Mining Techniques

Mining techniques can be divided into two basic excavation types:

1. Surface mining

* Open-pit mining
* Quarrying
* Strip mining
* Placer mining
* Mountaintop removal



2. Sub-surface mining

* Drift mining
* Slope mining
* Shaft mining
* Hard rock mining
* Borehole mining
* Drift and Fill mining
* Long Hole Stope mining
* Sublevel Caving
* Block Caving
* Shrinkage Stope mining
* Room and pillar
* Longwall mining
* Retreat mining

In-situ leach is a particular mining technique that is used to mine minerals (potash, potassium chloride, sodium chloride, sodium sulphate and uranium oxide) which dissolve in water.
