FATIGUE MONITORING & COLLISION AVOIDANCE Satisfaction in safety Paul Moore reviews some key developments in fatigue monitoring and collision avoidance systems in mining, including some big rollouts at major operations  atigue monitoring, especially of haul truck drivers; and Collision Avoidance Systems (CAS) are now major focus areas for most mining houses, with trials and testing now having been replaced by full rollouts and meaningful results in terms of safety. Initial operator hesitation in terms of feeling they are being watched in relation to the fatigue systems, has largely been replaced by a feeling of reassurance that someone is watching their back in case they do succumb to tiredness in what the industry calls a microsleep. CAS systems are getting ever more advanced and being integrated to a greater degree with other systems such as those for fleet management. In July 2017, Guardvant, one of the industry leaders in real-time operator fatigue detection, announced it had been selected by Glencore Australia for its Ravensworth open cut coal operation. Guardvant’s OpGuard system will be installed on a mixture of 54 Caterpillar 797 and 789 trucks. Ravensworth’s Mine Manager, Murray Gregson explained: “We selected Guardvant after an extensive year long trial of their system. We wanted a reliable non-intrusive system that assisted us in detecting and supporting our operator’s fatigue management. We found the Guardvant OpGuard system surpassed these requirements and added additional benefits of mobile phone detection and a forward-facing camera.” Guardvant Australia’s Managing Director, Sean Perry says, “it’s been a very thorough trial of our solutions, with significant developments and improvements along the way at the request of the customer. Putting our product through Glencore’s Failure Mode Engineering Analysis F 40 International Mining | JANUARY 2018 (FMEA) and Risk Analysis process was a stepping stone to ensuring our product met Glencore’s high standards.” Ryan Hawes, VP Business Development at Guardvant told IM that the company has quite a few trials and installations ongoing going, however, due to confidentiality agreements they can’t yet be made public. In addition to this, he said the company has new solutions that will be coming out in 2018. OpGuard is a non-intrusive fatigue and distraction solution that continuously monitors operators to proactively prevent accidents. OpGuard’s infrared camera continuously monitors the operator for eyelid closure, facial and head movements, and other unsafe behaviour (mobile phone use, reading, etc) while the vehicle is in motion. SmartCap moving ahead In May 2017, SmartCap Technologies announced its new collaboration with Newtrax Technologies. These two industry-leading safety solution providers are adapting Life by SmartCap, already a world-first solution, into one that will suit underground mining conditions. The new initiative will bring many benefits to both operators and supervisors alike. Life provides real-time alerts to prevent microsleeps before they happen, empowering users to be their own fatigue manager. Supervisors will have real-time data access so they can make fact-based decisions that keep their workforce safe. Back on surface, at the BHP-operated Escondida copper mine, a recent successful trial of SmartCap Life has seen the system there To date there are 1,757 DSS units being used in mining operations and supported by Caterpillar adapted to integrate the EEG brainwave sensor into the webbing of hard hats rather than the original baseball caps. BHP's Chief Technology Officer, Diane Jurgens, told Sydney Morning Herald: “It’s in 150 plus trucks, so it's not inexpensive, but in terms of safety it's really effective. So we are going to be rolling it out across our other operations as well. The technology right now is only used in Chile, but it's applicable across all of our operations,” she said. SmartCap Life is non-invasive and uses EEG (brainwaves) technology to monitor operator fatigue. Life measures an operator’s ability to resist sleep and provides alerts as they progress to a place of risk. Daniel Bongers, Chief Technology Officer at SmartCap told IM: “We’re proud to be working with BHP to help their operators come home safe every day. With deployments at multiple BHP sites and its contractors, we’re excited to be part of BHPs efforts to integrate its operations.” He added that in addition to the deployment at Escondida, the system is already fully deployed at another BHP site. In terms of wider deployment he states: “As an industry-proven, repeatedly validated technology, we now have mining deployments in the following countries: Australia, USA, Canada, Chile, Peru, Mexico, South Africa, India, Mongolia and Madagascar.” The company is seeing a trend of sites replacing camera-based technologies with SmartCap. “Our clients consider falling asleep at the wheel an incident, and camera-based technologies are really in the business of counting these incidents. As an early warning solution, SmartCap empowers individuals and businesses to prevent the incident by intervening well prior to dangerous sleep events. Our new product, Life by SmartCap, is a truly ‘anywhere, anytime’ solution that allows real-tim
