烂泥沟金矿生产地质国际化技术管理体系

International technical management system of production geology in Lannigou Gold Mine

烂泥沟金矿属于典型的卡林型金矿,矿体主要赋存于断裂破碎带中,围岩以半坚硬软弱层状碎屑岩类为主。烂泥沟金矿选用上向分层进路胶结充填采矿法进行生产采矿,并引入国际先进工作理念和方法,以Access数据库和Surpac三维矿业软件为主要工具,建立了完整的数据库体系和多个实用三维DTM模型、实体模型及块体模型,搭建地质、测量、采矿及生产管理人员共享共用的工作平台;基于Surpac三维矿业软件提供的二次开发函数库,开发了丰富的宏命令体系,广泛应用于钻孔设计、矿体解译和模型建立等工作。使得矿山在钻孔设计、地质编录、数据库管理、矿体解译、生产指导、贫化损失统计、金属平衡、数据获取等工作均能高效率、高质量完成,促进了矿产资源的集约开发与综合利用。通过介绍烂泥沟金矿生产地质工作方法,以期为国内同类型矿山地质工作人员提供新思路和启发。

Lannigou Gold Deposit is a typical Carlin-type gold deposit.The ore body mainly exists in the fracture zone,and the surrounding rock is mainly semi-hard soft bedded clastic rock.Lannigou Gold Mine chooses the upward slicing cemented filling mining method for production and mining.With the introduction of advanced international working concepts and methods,and Access database and Surpac 3D mining software used as the main tools,a complete database system and a number of practical 3D DTM models,entity models and block models are established,and a shared working platform for geological work,surveying,mining and production managers;based on the secondary development function library provided by Surpac software,a rich macro command system is developed,and widely used in drilling design,ore body interpretation,and model building.The work of drilling design,geological logging,database management,ore body interpretation,production guidance,loss and dilution statistics,metal balance,and data acquisition can be completed with high efficiency and high quality and promotes the intensive development and comprehensive utilization of mineral resources.This paper introduces the geological working method of production in Lannigou Gold Mine,in the hope that it can provide a new idea and inspiration for the geological team of similar mines in China.
