In a recent update on its electrification journey, potash miner Nutrien points out that for more than 60 years, electric-powered machinery has been used in its underground mines. Borers were some of the first electrically driven machines used in its mining operations, and now, approximately 75% of Nutrien’s underground horsepower is electric.
The company adds that it is continuously seeking opportunities to expand its electric vehicle fleet. Most recently, it introduced battery electric vehicles (BEVs), which are powered by rechargeable lithium-ion batteries and electric motors.
Looking at actual units, Nutrien’s fleet at its six major Saskatchewan mines – Lanigan, Cory, Vanscoy, Allan, Patience Lake and Rocanville – includes electrically powered borer miners, haulage systems and continuous miners from Prairie Machine, Komatsu (Joy) and Sandvik, as well as Rokion battery personnel carriers.
“In 2011, the first BEV was built and trialled underground at our Cory potash mine,” says Joel Thon, Senior Electrical Engineer. “The development of the first BEV at Cory is what really spurred innovation in the use of BEVs in Nutrien’s mines. Many of our sites are extremely interested in increasing their electric vehicle fleet in the coming years, and we’re looking into adding more personnel carriers and larger options of BEVs like scoops, haulers, bolters, skid steers and forklifts.”
Nutrien points out that replacing diesel-powered vehicles with BEVs in its mines has air quality and safety benefits. BEVs produce zero tailpipe greenhouse gas emissions. This reduces direct harmful pollutants like nitrogen oxides and particulate matter, which improves local air quality and reduces respiratory health risks for mine workers. Additionally, BEVs are much quieter than diesel engines and the reduction of noise pollution creates a more comfortable work environment. BEVs also do not carry the risk of diesel spills and have no associated flammable fuel storage.
Since 2013, Thon has been supporting the Electrical Integrity program within Nutrien’s potash business unit. This includes developing and leading electrical safety, maintenance and training programs, overseeing its electric vehicle policy, and consulting on new initiatives. He is currently advancing an electric vehicle specification document, developing a feasibility study for a full underground electric fleet, and working with the Canadian Standards Association on a national standard for electrically driven machines in underground mines.
“My favorite part of my job is being involved in most of the electrical projects across the potash business unit,” says Thon. “Being part of innovative projects is an amazing experience, and I’m proud to be working in Saskatchewan for a company that has a deep-rooted history with the province and its people.”
