This tutorial will show how to use the Plot Item Cutting Tool in FLAC3D 7. Creating cut plans is useful for seeing inside 3D model plots. FLAC3D cutting planes include a single-surface plane, a double-surface wedge, and a three-surface octant.
As part of the Hybrid Stress Blast Model (HSBM) project, Itasca has developed software to model the rock blasting process.
The McArthur River mine in northern Saskatchewan is the largest single producer of uranium in the world.
This work presents a hybrid modeling approach to efficiently estimate and optimize rock movement during blasting. A small-scale continuum model simulates early-stage, near-field blasting physics and generates synthetic data to train a machine learning (ML) model. Key parameters such as expanded hole diameter, burden velocity, and gas pressure are obtained through the ML model, which then inform a discontinuum model to predict far-field muckpile formation. The approach captures essential blast physics while significantly accelerating blast design optimization.
