Abstract: Mine water hazards exhibit multi-dimensional and compound risk characteristics. Fully mechanized mining faces are confronted with multiple types of water hazards such as roof water inrush, fault water, and bed-separation water, making safe and efficient mining under complex hydrogeological conditions a challenging problem for the coal industry. Integrating geological exploration with production practice, we investigate the features of unstable coal seam occurrence, developed faults, and complex hydrogeological conditions in the fully mechanized mining face, and analyze the disturbance factors of water-sand coupling inrush in thin bedrock and weakly cemented strata. The process pattern of mining-induced fracture and bed-separation water-conducting channels is obtained: the maximum height of the caving zone in the No.2 coal seam is 16.50 m, and the maximum height of the water-conducting fractured zone is 76.01 m. The normal water inflow of the working face is Q = 245 m³/h, the maximum water inflow is 343 m³/h, and the total amount of roof water drainage reaches 5.492 million m³. The study proposes drilling-mining collaborative exploration, dynamic adjustment of mining technology and roof management measures (adjusting the inclined length of the working face from 273 m to 243 m and reducing the mining height from 3.2 m to 2.6 m), as well as mechanical separation of coal slurry and manual desilting. An innovative control system of "geological prediction-process regulation-emergency support" is established.
