Open Pit Mining. Openpit mining is similar to traditional mineral mining operations and largely employed where oil sands reserves are closer to the surface (less than 75 metres underground). Currently, 20% of oil sands reserves are accessible via mining techniques. Large shovels scoop the oil sand into trucks which then move it to crushers where the large clumps of earth are processed. Once ...
