Abstract：
After 215 blocks of K6, K7 and K8 lead emulsion chambers of the Mt. Kanbala experiment are carefully scanned, 111 muon events with zenith angle M (=tgθ) ≥ 2.5 are found. The energy of muon showers are determined by saddle-shape curves. The intensity of muons, the shower energy spectrum and the zenith angle distribution of muon showers on the altitude of 5500 m above sea level are obtained in the energy region E_μ ≥ 2 TeV. Meanwhile, the simulation calculation is made in order to study the behavior of muons inside the emulsion chamber. The results of the simulation are basically in agreement with the experiment.
