 The research aims to develop a classification method for rock types based on the vibration signal generated during experimental rotary drilling, which provides information about the rock disintegration process and drilling parameters. The proposed method uses a decision tree and achieves 100 percent reliability in classifying three rock types in concrete from a one-quarter S signal record.
