Blo-Up

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.

Blo-Up is a three-component coupled model of rock blasting. A coupled modeling approach was chosen because no single numerical technique was found to adequately describe all the physical phenomena occurring during blasting. The three components are (i) a continuum geomechanics model for the early-time detonation and near-field crushing; (ii) a brittle discrete element model for stress wave propagation, fracturing and burden movement; and (iii) a gas product model for burden acceleration by gas expansion, fracture flow, and atmospheric venting.
