Autonomous haulage systems – the business case
A cost-benefit analysis of an autonomous haulage system that demonstrates the potential for productivity improvements The mining industry is constantly seeking ways to lower costs and increase efficiency, particularly given that product differentiation activities are limited due to general commodity homogeneity. Heavy industries, including manufacturing and transport, have adopted various technologies such as robotics-based systems to increase efficiency and lower costs. The mining Read More

Designs for highwall safety bunds in open cut coal mines
Correctly designed and cost-effective highwall bunds are essential for safety in large open cut coal mines Highwall and low wall stability are essential during open cut mining. Geotechnical investigations are required to quantify the mass and substance properties of soils and rocks within the mining horizons. The required minimum safety factor for open cut batters is 1.2. The effect of highwall mining and augering needs to be considered for long-term highwall performance. Temporary Read More

Telerobotics for hang-up assessment and removal
Penguin/Codelco team up to use robotics to solve an age-old problem in cave mining – hang-up assessment and removal The removal of rock blockages in mining operations has long been a risky undertaking, especially in high overhead conditions. In fact, the assessment of where to place charges has been difficult due to the lack of visibility and safe access to the area. Thus, the traditional practice of wedging long poles with explosives on them, keeping the operator in as safe a location Read More

Flash flotation equipment design
Flash flotation is a mature application of flotation technology to recover fast-floating liberated particles from within the grinding circuit before they can be ground further Flash flotation is the rapid flotation of mineral particles to produce a suitable concentrate. Normally, the feed to a flash flotation cell is the cyclone underflow stream. The aim when treating cyclone underflow is to recover liberated fast-floating mineral particles before they present back to the grinding mill Read More
