Rock Type Identification by Impact Action

Research output: Chapter in Book/Report/Conference proceedingPublished conference contribution

Abstract

Impacting systems that can move during their operation have many practical
applications in science and engineering, and there are different theoretical models describing their motion. A general issue arising for this kind of system when
applied to drilling is how to obtain optimum control parameters for high penetration rate with different types of rock. Pavlovskaia et al. [1] theoretically
showed how to model and calculate penetration rates by using a drifting oscillator. Wiercigroch et al. [2] proved experimentally for ultrasonic percussive
drilling that the material removal rate is a function of static load and has local and global maxima. Cavanough et al. [3] revealed the relationship between
static load, rotational torque, and penetration rate also in a percussive drilling
experiment. All these studies have demonstrated the existence of the optimal set
of parameters and a need for a self-optimizing control system capable of choosing
its static load to obtain optimal regime drilling conditions.
