In order to quantitatively classify and evaluate the geological environmental risks in underground coal mine area,the main types of risks were identified during the research process,and based on this,the influencing factors of geological environmental risks were summarized,including natural geographical conditions,mining geological conditions,and engineering conditions.Further use the analytic hierarchy process to construct a three-level evaluation index system and assign quantified weight values to each level of indicators.Finally,based on the multi-criteria decision analysis model,the comprehensive evaluation index of the geological environment of the coal mine was calculated,and the risk level of the geological environment of the coal mine was determined based on the score of this index.Through actual testing,this method has achieved good application results.
