Using numerical modelling for simulating manufacturing processes and predicting final properties is more or less mandatory in many industries. However, it is barely used within the rock drilling market despite being a powerful and cost-efficient method.
This is why GEOFIT will introduce a novel particle-based finite element method for modelling the drilling and excavation process. With this new approach, we aim to assist operators in choosing optimum drilling parameters and tools to reduce wear These simualtions will then be validated by comparing the outcome with the data from some of the pilots.
They key strength behind these simulations is their potential to simulate the rock fragmentation processes. The rock material will be mechanically characterized and finally the numerical approach will be validated by comparing the outcome with the data from some of the pilots.
In this video below you can see some of the numerical simulations developed up to date by the group at the Division of Mechanics of Solid Materials of Lulea University of Technology (LTU) for the GEOFIT project.
