THE RESEARCH OF STRATA MOVEMENT SCOPE BASED ON FUZZY BP NEURAL NETWORK IN UNDERGROUND METAL MINE

The influencing factors of strata movement in underground metal mine are not only complicated but also fuzzy to some great extent, and it is very difficult to predict the scope of strata movement with other methods. In this paper, the prediction method of strata movement in underground mine is put forward in which fuzzy neural network is applied. The results show that there is a strong nonlinear mapping between the select factors and strata movement angle, the anticipant and the actual output results are very similar. It is proved that the numerical value of movement angle has much in common with the select factors in theory. And the scope of strata and surface movement due to mining can be predicted.
