CHARACTERIZATION OF THE UNCONFINED COMPRESSIVE STRENGTH TEST IN ROCKS BY FINE GRANULOMETRY

Descripción:

This work presents a proposal for the characterization of the Unconfined Compressive Strength test (UCS), through a series of operations that can be carried out without inconvenience in the field. Initially, fresh rock samples are obtained from outcrops in the area and specimens of specific dimensions are made. After the test specimen elaboration phase, crushing and granulometric classification tests are carried out with a set of specimens and in parallel with a second group, UCS tests are carried out. With the results, the rock is characterized by graphing granulometric curves and in this graph the areas of fine granulometry are focused, inserting in these areas, the average value of UCS, with which it can be identified and determined when it is really necessary and It is inevitable to send rock samples to laboratories, thus saving time and money for the mining project.
