Based on the general investigation and field investigation of the current situation of the level of economical and intensive utilization of mineral resources in the underground mining mines in Zhejiang Province, analyzes the technical, economic, management and other indicators affecting the level of economical and intensive utilization of mineral resources, and calculates the standard value of the indicators in combination with the mine investigation data. Analytic hierarchy process（AHP） and expert scoring are used to establish the weight of evaluation index items and the evaluation index system of the level of economical and intensive utilization of underground mining. Through the index weight and the current objective score of the mine in the index system, the overall evaluation score reflecting the level of economical and intensive utilization is obtained to measure the level of economical and intensive utilization of the mine, that is, the higher the evaluation score, the stronger the level of economical and intensive utilization of the mine. In order to further verify the rationality, applicability and fit degree of the evaluation index system, 39 typical underground mining mines in Zhejiang Province are evaluated on the level of economical and intensive utilization of underground mining mineral resources. The results show that the evaluation value is basically consistent with the actual situation of the development and utilization of mining enterprises, which can objectively reflect the level of resource conservation and intensive utilization of mining enterprises, and provide ideas and decision-making suggestions for the establishment of the assessment and supervision mechanism of the level of mineral resource conservation and intensive utilization of the whole province.
