The market of open-pit dump trucks in Russia features a large number of different producers. Many of them offer open-pit dump truck in almost all loading capacity classes. At the same time, open-pit dump trucks of different producers are characterized not only by the price but also by the design features, including overall dimensions.
However, the scope to continue introducing larger and higher capacity trucks and equipment into mining operations in order to improve productivity is limited. Truck haulage is a highly energy, labor and water intensive operation. ... However, in maintaining a limited truck haulage distance to an in-pit crusher, the initial pit depth is limited ...
An in-pit and mobile crusher facilitates the transport of crusher material (ore, stone, rock) out of the mining area via also mobile or portable conveyors. ... This separation of the crusher unit from the digging area is dictated by the high crusher capacity required. If the crusher unit operated in the digging area, the shovel or front-end ...

With the trend of open pits becoming broader and more profound in scale continuing, the potential of In-Pit Crusher and Conveyor (IPCC) systems to save costs deserves new tools to make the study of its practical comparison against more traditional truck/shovel systems more accessible and feasible. In recent years, the interest in and research ...
In-Pit Crushing and Conveying (IPCC) systems are receiving more attention today due to current characteristics of open-pit mining operations and what is expected to occur in the future. Today, it has become more necessary …
A case study that performed simulations on shovel-truck haulage systems in an open-pit mine by considering truck's breakdown and crusher's capacity showed that 7 trucks can maximize the daily profit of haulage operations. This paper presents a case study that performed simulations on shovel-truck haulage systems in an open-pit mine by considering truck's …

The suggested reserve capacity for quarry operations applies as well to open-pit mining operations employing power shovels for loading the ore. Usually the original crusher is expected to produce the required daily tonnage in such plants in one or two shifts, so a time-reserve does exist which can be utilized to make up for delays.
