ACCESSING THE ORE BODY. Underground: Vertical shafts and decline ramps are sunk into the ground to transport people and equipment to and from deeplevel ore bodies (many are more than 1,000m below surface) and to bring the ore mined to surface. Open pit: Nearsurface orebodies accessed by "stripping" overlying material.

Let's review the key mining terms that are required to pull economic information from a technical report. Ore is rock that contains metal that is economic to mine and it's measured in metric tonnes. The grade is the amount of metal contained in the ore and is measured in .

In situ mining (see mining solution page) can be more environmentally friendly than underground mining and is cheaper than many mining methods (UlmerScholle, 2008). However, in situ mining cannot be implemented in all cases as the ore needs to be beneath the water table (the level at which the ground is saturated with water) and it needs to be ...
