The present work was carried out with the purpose of designing a drilling and blasting mesh for the application of the method of exploitation Sublevel Stoping in narrow veins in a rock type III and IV (According to the classification of Bienanski, 1989). The need to make an optimal design of the perforation mesh was born when, by means of geomechanical study and a numerical analysis, it is concludes that the Daniela vein in the 'G' corridor could be exploited by the sublevel stoping method, where made an in-situ data collection and came to the conclusion mainly of placing bolting cables in the roof box and that we have to contemplate the use of controlled blasting for our mesh design since the foot wall has an RMR equal to 34 , the hanging wall 41 and the lode 54, that is to say rocks type IV, III and III respectively (According to the classification of Bieniawski, 1989). Now, uslng the Pearse model, slmulatlons are performed to calcúlate the burden, vital in the elaboratlon of the mesh, and then, by means of other charge slmulatlons, the ldeal way to carry out the charge of holes ls reached. Flnally, an analysls of technlcal lndlcators obtalned by applylng the deslgned drllllng and blastlng mesh, furthermore comparlson ls made of the lndlcators when uslng the seml-mechanlzed cut and flll method wlth the mesh standard of the Mlnlng Unlt.
