A surface mine contains pits with mineral endowed rock or ore. We extract ore that lies within the upper layer of the earth, from surface mines Fricke, 2006 . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal.
Aug 30, 2020 Opencast mining or quarrying of minerals is easier than mining by underground methods. During quarrying the and rocks below which the minerals lie, are removed and in the initial stages, in a place which is not required in future g, residential or other purposes.

Dec 12, 2018 The production cycle of open-cast coal mines generally includes drilling, blasting, loading, hauling and coal preparation activities. Individual optimization of these activities does not mean that the whole system is optimized. This paper proposes a cost model considering all activities in mining cycle and system-wide approach to minimize the total mining cost of bench production.

The mining process has recently been changed from the age old underground mining process to the open-cast mining process. The main advantage in open-cast mining is that it is much more safer and, at the same time, the rate of coal production per day is
Opencast mining is also known as open-put mining, open-cut mining, surface mining and also as strip mining, the later term being commonly used in the U.S.A. for opencast mining of coal. The overburden and the mineral, coal, are excavated in long strips of a few metres thickness and hence the operations are termed strip mining.

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.
