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.

The road barriers may be used at either end of the road for this purpose. Repair & Maintenance of Gravel Roads.

Description. Sand and gravel deposits found on beaches or in rivers and streams, are mostly quartz (silicon dioxide, SiO2) grains. Weathering of rocks such as granite forms these quartz grains. In the process of weathering, the softer, weaker minerals in granite (such as feldspar) are weathered away. The more resistant quartz eventually is ...

Mining haul roads are a critical component of surface mining infrastructure and the performance of these roads has a direct impact on operational efficiency, costs and safety. A significant proportion of a mine's cost is associated with material haulage and well-designed and managed roads contribute directly to reductions in cycle times, fuel burn, …

According to Clark, when building remote gravel roads for timber, oil, mining projects, the cost of hauling in gravel can quickly escalate the cost. "The farther away the road from the pit, the higher cost; and the more remote the road, the fewer the pits," Clark said. "That's when your price/mile of gravel road goes through the roof."
