Optimization of rock disintegration using the acoustic signal

Abstract

Rock disintegration is one of the most important operations of mineral resources excavation and treatment technologies. This paper deals with a possibility of rock drilling optimization by acoustic signal. During the disintegration process, the thrust of the drilling tool, revolutions, drilling speed and disintegration power have been monitored. Within the co-operation with the Department of Applied Informatics and Process Control of the BERG Faculty of Technical University Kosice, a system for noise monitoring during the rock disintegration has been designed and mounted. This paper analyses experiment results for disintegration process optimization with use of acoustic signal.
