摘要

The stability evaluation of seam roof refer to many nonlinear problems of complex indexes and different fields. It is difficult to consider every index to choose the evaluation way. So, in order to solve this shorter, Getting Mine is taken for example. Based on the comprehensive analysis of main 3th seam roof stability influence factors, the stability of roof can be divided into five grades, which is from stability to instability : first rank, second rank, third rank, fourth rank, fifth rank. Then, BP ANN was proposed to establish the model. By index normalization and repeated studied of ANN, 3th seam roof stability of Getting Mine will be evaluated zonal at last.
