Purpose. Establishing correlations between analytical and laboratory research in underground coal gasification with a focus on hydrogen production. Methodology. Analysis of experience in conducting analytical and laboratory research in the field of underground coal gasification in situ. Analysis of the application specifics of the Darcy-Weisbach equation to establish optimal conditions for supplying steam-air mixture to the combustion face considering the relationship between the volumetric flow of the specified mixture through the controlled pipeline and its cross-sectional area. Results. The proposed algorithm for conducting research on underground coal gasification processes focuses on hydrogen production. Analytical formulas are provided to determine optimal parameters for supplying the blowing mixture to the combustion front via the controlled pipeline. An author's technological scheme of a laboratory setup for studying gasification processes and the peculiarities of researching it are presented. A diagram illustrating the relationship between blowing system parameters, which vary depending on the hydrogen raw material requirements, the energy capabilities of the system itself, and the parameters of the controlled pipeline, is provided. Originality: Scientifically grounded development of a methodology for conducting analytical and laboratory research on coal gasification process to determine parameters for supplying the blowing mixture through the controlled pipeline with a focus on hydrogen production. Practical implications: Practical implications: Conducting research according to the developed research methodology of underground coal gasification technology allows for a systematic and structured approach to assessing all aspects of the gasification process. The use of a clear research methodology helps to avoid subjectivity and simplifies the process of data collection and analysis. The research methodology ensures high reliability and accuracy of the obtained data, which is critical for making informed decisions. Effective use of the research methodology minimizes resource usage, such as time, costs, and equipment, by avoiding unnecessary duplications and unjustified expenses.
