Although open pit mining (link to mining solution page) contributes about 85% of all mineral mining, it is one of the most environmentally taxing. About 73% of extracted rock goes to waste. Meanwhile, underground mining wastes only 7% of the extracted rock but is more expensive (Hartmann and Mutmansky, 2002). In situ mining (see mining solution page) can be more environmentally friendly .

In open pit mining, thick seams (tens of meters) are mined by traditional quarrying techniques. Underground mining is used for deep seams. Underground mining methods vary according to the site conditions, but all involve the removal of seams followed by more or less controlled subsidence of the overlying strata. Raw coal may be sold as mined or may be processed in a beneficiation/washing plant ...
Hard Rock Miner's Handbook is a work of the heart. Jack—whose 40+ year career spanned engineering, construction, and operation of mining projects worldwide—conceived of and wrote the first edition of the Handbook, published in June 2000, to assist miners and engineers in the difficult world of hard rock mining. It was his gift to an industry that provided him with employment, challenges ...
Openpit mining, also known as opencast mining, opencut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from extractive methods that need tunneling into the earth.

Sublevel Open Stoping originated in the early 1900's in iron ore mines in Michigan, USA. It was developed over the years from a method originally known as short hole bench and train a large scale open stoping method, it is often referred to as long hole or blast hole stoping. A Typical Sublevel Open Stoping Operation.

produced depends on the type of mineral extracted, as well as the size of the mine. Gold and silver are among the most wasteful metals, with more than 99 percent of ore extracted ending up as waste. By contrast, iron mining is less wasteful, with approximately 60 percent of the ore extracted processed as waste (Da Rosa, 1997; Sampat, 2003). Disposing of such large quantities of waste poses ...

People in few of the Englishspeaking countries are not likely to make a difference among an openpit mine and other kinds of opencast mines, like quarries, borrows, placers, and strip mines. Openpit mines are characteristically engorged until either the mineral resource is exhausted, or a mounting ratio of overburden to ore makes more mining uneconomic. When this occurs, the exhausted mines ...
