Basing on the data of field station for earth movement observation in the new mine of Huainan,this paper revealed the main limitation of the probability-integral applied in thick alluvium areas and proposed a modified model with mathematic expression.It had been verified that the new method could overcome the limitation of boundary fitting with errors,make the error distribution more homogeneous and improve the accuracy of mining subsidence prediction with the probability-integral in thick alluvium areas.
