Study on coordination of coal mine emergency rescue system

A coordination model of coal mine emergency rescue system was established by use of social network theory based on analysis of coordination features of coal mine emergency rescue system, and coordination status was acquired by calculating point centrality, network density, unit coordination entropy and system coordination entropy. The application results show that quantitative analysis and evaluation of coordination status of coal mine emergency rescue system can be realized with application of social network analysis method in coal mine emergency rescue system, which has guiding significance for promoting efficiency of coal mine emergency rescue system.
