Abstract
El objetivo de la presente investigación es determinar la rentabilidad de la estabilización aplicando
pernos tensionados de adherencia mixta en tipo de roca III-B, rampa Fabi 3, mina Poderosa;
mediante la mecanización, técnicas y monitoreo antes, durante y después de cada actividad en el
ciclo de minado. La investigación que se ha desarrollado es de tipo aplicada – descriptiva. La
población estuvo conformada por 363 pernos tensionados de adherencia mixta en tipo de roca
III – B, mina Poderosa, y como muestra se tiene 78 pernos tensionados de adherencia mixta en
tipo de roca III – B, rampa Fabi 3, mina Poderosa. Los resultados obtenidos fueron que aumentó
la rentabilidad de la empresa en un 28.14%, pasando de US$ 270.75/m lineal a US$ 346.95/m
lineal, con la reducción de los descuentos y penalidades en un 100% en estabilización por pernos
no tensionados y con deficiente capacidad de carga a falta de un torque óptimo, así como la mejora
en un 56.7% en el cumplimento al programa mensual de avance, gracias al incremento del
rendimiento en avance por perforaciones de 8 pies, obteniendo mejoras en las valorizaciones
mensuales por cada actividad. Llegándose a la conclusión que la implementación de la
mecanización, técnicas y monitoreo en las actividades del ciclo de minado es beneficioso para la
empresa ya que disminuye las pérdidas económicas y tiempos de ejecución; e incrementa la
rentabilidad y el rendimiento en las operaciones de estabilización y avance.
The objective of this research is to determine the profitability of stabilization by applying tensioned bolts with mixed adhesion in rock type III-B, Fabi 3 ramp, Poderosa mine; through mechanization, techniques and monitoring before, during and after each activity in the mining cycle. The research that has been developed is of an applied-descriptive type. The population was made up of 363 tensioned bolts of mixed adhesion in rock type III – B, Poderosa mine, and as a sample there are 78 tensioned bolts of mixed adhesion in rock type III – B, Fabi 3 ramp, Poderosa mine. The results obtained were that the company's profitability increased by 28.14%, going from US$ 270.75/linear m to US$ 346.95/linear m, with the reduction of discounts and penalties by 100% in stabilization for non-tensioned bolts. and with poor load capacity due to lack of optimal torque, as well as the improvement of 56.7% in compliance with the monthly advancement program, thanks to the increase in advance performance through 8-foot drilling, obtaining improvements in the monthly valuations per each activity. Reaching the conclusion that the implementation of mechanization, techniques and monitoring in the activities of the mining cycle is beneficial for the company since it reduces economic losses and execution times; and increases profitability and performance in stabilization and advancement operations.
