Standard Specific Drilling Energy of the Acoustic Signal for Identification of Indentor-Rock System

Abstract

Current computer techniques provide new modern utilization and approaches in processes that have not been used. One of such possibilities is a design of models for optimization of rock excavation process. The qualities of the model derived from conventional energy theory of rock drilling are compared to the qualities of non-standard model obtained by scanning of the acoustic signal as an accompanying effect of environment in the rock drilling process. The paper focuses on the signal energy, as one of type energy transformed by rock drilling process. The acoustic signal was registered on the laboratory drilling stand at the Institute of Geotechnics SAS in Košice.
