Abstract: There are some uncertainties such as economy， market， resource endowment condition， enterprise control ability and national policies when making decisions on mining resources acquisition for decision makers of mining enterprises. It maybe delay the best time for resource endowment when decision makers rely more on the traditional method of judging and making decisions through feedback of technical and economic indicators after design is completed. It is considered that among the uncertainties affect decision-making and judgment， only the ability of control and resource endowment condition can be controlled and selected by enterprises， while other factors cannot be controlled， and the resource endowment condition is the main factor to judge the success or failure of the project when the enterprise management and control ability is constant based on the practical experience in resource development. The fast and convenient judgment model is constructed by the grey theory on account of the five key elements of resource endowment conditions such as size of reserves and depth of burial， ore grade， the size of deposit's water inflow， ore， rock stability and ore milling performance， were used as evaluation indexes. It provides an effective decision-making basis for enterprise decision makers.
