Abstract: Aiming at the roof control problem of super-large mining height in near-shallow buried thick unconsolidated layers represented by Yushen mining area, the theoretical analysis, numerical simulation and field measurement are used to analyze the pressure law, roof structure and strong dynamic load control method of 10 m super-large mining height fully mechanized mining face. The results show that: The roof breaking form of super-large mining height in near-shallow buried thick unconsolidated layers is a combination of “low cantilever beam (equivalent direct roof)+high masonry beam (key layer structure group)”. The instability load of high masonry beam is positively correlated with the thickness of unconsolidated layers, and decreases with the increase of bearing capacity of bedrock layer. When the base-load ratio J_z≤1.5, the influence range of “vertical stress relief zone” and “horizontal stress concentration zone” in the overlying strata will expand with the increase of the base-load ratio, and the bearing capacity and structural stability of the high-level “key stratum structure group”will gradually increase, which is conducive to the increase of the overall weighting step distance and the weakening of the weighting strength of the working face. When the base load ratio J_z>1.5, the influence of the base load ratio on the stress environment of the roof strata is weakened, the load of the high bedrock layer structure and the loose layer tends to be balanced, and the risk of strong dynamic load pressure in the working face is significantly reduced. According to the characteristics of roof structure and the pressure law of working face, the prevention and control measures of strong mine pressure are put forward: in the area of base load ratio J_z≤1.5, improving the bearing capacity of high-level “key stratum” structure is the key to reduce the pressure strength of working face. The location of the key layer should be accurately determined to avoid regional weakening measures for the key layer of the bearing structure. When the base load ratio J_z>1.5, reducing the mining height and regional weakening of the low-position thick and hard roof to improve the filling rate of the goaf will more effectively reduce the pressure strength of the working face. The research conclusion has been verified and applied in the industrial practice of fracturing strong mine pressure prevention and control in the roof area with super large mining height, and has achieved ideal results.
