The surface subsidence is caused by underground constructing, mining and excessively pumping groundwater. And disastrous accidents on unexpected collapse and landslide along bed plane probably occurred. Based on the stochastic medium theory and the methods for predicting ground point’s movements and deformations in any direction under folding structure strata and any shape rooms, the basic factors in varied geology and excavating were comprehensively analyzed. The formulas for predicting ground point’s movements and deformations were derived under excavating underground non-bedded shape rooms. Because the formulas for predicting surface subsidence can’t be integrated, the numerical integral method and the computer technique were adopted to calculate the values of integral equations.
