According to the study, the authors have calculated and determined the reasonable size of hydraulic prop support of self-advancing hydraulic roof support, used in underground coal mining in the Quang Ninh area. The study took into account various factors that are related to the geological conditions of the mine areas, the manufacturing materials, and mining technology. The results obtained from the study can be reasonably applied to calculate the suitable size of the hydraulic prop support based on the durability and stability required for coal mines with similar geological conditions as the Quang Ninh mines. The study was carried out with the aim of improving the efficiency of using hydraulic prop support and reducing product costs. In addition, the research results can be the basis for calculating other types of hydraulic prop support used as a reference for manufacturing other underground coal mining supports at Quang Ninh coal basin.
