Job Description
Technical Expert, Underground Expansion Ventilation-1105118
Description
The incumbent in this Technical Expert role will work with the national staff to plan, implement, control and maintain the technical and engineering aspects of the ventilation system in the assigned underground mine operations area by in-depth analysis and concepts. Support the Underground Mine and mentor the national staff to enhance and develop skills and knowledge.
This position (UG Exp. Vent) reports to the Superintendent for Big Gossan Mine Ventilation. The Big Gossan Mine is a transverse open-stope mine with delayed past fill that is currently ramping up to the designed production capacity of 7,000 tonnes per day. This mine ventilated by two 3.5 meter diameter, 1,600 kW Mixed Flow Fans. Fresh air enters the mine through several levels over the ±600 meter vertical extent, flowing downwards through ramp and fresh air raise, after exhausting from a level the ventilation returns flows upwards to the main fans, which are situated underground, before discharge through dedicated exhaust drifts. A Ventilation-on-Demand test platform is being developed in this mine to guide and assist the implementation of similar, larger scale systems at the block cave mines in the same mining district.
Additional responsibilities:
1. Observe the implementation of safety, environmental, and job specific standards and procedures within work area to minimize accidents and damage to equipment while ensuring that tasks are completed in an effective and timely manner.

5. Develop medium and long-term plans that cover the engineering calculations for ventilation shafts, drifts, number of fans, doors, and other related necessities by analyzing the on-going underground mine development to provide effective, engineered ventilation solutions.
6. Develop and calibrate mine ventilation models using dedicated software such as the VnetPC and ClimSIM. Apply these models to determine fan duties and size ventilation control devices to match the airflow requirements. Compare the simulator results against the field data to ensure reliable predictions.
7. Coordinate with Management on the purchase of new equipment by providing the necessary information and ensure that the purchase is made in an efficient, effective and timely manner.
