| 莫得东—格鲁图雷金矿床位于南非威特沃特斯兰德盆地东北部的东兰德金矿田内。为了深入研究该矿床地层、构造及岩浆岩和含矿层的空间分布，体现数字化矿山优势，利用空间分析技术对矿床地层、构造、含矿层实现三维可视化。本文通过收集并整理矿区原始钻孔数据资料，采用 3DMine矿业软件建立数据库、对含矿层特征进行分析和解释、构建矿体模型、建立块体模型并进行了资源量估算。估算该矿床保有(探明 +控制 +推断)资源量 6472769 t，金金属量 81039. 07 kg。结果表明该矿床具有较大的资源潜力，建立的三维模型为开展地质调查工程、采矿设计和矿山生产提供支撑，有助于剖析成矿特点、研究成因以及成矿预测，在实现数字化矿山建设方面也具有重要意义。 |

| The ModderEast-Grootvlei gold deposit is located in the East Rand Goldfield in the northeastern part of the Witwatersrand Basin，South Africa. In order to deeply study the strata，structure，magmatite and the spatial distribution of the ore-bearing layers，and to reflect the advantages of digital mines，the spatial analysis technology was used to realize the three-dimensional visualization of the strata，structures and ore-bearing layers of the deposit. This paper has analyzed and interpreted the characteristics of the ore-bearing layer，built the ore body model，established the block model and estimated the mineral resources，using the 3DMine mining software，bycollecting and organizing the original drillhole data and establishing a database. The results showed that this golddeposit has a retained ore resource(Measured + Indicated + Inferred)of 6，472，769 tons，and gold metal of 81，039. 07 kg. The results show that the deposit has great resource potential. The established three-dimensional model provides support for geological survey engineering，mining design and mine production scheduling，helps to analyze mineralization characteristics，deposit genesis study and metallogenic prediction，and is also of great significance in realizing digital mine construction. |
