In situ oil sands mining - Energy Education

This is known as in situ oil sands mining. Oil sands deposits are usually split into two types of deposits. Shallow deposits are located within approximately 75 meters of the ground surface and are extracted using surface mining methods. Deep deposits are located at least 75 meters below surface level.

Environmental Risks of Mining

Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.
