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. Open cast 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 .

Abstract: A dynamic sequencing method has been developed that can simultaneously optimize the final pit and the production schedule of an open-pit coal mine. The method first establishes a geological seam model of a bedded coal deposit which estimates the relevant attributes of coal seams at the center of each block on the X-Y plane.
The study uses data from completed coal mining projects from selected coal-producing countries. Three formulae are developed and presented for estimating capital costs of underground bord and pillar, surface shovel and truck, and dragline operations. Keywords coal mining.

Open-pit, open-cast 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 mining.Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface.
best mining design in coal mining open cast mine. We have specialist capabilities in the design of mines for a wide range of mining methods and commodities. Our mining services extend from pit to port, from the inception of brownfields and greenfields projects to the end of the mine development stage when production begins.
costs for modern, mechanized and open cast mines, to 50%–60% for the mature deep-level underground mines. Worker demands for increased salaries and wages have continued to plague the industry, and it is estimated that South Africa's mining industry lost more than US$1.4b in the 2012–13 financial year. While workers
