Abstract: In order to study the characteristics of coal mine accidents in Inner Mongolia, and find the internal correlation and occurrence regularity of accidents, we use data of Inner Mongolia coal mine accident and death toll in 2011-2018 from Safety Monthly Report and Incident Investigation Report. Through them to get the characteristics and regularities of coal mine accidents in the whole region. The causes of accidents are further analyzed and countermeasures are put forward. Furthermore, we use model of multiple linear regression analysis to get the quantitative relationship between total number of accidents and different types of accidents. Hoping to provide a scientific basis for defining the trend of coal mine accidents in Inner Mongolia and formulating targeted accident prevention and control measures.
