As markets continue to demonstrate significant volatility mining companies are examining radical new mining methods that can be applied to reduce personnel requirements and limit diesel fuel dependence and emissions One such method is the use of in pit crusher conveyors IPCCs IPCCs essentially replace a nbsp

Facility location models are rarely used in the mining sector but these models may be used for solving the in pit crusher location problem To this end the main parameters affecting the Haulage costs are always a significant part of capital and operating costs in large open pit mines According to Tutton 2009 in a typical nbsp

16 Feb 2017 In light of these challenges in pit crushing and conveying IPCC is a technology that has grown in popularity since it was first implemented in the 1950s The first and most obvious is a marked reduction in costs due to less need for road and truck maintenance along with significantly less fuel use and nbsp

12 Feb 2016 hours in Valuable Operating Time compared to the average Valuable Operating Time of 2 638 hours for the truck fleet The inference made from this observation is that the higher effective utilisation of a continuous haulage system for example In Pit Crusher Conveying IPCC could significantly improve the

becomes deeper Waste is hauled around the pit ends to minimise the change in elevation between dig and dump Marginal costs of mining deeper do not increase as rapidly Figure 2 Marginal Cost of Waste Removal for a Haulback Operation as in the previous model but are significantly above average costs at depth

The capital and operational cost directly depend on the material transport system Conventional truck haulage as today s predominant mean of material transport in surface mines are well established and provide excellent flexibility however contribute up to 60 of the overall mining cost IPCC represents a viable safer and nbsp

1 Jun 1985 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 article will discuss the effects nbsp
