Similarity judgment-based local anisotropy search ellipsoid model simplification method

Abstract

According to the similarity judgment-based local anisotropic search ellipsoid model simplification method provided by the invention, regular grid division is performed on an ore body in a research area, a local search ellipsoid model is generated at the position of each unit block body of a regular grid, and then simplification parameters and a search window are set; acquiring spatial orientations of adjacent ellipsoids in the search window, calculating similarity of the spatial orientations, judging, moving the search window to traverse all positions of the current ore body model, expanding the search window until no search ellipsoid model capable of being merged exists in the search window under a certain scale, and finally, searching for the current ore body model. According to the method, the problem that huge data is difficult to manage due to the fact that a large number of dynamic search ellipsoids appear in a research area can be solved, and the data of the dynamic search ellipsoids can be reasonably and efficiently organized and managed, so that the problems that the data size is huge and management is difficult are solved in the whole reserve estimation process.

Description

technical field [0001] The invention relates to the technical field of geostatistical mineral resource reserve estimation, in particular to a method for simplifying a local anisotropy search ellipsoid model based on similarity judgment. Background technique [0002] Mineral resource reserves are the general term for mineral resource reserves obtained through mineral resource exploration and feasibility evaluation. An important part of the work, it is the process of calculating and determining the quantity, quality, spatial distribution, mining technical conditions and research accuracy of mineral resources by using certain methods based on the relevant information and data obtained in each exploration stage. Reserve estimation runs through the entire life cycle of a mine. Mineral resource reserve estimation is a comprehensive assessment and summary of the "quality" and "quantity" of mineral resources, and is the main basis for production construction and enterprise investmen...

Problems solved by technology

[0004] The local search ellipsoid model exists in the regular grid in the internal space of the ore body, and its spatial orientation corresponds to the anisotropy characteristics of the ore grade. However, this way of managing the local search ellipsoid with a regular grid faces a The problem of low data storage efficiency, when encountering complex shapes and large volumes of ore bodies, a large number of local search ellipsoids will appear in the research area, it is difficult to obtain satisfactory performance in this way, so the present invention proposes Simplification method of local anisotropy search ellipsoid model based on similarity judgment to solve existing problems in prior art
