Abstract: It is the basic requirement of mining production to furthest improve ore recovery and reduce the dilution rate are, especially for the noble metals such as gold, silver.Qinghai Shanjin Gold Mining Industry Co., Ltd.fishes out a route of fine mining in long-term gold mining production, and applied it into practice.Under the engineering background of Guoluolongwa area of Gouli Gold Mine in Qinghai, the implementation method and process of fine mining are introduced in detail, including the fine geological investigation, fine measurement, fine modeling, scheme optimization, fine construction and so on.Good results have been obtained since its implement.

Key words: Fine measurement, Fine modeling, Scheme optimization, Fine construction
