Interpretation problems of using monitored quantities in a drilling practise

Abstract

One part of the paper points the ambiguity of the relation between the strength of the disintegrated rock and the actual penetration rate of drilling. For the overcoming this ambiguity, the rock is sorted into clusters according to the prevailing mechanism of its disintegration at drilling by model tools. In paper the generalized algorithm of costs optimization function of drilling in rockmass is also defined.
