The article presents the results of analysis conducted on the NEVOD-DECOR data that were obtained following the study of inclined muon bundles (θ ¼ 40–85°) of cosmic rays for the time period from 2012 to 2023. The research was executed using original method for studying the extensive air showers, local muon density spectra. The data were compared with the calculations based on the simulation of air showers using the CORSIKA program for different models of hadronic interactions. The obtained estimates of the energy spectrum and the behavior of the mass composition of primary cosmic rays in a wide energy range from 2 × 1015 to 3 × 1018 eV were compared with the data from other experiments.

Abstract
The article presents the results of analysis conducted on the NEVOD-DECOR data that were obtained following the study of inclined muon bundles (θ ¼ 40–85°) of cosmic rays for the time period from 2012 to 2023. The research was executed using original method for studying the extensive air showers, local muon density spectra. The data were compared with the calculations based on the simulation of air showers using the CORSIKA program for different models of hadronic interactions. The obtained estimates of the energy spectrum and the behavior of the mass composition of primary cosmic rays in a wide energy range from 2 × 1015 to 3 × 1018 eV were compared with the data from other experiments.
