摘要：In the process of coal seam mining, the surface will have different degrees of subsidence, which willhave a severe impact on the local ecological environ- ment. Therefore, exploring a reasonable environ- mental management plan is conducive to the restora-tion of the local ecological environment and condu- cive to the lives of residents. For this reason, by con- structing a fluid-solid coupling model for analysis of surface subsidence caused by coal seam mining, the evolution of surface subsidence is explored, and the surface subsidence conditions under different road- way width conditions and the influence of ponding fish farming on the deformation of shallow surface compaction are analyzed. The results of the study found that: (1) Yield instability and collapse of the stratum mainly occurs near the four corners of the roadway, which is mainly due to different degrees of stress concentration near the four corners ofthe road- way; (2) Surface subsidence during coal mining will increase with the increase of coal mining width. When the width of the roadway is 100m, the surface subsidence is 1.73m, and when the width of the road- way becomes 200m, the maximum surface subsid- ence has risen to about 2.93m; (3) The compaction of the shallow surface in the subsidence area will in- crease with the width of the roadway. The increase of fish is affected by the accumulation of water and fish farming. When the width of the roadway is 100m, the maximum surface deformation is 26.63cm. and when the width of the roadway is 200m, the maximum surface deformation of the subsidence area is 43.91cm. The research content of this paper can provide theoretical support for the design and optimization of the environmental treatment plan of the coal mining subsidence area.
