Research of subdivision algorithm of improved triangular prism

In view of problem of low precision and poor adaptive capacity of boundary conditions of existing calculation method for mine reserve, subdivision algorithm of improved triangular prism was proposed: triangular prism was divided into different cones according to different rules and combined with top surface, undersurface and triangle cut section of the improved triangular prism; reserve range was got according to border control conditions, and volumes and reserves of all improved triangular prisms within the control range were calculated combining with geostatistics.
