The invention discloses a method for evaluating the comprehensive environmental pollution risk of a waste mining area, and the method comprises the following steps: 1, analyzing indexes which affect the pollution risk of a waste mine cave, a waste rock heap and a waste ore spot to the environment, and screening out key indexes; 2, calculating the weight of each key index in the step 1 according to an analytic hierarchy process; 4, according to the results of the step 2 and the step 3, the comprehensive score of the target abandoned mine cavern, the waste rock heap and the abandoned ore spot is calculated, the higher the score is, the higher the risk level is, and the smaller the score is, the lower the risk level is. According to the invention, limited resources are fully utilized to carry out comprehensive treatment or risk management and control on existing environmental risks. And technologies such as reinforced plugging can be adopted for medium-high-risk ore caves, a simple plugging technology can be ado
