Abstract: Lannigou Gold Mine is a typical Carlin-type gold deposit. The ore bodies are mainly hosted in fault fracture zones， and the surrounding rocks are mainly semi-hard and weak layered clastic rocks. The mine adopts the upward horizontal slicing and drift backfill mining method for production. By introducing international advanced working concepts and methods， using Access database and Surpac 3 D mining software as main tools， a complete database system and multiple practical 3 D DTM models， solid models and block models have been established， building a shared working platform for geological， surveying， mining and production management personnel. Based on the secondary development function library provided by Surpac 3 D mining software， a rich macro command system has been developed， widely used in drilling design， ore body interpretation and model building. This enables the mine to complete drilling design， geological logging， database management， ore body interpretation， production guidance， dilution and loss statistics， metal balance， data acquisition and other work with high efficiency and quality， promoting the intensive development and comprehensive utilization of mineral resources. By introducing the production geological working methods of Lannigou Gold Mine， it aims to provide new ideas and inspiration for geological workers in similar domestic mines.
