The problems on predicting geotechnical engineering disasters in mining engineering are the most important research subjects .According to the predicting problems ,the paper studied the approach for setting the training parameters and model of ANFIS by using the orthogonal test design method and the pattern search algorithm(PSA) ,and put forward and established the approach for adaptive neuro‐fuzzy inference system based on pattern search algorithm (PSA‐ANFIS) .Further‐more ,the data pairs for training ,data pairs for checking and data pairs...
