheduling problems, with capacity, blending, and minimum production constraints. Using new …

Open-pit mining is a type of surface mining used to extract coal, gold, and other minerals. It creates immense water and air pollution, disfigures landscapes, and destroys habitats.
Coal Mining Process. The US burned roughly 700 million tons of coal in 2016—enough to fill a standard railroad car every 4 seconds. 90% of that coal consumption went into the generation of electricity, while the rest (just 10%) was burned for other industrial/commercial requirements. All of this coal comes from mines that are either …
Mining. Coal is extracted by two principal methods, of which there are many variants: surface mining or subsurface mining. Surface mining uses large machines to remove the soil and layers of rock known as overburden to expose coal seams that are close to the Earth's surface (figure (PageIndex{a})).Strip mining is a type of surface mining in …
