Based on 264 borehole data of Danyin'gezhuang gold deposit,3D refined geological model of this mining area has been established,three dimensional spatial structures of gold deposits have been analyzed,and key ore-prospecting sections along the ore-controlling faults have been pointed out.As showed by 3D visualization analysis,main ore bodies of the study area scattersd in shallow areas are connected to the deep,and make up a super big gold deposit witn a gold resource of.more than 200t.The coupling relation-ship between the grade and thickness of main ore bodies and the structures characteristics show that the distribution of ore bodies are equally spaced,laterally and diagonally along strike and dip.The gold ore bodies are easy to be concentrated in the areas wtih large structure slope changes along dip.The coupling relationship between fault and gold deposit has been further clarified.It demonstrates the predictive role of 3D model in the deep exploration of gold deposit.
