Abstract：To address issues in traditional open-pit mine slope monitoring and early warning,such as limited monitoring technologies,inadequate multi-source data fusion,and ineffective early warnings,this paper reviews the research progress in slope disaster monitoring and early warning from three perspectives:intelligent slope sensing and monitoring,high-precision 3D slope modeling and visualization,and slope stability assessment with risk warning.The monitoring methods,including the Global Navigation Satellite System,the integration of UAV oblique photography with LiDAR,and multi-scale sky-air-ground integrated monitoring,are systematically summarized.Cutting-edge technologies,such as 3D visualization and modeling of complex geological structures,as well as digital twin-driven full-element 3D visualization of slopes,are reviewed.Key technologies,including machine learning-driven intelligent slope analysis,multi-model integrated slope assessment,and intelligent slope monitoring and early warning platforms based on multi-source data fusion,are analyzed and organized.In response to current challenges in open-pit mine slope monitoring and early warning-such as insufficient multi-source information fusion capability,weak interactivity and simulation performance of 3D slope models with poor dynamic visualization,low generalizability of slope risk assessment and early warning models,and a lack of emergency response modules in monitoring platforms-this study outlines development trends for slope disaster safety management:accelerating the establishment of an intelligent sensing and monitoring system integrating multi-source data;enhancing slope risk assessment through digital intelligence to improve the accuracy of machine learning and enable real-time transparent analysis and feedback of slope information;and developing an intelligent disaster monitoring and early warning platform with holistic sensing,collaborative warning,and smart emergency response capabilities.
