Based on the elastic plastic finite element method(FEM), the paper gives the relation between the locations of pillar in several seams and the movements of ground and strata. The formulas for calculating the factors such as subsidence factor q, horizontal movement factor b, tangent of main effect angle tgβ, horizontal distance between pillars of contiguous seams l, distance between seams h, and accumulative thickness of mined seams m have been obtained.
