Abstract: Deposit geology dimensional graphical representation method can express the complex geological structure, the deposit geology in three-dimensional morphology forms, can be effectively applied to mineral exploration oil and gas exploration, coal geological exploration, mine production and management, geological disasters governance and other geological sciences fields. Using a Copper-molybdenum mine as an example, a research work is presented for a three-dimensional graphical representation method of deposit geology. Build a three-dimensional geological model, exhibit geological characteristics of the deposit with multi-angle, multi-level.
