【Abstract】 Safe mining of close coal seam groups is an important direction for efficient coal development, facing challenges such as complex geological conditions and significant inter-seam interaction. The research results on mining methods and methods, coal pillar setting, roadway arrangement and support technology of the close coal seam group are summarized and analyzed, and it is pointed out that there are theoretical bottlenecks such as unclear mechanisms of upward mining,insufficient optimization of complex geological parameters, and weak support synergy mechanisms at present. In the future, it is necessary to deepen the research on the destabilization mechanism of the overlying key layer, the stress regulation of coal pillars with large inclination angles, and the mechanism of support synergy so as to construct a theoretical system of safe mining. The results of this research provide a systematic theoretical framework and technical path for the safe and efficient mining of close coal seam groups.更多还原
