Abstract: Probability integration method has extensive application in mining subsidence prediction, while the accuracy of result mostly depends on the reliability of the parameters. This paper has a discuss on the inversion method for getting the predicting parameters using the calculation software 1stOpt for mathematical optimization, and then this method is carried out by three examples. The result shows that this method ,with simple operation and high accuracy, need not the initial value and greatly reduces the difficulty in getting the parameters.

Key words: probability integration method, predicting parameters, 1stOpt, parameter inversion
