• Abstract: As the shallow coal resources in China are increasingly depleted, close-distance coal seam mining has become the mainstream mining mode in many mining areas. However, the small spacing of close-distance coal seams leads to significant mutual disturbance during the mining process, resulting in intensified stress concentration and large deformation of surrounding rocks, which seriously restricts the safe and efficient mining of mines. This paper reviews the research status of mining pressure control technologies for close-distance coal seams. It elaborates on the engineering background of close-distance coal seam mining and the core significance of mining pressure control, and summarizes the relevant research progress and existing deficiencies at home and abroad; it also summarizes the principles, application effects and applicable scenarios of four major core mining pressure control technologies, namely, optimization of mining parameters, reinforcement of support, pressure relief control and monitoring and early warning.
