Abstract: A large number of geological exploration data of Bairong-Guangjiang Cu(Mo) mining area are collated and digitized based on DIMINE software.According to the characteristics of the ore-bodies and mineral veins of Bairong-Gangjiang Cu(Mo) mining area，the ore-bodies are delineated again and the formation model，rock mass model and ore-body model of Bairong-Gangjiang Cu(Mo) mine are established by the generated drilling database so as to realize the three-dimensional visualization of the geological data in the deep Bairong-Gangjiang Cu(Mo) mining area.The Cu and Mo grades are assigned by adopting the distance power inverse ratio method by checking and calculating repeatedly.Based on the assigned results，reserves estimation and statistics of the Bairong-Guangjiang Cu(Mo) mine are conducted.The research results show that the three-dimensional geological model of the Bairong-Gangjiang Cu(Mo) mining area established in this paper can reveal the metallogenic regularities and the underground space distribution characteristics of the geological bodies from the perspective of three-dimensional，and it provides convenience for estimating the reserves of mineral resources；the precision of reserve estimation is high by using the distance power inverse ratio method based on the three-dimensiol geological model of Bairong-Guangjiang Cu(Mo) deposit.Therefore，it has some reference for realizing the dynamic management of mine resources.
