Abstract The tectonic stress is one of the key factors that affect the mining subsidence, and it is also the key factor of the tectonic environment theory. In this paper, the corresponding mechanical model was established by Ansys and FLAC, and the numerical simulation tests under different structural stresses were carried out. The results showed that the ground deformation and stress variation caused by different stress distributions were different, and the damage degree and influence range of the ground varied greatly. Through the analysis of the influence of tectonic stress on coal mining subsidence, it had practical reference value for engineering planning and geological disaster prevention.
