May 01, 2016 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 Albertas bitumen reserves are close enough to the surface to be mined.
Since nearly half of the open pit surface mines in the U.S. produce sand and gravel aggregate, lots of questions tend to come up about the equipment used in that type of mining. As you can imagine, it takes a range of both mobile and stationary equipment to run a sand and gravel operation.
