The planning and design of underground mines are essential for the efficient extraction of minerals located at depths inaccessible to open-pit mining. These operations include elements such as galleries, ramps, and chimneys, designed to maximize the recovery of economically viable minerals and minimize waste material. Each deposit requires a specific excavation model, taking into account factors such as safety, profitability, environmental and social impacts, as well as the geological and operational characteristics of the site.Underground mining offers significant advantages, such as lower waste production, reduced environmental impact, lower restoration costs, and higher extraction precision. However, it also faces challenges like longer production times, restrictions on mineral grade ranges, selective methods with limited production rates, ventilation and stability considerations, and higher energy consumption per ton. Designing underground mines requires detailed planning of geometry, support systems, access points, transportation logistics, and ventilation and drainage systems.The design of underground mines pursues key objectives, such as defining the physical architecture of the deposit, designing support structures like pillars and walls, planning transportation logistics, calculating critical factors like dilution and recovery, and establishing safety and economic profitability standards. Additionally, integrating production schedules and ensuring the efficient use of machinery and infrastructure are essential to guarantee long-term operational viability.In recent decades, underground mining has gained relevance due to the depletion of surface deposits, the need to reduce environmental impacts, and public opposition to visible operations. This shift is driven by technological advancements enabling safer and more sustainable operations. Trends include modular projects with limited initial production and progressive expansion to manage risks. Modern practices have optimized methods like Sublevel Open Stoping and Cut & Fill, achieving higher productivity and lower operational costs while minimizing risks and fostering coexistence with local communities.
