Abstract: From views of the statistics information of 125 open-pit mines from The State Administration of Work Safety，the current situation of China's open-pit mine slope and the designed height distribution were analyzed.Above the height of 500 m slope is called the super high slope.The super high slope will be increased from 2% now to 14% in the future.According to the related suggestions at the national "Thirteen Five-year" planning，it is important and necessary to make analysis on the super high side slopes.With the super high slope disaster mechanism，safety control technology and online monitoring and early warning technology as the research subjects，and based on analysis of the related materials at home and abroad，the key influence factors of the slope disaster process，the slope disaster control process and the monitoring and early warning technology of current super high slopes from the aspects of the high stress and unloading effect，high damage，permeability and seepage characteristics，physical simulation and numerical simulation，the blasting safety control technology，large tonnage deep anchor reinforcement technology，online safety monitoring and intelligent warning technology are summarized.Combining with the characteristics of super high slopes，the problems and difficulties of current researches are pointed out，the development trend of super high slope is analyzed，and the challenge of the research is proposed.The challenge is including the joint water stress under the multi factor coupling catastrophe mechanism and failure mode; the high slope deformation mechanism of the large-scale simulation platform construction and numerical simulation technology; the micro blasting damage super high slope safety control technology; super high slope reinforcement technology of the Large Tonnage Pre-stressed Anchor deep; Super high slope landslide online safety monitoring and early warning technology.
