Possibility of application the statistical methods in defining the engineering geological complexes

This work presents the procedure of applying the statistical analysis methods for the needs of defining the engineering-geological complexes in the structurally complex geological conditions on the example of working environment of the open pit Gacko - Central Field. The open pits represent the exploitation objects explored over a longer period of time using the different exploration methods, in varying degrees and with different reliability, and the question of selecting the relevant values of investigated parameters is usually a complex task and crucial from the aspect of construction the exploitation objects. For the purposes of forming an open pit and determining its geometric parameters, inclination and height of the final, the system of working and general slopes and slopes of levels; a good knowledge of the basic physical-mechanical parameters of the working environment, and their values for characteristic separated units - the engineering-geological complexes is necessary. In order to present the working environment of the open pit as realistic as possible, and in the process of defining and limiting the engineering-geological complexes within a complex, only those lithological-structural units of similar engineering-geological parameters can be found, it is possible to apply the methods of statistical result analysis of geomechanical data research. The results of this analysis, in addition to the other relevant parameters of the working environment, can facilitate the separation process of characteristic geomechanical units, and enable the formation of a more precise engineering-geological model of the open pit area.
