HOISTING TECHNOLOGY with the need to expand production, many mining companies are pushing the limits of their current and planned shaft capacities. Doing so requires taking a systems design approach that holistically integrates equipment into the hoist and material handling process. Recent Stantec designed systems have utilised some of the largest hoisting equipment produced with up to 65 t capacity skips operating on six 56 mm hoist ropes, headframes up to 100 m tall and hoists with more t han 12,000 kW in drive power – all in shaft diameters that have not grown proportionately.” The company adds: “Effective system design and integration includes much more than simply purchasing the latest, largest equipment. To get the best results, designers must ensure the A Stantec winder design for an underground potash operation Cradle to cradle equipment is sufficiently proven for the application and that it fits together as an integrated system. The hoist plant system design and performance requirements are established very early in the design process. Through the detailed design and implementation process, experienced designers apply all available tools with close attention to detail to maintain the integrity and performance of the designed system. Models, and simulations in particular, are often used to mitigate risks and apply Prevention Through Design – also called Safety by Design – especially when equipment and systems are pushing the limits.” ABB in Americas and Europe Exploration, feasibility, due diligence, engineering and operations through to mine closure.

The greenfield mine is an expansion of Mosaic’s established potash mining operations in the area. The K3 mine, located east of the town of Esterhazy, in Saskatchewan, has reached potash at a depth of 3,350 ft. For this project, ABB will supply the production hoist and all related mechanical and electrical systems at the South shaft of the K3 mine. Mechanical equipment for the friction hoist will include ABB’s high power, low speed synchronous motor and ABB’s newest SIL 3 rated Safety Brake System to provide the highest level of safety, security and reliability for hoist operation. At 15,800 kW, this will be the largest mine hoist electrical powertrain in North America. ABB will also supply the hoist control system, other power infrastructure and automation equipment, as well as engineering, turnkey installation and commissioning, and other services. The new hoist is scheduled to be commissioned in 2021.
