Open Pit Mining an overview ScienceDirect Topics

Open-pit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow. Figure 8.8. Open-pit mine [16]. Surface mining is usually used to develop coal seams and deposits of many other minerals, but their feasibilities vary with the nature of the body ore.

Block caving: A new mining method arises Geoengineer

25/07/2018 Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight. It is the underground version of open pit mining. In block caving, a large section of rock is undercut, creating an artificial cavern that fills with its own rubble as it collapses. This broken ore falls

Optimization of blasting design parameters on open pit bench

In open pit mining where rock is hard such that ,it requires drilling and blasting techniques to be applied for it to be mineable, the overall cost-effectiveness of the production operations requires that drilling and blasting be optimized. Mining costs for unit operations which includes loading, hauling, crushing costs reduce with increasing rock fragmentation sizes. Quality of blast
