【摘要】：三维地质建模是数字矿山的前沿领域,是矿山设计的重要基础,是实现矿山信息化的必要环节,对提高矿山的管理水平和经济效益具有重要意义。论文探讨了构建三维矿山模型的方法与应用,基于3DMine矿业工程软件,以依兰露天矿方正矿区的地质资料为基础,建立了地质数据库,并对空间插值技术进行了研究,利用粒子群算法对克里金球状模型的三个参数进行优化,利用钻孔数据对Kriging和PSO-Kriging算法误差进行交叉验证。实验结果表明,优化后的模型拟合度更高,将改进后的算法用在实体模型的建立和块体模型的估值当中,提高了建模精度,在建立的三维地质模型基础上,进行了境界优化研究,并确定了每年的采剥工程位置,为资源合理配量和生产系统优化提供科学依据。
[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.
