Description

Technical Field

[0001] The invention relates to the technical field of geological information processing, and in particular to a processing method for adding known geological information of coal mines to coalfield seismic interpretation software by using data processing. Background Art

[0002] At present, in the process of coalfield seismic interpretation, it is often encountered that some areas in the work area have been mined, and there will be a lot of information such as tunnels, working faces, actual faults, and collapse columns. Accurate use of this information will better guide the interpretation of seismic data and greatly improve the accuracy of seismic data interpretation. In the past, adding this information in GeoFrame, a common software for coalfield seismic interpretation, was mainly achieved by adding a few points in structural geological information such as tunnel turning points and fault traces, and then manually connecting these points in Basemap in comparison with the underground mining engineering drawings.

[0003] Problems and disadvantages of this approach include:

[0004] 1. Because there are many points that need to be extracted, such as turning points and faults in the tunnel, and they need to be added to the Basemap first, and then manually connected according to the mining engineering drawings, which leads to a large workload in the existing methods.

[0005] 2. Faults, sinkholes, etc. do not appear as straight lines on a plane, which requires the extraction of a large number of points to approximate the actual situation. If there are not enough points, the accuracy of geological information utilization will decrease. Summary of the invention

[0006] In order to effectively and accurately add known geological information to coalfield seismic interpretation software and greatly reduce the workload, the present invention provides a processing method for adding known geological information to coalfield seismic interpretation software.

[0007] A method for adding known geological information to coalfield seismic interpretation software, characterized by comprising the following steps:

[0008] S1, process the mining engineering plan, delete unnecessary geological information, retain the tunnel, actual fault, collapse column, coal seam thinning zone, scour zone and interpretation scheme, and save the processed mining engineering plan as a DXF file with a suffix;

[0009] S2, create a horizon and multiple fault names in GeoFrame software, and draw the fault trace of this horizon and this fault in the basemap of GeoFrame software;

[0010] S3, exporting the fault trace information drawn in Baemape as the first data file with the suffix dat;

[0011] S4, importing the DXF file in step S1 into the digitizing software, extracting the coordinate information of the points and lines, and exporting it into a second data file with a suffix of dat in combination with the corresponding layer information;

[0012] S5, processing the second data file according to the data requirements of the first data file, then importing the processed second data file into the first data file, and deleting the fault trace drawn in the basemap, and finally forming a third data file with a suffix of dat;

[0013] S6, loading the third data file into GeoFrame software and displaying it in Basemap.

[0014] Furthermore, in step S2, more than 10 faults need to be established in the GeoFrame software.

[0015] Furthermore, in step S3, when the fault trace information drawn in Baemape is exported as a first data file, it is also necessary to select the exported file format.

[0016] Furthermore, the selected file format is the fbm file format.

[0017] Furthermore, the digitization software commonly used in step S4 is DoubleFox software.

[0018] Beneficial effects: The present invention utilizes the data format of GeoFrame software to digitize the geological information of the known plane map, edits and processes the digitized geological information, and then re-imports it into GeoFrame. The operation is simple, and the accuracy of the known geological information can be effectively improved, and the workload is greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the technical means, features and effects of the patent of the present invention easy to understand, the present invention is further explained below in combination with specific implementation methods, taking an actual mining area as an example.

[0030] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure.

[0031] like Figure 1 As shown, a method for adding known geological information to coalfield seismic interpretation software includes the following steps:

[0032] Step S1, preliminarily process and analyze the collected mining engineering plan or the geological information plan to be imported, delete unnecessary point and line information, retain known geological information such as tunnels, actual faults, collapse columns, coal seam thinning zones, scour zones and previous interpretation schemes, and save them as A.DXF files, such as Figure 2 As shown;

[0033] Step S2, establish 11 faults in GeoFrame software and give them names. Here, more than 10 faults need to be established. In this embodiment, 11 faults are established, and one layer is established and named hd. Then, the fault traces of these 11 faults are drawn in the layer hd in the basemap.

[0034] Step S3, export the fault trace information drawn in Baemape as the first data file, namely, the B.dat data file, and select the format, generally the fbm format, such as Figure 3 As shown;

[0035] Step S4, import the A.DXF file in step S1 into the digitizing software, where the digitizing software generally adopts DoubleFox software, such as Figure 4 As shown, extract the coordinate information (x, y) of the point and line, and select the corresponding layer information (LAYER) line name information, such as Figure 5 As shown, it is exported as a second data file, namely C.dat file, such as Figure 6 As shown;

[0036] Step S5, sort C.dat according to the data format requirements in the B.dat file, and then import the processed C.dat file into the B.dat file. In this process, the points, line coordinates and line names extracted from C.dat need to be placed in the corresponding columns of the B.dat file. This is because the GeoFrame software reads the file according to the byte definition, that is, the corresponding information must be placed in the corresponding columns. In addition, the alignment method must also be consistent. During the alignment process, since the names and numbers of the lines may contain inconsistent numbers of characters, the appropriate file is exported, and the alignment method must also be consistent when placing the corresponding information in the corresponding bytes to ensure that it can be imported into the GeoFrame software. In addition, the fault trace information extracted from the Basemap must be deleted to form a third data file, namely the D.dat file, and ensure that the D.dat file is suitable for the GeoFrame software, such as Figure 7 shown.

[0037] Step S6, load the D.dat file into GeoFrame software and display it in Basemap, as shown in Figure 8 , Fig. 9 shown.

[0038] Through steps S1 to S6, known data can be quickly and accurately added to the seismic data interpretation system. The operation is simple, and the accuracy of known geological information can be effectively improved, and the workload can be greatly reduced.

[0039] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present disclosure should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
