矿山三维实体建模

采用大型矿床三维软件Surpac构建了凡口铅锌矿深部矿床地质数据库,建立起了该矿的地表三维模型、深部矿体(-320以下)三维实体模型、主要断层三维模型、巷道工程三维模型以及矿体块体模型;分别采用普通克立格法和距离反比法对矿体金属元素品位进行了估值,运用估值结果分别按各金属元素和各中段进行了储量的统计计算,并将计算结果与矿山实际勘探获得的储量结果进行了对比分析.实践表明,所建模型和品位、储量计算结果可靠,从而有效地实现了该矿山深部矿体、岩层、断层、井巷工程等地下空间体的三维可视化,并为矿山深部矿床的有效开采和勘探设计及施工奠定了坚实的基础.

Mine 3D Solid Modeling

The large 3D deposit software Surpac was used to construct Fankuo Lead-Zinc Mine deep deposit geological database,strike up the earth's surface 3D model,deep body 3D model(under-320m),main faultage 3D model,laneways project 3D model and the block model of the mine body;ordinary Kriging and distance inverse ratio method was taken to estimate the elements grade,which conclusion was applied to calculate the reserves of each sublevel,and then compare it with the actual reconnoiter result.It shows that the established model is reliable and the results are correct.They can be used to assistant the geologic and mining engineers to do their works of reserve estimation,mine design,planning and so on.Realizing the 3D Visualization of the deep mine body,terrane,faultage,laneways project and so on effectively,settled the basis of the efficient deep exploitation,reconnoitre design and construction.
