Nov 2016 - Present
Tasked with a dewatering target to get the ex-mine flowrate to 450 l/s of 80 degree Celsius (176 degree Fahrenheit) water. Design and manage construction of underground dewatering project to safely de-water below production levels to extend mine life. This includes consolidating and improving current capital pump station infrastructure to maximize ex-mine water and to add contingency to avoid flood events. Design of deep bore installations and reticulation pathways through return air ways to better manage heat transfer and workforce exposure to hot water. Simplify and automate system to better manage power outages and pump failures. Redesign lower decline to manage hot water flows and mining fronts with active dewatering cuddies and satelite pumping systems.
