BESTECH executed the complete multi-disciplinary detailed engineering design for two new surface fans for Glencore (formerly Xstrata Nickel) at the Fraser Mine site. Each fan is 2250 hp and generates 1.3 million cubic-feet per minute of fresh air for the underground operations. The fresh air intake is needed to sustain the underground mining operations at Glencore’s Fraser Mine and the system pushes additional fresh air into the neighboring Coleman Mine, owned by Vale Canada Limited.

The scope of work consisted of all the electrical, mechanical, civil, structural, and automation engineering components for the design of the two new surface ventilation fans, including:

  • Detailed engineering, tender document preparation, bid review, construction assistance, construction inspections, commissioning lead, PLC program demonstration, operator training, and the manual for the operation, maintenance and surveillance of the system
  • Electrical SOW for the relocation of various assets within an existing electrical building to allow for the addition of two new VFDs and a new switchgear line up
  • Heat study of the electrical building with existing and additional assets
  • HVAC upgrades required for the electrical building
  • Bowtie deposit ventilation infrastructure including dual parallel fans, regulating high pressure steel sectional doors (used as regulators), instrument clusters, electrical room, power distribution and automation
  • 3,400L ventilation infrastructure including air lock doors and under_x0002_ground stench deployment
  • Demolition scope for the old surface fans, including electrical system, control interlocks, PLC programming, and validating and engineering the structural integrity of the remaining infrastructure
