Abstract: In order to realize the digital intelligent management of emergency preplans and quickly generate accurate and effective rescue plans, the web crawler technology was used to obtain basic data from accident cases and post-incident situations, and the data was structured and processed.Constructing a hierarchical and structured emergency preplan generation model, combining fuzzy comprehensive evaluation method and analytic hierarchy process to evaluate the effectiveness of emergency preplans, forming a digital intelligent emergency preplan system for coal mine accidents.Selecting coal mine gas explosion accidents, verifying the sub event sets of "August 29" Xiaojiawan Coal Mine gas explosion accident and "October 31" Jinshangou Coal Industry gas explosion accident, proving that the results of intelligent emergency plan generation were basically consistent with the actual situation.The research results indicate that real-time addition of incident information, rapid generation of visual contingency plans, automatic analysis of structured storage can improve the generation efficiency and accuracy, reduce the accident disaster risks and losses, and improve the ability of mine emergency rescue support.
