debris and dust, this process presents hazards that can be eliminated through the application of automation and robotics. ABB, in partnership with Boliden and
LKAB, and explosive suppliers Forcit and Kimit, are developing automated robotic explosive charging technology as a solution engineered to combat this challenge. Designed to remove people from the unprotected area around the rock face during charging sequences, the robotic blasting system automatically scans the face to detect boreholes. The system then calculates how to reach all holes, and how to charge them, before deploying the charges. This ensures that the knowledge and expertise of these operators is retained, while enabling them to complete their critical role with less risk. In tandem, the use of robotics can
result in more consistent charging, as the robot will lay the charges in direct accordance with the programmed plan. Additionally, employing technologies such as machine learning alongside its ability to record all loading results
and provide data insights, means the robotic blasting system will become more efficient over time and ultimately improve the process. Prioritising the well-being of workers
requires addressing more than the physical risks, but also the biological dangers associated with the hazardous environment of mines. Effective ventilation is key to safety. The inhalation of toxic fumes and gases, or dust caused by disturbed rock, can lead to a myriad of health problems. All mines are therefore equipped with the appropriate ventilation systems. However, with the implementation of automated solutions such as the ABB Ventilation Optimiser, processes such as blasting, and ventilation can work together to improve efficiency for greater safety. The next step in mining automation
is to incorporate more effective automation technologies in the planning schedule and production control. This automated layer will connect several daily processes, such as ventilation, dewatering, conveying systems, and in-pit crushers, as well as
mobile machines, to give the operator a wider view of the process and promptly react to disturbances. Safety elements can then be activated as and when needed.
PRIORITISING SAFETY WITHOUT COMPROMISING ON SUSTAINABILITY Initiatives for circular economy within the mining are crucial to the industry’s overall sustainability targets, and robotics and automation technologies are vital components in driving these efforts. Through automated processes, consumption can be optimised and managed more efficiently, from energy to water usage, while also improving waste management. Robotics can also support wider
sustainability efforts. The robotic blasting system not only improves safety but contributes to the increased sustainability of the mining operation. Its precise technology results in more controlled blasts and an increased efficiency in the use of explosive materials, minimising environmental impact on the surrounding area and generating better rock fragmentation. More effective blasting equates to lower energy usage, increasing the efficiency of the downstream process in the value chain.
THE CONNECTED MINE Integration of automation, robotics and digital solutions will continue to revolutionise the mining landscape, offering safety, efficiency, and sustainability advantages. By removing workers from the danger zone whilst retaining invaluable skillsets, improving efficiencies, and integrating modern technologies, the mining industry is opening the doors to the next generation of workers. The automated mine of the future
is not such a distant dream anymore. As the mining industry continues to embrace these technologies, it is poised for continued innovation and evolution to greener, more connected operations. ●
