    Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Reviews: The book emphasizes the stability of the rock slope itself in open-pit or strip mines, but also considers the stability of waste rock embankments, tailings dams, and heap leach facilities. 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 -pit mines are used when deposits of commercially useful ore or rocks are found near the surface.

The open pit is opening the orebody from the surface by separate removal of ore and associated waste rocks. It is the most economic option for a deposit up to that depth where the economic ratio of ore and waste can sustain.

There are many advantages in open-pit mining method namely: Full visualization of exposed orebody and negligible ore loss. Deep open pits are becoming increasingly common in the mining industry and the consideration of the design of slopes in open pit mines is a classical problem for mining engineers.

Many of these pits are being developed in parts of the world where deep weathering has taken place, producing deep deposits of residual soils. However, limited.Book a Demo.
