    • Abstract
  • One of the core tasks of digital mine is to build an integrated real three-dimensional model of the mine. The difficulty of the task is to set up a precise and complete three-dimensional geological model, namely underground ore-body modeling and reserve estimation. In order to establish three-dimensional model quickly, design mining and find out deposit reserves based on the model, a three-dimensional ore-body modeling and reserve estimation approach based on 3DMine software was proposed. Firstly, geological database and three-dimensional surface/ore-body model were established according to the existing geological information and drilling data. Secondly, the ore-body model was divided into the discrete block combination model, and the inverse distance weighted method was used to estimate mine resources reserves. The results show that the software can easily build real three-dimensional model, which will reflect the ore body shape , size and the spatial correlation of ore body and reserves blocks intuitively. It can also provide a platform for the mine designing and planning. Besides, compared with traditional geological block method, the inverse distance weighted method based on an unbiased estimate of the sample points is easier to achieve in software with more reliable result.
