摘要
菜园子矿床属于层间破碎(带)蚀变岩型岩金共生铜矿床,基于对该矿床的找矿需求,结合科学的成矿预测与理论指导,对菜园子矿床进行建模分析,利用SKUA-GOCAD软件对该矿区进行三维可视化研究,通过构建矿区的地表模型、地层模型以及三维实体模型,展现该矿床底部的地质构造。首先以等高线数据建立地表模型;然后利用钻孔资料、1:2000地质图等源数据建立地层模型,并建立该金矿床的地质网格模型,在此基础上建立矿床实体模型。结果表明,通过综合该研究区的多源数据资料,能够将勘查过程中产生的原始资料进行整理,将其整合到一个模型中,该模型展示了菜园子矿床的地表地下构造、矿床形状与地层接触关系,实现了对研究区不同地层的空间三维分布的展示,并且可以从模型中查看原始数据的准确性,为深部找矿工作提供依据,为矿区的进一步开发提供技术支撑。
Based on the prospecting demand of the deposit,combined with scientific metallogenic prediction and theoretical guidance,the Caiyuanzi deposit was modeled and analyzed,and the three-dimensional visualization study of the mining area was carried out by using SKUA-GOCAD software,and the geological structure at the bottom of the deposit was displayed by constructing the surface model,stratigraphic model and three-dimensional solid model of the mining area.Firstly,the surface model was established based on the contour data,and then the stratigraphic model was established by using the borehole data,1:2000 geological map and other source data,and the geological grid model of the gold deposit was established,and the physical model of the deposit was established on this basis.The results show that by synthesizing the multi-source data of the study area,the original data generated in the exploration process can be sorted out and integrated into a model,which shows the surface and underground structure,the shape of the deposit and the contact relationship between the strata of the Caiyuanzi deposit,and realizes the display of the spatial three-dimensional distribution of different strata in the study area,and can check the accuracy of the original data from the model,which provides a basis for deep prospecting and technical support for the further development of the mining area.
