Player spent seven years from 2003 undertaking his PhD (Dynamic Testing of Rock Reinforcement Systems) then continuing as a Senior Research Fellow to undertake further data analysis and continue to develop the WASM Dynamic Testing Facility and associated equipment for determining the performance of reinforcement and support systems. During this time he has also undertaken consulting work to open-cut and underground mines in Western Australia.

Player spent seven years from 1996 at Big Bell Mine:
  • Two years as Drill and Blast Engineer for the sublevel caving operations where he achieved the implementation of a data tracking and control process, standardisation of blasting practices, reduction in drill and blast costs and minimisation of bridging in the cave.
  • Five years as Geotechnical Engineer (plus often undertaking the drill and blast role), incorporating a two year period of high mine seismicity, supervision of contractors for ground support installation, designed and installed the micro-seismic system, implemented change to the mining operations (cave geometry, extraction rate and development location, ground support requirements) to substantially reduce damaging mine seismicity.
