Three-dimensional visualization modeling method for bearing/resisting stratum of coal measures

Abstract

The invention discloses a three-dimensional visualization modeling method for a water bearing / resisting stratum of coal measures, and the method comprises the steps: preparing the base materials of research; building a corresponding fault model according to a digitalized structural map and break point data; carrying out the dividing of the water-bearing stratum and the water-resisting stratum, recognizing a corresponding bearing / resisting stratum interface, building a bearing / resisting stratum stratigraphic framework, and building a corresponding stratum model through the Kriging interpolation method; carrying out the research of deposition geologic features of the stratum of the coal measures, and building a depositional microfacies model through combining sequential indication simulation with the sedimentary microfacies distribution features; taking the phase control technology and theory as the basis, and building a physical model of the water-bearing stratum according to the collected and calculated physical data; and displaying the spatial distribution rule of the bearing / resisting stratum of coal measures according to the finally built related model. According to the invention, the method carries out the objective description of the spatial distribution of the bearing / resisting stratum through modeling, visually reflects the three-dimensional spatial distribution of the bearing / resisting stratum and the water abundance features of the water-bearing stratum, and provides a three-dimensional visualization basis for the research of the bearing / resisting stratum.

Description

technical field [0001] The invention relates to a method for three-dimensional spatial distribution of a coal measure containing or water-resistant layer, in particular to a three-dimensional visualization modeling method for a coal measure containing or water-resistant layer. Background technique [0002] my country's coal production and consumption ranks among the top in the world, and coal plays a pivotal role in domestic energy consumption. With the increase of mine mining depth and intensity, mine water disasters occur more and more frequently. It is particularly important to find out the hydrogeological conditions of coal mines and study the distribution of aquifers intuitively. [0003] In the traditional study of coal-bearing or water-resisting strata, two-dimensional geological maps are mainly used, and the principles of projection geometry, descriptive geometry and ore body geometry are used to project the distribution of water-bearing or water-resisting strata on...

Problems solved by technology

[0006] However, the published technology still has the following flaws. First, the technology for discriminating sedimentary geological features by the public method is relatively simple, and the analysis is only based on the probability accumulation curve. The analysis results are not very accurate for the complex geological features. Second, the Markov principle of sedimentary microfacies modeling is a stochastic modeling method. The stochastic simulation method has great uncertainty, and only relying on mathematical calculations for sedimentary microfacies modeling cannot truly reflect the distribution of sedimentary microfacies

Third, the technical method used does not use structural modeling technology, which cannot reflect the control of structural features on coal-bearing or water-resisting layers
