(PDF) Open Pit Coal Mine Design Mohammad Lashgari ...

When an ore body is steeply dipping and at or near the surface, open-pit mining can start with a small amount of stripping. However, as mining of such a deposit progresses, increasing amounts of waste rock must be removed. This must often be done many years before mining of the corresponding amount of ore at deeper levels can take place.

Operation designed to extract mineral deposits that lie close to the surface. It is used when the orebody is near the surface and little overburden (waste rock) needs to be removed. Large hole exposes the ore body. Waste rock

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
