Underground Mining Methods - Mining Matters

backfill underground serves to keep the mine walls stable and also as the floor for mining the next slice. Mining continues upwards towards the surface until the ore body is depleted. Sublevel Caving Sublevel caving is usually carried out when mining of the ore body through an open pit method is no longer economically feasible.

Optimizing the Extraction Strategy for Open Pit and ...

The mining options could either be open pit mining or underground mining or simultaneous open pit and underground mining. The NPV of the production schedule is maximized in the presence of technical, geotechnical, geological, and economic constraints to enforce the mining extraction, blending requirements, and mining and processing capacities. 162

Strategic mining options optimization: Open pit mining ...

01.11.2016  From preliminary underground mining studies, a selective underground mining method known as long hole open stoping was identified as a potentially viable underground mining method. The production schedule for a combined open pit and underground mining scenario requires that both mining options compete for the same reserve during optimization.

Underground Mining Transportation Haulage Systems

01.04.2017  Another underground conveyor belt that was also used in connection with open-pit mining operations was installed at the New Idria mine. This is probably one of the earliest installations in an underground metal mine. It was employed principally to convey waste from the hanging wall of the ore deposit to a waste dump. The waste is blasted or caved into a raise

OPTIMIZATION OF PRODUCTION PLANNING IN UNDERGROUND MINING

In underground mining, development required to reach the orebody is much and increases the production time from the start of the development (Haycocks, 1992). Effective mine planning is required to generate profit (Carlyle et al., 2001). Mine production scheduling is an important problem in mine planning (Gershon, 1983). Main objective of the production scheduling is to
