Abstract:

Sanshandao gold deposit(Cangshang gold deposit in Laizhou)buries shallowly and has a big ore—bodythickness，SO it is one of Chinag large—scale open—air gold mining．As no ores in the open—air mining field could be exploited basically，the mine was facing a resource crisis．To extend the life of Mine，we decided to study the law of mineralization and prospecting forecast of the deep of the mine and the ore—body footwal1．Analyzing，researching the No．3 structural alteration zone in the main and dominative structural alteration zone，based on ore—controlling structure characteristics and geological condition，we found that the prospecting drilling touched the gold ore．Than we exploited ore with construction silo in tunnel，we gained a industrial ore—body under the former ore—body with mining value．This discover protract the production life，at the same time．the open—air gold mining turned to underground mining l successfully．Our experience can be used to other similar deposit．

Key words: Mine resource, Structural ore—control, Proved reserve, Ore body characteristics
