Coal mining and transportation U.S. Energy Information

Transporting coal. Coal can be transported from mines and processing plants to consumers in several different ways: Conveyors, trams, and trucks move coal around mines, for Restrepo et al. (2015) conclude that the major contributor to acidification potential in coal mining is the use of explosives. Koornneef et al. (2008) find that 80% of overall acidification potential is attributed to the use of sulfur containing diesel for ship transportation of coal. Further analysis is needed to reach definite conclusions inCase history of environmental impacts of an Indonesian coal

Determination of semi-mobile in-pit crushing and conveying

The SMIPCC is a system where the in-pit crusher is located in the pit and is relocated after 1–2 years, depending on the operations of the specific mine (Tavakoli et al. 2011; Hay et al. 2019). The SMIPCC is characterised by a crusher station located not more than 2 km from the mine face operations depending on the size of the open-pit mine.In large coal preparation plants with a capacity of 30 million tons/year, the belt speed can reach 7 m/s and the thickness of the material layer can reach 500 mm. Therefore, in high-throughput and Feeding Material Identification for a Crusher

Energy consumption in open-pit mining operations

In a coal mine in India, the excavators, draglines, and shovels were measuredly consuming 32.64, 23.2, and 3.84 MJ of energy per ton of ore. Because the crusher is installed inside the mining pit, the trucks transport the minerals to the crusher at a shorter distance. Also, in this scenario, the trucks do not transport the crushed mineralsIn order to improve the automatic control effect of fully mechanized mining face in coal mine, this paper combines the literature research method to analyze the disadvantages of traditional research and combines the demand analysis to analyze the structure of the automatic control system of fully mechanized mining face in coal mine.

The fixed system's function is not very dissimilar to that of a traditional truck/shovel system, only that the crusher is fixed for the length of mine near the pit crest, which ferries crushed ore via conveyor to the mill. The other studied case is a semi-mobile crusher. This crusher requires infrastructure and is large and difficult to move.
