The invention provides a coal rock dynamic disaster multi-system multi-parameter integrated comprehensive early warning method and a coal rock dynamic disaster multi-system multi-parameter integratedcomprehensive early warning system. The coal rock dynamic disaster multi-system multi-parameter integrated comprehensive early warning method comprises the steps of: acquiring monitoring data of a plurality of coal rock dynamic disaster monitoring systems, and mining multivariate characteristic parameters, capable of reflecting precursor information of a coal rock dynamic disaster, in each monitoring system based on the monitoring data; screening out a characteristic parameter combination with the highest early warning effectiveness in each monitoring system and an optimal critical value of each characteristic parameter based on the multivariate characteristic parameters; calculating a comprehensive early warning index and early warning effectiveness of each monitoring system based on thecharacteristic parameter combination with the highest early warning effectiveness of each monitoring system and the optimal critical value of each characteristic parameter; and calculating to obtain acoal rock dynamic disaster multi-system comprehensive early warning result based on the comprehensive early warning index and the early warning effectiveness of each monitoring system. According to the coal rock dynamic disaster multi-system multi-parameter integrated comprehensive early warning method and the coal rock dynamic disaster multi-system multi-parameter integrated comprehensive earlywarning system, the advantages of the plurality of coal rock dynamic disaster monitoring systems are complementary, the early warning accuracy rate is improved, the influence of subjective factors iseliminated, and a certain guiding effect can be achieved for the development of mine disaster prevention and control.
