A method and system for three-dimensional geological modeling of ore concentration area scale

Abstract

The invention discloses an ore concentration area scale area three-dimensional geological modeling method and system. The method comprises a step of obtaining geological survey data which comprises stratigraphic area feature data, tectonic line feature data, occurrence point feature data, drill hole feature data, exploration line feature data, and trenching feature and tunnel feature data, a step of defining the spatial and temporal relationship between stratums, the spatial and temporal relationship between faults, and the spatial and temporal relationship between the stratums and the faults, a step of using a Cokriging algorithm to carry out implicit spatial interpolation on the geological survey data and the spatial and temporal relationships, a step of constructing a virtual geological section according to an interpolation result, a step of editing the virtual geological section, and a step of determining an ore concentration area three-dimensional geological model according to the virtual geological section. The invention provides the ore concentration area scale area three-dimensional geological modeling method and system, and on the basis of ensuring low cost, the accurate modeling of the geology of an ore concentration area scale area can be carried out.

Description

technical field [0001] The invention relates to the field of three-dimensional geological modeling, in particular to a method and system for three-dimensional geological modeling of ore concentration area-scale regions. Background technique [0002] Since the beginning of the 21st century, the international demand for mineral products has been strong, prices have continued to rise, exploration investment has hit new highs, and the mining industry has developed rapidly. Domestically, the sustained, rapid and healthy development of China's economy has stimulated the rapid growth of demand for energy and mineral raw materials, which has attracted worldwide attention. China's mining and geological work is generally in step with global development. The mining and geological work has come out of the trough, the geological prospecting economy is developing rapidly, and the profit of the mining industry is growing rapidly; geological prospecting is highly valued, the main body of e...

Problems solved by technology

[0006] However, at present, the geological model for the scale area of ​​the ore concentration area is blank, and because the area of ​​the scale area of ​​the ore concentration area is much larger than the area of ​​the mining area, this makes the modeling method applied to the resource exploration of the mining area no longer applicable In the area of ​​ore concentration area, for example, we need to drill multiple boreholes in the mining area to assist the establishment of geological models, while in the area of ​​ore concentration area, the number of drill holes is relatively large due to the large area of ​​the ore concentration area. There are many more than mining areas, and the cost will increase sharply. It can be seen that the traditional modeling method to model the regional geology of the ore concentration area is not ideal and realistic
