Abstract: A new safety management mode for open-pit slope is proposed.In this mode，scientists of engineering sciences，field engineers and mining administrators are connected together to manage the open-pit slope according to information technology.Scientists of engineering sciences are mainly responsible for the potential risks searching，monitor scheme designing，slope stability evaluation and treatment plan of slope engineering determination.Field engineers are in charge of slope safety inspection，blasting hazards observation，slope monitoring equipment layout and various types of field data collection.Mining administrators preside over the organization and coordination，supervision and decision-making and emergency rescue.Based on such SEA management mode，a new concept for controlling open-pit slope is proposed，and the scientific connotation of this concept is introduced in detail.The new concept could be summarized as "monitoring headed，following probabilistic classification，status tracking，forecasting based on conditions，and disaster region simulating".SEA mode is practised preliminary in Anqian mine，According to the close and seamless cooperation among field engineers，scientists and mining administrators，the abilities about slope safety management，disaster early warning and scientific protection are enhanced.

Key words: Open-pit slope, Safety management, SEA mode, Monitoring, Blasting
