A new procedure for analysis of the stressed state of gas pipelines in mine production zones was created. The effect of relaxation of the forces of interaction between the surface of the pipeline and the soil is considered. The method of experimental study of the processes of relaxation of forces of interaction between the surface of the pipeline and the soil in time is worked out. The algorithm of taking into account the load history and the simulation of the stressed state of main gas pipelines, which take place in the zones of mine workings taking into account the history of load time, is developed.5481 Product Description popup.authors Агеєв Сергій Михайлович Батура Анатолій Сергійович Богдан Андрій Васильович Дубик Ярослав Романович Ориняк Ігор Володимирович popup.nrat_date 2020-04-02 Close
