Improving the capacity of mine degassing pipelines

Purpose. To identify features of methane-air mixture flow within the steel degassing pipelines as well those ones made composite materials, to develop engineering solutions improving their reliability for actual use. Methodology. solve problem increasing capacity mine pipelines, an analysis fundamental studies on physical and mechanical properties methane processes its recovery in a environment is conducted. Schemes operating gas-transmission systems peculiarities functioning zonal vacuum gas conditions intensive removal rocks bottom underground workings deformations massif are considered. Based results expert assessment production situations, potential reserves enhancing efficiency in-mine have been determined. Reliability indicators traditionally applied pipes analogues from materials used abroad established, innovative technological technical construction at Ukrainian mines recommended. Findings. According evaluation operation modes lines world practices apply mining industry, solution concerning improvement has substantiated. Originality. Innovative modernization systems, which allow provide maintaining quality captured process transportation wells pump stations, Practical value. Implementation research decrease hydraulic resistance mains introduction main long links with minimum number butt joints scheduled dealing development gassy coal seams.
