MINERÍA la mejor puerta de acceso al sector minero EDICIÓN 583 / ABRIL 2026 24 This system was further enhanced through the integration of blast design software for drill patterns and charging schemes, enabling pre-blast simulations and precise adjustment of operational parameters. As a result, ore fragmentation was optimized and the P80 value, i.e., the average size of fragmented material, was significantly reduced. The transition to the new system was not without challenges, particularly the need for intensive training and a profound change in operational culture. Workers shifted from manual ignition procedures, personnel withdrawal, and sentry positioning to having the entire blasting protocol managed directly from a central station, significantly strengthening operational discipline. As a result, direct personnel exposure was reduced from three hours per day to just thirty minutes, representing an 85% reduction in operational risks. Operational and economic results were outstanding. Operational discipline improved, with protocol compliance increasing from 75% to 98%. Blasting time was reduced from 60 to 15 minutes, enabling an increase in production from 5,900 to 6,150 tonnes per day, representing a 5% improvement. Effective long-hole drilling hours also increased from 6.2 to 6.8 hours, and drilling equipment productivity improved from 2 to 3 faces drilled per shift. These improvements resulted in significant cost savings, including a 12% reduction in explosive consumption, equivalent to approximately US$ 250,000, and an increase of US$ 6 million in annual revenue due to higher production. The reduction in operational incidents also generated savings in accident-related costs, estimated at approximately US$ 20,000 per year. These results have established the project as a benchmark in underground mining, clearly demonstrating how safety and efficiency can be effectively integrated. resultado, se logró optimizar la fragmentación del mineral y reducir significativamente el valor del P80, es decir, el tamaño promedio del mineral fragmentado. La transición al nuevo sistema no estuvo exenta de retos, destacando la necesidad de una capacitación intensiva y un cambio profundo en la cultura operativa. Los trabajadores pasaron del proceso chispeo manual, retiro de personal y ubicación de vigías a ser directamente gestionado el proceso de protocolo desde una estación central, fortaleciendo notablemente la disciplina operativa. Como resultado, la exposición directa disminuyó de tres horas diarias a solo treinta minutos, representando una reducción del 85% en riesgos operativos. Los resultados en términos operativos y económicos fueron sobresalientes. La disciplina en las operaciones mejoró, aumentando el cumplimiento de los protocolos del 75% al 98%. Además, el tiempo de la voladura se redujo de 60 a 15 minutos, lo que posibilitó aumentar la producción de 5,900 a 6,150 toneladas por día, un incremento del 5%. También se lograFigura 1.
