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.
The geological database of deep deposit of fankou lead-zinc mine is constructed by using the three-dimensional software Surpac. The three-dimensional model of the surface, the three-dimensional solid model of deep ore body (below -320), the three-dimensional model of main fault and the three-dimensional model of roadway engineering are established Ore body block model; respectively, by ordinary Kriging and distance inverse method for the mineral element grade of the ore body were evaluated, the use of the valuation results were calculated by the metal elements and the middle of the reserves were calculated and calculated The result is contrasted with the result of actual exploration.The results show that the model and the grade and the result of the reserve are reliable, so that the underground body, such as deep ore body, rock formation, fault and shaft and so on, can be effectively realized Dimensional visualization and laid a solid foundation for the effective mining and exploration design and construction of deep deposits in mines.
