In the present research, the optimization of drilling and blasting processes in a narrow vein mine is addressed through the redesign of the drilling pattern using the cylindrical cut method. The importance of this stage in the preparation of a blast is identified, highlighting variables such as the burden, spacing, and type of explosives. The project analyzes geomechanical data and applies mathematical models to optimally design the drilling pattern. The methodology includes the collection of historical data, consultation of theoretical manuals, and the use of technological tools such as Excel. Specific parameters are designed considering the type of rock and geological conditions. The contrast between the theoretical results of the current pattern and the proposed one allows for evaluating the effectiveness of the new design. The importance of ensuring safe working conditions according to mining industry standards is highlighted. An economic analysis compares the proposed design with the current one, demonstrating economic viability through a significant reduction in costs and an improvement in the efficiency of drilling and blasting processes. To evaluate economic viability, the drilling and blasting costs of the current design were contrasted with the proposal. With the new design, drilling costs per blast were reduced from 3,559.81 USD to 3,552.98 USD, achieving a saving of 6.83 USD per blast. This reduction was achieved by decreasing the diameter of the relief hole and eliminating a relief hole. There is also a reduction in blasting costs per blast from 211.80 USD to 160.76 USD, thanks to changes in materials and the initiation system. In conclusion, the implementation of the proposed design optimizes drilling and blasting processes, reducing costs and improving operational efficiency, while ensuring compliance with occupational health and safety standards
