ABSTRACT

Research of rock disintegration has been of long-time tradition at the Institute of
Geotechnics, Slovak Academy of Sciences in Kosice. At first, the rock fragmentation
process by disc cutters was studied using the laboratory large-diameter cutting rig.
Knowledge from our research was used for development of monitoring systems. The
latest versions have been applied at full-face tunnelling machines to excavate the
exploratory adit of Branisko and Višnové-Dubná skala. No other tunnel boring machine
has been used since 2002 to construct a tunnel in Slovakia. At present, drill-and-blast
conventional methods are used in tunnel construction in Slovakia. Our research
continues in theoretical study of mechanical rock cutting.
We present our research results from full-face tunnelling. The paper deals with analysis
of data acquired from monitoring of the excavation of the Branisko tunnel exploratory
adit. Mathematical modeling methods are outlined, and the results of statistical data
processing and the application of fuzzy modeling in processing of datasets acquired
from the monitoring process of excavation by tunnel boring machine are presented in
the contribution.

Keywords: Tunnel boring machine, computer monitoring system, mathematical
