Abstract: The results of laboratory measuring of gas-dynamic parameters in the fracture during evaporation of its walls are presented. The fracture of a shale layer was simulated by a slit created in plexiglass. The fracture was blown through by gas flow, its speed was experimentally measured. The values of flow rates, evaporation speed and entrainment of the mass of material from the surface of the slit are recorded. The shall recovery factor is calculated under laboratory conditions
