Study On Establishment And Application Of Three-dimensional Geology Model In Yilan Open Pit

The three-dimensional geology model is the forward field of digital mine and it is the important basis for mine design and the necessary link to realize the mine information. It is significant to improve the manage level and economic benefit of mine.This paper discusses the method and application to construct the three-dimensional geology model, based on the 3DMine mine engineering software and the geology data of Fangzheng mine area in Yilan open pit to construct the geological database. It studies the spatial interpolation technology and simulates the three parameters of Kriging spherical model by particle swarm optimization, and cross verifies the errors of Kriging and PSO-Kriging algorithm by drill data. the results indicate that the fitting degree of simulated model is higher, and taking the improved algorithm to the building of entity model and valuation process of block model, it also improve the simulating degree. On the basis of building the three-dimensional geology model, studies the boundary optimization and determine the position of mining and stripping engineering every year, and provide basis to resource reasonable proportioning and production system simulation.
