Abstract:Through study on regional geology and mining area geology of Xiling gold deposit, geological data of the mining area has been collected and sorted out. After fully learning the technology of Vulcan software, geological drilling database of mining area has been set up for the first time, and several 3D Visual geological model and block models have been constructed. Resources have been estimated by using distance power inverse ratio method and ordinary kriging method, and the results have been compared with those of traditional geological block method.
