Assessment of Charge Initiation Techniques Effect on Blast Fragmentation and Environmental Safety: An Application of WipFrag Software

Blast charge initiation procedures have a significant impact on both mining safety and production rates. In this study, the inventory benefit of an electric system was investigated to assess its influence fragmentation blast-induced damages. The WipFrag software used examine size distribution productivity 12 small-scale blasts initiated by nonelectric detonators. All blast rounds were with plain-type NONEL average burden, spacing, stemming length, weight were, respectively, 0.85 m, 1.10 0.66 1.1 kg. results showed that mesh through which 80% fragments passed for smaller than material products from passed. also demonstrated generated ground vibration (PPV) all varied 0.4–1.2 mm/s 80–105 dB, while ranged 0.05–0.2 72–95 dB. As result, technique found produce good fragmentation, higher percentage optimum fragment sizes spec nonelectrically blasts.
