Abstract: In view of the problem of ground pressure control in the final mining stage of super long and large mining height fully mechanized mining face, this paper adopts the methods of theoretical analysis, numerical simulation and field test to determine the corresponding technical scheme of ground pressure regulation by studying the distribution law of surrounding rock stress and the characteristics of ground pressure manifestation in the final mining through stage of 112201 working face in xiaobaodang coal mine. It can effectively control the periodic weighting step distance of the working face in the final mining stage, maintain the stability of the roof strata, and realize the smooth laying of the flexible plastic net (15m wide×360m long) in the working face. The results show that: during the last mining period, the stress of the surrounding rock in the withdrawal channel will be transferred from the mining side to the pillar side. Strengthening the support strength of the surrounding rock of the withdrawal channel can ensure the stability of the withdrawal channel.By adjusting the mining speed of working face, the position of periodic weighting can be changed and the duration of weighting can be reduced. It can achieve the smooth hanging and connection of the working face, which has reference significance for the smooth withdrawal of similar working face equipment.
