Two main types of mines Open pit mining Roughly ten times lower in cost per ton compared to under ground mining Slope stability decide waste/ore ratio With low grades a high production rate is needed Big equipment for high volume production Under ground mining Under ground mines commonly have lower production rate Increased cost to infrastructure and ground support
Amankw, H. (2011). Mathematical Optimization Models and Methods for OpenPit Mining. Doctoral dissertation. ISBN . ISSN . Openpit mining is an operation in which blocks from the ground are dug to extract the ore contained in them, and in this process a deeper and deeper pit is formed until the mining operation ends.
