TABLE 4 geologic body resistivity characteristics for preliminary divisions of a certain mine area
The differentiability in this embodiment means that the geologic bodies cannot be differentiated from each other in the physical property parameters, and the differentiability is large when the physical property parameters of each geologic body are different from each other, and is small otherwise. As shown in tables 2, 3 and 4, the magnetic properties and densities of rocks in the first section of the farmyard set and the second section of the farmyard set overlap each other, and the degree of discrimination is small. The magnetism and the density of the first section of the Chen group and the second section of the Chen group are overlapped, and the distinguishability is small. The physical property distinction degree between adjacent geologic bodies is obvious in the geologic body formation time.
And S300, determining a target geologic body from the preliminarily divided geologic bodies according to the physical property parameter difference and the distinguishability.
In specific implementation, the preliminarily divided geologic bodies are reasonably combined or increased according to the physical property parameter difference and the differentiable degree by referring to deep geological data such as deep drilling holes, exploration line profile maps and the like, so that the target geologic bodies are determined. Due to the fact that the geologic bodies with large physical property parameter difference and distinguishability are easy to identify when geophysical prospecting data are decoded, and the different geologic bodies are easy to distinguish. Therefore, in this embodiment, the preliminarily selected geologic bodies, which are adjacent to each other in the upper and lower directions and have the physical property parameter difference and the differentiable degree both smaller than the first preset value, need to be merged into one target geologic body, and the preliminarily divided geologic bodies, which have the physical property difference and the differentiable degree both larger than the second preset value, need to be divided into two target geologic bodies, so that the target geologic bodies are increased. Of course, in this embodiment, the preliminarily divided geologic bodies favorable for mineralization can be used as individual target geologic bodies as much as possible under the condition of being supported by differentiation, so as to avoid interference by the preliminarily divided geologic bodies adjacent to each other above and below.
For example, based on the physical property parameters and the discriminative power shown in tables 2, 3, and 4, the first section and the second section of the field group are merged into one target geologic body, the first section and the second section of the aged group are merged into one target geologic body, other preliminarily divided geologic bodies are reserved as target geologic bodies for the three-dimensional geologic survey of the mining area, and the target geologic body for the three-dimensional geologic survey of the mining area is determined as table 5.
TABLE 5 target geologic body for three-dimensional geological modeling determined for a mine
Then, the embodiment acquires a planar geological map, a geophysical prospecting data inversion map or a section map and physical property parameters corresponding to the target geological body. And then putting the planar geological map, the geophysical prospecting data inversion map or the section map and the physical property parameters together for comparative analysis, and analyzing whether the planar geological map, the geophysical prospecting data inversion map or the section map and the physical property parameters have corresponding relations or not. For example, a planar geological map, a geophysical data inversion map, or a section map of the same target geologic body are correlated, the geophysical data inversion map or the section map is a low-value region, and the physical property parameter of the target geologic body is also a low value, so that there is a corresponding correlation. On the contrary, if the planar geological map, the geophysical inversion map or the section map of the same target geological body are low-value areas, and the physical property parameter of the target geological body is high, there is no corresponding relationship. And if the planar geological map, the geophysical prospecting data inversion map or the section map and the physical property parameters have corresponding relations, the target geological body is determined to be reasonable, otherwise, the target geological body can be adjusted or refined. Finally, the embodiment can utilize the determined three-dimensional geological survey target geologic body to interpret the geophysical prospecting data of the working area and establish a three-dimensional space model of the mining area target geologic body. And determining three-dimensional geological modeling by using a multi-source information fusion technology. And in turn, checking the rationality of the target geologic body division.
Therefore, the target geologic body is determined by combining the geophysical two-dimensional inversion data body and the geophysical three-dimensional inversion data body such as gravity exploration, magnetic exploration, electrical exploration and the like on the basis of determining the three-dimensional modeling target geologic body through traditional geologic stratification and rock classification. The method and the device for determining the target geologic body by integrating multiple information such as geology, geophysical, drilling and the like improve the interpretation precision of deep geophysical exploration data and have high implementability.
