The operation quality of shovel-truck systems (STSs) at open-pit coal mines in the summer and transitional autumn-spring periods differs markedly. This is due to a decrease speed haul trucks during season compared season. leads an increase travel time trucks. Shovels must work longer ensure planned volumes loading transportation required number hauls. Consequently, duration working shift (or da...

One of the most challenging aspects in semi-mobile in-pit crushing and conveying (SMIPCC) system design is determining optimum depth at which to change from a purely truck-based haulage conveyor-based system. We used scenario analysis determine transition between truck shovel (TS) SMIPCC Traditional pit-limit algorithms were generate final pit limit on copper deposit, was then divided into four...

Transportation costs are a significant part of capital and operating costs of large open pit mines. Cost efficiency and high reliability of in pit crushing and conveying systems compared to conventional truck-shovel system makes it more appealing to be utilized in modern mining activities. In this paper the suitable location of an in pit crusher is investigated as a single hub location problem....

The dispatch of trucks and shovel has always been an important component in the success of open pit mine operations. Dispatch systems have evolved from manual to today automatic with almost no human intervention. Although dispatching systems available today are “pseudo real time” and efficient, the optimal dispatching is realized over subsets of the fleet when dealing with large fleets. This ap...

The shovel-truck system is commonly used in open-pit mining operations. Truck haulage cost constitutes about 26% of costs as the trucks are mostly powered by diesel whose escalating annually. Therefore, reducing fuel consumption could lead to a significant decrease overall costs. Various methods have been proposed improve efficiency mines. Case-based reasoning (CBR) can be estimate trucks. In t...
