Study on Safety Management Assessment of Coal Mine Roofs Based on the DEMATEL-ANP Method

Coal mine roof accidents are one of the main single risks faced by coal miners. According to statistical data in China, there were 40 and 55 deaths 2020 alone, accounting for 32.8 24.4% total, respectively. Therefore, we can see its danger. To realize comprehensive scientific assessment accidents, first, through collation analysis relevant literature reviews accident investigation reports, combined with expert method, an index system is constructed. Then, based on characteristics influencing factors model established using DEMATEL-ANP method. Finally, applied a verify rationality model.
