Analysis and countermeasures of key risk factors of coal mine safety production based on SNA

We analyze the coal mine accidents since 2008, extract 30 causes of coal mine safety accidents, and construct the coal mine safety production risk factor network by using social network analysis（ＳＮＡ）. Through the point centrality analysis of SNA network, six key risk factors of coal mine safety production, such as inadequate management system, inadequate education and training, low staff quality, inadequate safety technical measures, less safety investment and inadequate safety supervision, are identified. Through the line centrality analysis of SNA network, six key influence paths of coal mine safety production risk are identified. Finally, according to the analysis results of risk key factors and risk influence paths, we put forward targeted suggestions to deal with the risk of coal mine safety production.
