Description
DESCRIPTION Invention Title ON-SITE 3D GEOLOGICAL MAPPING SYSTEM AND METHOD USING DEVICE FOR DISPLAYING BOUNDARY SURFACE OF GEOLOGICAL ELEMENTS
Technical Field
[1] Disclosed herein is a 3D geologic mapping system and method using an apparatus for indicating a boundary surface of geologic elements, and more particularly, a system and method using an indication apparatus that can implement results of examination of geologic features in a mine on a 3D mine map.
[2] Background Art
[3] Geologic maps are created based on the sorts of rocks, distribution of strata, configuration rocks, sequential relationships, geologic structures, creation dates and the like. Among the geologic maps, mine geologic maps are created based on distribution of rocks in a mine, tectonic lines of joints and faults and the like, distribution of ore bodies and mineralized zones and alteration zones. To create the mine geologic maps, experts perform geologic examination in mines, investigate into geologic features, and display the features on plane mine maps.
[4] The plane mine geologic maps are geologic maps drawn on paper. FIG. 1 shows an example of a mine geologic map of the related art.
[5] As shown in FIG. 1, an ordinary mine geologic map may include a remark, a scale, a direction, a mine shape and the like. Based on the elements included in the remark, experts can record and find geologic features in mines.
[6] The mine geologic map is a two-dimensional one. Accordingly, it is difficult to show all sorts of geologic information on an inside of a mine. Further, it is hard to interpret a mine geologic map including various types of information.
[7] There has been no technology for helping to easily understand the sorts of rocks, distribution of strata, configuration rocks, sequential relationships, geologic structures, creation dates, joints and faults, tectonic lines, ore bodies and mineralized zones, distribution of alteration zones and the like.
[8] An underground tunnel mapping technology is disclosed in Korean Patent No. 10-0933329 (Patent document 1). Patent document 1 relates to an automatic control equipment and method for tunnel mapping, which can help to predict distribution and scales ofjoints in front of a face of a tunnel, using data of the face of the tunnel scanned with a 3D laser scanner and image information on the face of the tunnel captured by a digital camera in a construction site of the tunnel.
[9] Patent document 1 is to make tunnel face mapping possible in a tunnel construction site without a geologic expert for analyzing mapping. In this case, 3D modeling for an underground tunnel is possible, but it is impossible to obtain information that would otherwise be obtained from a mine geologic map.
[10] Thus, there is a growing need for a technology for helping to easily understand the sorts of rocks, distribution of strata, configuration rocks, sequential relationships, geologic structures, creation dates, joints and faults, tectonic lines, ore bodies and mineralized zones, distribution of alteration zones and the like.
[11] It is to be understood that, if any prior art information is referred to herein, such reference does not constitute an admission that the information forms part of the common general knowledge in the art, in Australia or any other country. Description of Invention Technical Problem

[60] 3D geologic mapping system using apparatus for indicating boundary surface of geologic element
[61] An indication apparatus, as a main part of a 3D geologic mapping system using an apparatus for indicating a boundary surface of geologic elements according to one embodiment, is described with reference to FIG. 2.
[62] FIG. 2 is a cross-sectional view for describing a configuration of an indication apparatus of a 3D geologic mapping system using an apparatus for indicating a boundary surface of geologic elements according to the present disclosure.
[63] In an indication apparatus 100 of the 3D geologic mapping system according to one embodiment, an angle may be adjusted. The indication apparatus 100 of the 3D geologic mapping system may be attached to a partial surface in a mine to be used. As illustrated in FIG. 2, the indication apparatus 100 may include an attachment part 110, an identification part 120, and a rotational shaft 130.
[64] The attachment part 110 according to one embodiment may be a component attached to a part of a surface in a mine and may be formed into a predetermined-sized plate. The attachment part 110 and the identification part 120 may connect to each other in a swivable manner. When the identification part 120 is swiveled in a state in which the attachment part 110 is attached to a par of the surface in the mine, a contained angle (a) between the attachment part 110 and the identification part 120 may be adjusted.
[65] As a result of adjustment of the contained angle (a) between the attachment part 110 and the identification part 120, faults estimated from a boundary surface of a rock on the surface in the mine may be expressed. That is, a plurality of indication apparatuses 100 may be installed at places on the surface in the mine. Accordingly, faults of the rock before formation of the mine may be estimated, and angles of the plurality of indication apparatuses 100 may be adjusted to express the faults of the rock.
[66] The identification part 120 may connect to the attachment part 110 and may be disposed to protrude with respect to the surface in the mine. Particularly, the identification part 120 may have a specific shape for each of the geologic elements at the center thereof. For example, a shape formed in the identification part 120 of the indication apparatus 100 attached may vary depending on the type of a rock, and the shape may include a triangular shape, a circular shape and the like.
[67] Additionally, the identification part 120 may be made of an opaque material, e.g., a metallic material. Accordingly, when a shape in the mine is scanned by the scan device, scanning may be performed in the state in which the indication apparatus 100 is attached to the surface in the mine, and then when scanning results are analyzed, the sorts of rocks and estimated faults may be readily distinguished and identified.
[68] The rotational shaft 130 may be provided on one side of the attachment part 110, and the identification part 120 may be rotated with respect to the rotational shaft 130 to adjust an angle between the identification part 120 and the attachment part 110.
[69] In another embodiment, the indication apparatus 100 may be a metallic plate with a fold line. Accordingly, the attachment part 110 and the identification part 120 may be divided by the fold line, and an angle may be adjusted based on a degree of folding.
[70] As illustrate in FIG. 2, the attachment part 110 may be attached by an adhesive onto the surface 200 in the mine including a sedimentary rock and an igneous rock. In this case, the rotational shaft 130 between the attachment part 110 and the identification part 120 may be disposed along a boundary line between the sedimentary rock and the igneous rock, for example.
[71] The identification part 120 according to the present disclosure is specifically described with reference to FIGS. 3a and 3b.
[72] FIG. 3a and FIG. 3b are perspective views for describing embodiments of an indication apparatus 100 of a 3D geologic mapping system using an apparatus 100 for indicating a boundary surface of geologic elements according to the present disclosure.
[73] As illustrated in FIG. 3a, the identification part 120 of the indication apparatus 100 may include a body portion 121 and a triangular identification shape 122. An identification part 120'of another indication apparatus 100 may include a body portion 121' and a circular identification shape 122'. A plurality of indication apparatuses 100 having different identification shapes 122 may be disposed on the surface in the mine.
[74] The plurality of indication apparatuses 100 may have different contained angles (a and P), and the contained angle may be adjusted to display an angle at which a boundary surface such as a fault met by different sorts of rocks formed on the surface in the mine is formed, for example.
[75] The angle of the boundary surface of the fault in the mine may be estimated based on a boundary line between different rocks, formed at places in the mine, and may be displayed by the plurality of indication apparatuses 100.
[76] As illustrated in FIG. 3b, an identification part 120 of an indication apparatus
100 according to another embodiment may be manufactured to have different shapes in itself, instead of having an additional body portion 121 and a triangular identification shape 122.
[77] An identification part 120' of another indication apparatus 100 may have a circular shape. A plurality of indication apparatuses 100 with the identification part 120 and 120' having different shapes may be installed on the surface in the mine.
[78] When the identification part 120 and 120' in itself has a specific shape, the identification part of the indication apparatus may be scanned more readily by the scan device 400.
[79] In the case of a drone in which a light detection and ranging sensor (a LiDAR sensor) is installed in the scan device 400 to scan a shape in a mine, the identification part 120 and 120' itself may have a specific shape, as illustrated in FIG. 3b.
[80] Like the indication apparatuses 100 in FIG. 3a, the plurality of indication apparatus 100 installed may have different contained angles (a and P), and the contained angle may be adjusted to display an angle at which a boundary surface such as a fault met by different sorts of rocks formed on the surface in the mine is formed, for example.
[81] The angle of the boundary surface of the fault in the mine may be estimated based on a boundary line between different rocks, formed at places in the mine, and may be displayed by the plurality of indication apparatuses 100.
[82]
[83] Components of the 3D geologic mapping system using an apparatus for indicating a boundary surface of geologic elements according to one embodiment are described with reference to FIG. 4.
[84] FIG. 4 is a conceptual view for describing a 3D geologic mapping system using an apparatus 100 for indicating a boundary surface of geologic elements according to the present disclosure.
[85] The 3D geologic mapping system using an apparatus 100 for indicating a boundary surface of geologic elements according to the present disclosure may include an indication apparatus 100 an angle of which is adjustable, a scan device 400 configured to scan a shape inside a mine in a state in which the indication apparatus 100 is installed, and a server 500 configured to analyze scanning results generated by the scan device 400 and to generate a 3D mine geologic map on which geologic elements are displayed.
[86] In the system having the above configurations, as a result of adjustment of an angle of the indication apparatus 100, faults inside the mine, in which the indication apparatus 100 is installed, maybe expressed.
[87] The scan device 400, for example, may be a drone that is provide with a LiDAR sensor to scan the shape in the mine. Accordingly, the scan device 400 may clearly and readily scan the shape in the mine where the indication apparatus 100 is installed, and scanning results may be stored in the server 500 as image data.
[88] According to one embodiment, a plane mine geologic map 300 to be input to the server 500 may be further included. The plane mine geologic map 300, as illustrated in FIG. 1, may be a plane mine geologic map that is created previously. Mine geologic elements, displayed on the plane mine geologic map, may be identified, and the plane mine geologic map 300 may be used as reference information in a step of installing the indication apparatus100. The identification using the plane mine geologic map 300 may be performed by the server 500 through a predetermined algorithm.
[89] When the plane geologic elements included in the plane mine geologic map 300 are identified, the indication apparatus 100 may be attached to the surface 200 in the mine based on the plane geologic elements. As the indication apparatus 100 is attached to the surface 200 in the mine, distribution of the geologic elements displayed on the 3D mine geologic map may be determined.
[90] The server 500 may include a 3D mine geologic map generator 530 configured to analyze a mine scan database (DB) 510 and scanning results from the mine scan DB 510 and to generate a 3D mine geologic map, for example.
[91] The server 500 may further include a mine geologic map DB 520 in which the mine geologic map DB 520 and the plane mine geologic map 300 are stored. The server 500 may further include a 3D mine geologic map DB 540 in which the 3D mine geologic map is stored.
[92] The 3D geologic mapping system using an apparatus for indicating a boundary surface of geologic elements according to one embodiment may further include a terminal 600 capable of communicating with the server 500. A 3D mine geologic map from the server 500 may be displayed on the terminal 600, for example.
[93] A state in which the indication apparatus 100 is installed is described with reference to FIG. 5.
[94] FIG. 5 is a view showing a state in which an indication apparatus of a 3D
geologic mapping system using an apparatus for indicating a boundary surface of geologic elements according to the present disclosure is installed inside a mine.
[95] As illustrated in FIG. 5, the indication apparatus 100 may be installed on the surface 200 in the mine such that faults are expressed. In this case, a plurality of indication apparatuses 100 may be installed on the surface 200 in the mine at predetermined intervals and attached by an adhesive such as a urethane-based adhesive or a general-purpose adhesive.
[96] In the indication apparatus 100 according to the present disclosure, angles may be adjusted, and a disappearing boundary surface may be expressed. The identification shape 122 of the identification part 120 may be formed based on a combination of various symbols. Accordingly, configurations of rocks in a mine may be expressed in various ways and may be readily identified.

[102] As illustrated in FIG. 6, the 3D geologic mapping method using an apparatus for indicating a boundary surface of geologic elements according to one embodiment, may include: installing an indication apparatus, an angle of which is adjustable, in a mine (S120); scanning a shape in the mine, in which the indication apparatus is installed, by a scan device (S200); analyzing scanning results obtained by the scan device (S300); and generating a 3D mine geologic map based on geologic element data that is obtained as a result of analysis of scanning results (S400).
[103] As an angle of the indication apparatus 100 is adjusted, faults in the mine, where the indication apparatus 100 is installed, maybe expressed on a 3D mine geologic map.
[104] In this case, a step of determining whether there is a plane mine geologic map
1 1;
300 (S100) may be performed in advance. When there is a plane mine geologic map 300, the plane mine geologic map 300 may be input to the server 500 (SI10). Based on the plane mine geologic map 300 input, geologic elements may be readily expressed on the surface in the mine by the indication apparatus 100.
[105] As illustrated in FIG. 7, analyzing scanning results obtained by the scan device 400 (S300) may include identifying the indication apparatus 100 from the scanning results (S310); and identifying a shape and an angle of the indication apparatus 100 (S320), for example. Specifically, the shape and angle of the indication apparatus 100 may be distinguished and calculated by the 3D mine geologic map generator 530 of the server 500 based on a predetermined algorithm.
[106] Additionally, as illustrated in FIGS. 8 and 9, the identified indication apparatus 100 may be expressed as a geologic element on the 3D mine geologic map according a predetermined expression method (330).
[107] FIG. 8 is a view for describing an example of a 3D geologic map implemented with a 3D geologic mapping system using an apparatus for indicating a boundary surface of geologic elements according to the present disclosure.
[108] FIG. 9 is a view for describing an example of a 3D geologic map implemented with a 3D geologic mapping system using an apparatus for indicating a boundary surface of geologic elements according to the present disclosure.
[109]
[110] According to the present disclosure, the sort of a rock in a mine, distribution of strata, tectonic lines of joints and faults and the like, distribution of ore bodies and mineralized zones and alteration zones may be easily expressed through a 3D model. A 3D mine map may be obtained through a drone (various types of drones such as flying drones, travel drones and the like) equipped with a LiDAR sensor to combine pieces of geologic information on the 3D mine map. In this case, a coordinate value in a 3D mine and a distance value on the plane mine geologic map may correspond and may be matched. Accordingly, a geologic map that is previously created may also be changed into a 3D map.
[111] When an inside of a mine is examined later, examination results of the inside of the entire mine may be implemented on a 3D mine map. Thus, a mine geologic map may be implemented in more detail. The mine geologic map may be highly useful for a spacial coordinate-based 3D software.
[112]
