The invention relates to a design method of a three-
dimensional simulation system for mining, which overcomes the defects that a three-
dimensional simulation technology is low in quality, precision and intelligent mapping degree in the mining process. The design method comprises the following steps of: manufacturing an
earth surface entity by a topographic mapping method using a rotary
mating TIN (
Triangulated Irregular Network) and distance and included angle biweight interpolation method; manufacturing a geological map of a surveying area by a geological surveying method of directly manufacturing a geological surveying result plan and an elevation by a
disclination maneuvering network non-section method; synthesizing a three-dimensional visual model of mining geology; performing stripping design on a strip mine, or design on shaft building, advancement and exploitation of an underground mine, obtaining the position and direction of an intersecting line of two flats of broken mines (rocks) at a fault according to original geological data in shaft building, excavation or stripping, and adding the position and direction to the three-dimensional visual dynamic model, a sinking and driving
engineering layout plan and a mine (rock) stratum (body) seam floor contour (isopach) map for mining geology and exploitation
engineering; and establishing a mining geology and exploitation management module.
