Abstract：In order to ensure the safe production of Tianchi Energy South Open-pit Coal Mine and avoid the loss of personnel and equipment caused by geological disasters such as spalling and landslides,based on the previous local collapse cases,the article analyzes variation law of the displacement-time curve,the average velocity and displacement in the stage of uniform deformation,studies the dynamic relationship between radar early-warning threshold and slope variation combining the technical principles and early warning principles of slope radar,and determines the four-level early warning thresholds of velocity and displacement at different acceleration stages.The results show that the four-level alarm value based on the actual cases can accurately predict the occurrence of slope deformation disasters.
