The molecular structure of methane in slitlike pores of coals from 15 to 38 Å wide is studied by the Monte Carlo method in the framework of grand canonical ensemble over wide temperature and pressure ranges. It is shown that the microscopic structure of the adsorbent surface can have a significant effect on the mechanism of pore filling. Parameters of the liquid-vapor two-phase equilibrium at the temperature 111 K are determined.
