  Change of the energy characteristics of muon bundles with an increase of the
primary cosmic ray particles energy can be a key to solving the problem of muon
excess in the extensive air showers (EAS) observed in a number of experiments.
In this work the data on the energy deposit of multi-muon events in a wide
range of zenith angles (and as a consequence in a wide range of primary
particles energies) obtained with NEVOD-DECOR setup over a long time period are
presented. The experimental data are compared with the results of simulations
of EAS muon component performed using CORSIKA code.
