Abstract: A prediction method of strata movement in underground metal mines is put forward in which the artificial neural network is applied, and selected factors influencing strata movement are dealt with by the fuzzy ma-thematic method. The results show that there is a strong nonlinear linking between the factors and strata movement angle, and the numerical value of movement angle has much in connection with the factors. It is proved that the scope of strata and surface movement due to mining can be predicted in theory.
