Mineral resources reserves algorithm in digital mine framework

Reserves calculating is the important task of mineral resources reserves management which is an integral part of Digital Mine (DM). This paper selects the Analogic Tri-Prism (ATP) as basic volume unit to construct the spatial mineral model with the control points, and then puts forward two kinds of new reserves algorithms, ATP algorithm and regression algorithm. The results are as follows:the two methods not only could calculate mineral resources reserves accurately, but also could adjust the reserves dynamically according to the increasing information of the control points,and an instance is given to verify availability of the algorithms.
