The objective of the research is to design the underground mine of the mineralized deposit of "Hilarion" and to show the stability conditions of the projected excavations, in the irregular mineralized structures of Zn-Pb-Ag, located in the contact of the calcareous sequence of the Pariatambo formation, with intrusives of the "Hilarion" deposit of 1.6 km in length and 500 m in depth. The geological and geomechanical conditions of the Good Quality Rock Mass (BII) allowed the choice of "Sub Level Longitudinal Stoping" and "Bench and Fill Stoping" as mining methods. For this purpose, the criteria and parameters of the geomechanical design are defined and then the dimensions of the Basic Exploitation Units (UBEs).
