Modern Quarrying Q3 2021

tries is that increasing productivity and improving safety are two sides of the same coin. A safer operation is, in fact, a more productive one. A range of risk mitigation technologies from Trysome is set to profoundly impact safety in the quarrying industry. One of the key issues in the quarrying industry at the moment is the promulgation of the mandatory use of collision avoidance systems and proximity detection systems by surface mines and quarries on trackless mobile machines, based on their own risk assessments. Johan Momberg, key account manager at Trysome, says surface mines and quarries are under pressure to comply with the Department of Mineral Resources and Energy’s regulations to keep their staff and assets safe. However, he says the regulations are not just about the implementation of collision avoidance technologies but also about performing risk assessments to determine if an operation needs to adopt these technologies. Trysome, based on its experience in this field, can help operations with their initial risk assessment and, ultimately, collision avoidance technologies if need be. “The biggest challenge for quarries with regards to collision avoidance systems is that they don’t have the capital like their bigger mine counterparts to implement these systems, which generally cost millions of rands,” says Momberg. “Fortunately, the legislation provides for operations to start with risk assessments to determine if they need to implement these systems. We work closely with our customers to help them do their risk assessments, and where we cannot mitigate risk with our site administration protocols, we can provide fitting solutions to meet the specific needs of the customer.” One of the key technologies from Trysome is the HxGN MineProtect Vehicle Intervention System (VIS). It is said to be the first system to automatically recognise hazardous conditions and take control of a vehicle when an operator fails to do so. If an imminent collision is detected, VIS cuts vehicle propulsion, applies the retarder, or activates the service brakes. Integrated with HxGN MineProtect

incoming and outgoing materials, and maximise the load capacity of haul trucks without overloading.” The Walz Scanner System has been designed to interface directly with mine-site data infrastructure systems. The interface allows for the data to be delivered to key mine-site personnel, in real-time, for monitoring and analysis. Passing beneath a laser, each haul truck bucket is scanned and referenced by advanced algorithms and sophisticated software, resulting in an accurate volume estimation generated by 2D load images. Using this method, load volumes can be calculated to within a proven and tested ± 99%.
