The methods and means of control for gas pipelines, as well as signs of liquid accumulation are present. Dependencies for determining the volume flow of gas mixture and the absolute equivalent roughness for internal surface of degassing pipeline is given. The graph of changes in local pressure losses of the gas mixture in the place of fluid accumulation is given. Analysis of the results of experimental studies of the aerodynamic drag of pipeline section in the place of liquid accumulation is out. Results of measurements for methane concentration in ventilation working out when stopping degassing are present.
