Abstract
Coupling effects of the stemming materials for single borehole were studied by AUTODYN analysis and compared to understand the role of different stemming materials on transmitting the pressure from blasthole to the surrounding rocks. Five different material properties, air, sand, water, 10% and 20% gelatin were selected. Authors assumed that high pressure detected in borehole means better fragmentation. Simulations show that these coupling materials lead to different level of pressure in the blasting hole and 20% gelatin turns out to be highest among them. Results show that gelatin can be used as better coupling material than sand or water.
