Open-Pit Mining MethodsOpen-pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. The removal of this material is known as stripping.

Oil Sands - 2B1st Consulting– Open-pit-mining if the deposit is on the surface – In-situ or drilling if the deposit is stocked underground as conventional crude. The method is selected in respect with the depth of the reserves. In Canada about 3% of the 140,000 square kilometers of land contain mineable deposit, the other 97% will require the in-situ approach.
Reading: Open-Pit Mining - Geosciences LibreTextsOpen-pit mining, or open-cast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining.
