There are two principal phases of underground mining: The ore is fed down ore passes, with mining equipment accessing the ore body via a decline from surface.
Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, and machinery in and out, of underground mines.
Underground mining is approved out when the rocks, minerals, or gemstone are positioned at coldness far beneath the ground to be extract with outside mining.

1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately.
Uranium; How is it Mined? What Is Uranium? The milling process involves crushing and pulverizing the rock into very fine fragments and Underground Mining:
For both traditional underground and open pit mining, the rocks may have only a few percent (normally lt;0.3%) uranium in them. The uranium then has to be removed from the rock and concentrated. The milling process involves crushing and pulverizing the rock into very fine fragments and adding water to create a slurry.
