The rock drilling and loading processes includes several physical phenomena. For rock drilling: contact between drill bit and rock and interactions between drill fluid, drill equipment and rock cuttings and for loading: the contact between rock and loading equipment. The vision for a future full-scale innovation project is to develop a numerical tool for optimisation of drilling and loading performance to save energy and minimise wear on mining equipment. The prestudy will give the foundation for a full-scale project by showing the strength of numerical models. The main scientific objective of the proposed project is to build physically realistic numerical models for drilling and loading of rock material. The aim is to improve the understanding of the internal workings of rock drilling and loading. Results from the project will facilitate understanding of the physical and mechanical behaviour of rock-fluid-structure interactions during drilling and rock-structure interaction during loading. This is an essential step for future optimisation of rock drilling and loading in mining. Furthermore, the results from simulations will be used to understand the complex Multiphysics of rock drilling and predict the wear on drilling and loading equipment. For validation of the computer models experimental in-field measurements will be performed at the Boliden open pit mine Aitik.
