Abstract

The extraction of aggregates in Cuba represents a fundamental mining activity for the construction industry given the volumes of materials moved within a year in the quarries being exploited in the country. These quarries have been exploited according to the project designed for this purpose. This has accordingly resulted in the selection of rock digging methods without proper knowledge of the factors influencing the process. This investigation is carried out applying a procedure based on the structural characteristics of the massif; the identification of the mechanical properties of the rock; the geo-mechanical indexes (RQD, RMR) the definition of the geomechanical domains and the selection of the most rational method. The application of this procedure identifies the most rational rock digging methods to be used in the ore body under investigation; which are as follows: extremely hard scarification and blasting.
