Abstract: 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.
