Transport systems create a large share both in the initial investment costs and in the operating costs of open pit mines. The main competitive transport systems to be used in larger mines - the discontinuous material transport by trucks and the continuous material transport by belt conveyors - are compared.

In open-pit mining, shovels (excavators) and trucks are the most widely used equipment, because material handling (mainly excavation with haulage) is the most important mining operation. According to previous studies, material handling accounts for nearly 50% of the total operating cost in most open-pit mines.

In open pit mining two different options for extracting and hauling material have been established. On the one hand, shovel and truck only, and on the other hand, in-pit crushing and conveying (IPCC). Energy efficiency and minimising operation costs are the main decision factors when choosing mining technology.

Abstract In-pit crushing and conveying (IPCC) systems have attracted more interest among miners as an alternative to the conventional truck-shovel transportation system. The semi-mobile IPCC (SMIPCC) system is a well-suited type of IPCC system in open-pit mining projects because of its relocation nature. However, it is very important to design …

Mining of raw materials is a process that consists of several stages. In open-pit mining, material with high compressive strength is extracted by drilling and blasting and material with low compressive strength is extracted by e. g. a bucket wheel excavator. Most important influencing factors for crusher decision are compressive …
