Specifically, as shown in Figure 1, the method for determining the target geological body in the three-dimensional geological modeling of the mining area includes the following steps:

Step S100, obtaining geological and mineral data of the mining area, and performing preliminary division of geological bodies in the mining area according to the geological and mineral data, to obtain preliminary divided geological bodies.

During specific implementation, the present embodiment first collects geological and mineral data of the working area (i.e. the mining area), and the geological and mineral data includes but not limited to geological reports, geological maps, structural outline maps, ore field geological maps, and deposit exploration reports. Then, according to the geological and mineral data, the geological distribution and occurrence extension characteristics of each geological body in the mining area are determined, and the geological distribution and occurrence extension characteristics include: mining strata, formation age of magmatic rocks, and upper-lower superposition relationship And mutual cutting, intrusion relationship, etc. Specifically, in this embodiment, on the basis of the geological and mineral data, the actual geological profile measurement of the mining area is carried out to sort out various geological bodies (including stratigraphic groups, magmatic rocks, fracture structures, and rock ore bodies), and determine the surface filling. In the map unit, carry out detailed surface geological surveys, fill in the geological map of the modeling area, clarify the geological distribution and occurrence extension characteristics of surface geological bodies, and clarify the lithological composition and thickness of each geological body to obtain the description.

According to the stratum in the mining area, the formation age of magmatic rocks, the relationship between upper and lower superimpositions, and the relationship of mutual cutting and intrusion, the geological bodies in the mining area are preliminarily divided, and the preliminary division table of geological bodies is obtained, as shown in Table 1.

Table 1 Preliminary division of target geological bodies in 3D geological survey of a mining area

It can be seen from Table 1 that the primary geological bodies included in the preliminary division table include: Hejia Formation, granite porphyry, the second member of Tianjia Formation, the first member of Tianjia Formation, the second member of Chenjia Formation, and the first member of Chenjia Formation , Dashan rock mass, Qingbaikou system metamorphic rock, fault fracture zone, ore body and mineralized alteration zone. And the lithological composition, thickness and formation age of these preliminary divided geological bodies are included in the preliminary division table.

Step S200, obtaining the physical property parameters corresponding to the physical property measurement samples of the preliminary divided geological bodies, and performing statistical analysis on the physical property parameters to determine the difference and distinguishability of the physical property parameters between the preliminary divided geological bodies .

Specifically, in this embodiment, the physical property measurement samples of the primary geological body in the mining area are collected, and the number of physical property measurement samples of each rock (stratum) is greater than 10, and the samples are as fresh as possible. Then measure the physical property measurement sample to obtain the physical property parameters. The physical property parameters include: density, magnetic susceptibility, resistivity, and wave velocity. , Magnetic susceptibility meter, direct current method instrument, ultrasonic instrument for measurement. Finally, the physical parameters of the samples are counted. If there is a large difference in the physical properties, the reason should be analyzed, and whether to collect additional samples should be considered, and then the physical properties should be measured. According to the statistical characteristics of the physical parameters of the samples, the differences and distinguishability of the physical parameters between each preliminary divided geology are analyzed.

For example, when determining the target geological body in the 3D geological modeling of a certain mining area, the physical property measurement samples of the geological body that were initially divided were collected, and the physical property measurement and statistical analysis of the physical property parameters were carried out. The physical parameters of the geological bodies preliminarily divided in Table 1 are shown in Table 2, Table 3 and Table 4.

Table 4 Resistivity characteristics of geological bodies initially divided in a mining area

The distinguishability in this embodiment refers to whether the geological bodies can be distinguished from each other in terms of physical property parameters. If the physical property parameters of various geological bodies differ greatly, the distinguishable degree will be large, otherwise, the distinguishable degree will be small. From the above Tables 2, 3 and 4, it can be seen that the magnetic properties and densities of the Tianjia Formation 1 and Tianjia Formation 2 rocks overlap, and the degree of distinction is small. The magnetism and density of the rocks in the first member of the Chenjia Formation and the second member of the Chenjia Formation overlap, and the degree of differentiation is small. The physical property distinguishability between adjacent geological bodies in the formation age of geological bodies is obvious.

Step S300: Determine the target geological body from the preliminary divided geological bodies according to the difference and distinguishability of the physical property parameters.

During specific implementation, this embodiment refers to deep geological data such as deep boreholes and exploration line profiles, and according to the differences and distinguishability of the physical parameters, reasonably merges or increases the geological bodies that are initially divided, so as to determine the The target geological body. Due to the difference in physical parameters and the geological bodies with high distinguishability, it is easy to identify them in the interpretation of geophysical data later, and it is easy to distinguish different geological bodies. Therefore, in this embodiment, it is necessary to merge the above and below adjacent primary geological bodies whose physical property parameter difference and the distinguishability are both smaller than the first preset value into one target geological body, and combine the physical property difference and The preliminarily divided geologic bodies whose distinguishability is greater than the second preset value are divided into two target geologic bodies, that is, the increase of the target geologic bodies is realized. Of course, in this embodiment, the geological bodies that are initially divided that are beneficial to mineralization can also be regarded as a single target geological body as far as possible with the support of the degree of discrimination, so as to avoid being interfered by the geological bodies that are initially divided above and below.

For example, based on the physical parameters and distinguishability shown in Table 2, Table 3, and Table 4 above, the first and second members of the Tianjia Formation were merged into one target geological body, and the first and second members of the Chenjia Formation were merged into one target geological body. Other preliminary divided geological bodies are reserved as the target geological bodies of the 3D geological survey of the mining area, and the target geological bodies of the 3D geological survey of a certain mining area are determined in Table 5.

Table 5 The target geological body of 3D geological modeling determined in a mining area

Next, in this embodiment, the planar geological map, geophysical data inversion map or section map, and physical property parameters corresponding to the target geological body are acquired. Then compare and analyze the planar geological map, the inversion map or cross-section map of the geophysical data, and the physical parameters to analyze whether there is a corresponding relationship between the three. For example, if the plane geological map, geophysical data inversion map or cross-section map of the same target geological body is matched, the geophysical data inversion map or cross-section map is a low-value area, and the physical property parameters of the target geological body are also low-value. Then there is a corresponding corresponding relationship. On the contrary, if the planar geological map, geophysical inversion map or section map of the same target geological body is a low value area, but the physical property parameters of the target geological body are high value, then there is no corresponding corresponding relationship. And if it is determined that there is a corresponding corresponding relationship between the plane geological map, the geophysical data inversion map or section map, and the physical parameters, then it is confirmed that the target geological body is reasonable, otherwise the target geological body can be carried out. Adjust or refine. Finally, in this embodiment, the determined three-dimensional geological survey target geological body can be used to interpret the geophysical prospecting data in the work area, and establish a three-dimensional space model of the target geological body in the mining area. Use multi-source information fusion technology to determine 3D geological modeling. Conversely, the rationality of the division of the target geological body is checked.

It can be seen that the present invention determines the target geological body for three-dimensional modeling on the basis of traditional geological layering and rock classification, combined with geophysical two- and three-dimensional inversion data bodies such as gravity exploration, magnetic exploration and electrical exploration, etc. body.
