Based on the mining condition of thick ore in the depth of soft rock, hyperbolic functions method is applied to analyze the rock mass displacement and deformation due to the underground mining of ore deposit in this paper. A theoretical model for predicting rock mass displacement and deformation due to mining of thick ore are given in this paper based on hyperbolic tangent function. And rock mass displacement and deformation in Mou-mine in China are analyzed by using the model. The comparison between the above theoretical values and the results obtained from the probability integral method as well as the data points is satisfying. The results have shown that the hyperbolic tangent function method is the same with analyzing the problems of rock mass displacement and deformation resulted from the deep underground mining of metal mine.
