Abstract: Open-pit mines in alpine regions are facing harsh natural environments such as extreme low temperatures,se vere temperature differences,drought and hypoxia,and strong winds and less rain,making mining face enormous challenges. Based on the CiteSpace bibliometric analysis method,the development context and research hotspots of open-pit mine technolo gy in alpine regions in recent years are sorted out.The research results show that the existing achievements mainly focus on the application of intelligent equipment,the influence mechanism of freeze-thaw cycle,slope stability analysis and ecological envi ronment restoration,but there are some problems such as low system integration,insufficient dynamic response ability and scat tered technical paths.At present,the research cooperation relationship in this field mainly presents locality and regionality,and the cooperation between academia and business community is still insufficient.The research hotspots of high-cold open-pit mines are freeze-thaw cycles and slope safety.The future research trends are the influence of freeze-thaw cycles on the micro structure of rock mass,intelligent monitoring and stability optimization of slopes in cold regions.Finally,in view of the above shortcomings,the development suggestions are put forward:it is necessary to construct an intelligent collaborative operation sys tem adapted to the alpine environment,develop a slope instability prediction model integrating multi-factor disturbance mecha nism in the alpine region,establish a zoning and classification ecological restoration technology system,and introduce a whole process evaluation mechanism to improve the quantitative control ability of the restoration effect.
