ABSTRACT Being the Mining Industry one of the most important extractive economic activities in the country. Methods are constantly being implemented, ways to optimize each one of the unit activities carried out in said activity. Drilling and Blasting is a fundamental pillar in mining, since in order to obtain good production rates at lower costs it is necessary to have an adequate control when carrying out said activities, so as not to generate excessive costs when producing ore. The objective of the present investigation was to improve the parameters of drilling and blasting with the purpose of optimizing operational costs in the company Minera Santa Luisa. It was hypothesized that improving these parameters will not only reduce operational costs, but also lead to a higher production of ore and better control and use of explosive charges. To verify our hypothesis, the design of a new perforation mesh was made, with different parameters, thus standardizing a perforation mesh of 4.00mx3.80m section, with a drilling efficiency of 3.90m, having a total distribution of 35 drilling holes. production, 3 relief drills, 1 mouth breaker and 4 relief drills for the care of the contour walls. After the blasting projects were executed, the results obtained were favorablein the operational costs of drilling and blasting there was a saving of 15US $ per shot in the consumption of explosives, there was an increase in the second half of the production of 5600 tons, thanks to a greater advance of 218.87 m. The load factor was 2.38 Kg / m3, lower than the one used before 3.51 Kg / m3. The granulometry obtained indicated that more than 80% of the material obtained passes through a sieve of 7.459 in. according to mine requirements. Therefore, the present work justifies that by improving the parameters of drilling and blasting, the company Minera Santa Luisa will obtain better productivity indexes and a greater economic benefit.
