The objective of this thesis is to determine the development of the new 16-foot drill mesh, to replace the existing 12-foot drill mesh, and thus determine the economic feasibility of changing the drill mesh for development work in the Immaculate UO. The methodology of this thesis consisted of determining the geomechanical properties of the rock mass, then the technical-economic evaluation of drilling and blasting activities was carried out in development work. (“data collection in the field”) For the existing 12-foot mesh, the 16-foot mesh was subsequently implemented in these tasks, also carrying out a technical-economic evaluation of said mesh. To conclude, a comparative table of the data obtained in the technical-economic analyzes of the two different meshes was prepared The predominant rock in the study area was determined to be type (IIIB), mostly “Andesitic” with a GSI of 50 and an RMR of 55 on average. The results obtained after the comparison between the two drill screens are as follows: Advance by blasting on the 12-foot mesh is 3.19 meters per shot, the advance on the 16-foot mesh being 4.29 meters. Blasting efficiency in the 12-foot mesh was 96.84% vs. 97% in the 16-foot mesh. The volume broken in the 12-foot mesh was 56.58 cubic meters against the 76.05 cubic meters obtained from the 16-foot mesh. The broken ton for the 12-foot mesh was 144.84TM versus 194.69TM as a result of the 16-foot mesh. Steel cost per shot in the 12-foot mesh was 810,866 ($ / m) against 1051,247 ($ /m) in the 16-foot mesh. Steel cost x drilled feet resulted in the 12-foot mesh of $ 0.057 versus $ 0.05 in the 16-foot mesh. To conclude this thesis, it seeks to encourage students to develop and implement new techniques for carrying out controlled blasting, applying a drill mesh that generates greater profitability.
