Sigra is proud to announce that Dr. Ian Gray, a globally recognised expert in geomechanics and underground mining, will be presenting at Longwall 2025. His talk, titled:

“Rock Stress Changes and Failure Behaviour Around a Longwall”

will provide invaluable insights into the complex stress changes and rock failure mechanisms that occur around longwall operations.

Why Attend?

Longwall mining presents significant challenges in understanding how rock behaves under shifting stress conditions. Dr. Gray’s presentation will explore:
✅Rock stress measurement – what it tells us
✅The importance of rock properties in compression, shear and tension
✅The changes in stresses around a longwall
✅Weightings
✅Predicting goaf falls

This is an incredible opportunity to engage with one of the world’s foremost engineers, ask questions, and gain expert insights that could impact the future of longwall mining.
