Abstract There are two problems in processing the subsidence data due to mining，one is the complication of the procedure to calculate the movement and deformation in the main sectional plane，the other is lack of the robust method for parameter calculation. A modified model was put forward to calculate movement and deformation in the main sectional plane based on the coordinate system conversion. A robust inversion method with the probability integral was proposed based on the principle of minimum-quadratic residual sum of moving vector，the uniform design of parameters initialized samples，Chauvenet detection of abnormal samples and the weighted pure samples. The simulated experimental results showed that the robust method for parameter calculation can also invert the precise probability integral parameters，even if the initial sample of parameters with large span (partial sample parameters gravely deviates from the true value).

Key words： mining engineering mining subsidence uniform design coordinate system transformation parameter of probability integration method
