Design And Implementation Of Ore Reserve Estimation And Ore Modeling System Based On Kriging Method

Reserve estimation of ore body based on Kriging method is an important research topic of geostatistics and plays a key role in mining engineering.The purpose of this system is to make full use of the sampling data in the exploration process to calculate the orebody reserves,and to use Kriging method to generate circle lines and orebody models.In this paper,the related theory of geostatistics is studied in depth,and the system requirements and main development technologies are analyzed in depth.Based on MVC development mode,Beego framework and Mongo DB database are adopted to realize system function and interface with front-end visualization technology such as HTML5,Web GL and Java Script.The system is mainly divided into three modules: ore reserves estimation module,automatic ore body delineation module and threedimensional visualization display module.In order to estimate the reserves of ore bodies,firstly,the data are processed and analyzed by statistical analysis;secondly,the geological space is deeply analyzed by the calculation of variation function,and the search ellipsoid is generated;secondly,the ore bodies are divided into blocks by octree structure,and the reserves of ore bodies are quickly estimated by parallel computing Kriging interpolation algorithm.In order to realize the function of automatic ore body delineation,this paper deeply studies the algorithm of automatic ore body boundary line generation,and constructs a three-dimensional ore body model.In this paper,the process of reserve estimation and ore body automatic delineation are displayed in threedimensional visualization mode;the positioning and orientation algorithm of ellipsoid in three-dimensional space is analyzed in depth,and the position of ellipsoid model in three-dimensional space is determined;the construction of quadripyramid,block model and ore body model by variance function search is realized.The system meets the needs of users,realizes the functions in the needs,and tries to be applied in actual mines.The system runs fast,the interface is friendly,stable and maintainable.It improves the working efficiency of geological workers and provides support for geological mining.
