This work presents a proposal for the characterization of the UnconfinedCompressive Strength test (UCS), through a series of operations that can be carried outwithout inconvenience in the field. Initially, fresh rock samples are obtained from outcropsin the area and specimens of specific dimensions are made. After the test specimenelaboration phase, crushing and granulometric classification tests are carried out witha set of specimens and in parallel with a second group, UCS tests are carried out. With theresults, the rock is characterized by graphing granulometric curves and in this graph theareas 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 inevitableto send rock samples to laboratories, thus saving time and money for the mining project.
Keywords: compression, crushing, granulometry, rock.
