Abstract

The present invention relates to a three-dimensional modeling method and device for a geological prospecting ore body, wherein the method includes: Step 1, delimiting a single project ore body according to the exploration project, and obtaining the upper and lower boundaries of the ore body; Step 2, projecting the prospecting project onto the prospecting project On the profile, connect the upper and lower boundaries of the ore body on the exploration profile to obtain the geological body boundary of the ore body in the exploration profile; step 3, connect the geological body boundaries between the exploration profiles with a three-dimensional curved surface to obtain the three-dimensional reconstructed geological body. The invention can realize geological three-dimensional modeling from drilling to profile to curved surface to finally generate solid.

Description

technical field [0001] The invention relates to the field of earth exploration and information technology, in particular to a three-dimensional modeling method and device for geological exploration ore bodies. Background technique [0002] In geological and mineral exploration work, a large number of problems involved are in three-dimensional space. Mineral exploration work is to obtain the basic information of minerals in three-dimensional space near the surface through exploration, pit exploration and other projects. The purpose is to find out the quality, Scale, location and shape. The key to a breakthrough in the prospecting of mineral resources in the periphery of the mine and deep in the mine lies in the realization of the three-dimensional positioning prediction of hidden deposits. The successful three-dimensional positioning prediction of hidden deposits depends on both new geological theories and exploration techniques and methods, as well as the use of advanced com...
