INDEX AS A MEASURE OF THE QUALITY CAPABILITY EVALUATION PROCESS INPUT QUANTITIES OF ROCK EXCAVATION

Experimental stand for Slovak Academy of Sciences (SAS), Institute of Geotechnics is used to study the disintegration of rocks, the mechanism of mechanical disintegration and disconnecting tool attrition for more than thirty years. During these years in various fields of science and technology came to some revolutionary changes that could not remain without response in this field of science. Non-standard methods of identification were the motivating factor for re-increase of measurement accuracy. Further research was therefore focused on increasing the precision and measurements accuracy of input and output variables. Because the stability of input variables crucially affects one of the experiment determinants, a way was sought to numerically evaluate the measured values by a quality indicator especially in application for rock disintegration processes.
