Surface mining, including strip mining, openpit 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.
Sep 19, 2011· Cost Reduction in Mining Operations Discussion The operating cost structures of mining operations globally have increased significantly over past years. When raw material prices are high it might appear to be an odd time to be thinking about cost reduction, but in fact it is the ideal time. History has shown us is that.

Despite all the investment in the South African coal mining sector, there is still little consistency in unit capital costs invested/required to develop coal mining projects. Lack of research within the area of coal mining projects'' costs is attributable to a lack of publicly available information. Research in
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 – a pit, and the ...

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 2012 US.
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.
Andrew Keith, Aurecon''s Mining Infrastructure Leader spoke with Australian Mining on the economics of pit to port transportation alternatives.. The ratio of infrastructure costs vs. equipment costs has dramatically shifted in the last decade.. Transportation costs make up some of the biggest outlays for a mining company. Choosing the right options can therefore make a big impact on a mine''s ...

Steffen, Robertson, and Kirsten (1989) list the following as sources of ARD from mining operations: Waste rock dumps from metal mines and spoil piles from coal mining, • Drainage from underground workings, • Surface runoff from open pit mine faces and pit workings, and Ore stockpiles and spent ore piles from heap leach operations.
In general, underground mining is more expensive than open pit mining as with open pit mining the minerals are found near the surface at a maximum of approximately 200400 meters depth in bulk tonnage.. The mining costs are estimated in a mining company''s feasibility study which, when available, can be found on the company''s website (often hidden between the news releases).
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.
