Why the Pilbara leads the way in haul
A presentation at last month’s AusIMM Iron Ore 2019 Conference, in Perth, Western Australia, made it clear that the state’s steel raw material miners are leading the way when it comes to applying autonomous haulage systems (AHS) in open-pit mining.

The Mining Process – Waihi Gold
The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

The production cycle of open-cast coal mines generally includes drilling, blasting, loading, hauling and coal preparation activities. Individual optimization of these activities does not mean that the whole system is optimized. This paper proposes a cost model considering all activities in mining cycle and system-wide approach to minimize the total mining cost of bench production. Since the

In-pit crushing and conveying saves more than just fuel
Operational costs, worker safety and CO2 emissions are challenges faced by most mines and quarries today. While there certainly isn’t a silver bullet that would solve all problems overnight, in-pit solutions, such as in-pit crushing and conveying (IPCC) are widely recognized as a good place to start.

Modelling of In-Pit Crusher Conveyor alternatives: Mining
Abstract. As open cut mines become progressively deeper, mining operations face increased operating costs and technical challenges. In-Pit Crusher Conveyor (IPCC) systems offer advantages in the form of continuous operation, reduced labour requirements and decreased energy consumption resulting in lower cost per bank cubic metre.

For example, if the open side setting of the underground jaw crusher is 6 inches, then the d80 product size = 5¾ inches. Source: Unknown
