Abstract：
A Monte Carlo simulation on production characteristics of high energy family events observed with Mt. Kanbala emulsion chambers is made based on hadronic interaction models QGSJET and DPMJET with program CORSIKA which is commonly used in the simulations of EAS experiments. The production efficiency of family events for different primary particles and its relationship with primary energies are given. The distributions of lateral spreads, numbers of showers, total visible energies of the family events and their corresponding average values got from simulations are systematically compared with those of the experiment. It shows that their results are consistent basically. Additionally, family events from both simulations and experiment have the similar tendency of energy concentration.
