“…The object of time and frequency analysis of the vibroacoustic response was laboratory horizontal drilling equipment. The drill stand was developed and constructed by the Institute of Geotechnics of the Slovak Academy of Science (IGT SAS) in Košice [9][10][11]. The horizontal drill stand is designed for rotary drilling of rocks with small diameter diamond drilling bits up to 80 mm in diameter [12,13].…”

The mechanical disintegration of rocks plays an irreplaceable role in the exploration, preparation, and mining of minerals resources in geological and engineering surveys. When disintegrating by rotary drilling, the disintegration tool interacts with the rock and converts the mechanical energy to thermal energy caused by the friction of the disintegration tool on the rock. Consequently, undesirable accompanying sounds occur in the process of disintegration of the rock by drilling. These include vibrations that show up in the working environment as noise. The noise generated during rotary drilling can be scanned as an acoustic signal. From above, it is possible to say that noise and vibration have a direct negative impact on the machinery personnel, on the working environment and on the environment. At present, research in the field of the disintegration of rocks by rotary drilling is directed at analyzing the factors affecting the disintegration of rocks and the working environment. This article analyzes experimental measurements carried out on a horizontal drilling tool. Measured vibroacoustic signals in different operating modes will be processed in the time, frequency, and time-frequency domains.
