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

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.”

24 International Mining | AUGUST 2017
ABB recently announced that it will design,
deliver, install and commission the friction hoist
with all related mechanical and electrical systems
for Mosaic’s new K3 potash mine in
Saskatchewan, Canada. 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.
