Three-dimensional modeling method for steeply-inclined thin-vein tungsten ore body

The invention relates to the technical field of three-dimensional modeling of ore bodies, in particular to a three-dimensional modeling method for a steeply inclined thin-vein tungsten ore body. The invention provides an automatic construction method of a steeply-inclined thin-vein tungsten ore body three-dimensional model developed based on an implicit modeling technology. The invention discloses a three-dimensional modeling method for a steeply inclined thin-vein tungsten ore body. The three-dimensional modeling method comprises the following steps: step 1, preprocessing drilling data; 2, mineralization section sample combination; 3, generating an ore body tendency boundary point; step 4, generating an ore body trend boundary point; 5, generating mineralized sample boundary points; and 6, generating an ore body three-dimensional model. According to the method, the boundary grade is set, the prior ore body boundary extrapolation rule is quantified, the ore body boundary points can be automatically generated
