Based on the geological study of the Ashele copperzinc deposit, the writers studied the three\|dimensional model of geology. This paper principally probes into the possibility of achieving three\|dimensional visualization of the geological model in the computer. According to the geological engineering data of this area, the VULCAN software system, which is an excellent software on three\|dimensional visualization, has been used to construct the three\|dimensional model of the drill holes. Then, based on the drill holes model, the mineral three\|dimensional model is constructed depending on the spatial location of the mine, and the three\|dimensional geological model, and the reserves can also be estimated . The construction of the three\|dimensional visual model is important in understanding the deep geology and mining
