When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited. This equipment can include the following: Draglines which ...

Dec 21, 2018 Due to the limitation of the mining process in opencast mines, thin coal seams that are below the desired level of seam thickness for mining sometimes cannot be mined and the volume of that coal is considered as waste volume. Using GEOVIA Minex, this waste coal volume can be calculated and an estimation of the waste volume can be performed ...
however, for large-scale open pit mining in particular, the \truck and loader" material movement practice is the preferred method of materials handling (Czaplicki, 1992; Ta et al., 2005). Throughout this paper, we consider a \loader" to be any type of high productivity excavating equipment, which may include a mining loader, shovel or excavator.

Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.. Surface mining began in the mid-16th century [dubious ...
3.6.4 Losses During Mining. Mining of coal is undertaken broadly using two methods: surface and underground. In the case of underground mining, losses are high compared with those of opencast mining; the main causes of these losses are enumerated in the following subsections. 3.6.4.1 Opencast Mining
