The fundamentals of a methodological approach to solving the problem of creating safe conditions for underground mining are presented based on modeling the process of formation and accumulation of methane in working areas of coal mines, taking into account the requirements of regulatory documents in the subject area. The development of the method was carried out using data from field (applied/practical) experiments obtained at several mines of the Pechora coal basin. Determination of methane accumulation locations was carried out using the FlowVision and SolidWorks Flow Simulation application software systems. A comparative analysis of the obtained simulation results in the above-mentioned programs allows us to conclude that the results obtained are practically convergent when identical boundary and initial conditions are specified at the input to the model. Based on the results of the data obtained, it was suggested that mining equipment influences the process of formation of methane accumulation sites
