Аннотация

This paper investigates the effect of detonator placement within a borehole charge on rock fragmentation during blasting operations in open-pit mining. Different detonator positioning options, including placement at the bottom of the charge and at its central section, are analyzed with respect to stress distribution and explosive energy utilization. Theoretical analysis and field test results demonstrate that positioning the detonator at the center of the charge provides a more uniform distribution of blast energy, reduces the proportion of oversized rock fragments, and improves overall fragmentation efficiency. The findings indicate that optimizing detonator placement can significantly enhance blasting performance and increase the productivity of mining operations.
