ABSTRACT

Contribution work out of the problem for rocks disintegration process operation by rotary drilling, where objective function is to minimize specific energy of the rocks disintegration. Proposed operational algorithm is based on continuous evaluating of associated vibrations, on grounds of current disintegrated rock is classified to relevant
class from classes, which are defined in advance. For each of classes are expertness specify parameters for effective drilling. Individual rocks are interpreted by associated vibrating signals from the drilling process as a vector in infinitely complex Hilbert’s space. Solution is based on the knowledge of the functional analyses and on the methods of the artificial intelligence.

Keywords: rotary drilling, vibrations, Hilbert’s space, functional analyses
