Description

Technical Field

[0001] This invention belongs to the field of mine exploration technology, specifically relating to a geological exploration method, system, equipment and medium for mine excavation. Background Technology

[0002] A mine is a series of shafts or tunnels excavated to connect the surface to underground mineral deposits. The excavation of mines has a significant and far-reaching impact on the mining of mineral resources such as ore and coal. It not only affects the amount of infrastructure work, initial investment, and construction speed of the mine, but also determines the mine's production conditions and technical and economic indicators in the long term.

[0003] Mine geological exploration, following mineral resource surveys and exploration, encompasses all geological exploration work conducted from the start of mine excavation to the end of mineral resource extraction; it is also the geological exploration work carried out during mine construction and production. Mine geological exploration is closely linked to mine development, construction, and safe production, and is a crucial component of mineral resource extraction. The purpose of mine geological exploration is to obtain reliable geological data, identify geological conditions affecting mining production, improve reserve levels, increase recoverable reserves, meet the needs of various mine designs, and ensure normal production continuity and safe operation.

[0004] In existing technologies, a mine excavation path is typically determined based on pre-sampled geological information, and mine excavation operations are carried out based on this path. However, in using existing technologies, the inventors have discovered at least the following problems:

[0005] Due to limitations in sampling accuracy, early geological sampling data often cannot fully construct a geological model of the mining area. During the mine excavation process, there are often discrepancies between the actual geological information and the expected data. In such cases, continuing to excavate according to the pre-set mine excavation path can easily lead to mine excavation accidents. Summary of the Invention

[0006] The present invention aims to solve the above-mentioned technical problems to at least a certain extent. The present invention provides a geological exploration method, system, equipment and medium for mine excavation.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] In a first aspect, the present invention provides a geological exploration method for mine excavation, comprising:

[0009] The remote sensing image information and geological sampling information of the target mining area are acquired, and a three-dimensional geological model of the mining area is constructed based on the remote sensing image information and the geological sampling information.

[0010] Based on the three-dimensional geological model of the mining area, a three-dimensional model of the ore body to be mined within the target mining area that meets the preset mining conditions is obtained;

[0011] Based on the three-dimensional geological model of the mining area and the three-dimensional model of the ore body, mine excavation guidance information is obtained so that users can carry out mine excavation operations according to the mine excavation guidance information;

[0012] During the mine excavation operation, real-time reception of geological exploration data collected in the target mine exploration area is achieved.

[0013] The three-dimensional geological model of the mining area is updated based on the geological exploration data of the mine, resulting in an updated three-dimensional geological model of the mining area.

[0014] The mine excavation guidance information is corrected based on the updated three-dimensional geological model of the mining area and the three-dimensional model of the ore body to obtain corrected mine excavation guidance information, so that users can continue to carry out mine excavation operations based on the corrected mine excavation guidance information.

[0015] This invention enables dynamic updating of mine excavation guidance information, which helps improve the safety of mine excavation. Specifically, in the implementation of this invention, remote sensing image information and geological sampling information of the target mining area are acquired, and a three-dimensional geological model of the mining area is constructed based on the remote sensing image information and the geological sampling information. Then, a three-dimensional model of the ore body that meets the preset mining conditions within the target mining area is obtained based on the three-dimensional geological model of the mining area. Subsequently, mine excavation guidance information is obtained based on the three-dimensional geological model of the mining area and the three-dimensional model of the ore body, so that the user can carry out mine excavation operations according to the mine excavation guidance information. During the mine excavation operation, mine geological exploration data collected in the target mine exploration area is received in real time, and the three-dimensional geological model of the mining area is updated based on the mine geological exploration data to obtain an updated three-dimensional geological model of the mining area. The mine excavation guidance information is then corrected based on the updated three-dimensional geological model of the mining area and the three-dimensional model of the ore body, resulting in corrected mine excavation guidance information, so that the user can continue mine excavation operations according to the corrected mine excavation guidance information. This enables dynamic updating of mine excavation guidance information, which can solve the problem of inaccurate geological information in the mining area caused by the lack of precision in geological sampling, thereby improving the safety of mine excavation.

[0016] In one possible design, the geological sampling information of the mining area includes sampling point location information and geological borehole information of the sampling points; correspondingly, a three-dimensional geological model of the mining area is constructed based on the remote sensing image information of the mining area and the geological sampling information of the mining area, including:

[0017] Based on the remote sensing image information of the mining area, the topographic elevation information and surface outline information of the mining area are obtained;

[0018] Geological feature information is obtained based on the remote sensing image information of the mining area;

[0019] Based on the topographic elevation information and surface contour information of the mining area, a three-dimensional elevation model of the mining area is constructed.

[0020] The sampling point location information and the geological borehole information of the sampling points are inserted into the three-dimensional elevation model of the mining area to obtain the interpolated three-dimensional elevation model of the mining area.

[0021] Based on the interpolated three-dimensional elevation model of the mining area, the geological information of the target mining area is predicted to obtain the initial three-dimensional geological model of the mining area.

[0022] The feature information of the land features is inserted into the initial three-dimensional geological model of the mining area to obtain the three-dimensional geological model of the mining area.

[0023] In one possible design, a three-dimensional model of the ore body to be mined within the target mining area that meets the preset mining conditions is obtained based on the three-dimensional geological model of the mining area, including:

[0024] Receive the designated ore body identification information and determine whether the three-dimensional geological model of the mining area includes ore body stratigraphic information that matches the designated ore body identification information. If so, proceed to the next step.

[0025] Obtain the stratigraphic information of all ore bodies that match the specified ore body identification information, and generate an ore body envelope based on all the stratigraphic information of the ore bodies;

[0026] Obtain the ore body volume and ore body volume ratio of the ore body corresponding to the ore body stratigraphic information in the ore body envelope;

[0027] Determine whether the volume and proportion of the ore body meet the preset mining conditions. If so, output the ore body envelope as a three-dimensional model of the ore body to be mined that meets the preset mining conditions.

[0028] In one possible design, the orebody envelope is generated based on all orebody stratigraphic information, including:

[0029] Obtain the stratigraphic information of the ore body with the largest ore body volume among all ore body stratigraphic information;

[0030] The stratigraphic information of the ore body with the largest volume is set as the basic stratigraphic information of the ore body. Then, it is determined whether the distance between the stratigraphic information of other ore bodies and the basic stratigraphic information is greater than a preset distance threshold. If so, the stratigraphic information of the ore body with a distance greater than the preset distance threshold is removed until all the stratigraphic information of the ore body with a distance of no more than the preset distance threshold from the basic stratigraphic information is obtained. The stratigraphic information of the ore body is then set as the stratigraphic information of the adjacent ore body.

[0031] The orebody envelope is generated based on the stratigraphic information of the basic orebody and the stratigraphic information of the adjacent orebody.

[0032] In one possible design, obtaining the orebody volume and orebody volume ratio within the orebody envelope that corresponds to the orebody stratigraphic information includes:

[0033] Obtain the volume of the ore body envelope;

[0034] Obtain the ore body volume in the ore body envelope that corresponds to the ore body stratigraphic information;

[0035] Based on the envelope volume and the ore body volume, the proportion of the ore body volume in the ore body envelope corresponding to the ore body stratigraphic information is obtained.

[0036] In one possible design, the mine excavation guidance information includes mine start location information, mine end location information, and mine excavation path information from the mine start location information to the mine end location information; correspondingly, the mine excavation guidance information is obtained based on the three-dimensional geological model of the mining area and the three-dimensional model of the ore body, including:

[0037] Based on the three-dimensional geological model of the mining area and the three-dimensional model of the ore body, the three-dimensional model of the ore body is mapped vertically onto the upper surface of the three-dimensional geological model of the mining area to obtain the surface mapping area information of the ore body;

[0038] Based on the surface mapping area information of the ore body and the three-dimensional geological model of the mining area, the starting location information of the mine is obtained;

[0039] Based on the mine's starting location information and the ore body's three-dimensional model, the mine's ending location information is obtained;

[0040] Based on the mine start location information, the mine end location information, the three-dimensional geological model of the mining area, and the three-dimensional model of the ore body, the mine excavation path information from the mine start location information to the mine end location information is obtained.

[0041] In one possible design, after obtaining the updated three-dimensional geological model of the mining area, the method further includes:

[0042] Based on the updated three-dimensional geological model of the mining area, the three-dimensional model of the ore body, and the mine excavation guidance information, excavation risk information is generated for mine excavation operations based on the mine excavation guidance information;

[0043] The excavation risk level is obtained based on the excavation risk information. If the excavation risk level is greater than a preset level threshold, the three-dimensional geological model of the mining area is updated based on the mine geological exploration data. Otherwise, the mine geological exploration data collected in the target mine exploration area continues to be received.

[0044] In a second aspect, the present invention provides a geological exploration system for mine excavation, used to implement the geological exploration method for mine excavation as described in any of the preceding claims; the geological exploration system for mine excavation includes:

[0046] The ore body model generation module is communicatively connected to the mining area model construction module and is used to obtain a three-dimensional model of the ore body to be mined in the target mining area that meets the preset mining conditions based on the three-dimensional geological model of the mining area.

[0047] The guidance information generation module is communicatively connected to the ore body model generation module and is used to obtain mine excavation guidance information based on the three-dimensional geological model of the mining area and the three-dimensional model of the ore body, so that users can carry out mine excavation operations based on the mine excavation guidance information;

[0048] The exploration data acquisition module is used to receive real-time geological exploration data of the target mine exploration area during the mine excavation operation.

Obviously, the following description of the structure of the accompanying drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0058] Example 1:

[0059] This embodiment discloses a geological exploration method for mine excavation, which can be executed, but is not limited to, by a computer device or virtual machine with certain computing resources, such as a personal computer, smartphone, personal digital assistant or wearable device, or by a virtual machine.

[0060] like Figure 1 As shown, a geological exploration method for mine excavation may include, but is not limited to, the following steps:

[0061] S1. Obtain remote sensing image information and geological sampling information of the target mining area, and construct a three-dimensional geological model of the mining area based on the remote sensing image information and the geological sampling information.

[0062] In this embodiment, the geological sampling information of the mining area includes sampling point location information and geological borehole information of the sampling points; correspondingly, a three-dimensional geological model of the mining area is constructed based on the remote sensing image information of the mining area and the geological sampling information of the mining area, including:

[0063] S101. Obtain the topographic elevation information and surface contour information of the mining area based on the remote sensing image information of the mining area; it should be noted that the topographic elevation information of the mining area refers to the elevation information of different locations on the surface of the target mining area. In this embodiment, a DEM (Digital Elevation Model) model can be used to reconstruct the topographic surface of the mining area using spectral, texture, and geometric information from the remote sensing image of the mining area, thereby obtaining the topographic elevation information of the mining area. Specifically, a DEM model is a geographic information system data model that represents the surface elevation information of different areas in numerical form.

[0064] S102. Obtain ground feature information based on the remote sensing image information of the mining area; it should be noted that the ground feature information may be the ground feature information corresponding to buildings, roads, farmland, forests, etc.

[0065] S103. Based on the topographic elevation information and surface contour information of the mining area, a three-dimensional elevation model of the mining area is constructed;

[0066] S104. Insert the sampling point location information and the geological borehole information of the sampling points into the three-dimensional elevation model of the mining area to obtain the interpolated three-dimensional elevation model of the mining area.

[0067] S105. Based on the interpolated three-dimensional elevation model of the mining area, the geological information of the target mining area is predicted to obtain an initial three-dimensional geological model of the mining area;

[0068] S106. Insert the aforementioned feature information into the initial three-dimensional geological model of the mining area to obtain the three-dimensional geological model of the mining area.

[0069] S2. Based on the three-dimensional geological model of the mining area, obtain a three-dimensional model of the ore body of the target mining area that meets the preset mining conditions.

[0070] In this embodiment, a three-dimensional model of the ore body to be mined within the target mining area that meets the preset mining conditions is obtained based on the three-dimensional geological model of the mining area, including:

[0071] S201. Receive the specified ore body identification information and determine whether the three-dimensional geological model of the mining area includes ore body stratigraphic information that matches the specified ore body identification information. If yes, proceed to the next step; if no, determine that there is no ore body to be mined in the target mining area that matches the specified ore body identification information, and output ore body matching failure information so that the user can input other ore body identification information. It should be noted that the specified ore body identification information is user input information used to characterize the geological type of the ore body to be mined.

[0072] S202. Obtain the stratigraphic information of all ore bodies that match the specified ore body identification information, and generate an ore body envelope based on all the stratigraphic information of the ore bodies;

[0073] Specifically, in this embodiment,

[0074] Generate an orebody envelope based on all orebody stratigraphic information, including:

[0075] S2021. Obtain the stratigraphic information of the ore body with the largest ore body volume among all ore body stratigraphic information;

[0076] S2022. Set the stratigraphic information of the ore body with the largest volume as the basic ore body stratigraphic information, and sequentially determine whether the distance between the stratigraphic information of other ore bodies and the basic ore body stratigraphic information is greater than a preset distance threshold. If so, remove the stratigraphic information of ore bodies with a distance greater than the preset distance threshold until all stratigraphic information of ore bodies with a distance not greater than the preset distance threshold is obtained, and set the stratigraphic information of the ore body as the adjacent ore body stratigraphic information. It should be noted that in this embodiment, the distance between any stratigraphic information of ore bodies and the basic ore body stratigraphic information is the distance between the centroid of the stratigraphic information of the ore body and the centroid of the basic ore body stratigraphic information.

[0077] S2023. Generate an orebody envelope based on the stratigraphic information of the basic orebody and the stratigraphic information of the adjacent orebody.

[0078] It should be noted that in this embodiment, the stratigraphic information of the ore body with the largest ore body volume among all ore body stratigraphic information is used as the basic ore body stratigraphic information. Other ore body stratigraphic information is then filtered based on the distance between it and the basic ore body stratigraphic information, thereby obtaining the stratigraphic information of neighboring ore bodies corresponding to the basic ore body stratigraphic information. An ore body envelope is then generated based on the basic ore body stratigraphic information and the neighboring ore body stratigraphic information. This configuration ensures that the specified ore bodies within the ore body envelope are most concentrated, thus guaranteeing the subsequent mineability of the specified ore bodies.

[0079] S203. Obtain the ore body volume and ore body volume ratio of the ore body corresponding to the ore body stratigraphic information in the ore body envelope;

[0080] In this embodiment, obtaining the ore body volume and ore body volume ratio of the ore body corresponding to the ore body stratigraphic information within the ore body envelope includes:

[0081] S2031. Obtain the volume of the ore body envelope;

[0082] S2032. Obtain the volume of the ore body corresponding to the ore body stratigraphic information in the ore body envelope;

[0083] S2033. Based on the envelope volume and the ore body volume, obtain the ore body volume ratio within the ore body envelope that corresponds to the ore body stratigraphic information. It should be understood that, in this embodiment, the ore body volume ratio = ore body volume / envelope volume.

[0084] S204. Determine whether the volume and proportion of the ore body meet the preset mining conditions. If yes, output the ore body envelope as a 3D model of the ore body to be mined that meets the preset mining conditions. If no, determine that there is no ore body to be mined in the target mining area that matches the specified ore body identification information, and output ore body matching failure information so that the user can input other ore body identification information. It should be noted that in this embodiment, the preset mining conditions are that the volume of the ore body in the ore body envelope is greater than the preset volume, and the proportion of the ore body volume in the ore body envelope is greater than the preset proportion. In this embodiment, the preset volume and preset proportion can be determined according to the size of the mining project and are not limited here.

[0085] S3. Obtain mine excavation guidance information based on the three-dimensional geological model of the mining area and the three-dimensional model of the ore body, so that users can carry out mine excavation operations according to the mine excavation guidance information.

[0086] In this embodiment, the mine excavation guidance information includes mine start location information, mine end location information, and mine excavation path information from the mine start location information to the mine end location information; correspondingly, the mine excavation guidance information is obtained based on the three-dimensional geological model of the mining area and the three-dimensional model of the ore body, including:

[0087] S301. Based on the three-dimensional geological model of the mining area and the three-dimensional model of the ore body, the three-dimensional model of the ore body is mapped vertically onto the upper surface of the three-dimensional geological model of the mining area to obtain the surface mapping area information of the ore body;

[0088] S302. Based on the surface mapping area information of the ore body and the three-dimensional geological model of the mining area, the starting location information of the mine is obtained; it should be understood that the starting location information of the mine can be located within the area where the surface mapping area information of the ore body is located, or it can be located outside the area where the surface mapping area information of the ore body is located.

[0089] Specifically, in this embodiment, the starting location information of the mine is obtained based on the surface mapping area information of the ore body and the three-dimensional geological model of the mining area, including:

[0090] Based on the surface mapping area information of the ore body and the three-dimensional geological model of the mining area, it is determined whether the surface mapping area information of the ore body includes a surface area whose distance from the feature information of the three-dimensional geological model of the mining area is greater than a preset distance threshold and whose area is greater than a preset area threshold. If so, the midpoint location information of the surface area is used as the starting location information of the mine. If not, the midpoint location information of the surface area outside the surface mapping area information of the ore body, whose distance from the feature information of the three-dimensional geological model of the mining area is greater than a preset distance threshold, whose area is greater than a preset area threshold, and whose closest surface area is to the surface mapping area information of the ore body is selected as the starting location information of the mine.

[0091] This setup ensures that the starting point of the mine is as close as possible to the ore body to be mined, while also keeping the starting point away from ground features. This facilitates saving on mine excavation construction costs and avoids disrupting the normal lives of local residents during mine excavation operations.

[0092] S303. Based on the mine starting position information and the ore body three-dimensional model, obtain the mine ending position information;

[0093] Specifically, in this embodiment, the mine endpoint location information is obtained based on the mine starting location information and the ore body three-dimensional model, including:

[0094] S3031. Obtain all envelope points in the three-dimensional model of the ore body whose distance from the centroid of the three-dimensional model of the ore body is less than a preset value;

[0095] S3032. Obtain the envelope point with the smallest distance from the starting position information of the mine among all envelope points, and use this envelope point as the ending position information of the mine.

[0096] It should be noted that the mine end point location information corresponds to a certain envelope point in the ore body 3D model that is close to the centroid of the ore body 3D model, and the straight-line distance from the mine start point location information to the mine end point location information is the minimum.

[0097] S304. Based on the mine start location information, the mine end location information, the three-dimensional geological model of the mining area, and the three-dimensional model of the ore body, the mine excavation path information from the mine start location information to the mine end location information is obtained. In this embodiment, the mine excavation path information should avoid unstable zones such as collapse zones, fracture zones, and subsidence zones in the three-dimensional geological model of the mining area. The type of each zone can be confirmed based on the geological information in the three-dimensional geological model of the mining area, and will not be elaborated here.

[0098] S4. During the mine excavation operation, receive in real time the geological exploration data of the target mine exploration area.

[0099] S5. Update the three-dimensional geological model of the mining area based on the geological exploration data of the mine to obtain the updated three-dimensional geological model of the mining area.

[0100] S6. Based on the updated three-dimensional geological model of the mining area and the three-dimensional model of the ore body, the mine excavation guidance information is corrected to obtain the corrected mine excavation guidance information, so that the user can continue to carry out mine excavation operations according to the corrected mine excavation guidance information.

[0101] Specifically, in this embodiment, after obtaining the updated three-dimensional geological model of the mining area, the method further includes:

[0102] Based on the updated three-dimensional geological model of the mining area, the three-dimensional model of the ore body, and the mine excavation guidance information, excavation risk information is generated for mine excavation operations based on the mine excavation guidance information;

[0103] The excavation risk level is obtained based on the excavation risk information. If the excavation risk level is greater than a preset level threshold, the three-dimensional geological model of the mining area is updated based on the mine geological exploration data. Otherwise, the mine geological exploration data collected in the target mine exploration area continues to be received.

[0104] It should be noted that, based on the generation of excavation risk levels and their relationship with level thresholds, the excavation risk of the original mine excavation path information can be obtained. When the excavation risk level is greater than the preset level threshold, the three-dimensional geological model of the mining area is updated according to the mine geological exploration data, which can avoid the problem of consuming a lot of computing resources caused by frequently updating the mine excavation path information.

[0105] This embodiment enables dynamic updating of mine excavation guidance information, which helps improve the safety of mine excavation. Specifically, in this embodiment, during implementation, remote sensing image information and geological sampling information of the target mining area are acquired, and a three-dimensional geological model of the mining area is constructed based on the remote sensing image information and the geological sampling information. Then, a three-dimensional model of the ore body within the target mining area that meets preset mining conditions is obtained based on the three-dimensional geological model of the mining area. Subsequently, mine excavation guidance information is obtained based on the three-dimensional geological model of the mining area and the three-dimensional model of the ore body, so that the user can carry out mine excavation operations according to the mine excavation guidance information. During the mine excavation operation, mine geological exploration data collected in the target mine exploration area is received in real time, and the three-dimensional geological model of the mining area is updated based on the mine geological exploration data to obtain an updated three-dimensional geological model of the mining area. The mine excavation guidance information is then corrected based on the updated three-dimensional geological model of the mining area and the three-dimensional model of the ore body, resulting in corrected mine excavation guidance information, so that the user can continue mine excavation operations according to the corrected mine excavation guidance information. This enables dynamic updating of mine excavation guidance information, which can solve the problem of inaccurate geological information in the mining area caused by the lack of precision in geological sampling, thereby improving the safety of mine excavation.
