Minimising Energy Consumption in Mining

Minimising energy consumption is crucial to the mining industry’s ongoing objective to become more sustainable. However, the pressure to meet daily operational targets often leads to inefficient energy usage and increased costs.

There are several technologies targeted at reducing both energy consumption and emissions during mining activities, such as diesel-electric vehicles, which are equipped with electric systems that monitor and limit diesel usage.

Electrification is picking up a lot of momentum in the mining industry, with many companies integrating lithium-ion battery-powered vehicles into operations. Digital twin technology is also being widely deployed by mining companies as a way of tracking and optimising the energy consumption of physical assets and equipment.

Minimising energy consumption is particularly important in underground mines, where mine vehicle diesel exhausts, combined with poor airflow, compromise worker safety.

While preserving air quality is easily done through ventilation systems, these consume huge amounts of electricity and drive up costs. Two key innovations that have optimised ventilation in underground mines include real-time air quality sensors and ventilation-on-demand (VOD) systems.

Key fact: Powering ventilation systems consumes 25-50% of the total energy requirements of an underground coal mine
