Abstract：
The energy spectra of cosmic ray hadrons is studied by use of mountain emulsionchambers installed on Mt. Kambala 5500 m above sea level. The power index. of theenergy spectra is 1.95±0.18 in the energy region from 3 to 50 TeV The verticalflux of hadrons with E _h ^γ≥3 TeV is (145±14)/year.m ².sr, their attenuation lengthin air is (101±13)g/cm ², and mean interaction length in Pb is (187±51)g/cm ².
