Abstract
The invention discloses a kind of deposit three-dimensional Geological Modelings, the present invention is on the basis of modern metallogenic prognosis theoretical research, in conjunction with data such as existing terrain and geologic map, exploratory grid cross section, borehole datas, the terrain model, fracture model, stratum physical model, ore body model of diameter mouth mine section are established with three-dimensional geological modeling technology.The present invention can clearly express Orebody Grade value variation characteristic, and then deepen the understanding to the space distribution rule of ore body, mineral deposit.
Description
Technical field
The three-dimensional geological modeling method of present invention relates particularly to a kind of under three-dimensional visualization environment ore body.
Background technique
With earth's surface mineral products, the increasingly reduction of superficial part mineral resources, deep mine and buried ore be increasingly becoming every country and
Mainly reconnoitre object in area.It is existing that multiple Metals Deposit Ore areas progress resource is surveyed using multi-fractal mineral resource prediction theory
It looks into and evaluates, however as the continuous development of electronic computer and three-dimensional visualization technique, traditional analysis method has met
The not analysis demand of existing earth's surface mineral products.
Summary of the invention
For existing issue, the present invention is intended to provide a kind of deposit three-dimensional Geological Modeling.
For this purpose, the invention adopts the following technical scheme: deposit three-dimensional Geological Modeling, it is characterized in that including following step
It is rapid:
Step 1: analysis Geological environment of mining area constructs mine geology schematic diagram;
Step 2: establish geologic database: collect the drilling in mining area, exploratory grid cross section, exploratory trench, terrain and geologic map ground
Prime number evidence establishes perfect three-dimensional geological spatial database;
Step 3: programming is combined to complete three-dimensional geological modeling using Gocad software, three-dimensional geological modeling includes earth's surface mould
Type, FAULT MODEL, stratum physical model and ore body model;
The terrain model constructs digital terrain model using continuous coordinate points known to mining area are collected, and to model table
Face carries out correspondingly discrete smooth interpolation, improves digital terrain model more and close practical earth's surface;
The FAULT MODEL, which passes through, combines drilling catalog data and exploratory grid cross section to complete to tomography three-dimensional model
Building, drilling catalog data and exploratory grid cross section include length, thickness, the tendency, inclination angle that tomography extends in deep under ground,
The discrete point on a large amount of fault planes is combined processing using fault plane interpretation tool in Gocad software, obtains FAULT MODEL;
The stratum physical model is the layer data set of the stratal surface of multiple layered distributions, will be filled between two adjacent earth formations
Made ground plastid forms ground layer entity in area and forms stratum physical model;
The ore body model draws a circle to approve original referring to ore body profile by geological profile of exploratory line and drilling catalog data
Delineation then is carried out to ore body and forms ore body model;
The present invention can achieve following the utility model has the advantages that the present invention utilizes the visualization of nugget models coupling three-dimensional geological model
Function can express the grade value changing rule of ore body part, and then deepen recognizing to the space distribution rule of ore body, mineral deposit
Know.Three-dimensional geological modeling technology is used simultaneously, and high reliablity, effect of visualization is good, and traditional two-dimentional geology is extended to three-dimensional
Space carries out positioning and quantification, helps to analyze Mine area geologic structure feature and origin of ore deposit, is the one of modern searching mineral deposit
Kind effective means, this research can extend to other mines.
