Abstract: A pit slope is a human-made slope, which is a product of long-term dynamic process of excavation or extraction. Under certain circumstances, landslides are allowed within a specified range. Therefore, remediation of landslides is to assure the successful extraction of ores during the designed life time of the mine. This paper presents new concepts of a dynamic comprehensive method for remediation of landslide disasters of open pits. The paper then uses the case study of control of landslide disaster at Panluo open-pit iron mine to demonstrate the analysis procedures and applicability of the method.
