Abstract: The paper proposed an opinion of constructing mathematics models which accords with characters of Marcov chain according to characteristics of coal mine, and used Marcov chain as a basic analyzing tool to describe mathematics modeling methods in three fields including fault analysis of electromechanical equipments, early warning analysis of underground waterbursting, and forecasting analysis of emergency rescue in details. The constructed models can predict probability of equipment faults, probability of underground waterbursting and escape situation after emergency, which provides probable data for coal mine disaster predicting and theory support for technology realization of coal mine disaster predicting system.
