EAGCG is an informal grouping of engineers and geologists with an interest in the operational aspects of ground control in coal and metal mines.

Meetings are open to anyone with the same interest – the aim of the group is to facilitate knowledge transfer to the mining face.

Recent meetings, organised through AUSIMM, have tended to attract more metal miners but the organising committee said coal miners were more than welcome.

With this in mind, the next meeting is to be held in Wollongong on “Stress Measurement, Monitoring and Modelling Techniques and their Design Applications".

Some Australian leaders in the field will present keynote papers, and will be supported by presentations from minesites.

Keynote presentations will include:

  • Richard Hillis, professor and head of the Australian School of Petroleum, University of Adelaide – “The World Stress Map”;
  • Max Lee, principal geotechnical engineer at AMC Consultants – “Stress Measurements – Why, So What, Now What?”;
  • Jim Enever – “A Life in Stress”;
  • Phil Dight, senior principal, Coffey Mining – “Stress

    Around Mineralised Systems”;

  • Winton Gale, managing director, Strata Control Technology – “Stress Effects in Coal Mines and Design Approaches”;
  • Peter Mikula, director of Mikula Geotechnics – “Stressful Mining at Mt Charlotte”; and
  • Peter Malin, professor, Institute of Earth Science & Engineering, University of Auckland – “The Big Boom in Basel, or How Induced Earthquakes (nearly) Sank a Major EU Industry; Is OZ Next?”
