    The authors discuss the mechanism of interaction between dust coal and gas flow. The characteristics of two-phase flow are studied with regard to energy of expanding gas at the stage of outburst propagation using the developed method of numerical modeling. The mechano-mathematical method is verified in the wind tunnel tests of dust coal and gas flow. The comparison of the experimental and modeling data show satisfactory agreement in description of two-phase coal dust and gas flow under outburst with formation of shock waves attenuating in the line of the flow. The volume concentration of dust coal in two-phase flow essentially influences the process of the outburst shock wave attenuation.
