Sigra Presents at EUROCK 2018

Sigra Visits St. Petersburg for the Eurock 2018 Symposium and Presents Keynote Address and Day Course in Rock Mechanics

Sigra’s Managing Director, Dr Ian Gray, recently attended the International Society of Rock Mechanics symposium, Eurock 2018, in St. Petersburg, Russia. This is the main European rock mechanics conference for the year. The themes of the symposium were Geomechanics and Geodynamics of Rock Masses.

Sigra Eurock 2018The keynote address, presented by Dr Gray, covered the Anisotropic and Nonlinear Properties of Rock Including Fluid Under Pressure. The work follows a theme of experimental work and analysis by Sigra into determining real rock behaviour. This is of considerable interest to all practising designers in rock, as well as a number of researchers who have trodden some similar ground.

In addition Dr Gray presented a day course on Rock Mechanics from Broad View – Civil, Mining and Petroleum Engineering. The course material is available for download in Russian and English from —-
Sigra is grateful for the opportunity to continue to be recognised on such an international level and would like to thank our translators, Nadezda Nikitina assisted by Yulia Shelukhina. We also wish thank those who approached Dr. Gray to share thoughts, professional opinions and to work cooperatively with us.

In 1990 he became Principal Engineer, Mining Research with the Safety In Mines Testing and Resarch Station of the Department of Resource Industries of the Queensland Government. In this role he worked on frictional ignitions, mine explosions, windblasts, gas drainage and directional drilling including the first surface to in-seam operation in the country in 1991. In 1994 he started Sigra as a one man business. Since then the company has grown under his guidance to span mining, gas, civil, geotechnical work and a number of mechanical and electronic product developments.
