This piece analizes the possibilities of mining exploitation in a little outcrop of rose granite.
The zone has been researched, recognizing the main structural discontinuities, and characterizing the rock mass by the geomechanic classification of BARTON. Two core drilling have been made to study the evolution of the deeper bed. The volume of the bed has been calculated by geometric calculation in the researched area. The theories of CASTAING and RABU have been developed to estimate the useful volume of the bed for a minimum block size of 1 m3. We have implerríented a computer program in base of EXCEL 4.0. The result is a useful volume of 51.67 %. By the application of the reduction coefficients of sterility and irregularity, the maximum estimated efficiency of the exploitation is 33 %.
