PDF Primary crusher site selection in open pit mines Case
·Facility site selection such as Primary or in pit Crusher location is one of the most important steps in mine design process that has a significant impact on economy of the mining operation

·The SMIPCC is a system where the in pit crusher is located in the pit and is relocated after 1 2 years depending on the operations of the specific mine Tavakoli et al 2011; Hay et al 2019 The SMIPCC is characterised by a crusher station located not more than 2 km from the mine face operations depending on the size of the open pit mine
·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
The proposed model diverges particularly from others by considering the existence of a belt conveyor layout that represents the possible transportation system of the
Backgrounds The transportation system within any mining project which is responsible for delivering extracted ore to the crushing units or wastes to the wasting dumps as the destinations poses a significant challenge in mining processes On one hand there are various transportation systems notably the Truck Shovel the traditional method and relatively newer and less

·Using an in pit mobile crusher can reduce the haulage costs but due to high initial investment cost this option has not been considered Instead changing the location of the crusher screening plant during the operational period by uninstalling and installing the plant has been studied Utilizing the crusher at a stationary position without
·haul distance by bringing the truck dump point into the pit Using an in pit movable crusher or crushers and conveying the ore and/or waste out of the pit can reduce the haul costs The potential effects of installing in pit crushing and conveyor haulage on open pit operations and on mine planning requirements can be significant This
·In pit crushing and conveying IPCC systems are used in open pit mining for their potential economic environmental and safety advantages An in pit crusher is closer to the point of excavation and requires less total truck haulage than a fixed ex pit crusher A semi mobile system allows the in pit crusher to relocate up to once per year
