Abstract: The goal for comprehensive evaluation of mineral resources is to obtain the information of mineral exploration and the degree of resources security in the evaluation area so as to provide basis for the following work such as improving development efficiency，optimizing the structure of mineral development，conducting evaluation of mine environmental protection and governance.Taking the middle area of Tibet as the research example，the nine advantageous resources such as polymetallic ore，copper ore，molybdenum core，chromite ore are selected as the mine object of evaluation.The 33 geological exploration evaluation units are divided based on analyzing the existing two mineral resources planning of Tibet autonomous region.The evaluation index system for geology exploration of mineral resources is established by considering the four kinds of factors such as degree of work，physical effort，resources and quality characteristics and exploration technology synthetically.The weight values of evaluation index are calculated by using the analytic hierarchy process (AHP) and expert scoring method.The fuzzy comprehensive evaluation is conducted by using the fuzzy comprehensive evaluation model based on grey correlation degree so as to provide some reference for the new mineral resources planning in this research area.

Key words: Evaluation of geological exploration, Mineral resources planning, Analytic hierarchy process, Grey correlation degree, Fuzzy comprehensive evaluation model
