Mineral resource and its exploration conditions are the primary sources of mining project investment risk.For the analysis of mining project investment risk,it is very important to make a rational evaluation on mineral resource and its exploration risk.In the paper,in view of the problem that it is difficult to make an objective,comprehensive and accurate evaluation on mineral resource and its exploration risk,a fuzzy synthetic evaluation method of mineral resource and its exploration conditions risk is put forward.Meanwhile,a risk evaluation index system of mineral resource and its exploration conditions is established,the multi-player structure of risk evaluation which is formed by 3 layers(target layer,criterion layer and index layer) is built up with analytic hierarchy process(AHP) method.The weights of each index are obtained after comparing them by each other,then the mathematic model of multi-level fuzzy synthetic evaluation on mineral resource and exploration conditions risk is established.
