The objective of the study was to optimize the linear advance in SN-0342N, Hercules Zone UM Lincuna, by analyzing the design of the drill and blast mesh using Holmberg's methodology. The applied methodology is implemented. The sample consists of the preparatory works carried out in level 18, Hercules Zone, UM Lincuna. The instruments used for data collection were an observation guide and documentary analysis. The results suggest that the new design consisted of 34 drills, including 3 relay drills, 1 starter drill, 4 drills in the first, second, third and fourth quadrants for each quadrant, 4 gable-assist drills, 5 crown drills and 5 drag drills. Prior to design optimization, its linear advance of 2.83 m, but was increased by 3.25 m, achieving an improvement of 0.42 m of linear advance, in its the monthly cost was $23,970, which increased to $143,820 over six months and $287,640 annually. Subsequently, the monthly cost was reduced to $20,610, which increased to $123,660 over six months and $247,320 annually. It has been determined that linear progress and drill and blast costs have been optimized as a result of the new mesh design, which was applied according to the Holmberg method.
