AUTOMATION IM spoke to Ulla Korsman-Kopra, Global Business Manager, Automation and Information Management, at Epiroc Q In surface mining the focus is now retrofit autonomy, is this trend being repeated underground? A To some extent. Retrofitting advanced OEM technology will certainly increase safety and productivity and can be the first step in increasing autonomous capability. Third party retrofit solutions can also provide value in basic control and monitoring; however they don’t have the capability to utilise the full functionality of the later generations of underground machines. For example, you can certainly retrofit a modern production drill rig and operate it from a more safe location; however its functionality won’t include the onboard execution management system. It will no longer have the capability to autonomously drill a complete fan, changing drill bits as required. And it certainly won’t continue to operate over shift changes. The appeal of retrofit solutions is its cost and ease of implementation. For some mining operations, it might indeed act as a first step of a technology roadmap. Q Is Epiroc set up to respond to this trend and is this an area of the market you are exploring with ASI? A At this stage, Epiroc’s partnership with ASI is focused on optimising surface operations. For underground operations, retrofit solutions simply won’t provide the step-change in productivity that our customers are expecting from us. Epiroc’s ambition is on leading the development of fully autonomous machines that precisely execute production plans. Q Why have more underground mines not gone fully autonomous by now, as predictions 10-15 years ago would have expected? A Often these estimates only consider the R&D and engineering effort from the technology perspective. They don’t consider the collaboration agreement to validate and improve underground hard rock mining vehicle automation technology. The initial focus of the collaborative effort is Command for underground, the Cat ® system for semi- autonomous and remote operation of underground loaders. Command for underground is a technology within Cat MineStar™. Newmont is the largest user of Cat underground vehicle automation technology in the western hemisphere. The company currently operates underground loaders using Command for loading in its Carlin gold mines located in northern Nevada. The collaboration agreement leverages and builds on this 28 International Mining | APRIL 2019 interdependent work and associated timeframes of working with clients in way that enables all research to be tested and verified in real world operations. There are significant considerations in terms of new operating models, workforce impacts, change management, commercials and liabilities with respect to accountabilities and new regulations for autonomous mines. Further, interoperability standards for automated information exchange are required to enable integration between all mining systems from geological modelling, mine design, mine planning and scheduling, material tracking, fleet management and process control to make this possible. A lot of critical work has been done from a standards perspective (ISO 23725, OPAF, ISA-95, GMG) but this is yet to find its way into mining systems on scale. This is likely to happen in the next 2 to 3 years, which will make possible to have these automated mine factories as you describe and Epiroc’s strategy is to be at the forefront of this work. Q That said with the market picking up and with many companies now having had some experience at least with advanced tele-remote or at least “automation lite” that some are now ready again to look at automating all or at least a significant part of their fleets? A There is certainly an increased interest. The number of ‘innovator’ companies is growing and we are seeing more actively partnering with OEMs and technology vendors to develop autonomous solutions for specific operational challenges. It’s exciting that this now includes multiple equipment classes working together autonomously. Epiroc and its customers are looking to drive efficiencies by equipment automation, as well as leveraging information to improve processes and increase the actual effectiveness of the equipment. experience to take underground vehicle automation to the next level of performance. “Automating underground loaders enables machine operators to work safely and efficiently from a control room on the surface,” said Graden Colby, Underground Operations Manager, Leeville mine. “In addition to enhancing safety, the semi- autonomous system increases loader utilisation, improves productivity and allows one operator to control two or more machines.” The collaboration agreement seeks to improve existing technology and accelerate validation and deployment of new features. Newmont, Caterpillar and Cashman share objectives and align to ensure Command technology delivers Q Are there any flagship underground automation sites from Epiroc where you have been able to gather significant data proving the safety and productivity advantages that you can share publicly? A Epiroc has several such projects currently in development, which will provide world-first autonomous solutions. We will also increase customer value with better production information and reporting production actuals against what was scheduled. Over the next 12 to 18 months, Epiroc will be publishing details as to the innovations, case studies and realised customer value. Q Do you think today’s market has a better understanding of automation benefits and maybe more importantly, how to integrate automation into their existing operations with the right approach to tying in automation with their mine planning and mine development? A The market’s understanding of the value of equipment automation has certainly advanced. Automation solutions are in response to specific customer problems and the miners have been actively involved in the development. This includes innovation in ways of working to allow autonomous equipment operation to safely co-exist with people and other equipment. Epiroc is firmly in the camp that believes that the ‘future mine’ cannot be achieved without designing open systems, processes and information exchange to work together to achieve operational end-to-end objectives. Fortunately, most of the major miners are in agreement. Mining companies that wish to select ‘best of breed’ equipment and technology and have ‘plug n play’ integration would do well to ensure its OEMs and technology vendors genuinely share their vision of interoperability and not just pay it lip service. the desired benefits now and meets expectations for the future. The agreement also provides for sharing information to help guide strategic and tactical decision-making related to automation. The agreement also creates a basis for rapid replication across Newmont’s business. “Through Caterpillar’s global business model and dealer network, our Command for underground operating model can be deployed relatively easily at other Newmont mines and generate additional value from the use of common and consistent operating technology,” said Mike Wundenberg, Newmont’s Vice President of Operational Technology and Innovation.
