Coffey’s experience with large scale mining operations contributed to a positive outcome of the feasibility study.  

Situation

This project’s mine pit has a strike length of approximately 6km, a width of 1.6km and a depth of in excess of 600m, resulting in total material movement of up to 300Mtpa.

With a mine production fleet of approximately 140 pieces of equipment, including drills, shovels, trucks and FELs, there was a high probability of traffic congestion becoming an issue on site.

Solution

Our role was to assess whether the mine production schedule could accommodate such a large quantity of equipment.

A typical production year was selected for detailed scheduling in monthly increments. The schedule was assessed for potential access restrictions, the requirement of temporary ramp systems. Also the impact of mine equipment working on multiple cutbacks with potential of working above and below active mining faces, and actual truck requirements in relation to the number of working faces available, and designed ramp systems.

Result

The assessment highlighted minor operational issues, but also provided Iron Road with the confidence that the proposed mine production schedule would deliver a practical solution.
