Abstract：Aimed at the complexity and variability of the ventilation system in the production process of coal mines, an extension evaluation method based on matter-element theory was introduced in the safety evaluation of the mine ventilation system. In this paper, the indicators related to the safety evaluation of the mine ventilation system were determined according to the relevant provisions and the actual situation, and in the process of the extension evaluation, the information entropy theory was used to objectively and accurately evaluate the weights of the evaluation indicators, analysis was made on the evaluation indicators by taking Jinda Mine as an example, the evaluation results were verified according to the actual situation of the mine, and the rationality of the evaluation results was determined.
