Abstract

The invention belongs to the technical field of solid mineral exploration and three-dimensional geological modeling, and specifically relates to a method for extracting stratum boundary line to carryout three-dimensional modeling by utilizing exploration line profile. The method comprises the following steps: preparing and processing basic data, and carrying out translation, rotation and other operations on a profile to erect a two-dimensional profile map at the actual position of the three-dimensional space; extracting different geologic body boundaries on the section by utilizing the vertical geologic section; and establishing an integral three-dimensional geologic model by using the extracted geologic body boundary line according to the idea of breaking the whole into parts, carrying out block modeling and merging the whole parts. According to the method, the problem that the three-dimensional geology difficulty of a complex geology background research area is high is solved, the modeling precision is improved, the modeling effect is optimized, and technical support is provided for digitalization and quantification of mineral exploration.

Description

Technical field [0001] The invention belongs to the technical field of solid mineral exploration and three-dimensional geological modeling, and specifically relates to a method for extracting stratum boundary lines to carry out three-dimensional modeling by using an exploration line profile. Background technique [0002] In recent years, with the continuous development of science and technology, mineral exploration technology has also shown some new characteristics, among which the requirements for digitization and quantification are also increasing. The 3D modeling method has been recognized by the majority of geologists as a means to realize the digitalization and quantification of mineral exploration. At present, Australia, the United States, the United Kingdom, and Russia have formulated their own three-dimensional geological research plans around the world, and my country is also developing the corresponding three-dimensional quantitative prediction and evaluation methods of...
