SRK's 45th Anniversary

 
 
SRK undertook a multi-disciplinary design of an integrated hydroelectric power, mine waste rock and tailings storage facility. The design features a 190.5 m  high asphalt core rockfill dam, two diversion dams, a 35.5 m high cofferdam, two diversion tunnels, and hydropower intake and conveyance system linked to a turbine facility, and a side-hill spillway. Designing for this unique setting presented challenges including the remote location, 8 m of rainfall per annum, high seismicity and steep terrain. SRK undertook complex 3D limnological modelling to characterise the behaviour of the waste rock and tailings planned for sub-aqueous disposal into the reservoir.
