The issue of accounting for the accumulation of liquid in the mine degassing network during gas-dynamic calculations is considered. Geometry of fluid accumulation in the cross section of degassing pipeline and the formulas for geometric parameters are presented. A scheme of wave generation on the liquid surface is considered. Dependence for the coefficient of resistance to interfacial friction on the liquid surface is proposed. Formulas for calculation of gas-dynamic parameters on the pipeline section are given. The results calculation of the resistance coefficients in the place accumulation of liquid, changes in flow and pressure of the gas mixture are presented. Calculations carried out for pipelines with accumulations of liquid.
