open pit method of mining bitumen

  • Surface Mining Techniques used in the Oil Sands Oil

    Surface mining is defined as the extraction of ore from an open pit or burrow. Surface mining is sometimes known as open-pit, open-cut or open-cast mining and is only commercially viable if the deposit is located relative close to the surface. Less than 20% of Alberta's bitumen reserves are close enough to the surface to be mined.

These benches are usually on four to sixty meter intervals, depending on the size of the machinery that is being used. Many quarries do not use benches, as they are usually shallow.Most walls of the pit are generally dug on an angle less than vertical, to prevent and minimize damage and danger from rock falls.

    Open-pit, open-cast or open cut 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 tunnelling into the earth, such as long wall mining.Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface.

Like most surface mining operations, the oil sands are scooped by large shovels into trucks and taken to crushers where the large clumps of clay are broken down. The oil sands are then mixed with hot water so they can travel through a pipeline to a plant where the bitumen is separated from the other components.Tailings ponds are an operating facility common to all typ.
