Project Work

Itasca works around the globe providing optimized projects for our clients, tailored to their needs, and often dealing with the most complicated non-linear problems in rock mechanics and engineering. Some of our published work can be found here.

Large Open Pit Stability

Since 2005, Itasca has been one of the key contributors in the extensive research project on large open-pit stability, the Large Open Pit (LOP) project, initiated by the CSIRO Division of Exploration & Mining.

One of the central objectives in open pit mining is establishing reliable slopes; slopes that are predictable even in failure, in order to prevent severe consequences. Itasca has been an integral part in the study of the relation between rock mass strength and deformability, and slope failure mechanisms.

Itasca has been working with AngloGold Ashanti in South Africa to understand rock behavior, especially brittle failure mechanisms, inherent in deep gold mines in South Africa. The ultimate goal of this work is to develop a rational methodology for mine design, especially as mining continues deeper. Itasca is doing this by developing a generic mechanical model for rock behavior around advancing stopes in deep gold mines that can reproduce the induced fracture patterns.

Since 2001, Itasca has been a member of the Hybrid Stress Blast Model (HSBM) project with the goal of developing a numerical model of the rock blasting process. The software created by Itasca, called Blo-Up, uses a unique combination of continuous and discontinuous numerical methods to represent the key processes occurring during blasting.
