摘    要：本文从非线性影响的概念出发,导出了地表移动中指数函数法的二维动态公式,并对a,b等参数的解法作了讨论。文中以实际算例对各公式进行了检验,得出了有实际意义的结果。

Abstract: In accordance with the concept of nonlinear influence, the author derived the formulae for prediction of dynamic subsidence trough which were based on the exponential function method. In this paper, the solutions of the calculation parameters, which characterize the strata and extraction conditions, were discussed. The comparison of calculated and observed results shows that time effect of subsidence and variations of the parameters should be taken into consideration in predicting the ground movement due to mining. The horizontal movement factor B will increase with-time. This phenomenon has been verified by the data observed in Pingdingshan Mine.
