The Future is Now: Normet’s Virtual Reality Sprayed Concrete Training Simulator

Training personnel to use machinery such shotcrete sprayers can be tricky. Ultimately, we need to find a way to provide efficient, realistic training without putting people in danger or risking damage to expensive machinery. Normet offers the solutions with its virtual reality sprayed concrete training. This advanced software does more than mimic the application, it calculates everything that comes through the nozzle, with real adjustable properties and behaviour of sprayed concrete mix. This whitepaper explains how this impressive technology works and how you can utilise it to get your workers ready for the field.

The current increase in the number of mines choosing to blast rock with emulsion explosives has been one such step along this journey.

For the majority of the twentieth century, nitro-glycerine (NG) and ammonium nitrate fuel oil (ANFO) explosives were the chosen chemical compounds for blasting processes. In the following century, they were almost entirely replaced by modern alternatives such as pumpable emulsions.

The benefits of emulsions are unrivalled. They have made blasting a far safer practice due to their status as a 5.1 oxidiser until sensitised in the drill-hole and charged, making them safe to transport and handle underground.

But developments in the mining industry have not stopped there. This summer, Normet made history by being the first to pioneer a groundbreaking battery-based explosives charging process.

Battery-based charging for emulsion explosives

The new technology was tested and demonstrated underground at First Quantum Minerals’ Pyhäsalmi mine in Finland this June.

Underground mining and tunnelling company Normet deployed the Charmec MC 605 VE SD machine for the demonstration. The Charmec MC 605 VE SD leverages the company’s well-known Charmec charging technology, which has proven highly efficient for miners operating in even the toughest underground conditions.

The battery-based technology was integrated into the company’s SmartDrive battery-electric vehicle (BEV) range. The BEV range represents yet another positive development in the modern-day mining industry, as more and more companies have turned away from diesel vehicles towards those with zero-emissions to achieve higher productivity, safety and sustainability.

To be powered, charging equipment is traditionally hooked up to the mine’s electric grid. However, Normet’s latest battery-based explosives charging development has shown that there is a safer, easier and more efficient way to charge emulsions without relying on the grid.

Charmec MC 605 VE SD presents the future of explosives charging in underground mines. Integrated with the new battery-based emulsions charging technology, the SmartDrive electric vehicle offers Normet’s customers the highest value in terms of health and safety, ergonomics and productivity, with zero local emissions.

It comes with a full range of accessories that can be added on to fulfil a variety of customer needs.

This new battery-based charging technology complements Normet’s range of underground charging machines. Each piece of equipment has been designed and developed with the ever-pressing issue of safety in mind, and the Charmec MC 605 VE SD represents the latest step Normet has taken towards meeting the industry’s common goal of safety while satisfying even the most demanding of customer needs all over the world.
