Attempting to apply an existing design of sizer or transfer conveyor to a new operation without considering all relevant issues is unlikely to provide the best solution. Of paramount importance is understanding and acceptance of the system by the operating team that will eventually have to make it work. The best design and delivery of an IPCC system will count for little if the operating reason, do not adequately understand the issues that influence production.

What Needs to Be Considered for IPCC Systems

This article seeks to document the technical and economic factors in particular that should be considered in assessing the suitability of different IPCC systems, with a focus on pit equipment layouts. These factors include the productivity of the systems, interactions with the drill/blast and bench operation sequence, ease of relocation, flexibility to changes in the reserve, scalability and compatibility with other elements of the system.

Whilst providing examples of responses to some of these issues, this paper does not seek to promote a particular solution. An argument is made instead that the appropriate IPCC system for a specific operation cannot be selected without consideration of a wide range of site specific factors.

Criteria's for Successful IPCC Application

An IPCC system must satisfy two competing criteria in order to be the most appropriate selection for a given operation:

be physically able to excavate and deliver material (whether ore or overburden) to some form of out-of-pit system at the required capacity, and

be acceptably cost-effective during both the capital and operating phases of the operation.
