Abstract: The lateral distribution of muons with the threshold $E_\mu\approx1.0\text{sec}\theta$ GeV (where $\theta$ is the zenith angle) in extensive air showers (EASs) with the energy $E_0\approx10^{17-19}\,$eV in various observation periods from November 1987 to June 2013 has been analyzed. The experimental data have been compared to the calculations within various models of the development of EASs from the CORSIKA package. The experimental data are in the best agreement with the QGSJET II-04 model. The mass composition of cosmic rays with $E_0<2\cdot10^{18}\,$eV before 1996 was much lighter than that in a later time interval.
