ABSTRACT

What is characteristic of any technological process as well as any equipment is its
acoustic manifestation in the course of operation. This signal is a manifestation of the
function of equipment, its condition and impacts on material treated. The acoustic signal
arises due to mechanical vibrations; the acoustic signal being, as a matter of fact,
mechanical vibration of the air.
On the basis of analysis of acoustic signals and mechanical vibration developing in the
technological process at the opencast mine, especially in the course of long-distance belt
transport, information on material mined was searched for. I have concentrated upon
signals within the audible range; it means sounds and corresponding mechanical
vibrations.
Our paper is aimed at a carried-out analysis of both acoustic signals and mechanical
vibration, which are formed within a technologic process on an open pit mine; and
special attention is paid to the material quality.
