Abstract. The experimental data of the Andyrchy-BUST experiment are presented. The three types of
experimental data, taken in our experiment, have been analyzed: high energy muon number spectrum, EAS size
spectrum and dependence of the mean number of high energy muons on EAS size. Joint analysis of these
experimental data have been used for both studying the primary composition and testing interaction models.
