Outline
Based on the experiential knowledge of mine safety experts, a multi-level safety comprehensive evaluation index system and evaluation model for underground mines were established from 8 aspects, including the “three synchronizations” procedure for safety facilities, safety production organization guarantee, safety education and training, dual prevention mechanism, production system safety guarantee, hazardous materials and hazardous operation management, emergency management, and outsourced project management. The analytic hierarchy process (AHP) was adopted to calculate the weight of each index, and a safety comprehensive evaluation set was established to determine the comprehensive safety evaluation results of metal and non-metal mines. Practical application demonstrates that a certain underground metal mine in Hengyang has achieved a comprehensive safety evaluation score of 73.1, which is classified as “Medium”. Among the evaluation aspects, the mine has obtained relatively low scoring rates in hazardous materials and hazardous operation management, production system safety guarantee, as well as emergency management and outsourced project management. The established comprehensive safety evaluation results are basically consistent with the actual situation of the mine, and can effectively improve the scientificity and practicality of the safety comprehensive evaluation for underground metal and non-metal mines. The evaluation process not only helps enterprises identify weak links in safety production, but also provides a theoretical basis for further consolidating the safety foundation, strengthening safety management, and enhancing the safety level.
