Surface Mining Techniques Used In The Oil Sands Oil
Surface mining strip mining: although sometimes mistakenly referred to as strip mining, oil sands is actually mined from an openpit below several meters of overburden.Strip mining is the mining of a relatively flat deposit very close to the surface, commonly used in coal or phosphate industries.
Oil Sands Surface Mining Energy Education
Surface mining is a technique used to obtain bitumen from oil sands where the oil sands deposits are located fairly close to the surface.If the reserves are shallow enough, earth moving equipment can dig out oil sand for processing.These deposits must be within 75 meters of the surface to be mined in this fashion.Resources recoverable by this type of extraction are estimated to be 65.
Underground Mining Methods And Equipment
