ABSTRACT
The process of rotary drilling of rocks induces the accompanying noise and vibrations. Such signals contain the information on the process characteristics and may be used for effective process control. The advanced signal processing involves the application of methods using the abstract mathematical space as the signal space. In application of abstract spaces, the signals are considered as functions of time or frequency. Data acquired from rotary drilling of different rock types in laboratory conditions were processed using such methods. Signal space provides a possibility to classify the rocks or the process conditions based on geometric relations with no need to extract the features and visualize them.

Keywords:rock drilling, information signals, abstract spaces, geometric relations between signals.
