Otherwise, the failure of backfill column into adjacent stope(s) leads to higher operation cost (e.g., cost of ore milling/ore processing operation, costs associated with ore dilution when waste/backfill material mixed with unmined block(s)). Consequently,

Stability Analysis of Ore Passes In the Kiirunavaara Mine ...

2003-9-8 · In the Kiirunavaara underground mine, crude ore is transported through ore passes from the production levels to the main haulage level. Failure and stability problems have occurred in some of these ore passes, with increasing frequency as mining depths increase. In this paper, selected results are presented from a research project run by LKAB.

Should we worry at moderate risk to ground stability in ...
