specific Embodiment 1

[0123] The application of the 3D modeling method for the fault structure of a gold mine, the specific implementation framework is as follows Figure 8 Shown:

[0124] Collect, process and store fault data in mining areas through fault data acquisition equipment. Fault data acquisition equipment includes traditional survey, electronic survey, geological drilling, seismic detection, geological radar, total station, GPS survey and digital scanner. Use Oracle database, GIS and other tools to digitize the original data, and store, manage, maintain and process information.

[0125] The structural form of the mine is dominated by faults, these faults are tension-torsion or compression-torsion faults, with a dip angle of 35° to 80°, a dip of 180° to 220°, and a drop of 3 to 30 meters (Table 5). Integrate boreholes, 2D / 3D profiles, structural geological maps, and fault attributes into the system, extract fault control points from them, and interpret them to form Class I and Class II ...

specific Embodiment 2

[0130] Application of 3D modeling method of fault structure in a coal mine.

[0131] Step 101: Collect, process and store fault data in the mining area through fault data acquisition equipment.

[0132] Step 102: This area is an area with extremely active tectonic activities, and the geological structure is mainly based on faults. Faults are relatively developed in the mining area, and more than 40 large and small faults have been exposed. The northwest wing of the syncline mostly develops strike compressive reverse faults, while the southeastern wing is dominated by high-angle dipping or oblique normal faults of extensional and torsional nature; the fault strikes are divided into two groups: northeast and northwest. Faults with drop greater than 50m are mainly distributed at the southern end of the southeast wing. Integrate borehole (Fig. 9(a)), 2D / 3D profile (Fig. 9(b)), structural geological map (Fig. 9(c)), and fault attributes (Table 6) into the system, and extract faul...

Abstract

The invention discloses a fault structure three-dimensional modeling method. The method comprises the steps that fault data are integrated in a three-dimensional visualization system; fault control points are extracted and a fault line is explained and formed; connection analysis of multiple conditions and fault line and fault attribute revision are carried out; the relationship between faults is calculated, and a fault network which reflects the topology structure is established; intersection is carried out on fault faces and a constructed initial stratum model to acquire an initial intersection line of the stratum and the faults; fault distance calculation is carried out on each fault point on the initial intersection line, and a three-dimensional fault line with upper and lower walls is acquired; weight setting is carried out on produced fault data of various kinds, and then fault face fitting is carried out to form a fault face network; and stratum model construction is carried out. Data detection can be effectively carried out. The accuracy of a fault model is ensured. The fault structure three-dimensional modeling method can be applied to petroleum, geology and other fields.

Description

technical field [0001] The invention relates to a three-dimensional geological modeling technology, in particular to a three-dimensional modeling method for fault structures. Background technique [0002] 3D geological modeling plays an important role in the understanding of geological exploration and the analysis of geological evolution process. The establishment of 3D geological model is an important means in the field of earth science, involving the evaluation of natural resources, disaster simulation and prediction, etc. Since faults cut rock units and play an important role in subsurface natural phenomena, the construction of fault structures is a crucial step in 3D geological modeling. [0003] At home and abroad, some design methods for establishing fault models and the process of grid-based 3D structural modeling have been proposed. However, in structural geology, natural phenomena such as faults and faults increase the complexity of the subsurface geological struct...
