Abstract:

Regular changing of pressure drop in gas-air mixture is considered in conjugate sections of the vacuum gas pipeline network at moisture collections and at different degrees of flow section overlapping in the gas drainage pipeline. Conformities to the law, linking a thickness and extent of accumulations of tiny liquid with their volume on the interface of areas, are represented, allowing to determine the size of losses of pressure taking into account distributing of phases in the section of pipeline. The basic methods of calculation of mine ventilation and decontamination networks are considered.

Keywords:

coefficient of hydraulic friction, coefficient of local hydraulic resistance, pressure drop, moisture collection, degassing pipeline, methane-air mixture.
