#0183;#32;Mining is a complex, expensive, yet lucrative business. Todays openpit mines are huge projects in Australia. To keep the projects profitable, planners and schedulers are under constant
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. Openpit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow.
mining cost depth escalation factor is currently US cents per bench (bench height is 14 m). Processing costs The Letseng processing plants are also contractoroperated. Treatment costs comprise the contractor labour rates, power, spares, and consumables per ton. The mine planning process for an openpit diamond mining operation
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. In a hard rock mine, the bottom of the pit would be the lowest level (elevation) that mining would be conducted on the ore being mined.

An Overview of the Open Pit Mining Process Openpit mining which is sometimes referred to as open cut mining, opencast mining or simply strip mining is a mining technique that extracts important minerals from a borrow or an open pit. There are two types of mining methods commonly used in large scale mineral mining; open pit mining and tunneling.
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.

2. 2 Introduction Open pit mining is the process of mining a near surface deposit by means of a surface pit excavated using one or more horizontal benches. The term open pit mining is usually used for metallic or nonmetallic deposits and sparingly used for bedded deposits like coal.
