三维建模与数字化管理在白牛厂银铅锌多金属矿区的应用

Application of 3D modeling and digital management in Bainiuchang silver-lead-zinc polymetallic mining area

白牛厂银铅锌多金属矿位于滇东南薄竹山花岗岩体北西倾没端,矿区从西到东由咪尾、穿心洞、白羊、对门山、阿尾五个矿段组成,银资源达超大型规模,锡、铅、锌资源达大型—超大型规模,同时伴生有丰富的分散元素(铟、镉、镓、锗等);随着地质产业数字化,矿山三维建模实现了地质资料数字化管理、三维可视化应用,笔者通过在矿区近4年的地质工作及以往资料综合整理,建立了地质数据库、三维矿体模型等,并将地表实景三维模型、地下采空区激光雷达扫描模型等多元数据进行配准融合,应用于矿山的信息化管理及深部找矿预测。

Bainiuchang silver-lead-zinc polymetallic deposit is located t the northwest dipping end of the Bozhushan granite body in Southeast Yunnan,.The mining area is divided into five ore sections from west to east,Miwei,Chuanxindong,Baiyang,Duimenshan,and Awei ore section.Silver resources have reached up to a superlarge scale,while tin,lead,and zinc resources have reached up to a large to superlarge scale,accompanied by abundant dispersed elements(indium,cadmium,gallium,germanium,etc.).With the digitization of the geological industry,3D modeling of the mine has achieved digital management of geological data and 3D visualization application.Through nearly 4 years of geological work in the mining area and comprehensive organization of previous data,the paper has established the geological database,3D orebody model.And multiple data such as surface real 3D models and underground goaf laser scanning models are registered and fused to apply to the information management of the mine and deep exploration prediction.
