Abstract: The operation of underground mines is dangerous and the spatial topology is complex,so mine safety accidents often occur. Reasonable emergency evacuation path planning and evacuation instructions can effectively improve the escape efficiency of underground personnel and reduce casualties and property losses. Combined with an example of an underground mine,an underground mine roadway network model is built based on space syntax and GIS network analysis. From the perspective of spatial cognition of escape personnel,the foreground network and background network in the roadway network model are selected as the main avoidance points by using the standardized angle choice degree. It provides a reference for the layout of emergency evacuation indicators. Considering the basic roadway attribute information such as roadway width,roadway type and roadway slope,and combined with the space syntax index (standardized angle integration degree),an emergency vulnerability model of roadway network is constructed. Considering the stability of roadway spatial units,the optimal cognitive path of underground personnel is planned,and multi-objective emergency evacuation route planning of underground mine is realized. This research can not only provide suggestions for the design of tunnel layout in underground mines,but also assist decision-making for emergency evacuation path planning in underground mines,provide theoretical basis for the formulation of emergency plans,and provide new ideas for the construction of emergency hedging systems.
