Mining
Techniques is divided into two types: surface
mining and underground mining. Mining
targets are divided into two categories of materials: placer deposits
and lode deposits. If a mineral is stable chemically and is resistant
physically, it can be eroded from its primary hard-rock occurrence
and transported to river channels, deltas or other sedimentary
environments where it can be deposited in a sedimentary bed. Diamonds,
gold and other gemstones can be found in placer deposits. Lode
deposits are a very important source of precious metals, although
they also can contain base metals. Deposits like these are found
in greenstone belts, areas of metamorphosed volcanic or sedimentary
rocks. The deposits themselves can have almost any host rock,
but mafic volcanic rocks, felsic intrusive rocks and some sedimentary
rocks are the most common ones. Both types of deposits are mined
by surface and underground methods.
Some of the mining techniques are:
Alpha Hydraulic Diggings
Borehole mining
Box cut
Contour Mining
Deepsea mining
Dredging
Drift mining
Fire-setting
Glory hole (petroleum production)
Heap leaching
Hydraulic mining
In-situ leach
Landfill mining
Longwall mining
Mountaintop removal mining
Omega Hydraulic Diggings
Open-pit mining
Placer mining
Quarrying
Quartz reef mining
Retreat mining
Room and pillar
Shaft mining
Shrinkage stope mining
Slope mining
Strip mining
Sulfide mining
Underground mining (hard rock)
