Abstract: Probability integral method is the main method of predicting mining subsidence，and its prediction accuracy directly depends on the accuracy of the parameters.How to use the right methods to accurately and stablly calculate the expected parameters is the key issue in practical application.The probability integral method commonly used in parameter inversion is summarized and the advantages and disadvantages of various methods are analyzed.Then the global search ability of genetic algorithm applied in parameter calculation is emphatically introduced.Finally，the existing problems and the further research tasks in the probability integral method to predict parameters are put forword from the aspects of error，and principles and scope，parameters correlation in probability integral method and the nonlinear of the model.

Key words: Probability integral method, Parameter inversion, Research progress
