Abstract The surface deformation expected rock movement parameters and geometric parameters were got through measured data and related information in Xima Mine, the expected method and software of surface movement deformation were chosen. Surface deformation of working face like paste filling after mining was expected by probability integration method. Comparing expected analysis result with oil pipeline protection standards, the result showed that the scheme can ensure the normal use of oil pipeline.
