    Mining in the Boreal Tar Sands Global Forest Atlas

    A key area of controversy over mining in the boreal region is the exploitation of tar (or oil) sands, which are areas with sand or sandstone saturated with bitumen, a viscous form of petroleum, which can be mined and processed to produce oil. Tar sands are extracted by either surface (open pit) mining or insitu extraction. For surface mining, areas are first cleared of trees, bogs are drained

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

    There are two primary extraction methods for oil sands: openpit mining and insitu mining. The technique used depends on the depth of the deposit. For example, insitu mining is used when bitumen lies too deep beneath the surface for openpit mining. Injection of steam is used in both methods to heat the bitumen, which serves to make it more
