As an alternative to traditional truck and shovel mining, in-pit crushing and conveying systems are attracting global interest for their sustainability benefits and potential to reduce operating costs. The selection of the most appropriate solution for a given operation must consider economic, social, environmental and technical issues.

In-pit crushing and conveying (IPCC) systems have come under growing scrutiny as a perceived mitigation to fuel and equipment price fluctuations, labour shortages and the need to move ever-increasing volumes of material. Individual vendors and delivery organisations are now offering a sometimes confusing array of systems, particularly for the dig and dump side operations.

One system does not suit all operations. This article seeks to document the factors that should be considered in assessing the suitability of different IPCC systems, with a focus on dig side equipment layouts in particular. These factors include the productivity of the systems, interactions with the drill/blast and bench operation sequence, the ease of relocation, flexibility to changes in the reserve, scalability and compatibility with other elements of the system.

In–Pit Crushing and Conveying Bench Operations

In-pit crushing and conveying (IPCC) or ‘truckless’ systems have come under growing scrutiny as a perceived mitigation to fuel and equipment price fluctuations, skilled labour shortages and the need to move ever-increasing volumes of material. Individual vendors and delivery organisations are now offering a sometimes confusing array of systems, particularly for the dig and dump side operations.

Truckless Mining – Chance or Risk?

There is an abundance of claims regarding the potential advantages of IPCC systems, yet working installations and projects in active development beyond the study phase do not necessarily match the hype.

Assessing the truckless mining option In-pit crushing and conveying bench operations Despite the trend towards ‘off-the-shelf’ offerings from the market, one system does not suit all operations. The selection of the most appropriate materials handling system for a given operation must consider economic, social, environmental and technical issues.
