The open-pit or open cast mining method is the obvious choice for a property with wide area of mineralization exposed or exists close to the surface and continues to greater depth. The open pit is opening the orebody from the surface by separate removal of ore and associated waste rocks.Open-pit mining Wikipedia,Open-pit mining, also known as open-castor open cut mining, is a surface miningtechnique of extracting rockor mineralsfrom the earth by their removal from an open-air pit, sometimes known as a borrow. This form of miningdiffers from extractive methods that require tunnelling into the earth, such as long wall mining.

Key words: Open pit mining, bench height, multi-criteria decision making. INTRODUCTION As a definition in open pit mining, bench height is the vertical distance between crest and toe of the bench (Fourie and Dohm, 1992). Determination of optimum bench height is a major concern in most open pit mines.Mining and Refining Process,Bauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the location. Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which

Surface mining Wikipedia
Surface mining, including strip mining, open-pit 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.An Introduction To Surface Mining,However, surface mining can be more environmentally-damaging than subsurface mining.

Mining: The process of taking out minerals buried under the rocks is called mining. There are two main methods of mining, viz. open-cast mining and shaft mining. Open Cast Mining: When minerals are taken out by removing the surface layer, the process is called open-cast mining. Minerals which lie at shallow depths are extracted by this process.Basics of an open pit mine Mine Engineer.Com,Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
