Abstract：
Under the condition of the primary cosmic ray incidence with different composition, the multi-μ phenomena are simulated by the scaling model of the hadronic interactions included by the mechanism of jet production with large transverse momentum The results show that the primary heavy heavy nuclei contribute significantly to the large μ-multiplicity events observed at deep underground. But even the heavy nucleus dominant primary model is used, the multi-μ event rate simulated is still lower than the experimental data and it suggests the existence of other multi-μ sources. The lateral distribution of multi-μ events is in accordance with experiments.
