摘要：Because of the uncertainty of the influencing factors of coal mine fire in China, it will lead to the uncertainty of the evaluation results in the comprehensive evaluation of coal mine fire risk. Based on this, the goaf management, ventilation conditions, coal seam geological occurrence, and exploitation technology are used as first level evaluation indexes, and the fuzzy comprehensive evaluation method of fusion Dempster-Shafer evidence theory (D-S) is used to establish a comprehensive evaluation system for coal mine fire risk. The fire risk of Qiuji Coal Mine was comprehensively evaluated. The example shows that the fuzzy comprehensive evaluation method based on D-S can consider the uncertainty of influence factors more accurately and improve the accuracy and reliability of the comprehensive evaluation of coal mine fire risk. © Published under licence by IOP Publishing Ltd.
