mine design, scheduling, and reporting processes. This, incidentally, is the way production personnel would view a plan. They don't get bogged down in looking at the longterm plan, at the panel level of detail. They look rather at areas available and the number of crews that would be used to extract an area.

Two techniques of extractions are used: Block Caving: block caving is an inexpensive method of mining in which large blocks of ore are blasted, causing the ore to break or cave under its own weight. This method is largely depending upon the action of gravity and is considerably less expensive than the traditional method of mining copper porphyry deposits.

A disadvantage to this method is that it can leave a large amount of mineral in place. Longwall mining allows for increased mineral extraction to occur, since it shears entire blocks of mineral onto a conveyor belt through the use of selfadvancing, hydraulic roof supports or shields.

In all of these processes, the most important considerations are the economics of the processes and this is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur.
