2038 Figure 5 – Results of fragmentation simulated with AI support Two industrial-scale trials were carried out using blast patterns designed for 7 7/8”, yielding X80 values of 22.4 cm and 28.2 cm. These results are very close to the optimum, and there is still potential to reduce the powder factor and the explosive charge used. The methodology used to measure fragmentation was based on approximately 400 elevated images taken in the field after blasting and during mining using PortaMetrics™ Gen 2. With blast patterns designed for 9”, 15 industrial-scale blasting trials were carried out (Fig. 6), and the results are presented in Table 5. Figure 6 – Drilling completed for the blasting test
