Study on 3D Geological Modeling and Reserve Calculation of Goldsmiths Gold Deposit in Queensland in Australia
Three dimensional geological modeling is a key technology for"digital mining".Application of this technology for quantitative calculation of concealed ore bodies has become a hot topic in the field of mineral resources exploration.In this paper,by using multi—source data,a three—dimensional model has been constructed,and ore bodieds of Goldsmiths gold deposit in Queensland in Australia have been ana-lyzed comprehensively.Three—dimensional realistic display of the target gold deposit has been realized.Based on the principles of geostatistics,estimation of mineral resources has been completed,and its accu-racy with the traditional block method have been compared and analyzed.By using 3Dmine software,a 3D solid model,the scale,shape,and spatial distribution characteristics of the studied ore bodies have been visually displayed,and the grade,lithology,and other attribute information of the ore bodies at various spatial locations have been realistically reproduced.By comparing the calculation results with SD method and traditional block method,the feasibility of using the ore body entity model to calculate reserves has been reflected.It has profound significance for later mineral research work and mining design.
