Mining companies and OEM suppliers alike strive to develop responsible mining practices, with safe and cost-effective production. One major step in this quest is to reduce diesel-powered equipment underground, which has a positive impact on environment, health and safety and also brings a big reduction in costs of ventilation. In particular, it reduced miners exposure to diesel particulate matter (DPM) a significant health risk.Goldcorp, a leading gold producer with production throughout the Americas, is working with Sandvik Mining and Rock Technology to make its Borden Lake project one of the world’s first all-electric mine.Borden Lake, located in the Canadian province of Ontario, is part of Goldcorp’s pipeline of organic growth projects. In 2015 Goldcorp announced indicated resources of 1.6 Moz of gold at Borden Lake. As part of the development process, Goldcorp committed to making Borden Lake the world’s first all-electric mine, in order to ensure a higher standard of health and safety for employees and reduce both environmental impact and capital costs. Development at Borden Lake is scheduled to begin in early 2017. Goldcorp has selected Sandvik Mining to provide a complete electric solution, including development equipment for the Borden Lake mine.“We can provide a full solution for development equipment for the mine because of our breadth of offering,” says Dale Rakochy, Business Line Manager, Underground Equipment. “It’s a fully integrated battery technology where you don’t have to remove, handle or swap batteries underground, providing improved safety for operators and maintenance crews.”One of the equipment models already ordered for this project is Sandvik DD422iE, on display at the Sandvik booth at MINExpo. By using electric energy from an onboard battery during tramming, Sandvik DD422iE produces zero emissions while manoeuvring between headings. This improves health and safety for miners working underground. Less diesel usage in a mine thanks to diesel-free drilling can ease ventilation requirements, while also reducing associated diesel logistics and maintenance expenses.Using the mine’s existing electric infrastructure, the Sandvik driveline technology enables the battery to recharge during the drilling cycle. The battery will even recharge while Sandvik DD422iE is tramming downhill, using energy generated by the braking system. The long-lasting pack will power the drill efficiently throughout its lifetime.Goldcorp has a long term vision to develop the Borden Lake mine to be one of the most environmentally friendly mines in the world. It has selected Sandvik Mining to help develop technologies and equipment to meet this goal. A collaborative effort between Sandvik and Goldcorp will occur in the first years of the mine development to help ensure optimal solutions to achieving a truly green mine.“This is truly a mutually beneficial relationship between Sandvik and Goldcorp where both companies have put a plan together to advance the technology needed for the project over the next three years,” Rakochy says.
