Abstract To study the space fault network theory and the area risk of open-pit mining area, the theory and method of space fault network are applied to the study of the disaster evolution process in open-pit mining area. The open-pit mine is close to a city and has complex hydrogeological conditions. The characteristics of disasters occurring in different areas are quite different, which lead to the diversity of the disaster evolution processes. It makes disaster analysis, prevention and management more difficult. Space fault network is a theory to study the evolution process of system faults. The evolution process can be studied from the perspective of macro-evolution process and micro-event relationship. The area characteristics of the open-pit mining area are studied and the area division is carried out. Based on the existing data, the space fault networks of disaster evolution processes in different areas are established. Space fault network is transformed into space fault tree, and disaster evolution models in different areas are simplified. Three indicators, structure importance, structure complexity and structure accessibility, are proposed to measure the possibility that the edge event will lead to the target event. The characteristics and relationships of these indicators are described. Finally, taking the evolution process of south wall disaster as an example, the above three indicators are calculated, and the edge events are sorted and the significance of sort is explained. This is the beginning of the application of space fault network to the study of disaster evolution process of open-pit mine.
