[Abstract]:Three-dimensional geological modeling is the frontier field of digital mine, the important foundation of mine design, the necessary link of realizing mine informatization, and it is of great significance to improve the management level and economic benefit of mine. This paper discusses the method and application of constructing 3D mine model. Based on the 3DMine mining engineering software, based on the geological data of Yilan open-pit mine, the geological database is established, and the spatial interpolation technique is studied. The particle swarm optimization algorithm is used to optimize the three parameters of Kriging spherical model, and the error of Kriging and PSO-Kriging algorithm is cross-verified by drilling data. The experimental results show that the optimized model has higher fitting degree, and the improved algorithm is used in the establishment of solid model and the estimation of block model, which improves the precision of modeling, and on the basis of the established 3D geological model, the improved algorithm is applied to the establishment of the solid model and the estimation of the block model. The boundary optimization is studied and the location of the annual mining and stripping project is determined, which provides a scientific basis for the rational allocation of resources and the optimization of production system.
