Abstract.

The dynamics of seepage of liquids through porous materials is described by the Darsy equalization, here transmissivity of hard environment is determined by effective or opened porosity of array, which participates in the process of flow of the squeezed or incompressible liquid under action of the attached gradient of pressure. Emptinesses in a hard environment are different on sizes and form and is distributed in an array chaotically. Therefore for the design of porous environment the elements of theory of the multipolar systems, describing motion of liquid or gas in the elementary volume of array and current oriented on lines from an initial knot in eventual one under action of the attached gradient of pressures, are applied. Application of cluster model allowed to divide the produced space into elements in which different modes of motion of methane-air mixture are observed from lamynar to turbulent and to take into account influence of facilities of газоотсоса on degassing of the produced space.

Keywords:

cluster model, permeability of hard environment, laws of motion of air, gasootsos, produced space.
