Open Pit and Underground Mineral Production Activities ...

Combining open pit and underground mining. Either in the initial design stage, or before the end of the life of an open pit, a decision may be made to extend the life of the mine by exploiting the orebody below the economic level of open p it mining, by underground methods. Continuous production is essential, and the decision to go U/G must be made in time to complete access development so ...

Underground Mining - Mining and Geomorphology

When open pit mining, the most geomorphic intrusive mining method, is no longer cost effective, underground mining takes over (where possible). However, the damage has been done to the surface of the land. The underground mining method tends to continue this intrusive action by using a stope method. The stope method continues the geomorphic scar on the landscape by digging out cavities ...
