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. It is applied to ore or rocks found at the surface because the overburdenis relatively thin or the

This article presents cost models for open pit mines, which takes into account cost uncertainty. In this paper, cost uncertainty is considered as cost of under production, and cost of over production.

Change in production and productivity of US coal mines The higher productivity for open pit mining equipment also lowers costs.

Open pit mining does offer some advantages over traditional deep shaft mining. Pit mining is more cost effective than shaft mining because more ore can be extracted and more quickly. The working conditions are safer for the miners because there is no risk of cave in or toxic gas. Open pit mining

Welcome back to the surface mining model. In the previous topic, we learned about different types of surface mining operations, about equipment, about different methods that are commonly used to extract coal or different ore deposits. It’s not difficult to understand that mining is one of the most dangerous working environments in the world and in this topic, we will go through some of the

however, for large-scale open pit mining in particular, the \truck and loader" material movement practice is the preferred method of materials handling (Czaplicki, 1992; Ta et al., 2005). Throughout this paper, we consider a \loader" to be any type of high productivity excavating equipment, which may include a mining loader, shovel or excavator.
