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.

Open-pit mining Pit geometry. Deposits mined by open-pit techniques are generally divided into horizontal layers called benches. The thickness (that is, the height) of the benches depends on the type of deposit, the mineral being mined, and the equipment being used; for large mines it is on the order of 12 to 15 metres (about 40 to 50 feet).

Strip mining is the process of mining a seam of mineral by removing a long strip of overlying soil and rock. Strip mining is a practical type of mining when the ore body that is to be extracted is near the surface. Open-pit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow.

1.1.3.1 Open-pit mining Open-pit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clear-cutting or burning of vegetation above the ore deposit may precede removal of the overburden. The

during the calculation of shovel productivity as well as fleet production management for an open pit mine. In reference to the case study of Chilanga Cement production plant, this algorithm has proved to be an important tool in determining the overall cost of materials handling in

inversely proportional to pit width. 3. Set area (AJ is directly proportional to pit width. It increases as the pit width increases and is maximized at the largest pit. 4. In level seams and downhill spoiling of inclined seams, average swing angles at the key cut (ßkey) and main cut positions (ßmain) are directly proportional to pit width.

Occasionally, ore bodies sufficiently close to the surface made open pit or open cast mining practical. Often regarded as a twentieth-century approach, open pit mining was actually widespread earlier. It was a logical extension of placer mining, which excavated into sand bars any number of feet. Digging deeper resulted in pits, a practice
