The overlying strata of coal seam is usually thin bedrock, so it is necessary to systematically study the thickness and movement of overlying bedrock to maintain safe mining. In this paper, taking the ZG Coal Mine as an example, the simulation study on the movement law of overlying strata in working face under the condition of high concentrated stress has been carried out. The results show that the stress distribution in the fully mechanized mining area is similar to that in the fully mechanized caving area in the collaborative mining working face, and a certain range of advanced stress concentration area is formed in front of the working face. In the process of working face advancement, the failure depth of coal wall in the fully mechanized caving area is obviously greater than that in the fully mechanized caving area. The depth of plastic zone in the fully mechanized caving area is about 2~4m, and the depth of plastic zone in the fully mechanized caving area is about 4~5m. In the process of propulsion, the coal wall gradually changes from a single shear failure to a mixed failure state including tensile and shear failure. Under the same excavation distance, the stress peak in the bottom layer area is closer to the coal wall, while the coal pillar area is closer to the front. The stress drop rate in the coal pillar area is faster than that in the lower stratified area. Due to the inconsistent state and displacement of the plastic zone in the two regions of the working face, the joint location of the two regions of the collaborative mining face has a great possibility of spool because of the different mining methods. Therefore, in the working face stoping, attention should be paid to prevent the prominent problem of pressure in this area. [ABSTRACT FROM AUTHOR]
