Principal Rock Mechanics Engineer - Michael Di Giovinazzo

Michael Di Giovinazzo is a rock mechanics engineer with over 14 years’ experience in hard rock underground and open cut mining. He is a Member of the AusIMM and holds a GCertEng in Mining Geomechanics (with graduation to MEng expected in 2015) as well as BSc in Applied Geology.

Michael’s rock mechanics engineering experience spans over 11 years’ across underground and surface mining operations, operational geotechnical team leading, and feasibility studies. He joined SRK in September 2013 from Australia where he was most recently Principal Geotechnical Engineer for Newcrest Mining at the Telfer Gold Operation including deep SLC, two open cuts, cave-pit interaction, and open stoping. Prior to this, he held Senior level roles covering geotechnical planning and guidance of numerous brownfields underground and open cut projects.

Specialisations include operations support, geotechnical risk management, rock mass classification, underground mine design (Sub-level Cave; Room & Pillar; Open Stoping), slope design and optimisation, underground and open pit interaction, static and dynamic ground support design, ground monitoring design and installation, ground monitoring data interpretation, seismic hazard management, and numerical modelling in 2D and elastic 3D.
