July of 2015, Underground Bin refurbishment
In this project Fortis leveled the bin structure and replaced the suspension cables that supported the bin. The new cables were equipped with load cells for uniform and controlled tensioning. The load cells will allow for close monitoring of the loading on the cables. Fortis built a cat walk to enable the maintenance personnel to check the cables and the load cells. The maintenance personnel can visually inspect each cable and load cell and make adjustments as required.

January 2013, #2 Shaft, 13.8kV Feeder and Associated Cables Installation
The project biggest challenge was the high traffic demands of the shaft to move Mosaic’s labour force in and out of the mine. Together with Mosaic, Fortis’ highly skilled personnel evaluated alternate methods to complete the scope of work in a safe and timely manner while allowing this movement to occur as to not disrupt production. Fortis compiled a methodology and timeline that met these demands and resulted in the project being completed according to schedule and incident free.

Summer/Fall 2013, Blocking Brackets and Shaft Guide Replacement
The scope of work included the supply of the blocking brackets and removal and replacement of the shaft guides. This project was a three-phase project with SanGold. Phase 1 was completed by our manufacturing department where they fabricated all the blocking bracket and aluminum head cover. Phase 2 involved sending our mining work force to install the shaft blocking brackets. In October 2013, our crew returned to complete Phase 3 of the project: the installation of the shaft guides. Installation of these guides resulted in an increased skipping capacity.

Fortis was contracted to install six 25kV Feeder Cables in the Service Shaft. Fortis successfully completed the installation of three cables in 2011 and the remaining three in July 2012. Fortis utilizes a cross head with integrated camera to guide the cable down the shaft to the lower drift level at the bottom of the shaft. The cross head is assembled in the shaft on top of the skip or cage. Camera provides live video of the cable being lowered down the shaft. Fortis is using a load cell to monitor the weight at the sheave.

2010
Fortis completed shaft remediation on the concrete liner in #2 Shaft. Over time water began eroding the ground behind the concrete liner. This erosion then put pressure on the liner and began to push it out into the shaft. Fortis installed mine grid mesh and steel strapping to temporarily secure the liner until a long term plan is developed to repair the concrete liner.
