Package CORSIKA and new approximation of primary cosmic rays has ben used to estimate the muon energy spectra D(Eμ). Models EPOS LHC, QGSJET-01, QGSJETII-03 andQGSJETII-04 has been used. Energy interval for muon spectra Eμ=10**2 — 10**5 GeV Energy interval for primary spectra (p, He) E=10**2 — 10**7 GeV; Statistics N0 from 10**6 to 10**3 Aditional statistics 10**6 in energy interval (0,01-1)·E0 The calculations of E.G. Berezhko & H.J. Völk has been exploited for the approximation of primary cosmic rays Primary protons and helium nuclei takes the most significant contribution (~99%) to muon spectrum at energies Eμ=10**2 — 10**5 GeV.The EPOS LHC, QGSJET-01, QGSJETII-03 and QGSJETII-04 models show the deficite of muons by factors ~1,7 — 2 at this region. The production of the most energetic π and K mesons in hadron interactions is suppresed by the same factors.All models predict considerable deficit of high energy particle production.
