云南羊拉铜矿三维地质建模及储量计算

3D geological modeling and reserves estimation in Yangla Copper Deposit in Yunnan

以云南羊拉铜矿的断层、地层、岩体、矿体为研究对象,在分析研究建模技术方案的基础上,依据收集到的钻孔柱状图、勘探线剖面图、中段地质图和地形地质图,结合野外踏勘与认识,利用Micromine软件建立了研究区的地形、地层、断层以及矿体的三维实体模型,直观展示了区内地表、断层、地层、岩体以及矿体的空间展布以及相互的空间位置关系。运用克里格法对里农矿段的铜矿体进行品位估值,获得了矿体的储量。

Taking the fault, strata, rock mass and ore body in Yangla Copper Deposit as study targets, based on the analysis and study modeling technology plan, the available of borehole histogram, prospecting line profile, middle geological map and topographic geologic maps and in combination with field exploration and knowledge, the authors established a 3D solid model on landform, strata, fault and ore body in the study area by the use of Micromine software, directly exhibited the spatial distribution and mutual spatial locations for the surface, faults, strata, rock mass and ore body in the ore district. The authors estimated the grade of Linong ore section with Kriging method and acquired the reserve of the ore body.
