摘要
The polygonal method is a conventional technique that is widely used for mineral reserve estimation abroad, like the sectional method in China. The polygonal method is simple, easy to understand and use, thus very acceptable to exploration geologists around the world. This method estimates mineral reserves within a polygon which is created by an exploration project located in the center of a circle with an influent radius. The estimation is independent of other projects so that the procedure is simplified. No matter there is only one or many exploration projects, reserve estimation can be carried out smoothly. The polygon blocks are created automatically, and therefore the reserve estimation no longer depends on the complicated exploration lines and sections which are drawn manually. Besides, this method is more objective. The reserve or resource categories can be classified easily by the influent radius determined.
