Numerical investigation on impacts of blast-hole deviation on fragmentation
The accurate drilling of holes is essential for a good blast performance. However, the blast-hole deviation is frequently experienced in mine as the bit advance deep into the rock mass.
The objectives of the project are to develop a procedure to evaluate the impact of blast-hole deviation on blast performance based on cutting edge numerical modelling and develop a modelling-based assessment procedure for given blast-hole deviation patterns. The goal is to provide a better understanding of the effect of blast-hole deviation on fragmentation and develop a numerical tool to evaluate the effect.
Project funding organisation: The work is conducted with-in the Strategic innovation program Swedish Mining Innovation (SMI), a joint effort of Vinnova, Formas and Swedish Energy Agency.
