Based on probability integral method and the moving deformation estimated,the basic principle of the surface arbitrary point and dynamic forecast model,combining the geological mining conditions in the study area,this study analyzed the results of surface movement deformation prediction in study area at different stages. Combining the relationship of pylons and the underground work face with the above results,this study analyzed the results of surface moving deformation prediction under the high voltage line towers at different stages.Then this study compared the results with transmission lines operating standards,analyzing the security of pylons to complete the expected research to ensure the safe operation of the line. And regular patrol work is necessary during mining. The results shows that probability integral method is better to complete the moving deformation prediction of high voltage line towers at different stages. And the results of prediction has a great guiding to the safe operation of pylons.
