Operational continuity with respect to the environment
Optimization of mineral resources
Agroindustrial Delta de Minas, headquartered in Sete Lagoas, Minas Gerais, extracts and refines non-metallic minerals for cement production. With the purpose of ensuring operational efficiency and optimizing the use of mineral resources, the company needed to find a viable solution to blast an 18-meter long bench near an environmentally-protected cave. The goal was to ensure operational continuity while strictly adhering to environmental legislation.
“We are entirely satisfied with the results, bringing agility to the development of this area of the mine. We gained productivity, as we greatly reduced the number of times we had to remove the equipment prior to blasting, bringing profitability and less equipment wear and tear for us, which was fantastic. We went from a vibration of 10 mm/s to 3 mm/s with this new technique.”

Advanced controlled blasting technique
Enaex, a supplier of blasting products and services, provided consulting and offered an appropriate solution to address the challenge. The technique adopted involved conducting a single blast using two decks per hole with differential timing. This allowed for the controlled detonation of the bench, resulting in minimal vibration levels. Through this approach, it was possible to extract the high mineral content material without compromising the integrity of the environmentally-preserved cave.
For precise implementation of the solution, Enaex used DaveyTronic OP® electronic detonators and pumped emulsion through a Mobile Pumping Unit (MPU). The emulsion density was controlled to achieve the desired outcomes. Additionally, Enaex’s specialized workforce played a crucial role in the successful execution of the proposed technique.
Minimal impact and increased productivity
Enaex provided technical support and operationalized the blasting to ensure the expected results were achieved. As a direct result, Agroindustrial Delta de Minas achieved higher mine productivity, eliminating the need to remove equipment from the vicinity. Additionally, the implementation of the technique resulted in a significant reduction in vibrations, from 10 mm/s to 3 mm/s, ensuring minimal impact on the structure of the cave.
As a strategic partner, Enaex was committed to minimizing the environmental impact associated with the blasting near the environmentally-protected cave. They provided specialized and customized their consulting services to meet the specific challenges faced by Agroindustrial Delta de Minas.
At Enaex, our purpose is to humanise mining by having a positive impact on all aspects of the blasting process.
