%X The strata movement falls into four phases. Different mechanics models are used to simulate the strata movement in different phases. The differential equations are derived for strata movement models in different phases. The boundary conditions of each model and exchange conditions between different models are put forward. The visual computing program is developed to compute movement of strata and surface,position of bed separation,caving height of mined rockmass and caving step length of roof. The model has been proved by comparison with field data.
