Abstract. Today, methane, being one of the most perspective potential sources of energy, is at the same time a source of constant danger for miners and one of the largest polluters of environment. The purpose of this scientific work was to develop a methodology for calculating parameters of the ground degassing gas-transport system and technical solutions, which could improve safety of operation, immediacy of control parameters and energy-efficiency of management. For proper usage of the borehole output pressure, a scheme of reconstructed ground gas- transport system (GTS) was developed with using of existing gas-pipeline, diameter 325 mm. On the basis of the research results, a simulation model was developed for designing and studying the ground degassing systems (GDS). With the help of this simulation model, the mines’ specialists can calculate the borehole pressure and consumption necessary to ensure the needed gas voume for cogeneration unit and automobile gas-filling compressor station (AGFCS). It is also possible to control pressure in the key points and loss of pressure in the gas-main pipeline sections.

Keywords: pipeline transportation system, boreholes, pressure.
