Abstract: On the basis of the analysis of risk coupling characteristics of coal mine accidents, we classify the coal mine accidents coupling types in a reasonable way. According to the factors involved in the accident risk factors for coal, coal mine accidents will be divided into homogeneous risk coupling and heterogeneous risk coupling. For the different impact on the risks, the risk of coal mine accidents coupling is divided into the forward coupling, zero coupling and negative coupling. Based on the above risk classification, we make a further exploration on the mechanism of coal mine accident risk coupling. Finally, we propose effective countermeasures and suggestions for pre-controlled the occurrence of mines risk coupling from risk coupling process.
