For open pit mines taking shovel-truck system as a major stripping system, the overburden transport costs can be accounted for 1/3 or more open pit operating costs. Therefore, shortening transport distance to reduce transport costs has become an important problem in nearly horizontal open pit mine.

Abstract. As open cut mines become progressively deeper, mining operations face increased operating costs and technical challenges. In-Pit Crusher Conveyor (IPCC) systems offer advantages in the form of continuous operation, reduced labour requirements and decreased energy consumption resulting in lower cost per bank cubic metre.

• In a hard rock mine, the product from a jaw crusher to feed a conveyor belt will have a size distribution such that the -80% fraction size is slightly less than the open side setting of the crusher. For example, if the open side setting of the underground jaw crusher is 6 inches, then the d80 product size = 5¾ inches. Source: Unknown

Mt Whaleback is one of the largest open-cut iron ore mines in the world. Haulage cost is the single largest component of operating costs at the mine. Past studies towards alternatives to truck haulage have recognised the potential viability of an in-pit crushing and conveying system, dependent on the proportion of uphill haulage.

The depth of the open pit mines have increased considerably over the last several years. In fact, there are some open pit mines that are reaching a depth of more than 1000 meters. Currently, the use of conventional trucks for transporting material is probably one of the most flexible systems in open pit mines.

The vendors indicate the conveying system should be able to achieve heights of 700 metres. This may facilitate the use of internal shafts (winzes) to hoist ore from even greater depths in an expanding underground mine. It may be worth a look at your mine.
