Openpit mining is used when the orebodies are extensive and relatively close to the surface. The sterile/ore ratio is one of the factors which defines the exploitation method and the final dimensions of the mine cuts. In general, openpit mining consists of a system to exploit open pits with multiple benches.

Mining Mining Surface mining: It has been estimated that more than twothirds of the world''s yearly mineral production is extracted by surface mining. There are several types of surface mining, but the three most common are openpit mining, strip mining, and quarrying.
Openpit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. Openpit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels. This surface mining technique is used when mineral or ore deposits are

Mar 13, 2012 · What is Opencast Mining• Opencast mining is also known as Open pit mining, Open cut Mining, Surface or Strip Mining.• The coal upto economical depth will be excavated by OC Method.• The current operating depth of OC mines in SCCL is about 200m and SCCL proposed to operate OC mines upto a depth of 420m. Ex: MNG OC II Extension Project.•
The surface mining can be classified depending on the loion of the deposit or the type of mining method. Generally speaking, we can classify surface mining in three main typologies that are open pit, open cast, and quarry. Open pit refers to the exploitation of a deposit outcropping to the surface
The openpit 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.
Openpit mining occurs on surface and is generally the cheapest way to extract ore. This is because rock doesn''t have to be moved far up hill against gravity, equipment used can be larger than underground, and it doesn''t require more expensive features like ventilation, communiions, etc. that underground does.

A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including openpit, stripping, dredging and mountaintop removal.
Open pit mining or strip mining is an extraction process for ore or fossil fuels that takes place at the surface of a mining site. Worldwide, 40 percent of mining occurs at the surface, according to Greenpeace International. Compared with underground mining, surface mining is much more efficient.
Openpit mining is the most common type of surface mining. An openpit mine is exactly what the name implies: a big hole (or pit) in the ground. The pit in an openpit mine is created by blasting with explosives and drilling. This type of mining is typically used to mine gravel and sand and even rock (when openpit mining is used to extract
