The study analyzed the deformation and failure of overburden strata above mining blocks in Linnancang Mine using advanced software. Mining in No.11 seam caused a max subsidence of 2.75m and plastic yield failure up to 31m. Mining in No.12 seam resulted in a max displacement of 5.42m and potential plastic yield failure up to 47m.
