Description

Technical Field

[0001] The invention mainly relates to the technical field of geological exploration, and in particular to a method for graphical geological logging of exploration pits. Background Art

[0002] Before the construction of underground projects, the arrangement of exploration pits is a common means of understanding geological conditions. Surveyors can enter the exploration pits to directly observe and sample geological phenomena, test the reliability of drilling and geophysical data and results, record and describe the revealed geological conditions in detail, and obtain relatively accurate geological data.

[0003] Traditional exploration pit geological cataloging still uses paper cataloging. First, draw the display diagram of the four side walls and the bottom of the exploration pit on paper coordinate paper and establish the corresponding two-dimensional coordinate system. Then, use two-dimensional coordinates to outline the geometric information of the geological outcrop lines on the side walls and the bottom of the pit on the display diagram, and separately record the corresponding geological features and the geological topological relationship between each other and the attribute information of the corresponding geological objects; then complete the electronic transcription indoors and draw the geological outcrop sketch of each exploration pit. Not only is the operation process time-consuming and inefficient, but also each sketch is independent of each other and lacks uniformity. It is difficult to establish a spatial relationship with other explorations (such as drilling), which directly affects the utilization rate of the cataloging data and cannot be directly used in three-dimensional geological modeling and spatial analysis.

[0004] With the popularity of mobile electronic devices such as tablet computers, some institutions have studied the method of using electronic coordinate paper to replace paper coordinate paper for exploration pit cataloging. However, they only changed the form of the recording medium and did not solve the three practical problems in the overall exploration process: 1) The data obtained from each exploration pit and other exploration methods, such as drilling, are independent of each other and lack uniformity. They cannot be verified and corrected in a set of spatial systems according to the three-dimensional spatial relationship and cataloging time sequence, and do not meet the requirements of subsequent three-dimensional geological modeling, spatial analysis, and design calculations; 2) They only simply record the geometric information and attribute information of the dividing line, ignoring the spatial topological relationship between the geological dividing lines. They mainly describe the phenomenon, but pay insufficient attention to the internal relationship, and the recorded information tends to be single; 3) The degree of standardization of geological description is insufficient, and the description of geological characteristics is greatly affected by the cognitive ability and experience of on-site geologists. The degree of understanding of geological phenomena and the recording method are inconsistent, which affects the overall quality of basic data and cannot expand the direct use of original data for information analysis. Summary of the invention

[0005] Technical Problems Solved by the Invention

[0006] A graphical geological cataloging method for exploration pits is provided to solve the problem that the data obtained from exploration pits and other exploration methods are independent of each other, lack uniformity, and cannot be verified and corrected in a spatial system according to three-dimensional spatial relationships and cataloging time sequence.

[0007] The technical solution adopted by the present invention to solve the above technical problems

[0008] A method for graphical geological logging of exploration pits, comprising:

[0009] Step S1: establishing a three-dimensional engineering coordinate system, and determining the spatial position and geometric dimension information of the exploration pit based on the established three-dimensional engineering coordinate system;

[0010] Step S2: establishing a four-wall expansion diagram of the exploration pit and a pit bottom display diagram of the exploration pit at different excavation depths according to the spatial position and geometric size information of the exploration pit;

[0011] Step S3: drawing geological boundaries and setting geological object attribute information in the four-wall development diagram of the exploration pit and the pit bottom display diagram at different excavation stages of the exploration pit;

[0012] Step S4: transforming geological boundaries and geological object attribute information into the three-dimensional engineering coordinate system according to the relationship between the four-wall development diagram of the exploration pit and the pit bottom display diagram at different excavation stages and the three-dimensional engineering coordinate system.

[0013] Furthermore, step S2 specifically includes:

[0014] According to the spatial position and geometric size information of the exploration pit, a vertex of the exploration pit is selected as a feature point, a plumb line passing through the feature point is used as a feature line, the four walls of the exploration pit are unfolded into a plane according to the direction of the feature line, and the first local coordinate system is established according to the unfolding order, with the top boundary of the four walls of the exploration pit perpendicular to the feature line as the horizontal axis and the depth of the exploration pit as the vertical axis;

[0015] A second local coordinate system is established with the intersection of the sub-section corresponding to the excavation depth of the exploration pit and the characteristic line as the origin, and with the intersection of the sub-section and two adjacent walls of the exploration pit characteristic line as the horizontal axis and the vertical axis;

[0016] Draw the unfolded diagram of the four walls of the exploration pit in the first local coordinate system, and draw the pit bottom display diagram corresponding to the excavation depth in the second local coordinate system.

[0017] Furthermore, step S3 also includes: recording the geological topological relationship between the geological objects and the geological boundaries, and establishing the internal connection of the geological boundaries according to the geological topological relationship.

[0018] Furthermore, the geological topological relationship between the geological objects and the geological boundaries recorded specifically includes determining the upper and lower relationship of the geological objects and the upper and lower geological boundaries corresponding to their own boundaries through the direction of the characteristic lines, establishing the concept of the segment body of the geological objects, and dividing the geological cataloging objects into continuum, discontinuum and separate lines;

[0019] The geological objects of the continuum are arranged seamlessly along the characteristic line direction, and a single geological object has an upper and lower geological boundary along the characteristic line direction, and the lower boundary of the geological object of the previous line is the upper boundary of the geological object of the next line;

[0020] There is a discontinuity in the arrangement of geological objects along the characteristic line of the discontinuity, and there is no concept of upper and lower sequences, but a single geological object has an upper and lower geological boundary along the characteristic line;

[0021] The separate line is a single closed line and a non-closed line.

[0022] Furthermore, the geological cataloging objects include stratum lithology, structural planes, weathering unloading, rock mass structure segmentation, groundwater segmentation, karst and groundwater seepage.

[0023] Furthermore, the method for setting the geological object attribute information in step S3 is: establishing a standard dictionary library, and using the geological dictionary types and values ​​in the standard dictionary library to enter the geological object attribute information.

[0024] Further, the geological dictionary types include a standard dictionary of stratum lithology, a standard dictionary of weathering unloading, a standard dictionary of rock mass structure segmentation, a standard dictionary of groundwater segmentation, a standard dictionary of structural planes, and a standard dictionary of groundwater seepage;

[0026] Beneficial effects of the present invention

[0027] The method for graphically cataloging a test pit described in the present invention first determines the spatial position and geometric size information of the test pit in the established three-dimensional engineering coordinate system, and then establishes a four-wall development diagram containing the corresponding local coordinate system and a pit bottom display at different excavation depths according to the spatial position and geometric size information of the test pit. Figure 2 Dimensional diagram, displayed on the four walls and the bottom of the pit Figure 2 Draw geological boundaries in the 3D map and add geological object attribute information. Then, based on the relationship between the four-wall expansion map and the pit bottom display map at different excavation depths and the 3D engineering coordinate system, restore the geological boundaries and geological object attribute information to the 3D engineering coordinate system. Use it together with other survey objects for 3D modeling and spatial analysis, and realize comparative analysis of multiple survey objects in the same 3D space to improve the coordination of exploration data. At the same time, merging the two processes of on-site entry of geological information and electronicization of geological information can also reduce the process and errors of subsequent manual re-transcription of paper catalog information.

[0028] After the geological boundary is delineated in the present invention, the connection between the geological object and the geological boundary is further established according to the topological relationship of the geological object, so as to facilitate the direct call of the corresponding geological boundary data in the single geological three-dimensional modeling and statistical analysis; and in the subsequent analysis of the overall geological object, it can be directly associated with the corresponding geological boundary that has been determined on site, so as to reduce the subsequent data processing volume when a large number of errors occur due to the lack of on-site related data reference and the need for manual re-matching.

[0029] In the present invention, when setting the attribute information of the geological object, the geological dictionary type and value description in the standard dictionary library are directly selected, which can reduce the memory burden of the cataloging personnel, improve the efficiency of on-site cataloging, standardize the input to improve the cataloging quality, and facilitate the automated sorting of subsequent internal work.

[0040] like Figure 1 As shown, the method for graphically cataloging a test pit described in the present invention specifically includes step S1, establishing a three-dimensional engineering coordinate system, and determining the spatial position and geometric size information of the test pit based on the established three-dimensional engineering coordinate system. Select a vertex of the test pit as a feature point, and determine the position of the feature point in the three-dimensional engineering coordinate system. Taking the test pit TK01 in this embodiment as an example, the selected feature point is Figure 2 The coordinates of point 1 are (X1=100, Y1=100, Z1=0), and the plumb line passing through point 1 is used as the characteristic line. The azimuth angle of the wall of the exploration pit TK01 is X°, and the four walls of the exploration pit are perpendicular to each other. Figure 2 The azimuth angles of the 2nd, 3rd and 4th walls of the exploration pit are shown as X°+90°, X°+180° and X°+270° respectively; in this embodiment, the azimuth angle of the 1st wall of the exploration pit is 45°, and the azimuth angles of the 2nd, 3rd and 4th walls of the exploration pit are 135°, 225° and 315° respectively, and the length D=2m, width L=3m and pit depth H=5m of the exploration pit are recorded.

[0041] Step S2: Figure 3 As shown, in this embodiment, the exploration pit TK01 is unfolded into a plane along the characteristic line, and the horizontal axis of the first local coordinate system is marked with the length of each wall in the order of wall 1, wall 2, wall 3, and wall 4 in the same coordinate system, that is, the marking dimensions of the horizontal coordinate axis are: 0~D, 0~L, 0~D, 0~L, the width D is 2, and the length L is 3; the four walls share a vertical axis along the characteristic line of the exploration pit, the marking dimensions of the vertical axis are 0~H, and the value of H is 5.

[0042] like Figure 4 As shown, the excavation depth of TK01 is H1=4m, and the depth of TK02 is H2=6m to establish the second local coordinate system; the vertical axis of the second local coordinate system is the intersection line of the excavation depth sub-section and wall 1, corresponding to the value range of 0~D, the width D value is 2, and the horizontal axis of the second local coordinate system is the intersection line of the sub-section and wall 4, corresponding to the value range of 0~L, and the length L is 3.

[0043] According to the actual conditions of the four walls of the exploration pit, a display diagram of the four walls of the exploration pit is established in the first local coordinate system, and according to the conditions of the pit bottom at different excavation depths, a display diagram of the pit bottom at different excavation depths is established in the second local coordinate system.

[0044] Step S3: Draw geological boundaries and set geological object attribute information in the four walls display diagram of the exploration pit and the pit bottom display diagram at different excavation stages of the exploration pit.

[0045] like Figure 5 As shown, the geological boundaries of the stratum lithology are outlined on the electronic coordinate display map of the four walls of TK01. For example, the geological boundaries of sandstone, mudstone and dolomite are outlined. Since the stratum lithology is a continuum, the upper boundary of the sandstone is the exploration pit mouth, that is, the surface line, and the lower boundary is the boundary between sandstone and mudstone; the upper boundary of the mudstone is automatically taken from the lower boundary of the sandstone, and the lower boundary is taken from the boundary between mudstone and dolomite; the upper boundary of the dolomite is automatically taken from the lower boundary of the mudstone. If the lower boundary is not outlined, the bottom boundary of the exploration pit is taken by default, and a matching relationship between the stratum lithology and the geological boundaries is established.

[0046] like Figure 6 As shown in the electronic display of the four walls of the exploration pit TK01, for the joint 1 without thickness, the joint line can be directly drawn; Figure 7 As shown in the figure, the starting boundary of fault 1 with a thickness is drawn on the bottom display map of the exploration pit TK01 with a depth of H1 = 4m and the exploration pit TK02 with a depth of H2 = 6m, and the specified thickness is automatically offset downward along the longitudinal axis to generate the corresponding bottom boundary of the fault; Figure 8 As shown, for individual line catalog objects and independently closed catalog objects, such as linear seepage bodies and intrusion bodies, a single non-closed broken line table can be directly outlined on the electronic coordinate display diagram to represent the linear type of groundwater seepage, and a closed line can be used to outline the porous seepage type and intrusion body 1 of groundwater seepage.

[0047] Preferably, the geological topological relationship between geological objects and geological boundaries is further recorded in this embodiment, and the internal connection of the geological boundaries is established according to the defined geological topological relationship, so as to facilitate the direct call of the corresponding geological boundary data during the single geological three-dimensional modeling and statistical analysis, and in the subsequent analysis of the overall geological object, it can be directly associated with the corresponding geological boundary that has been determined on site, thereby reducing the subsequent large-scale data processing, such as three-dimensional geological stratification, layer thickness statistics, structural surface thickness statistics, etc., which result in a large number of errors when manual re-matching is required due to the lack of on-site related data reference.

[0048] In this embodiment, the geological topological relationship between geological objects and geological boundaries is recorded, which specifically includes determining the upper and lower relationship of geological objects and the upper and lower geological boundaries corresponding to their own boundaries through the direction of characteristic lines during cataloging, and establishing the concept of segmented bodies of geological objects. Specifically, geological cataloging objects are divided into three categories: 1) Continuum: Stratigraphic lithology, rock mass structure segmentation, weathering, unloading, and groundwater segmentation are continua. The characteristics of the continuum are that geological objects are seamlessly arranged along the characteristic line direction, and a single geological object has an upper and lower geological boundary along the characteristic line direction. The lower boundary of the geological object of the previous item is the upper boundary of the next item: establishing the start and end boundaries of weathering and unloading, and the upper and lower geological boundaries of the strata. Boundaries, top and bottom plates of karst, coverage of groundwater segments, etc.; 2) Non-continuum: The characteristic of non-continuum is that there are interruptions in the arrangement of geological objects along the characteristic line, and there is no concept of upper and lower sequences, but a single geological object has upper and lower geological boundaries along the characteristic line. Structural surfaces are divided into thick structural surfaces, i.e. faults, and non-thick structural surfaces, i.e. joints. The former has separate starting and ending boundaries, and the latter is a single boundary; 3) Single line cataloging: The characteristic is that this type of geological objects do not have the concept of upper and lower between themselves. Groundwater seepage can be created using a single closed line and a non-closed line, and the intrusive body creates an outcrop line through a closed line.

[0049] Preferably, when entering geological attribute information, geological attributes are selected from the established standard dictionary library. The dictionary types in the standard dictionary library include: 1) The values ​​of the stratum type in the stratum lithology are: overburden and bedrock. The soil type values ​​for the overburden type are: coarse sand, medium sand, fine sand, silt, clay, gravel, etc., and the genesis types are: artificial accumulation, alluvial, flood, colluvial, slope accumulation, residual accumulation, etc.; the rock type values ​​for the bedrock type are: hard rock, medium hard rock, relatively soft rock, soft rock, etc., and the genesis types are: sedimentary rock, metamorphic rock, intrusive rock, rock flow layer; 2) The standard dictionary and corresponding values ​​of weathering and unloading are: a) unloading process The values ​​of weathering degree are: no unloading, strong unloading, weak unloading, deep unloading; b) Weathering degree values: strongly weathered interlayer, fully weathered, strongly weathered, weakly weathered lower section, weakly weathered upper section, weakly weathered, slightly weathered, and no weathering of the overburden; 3) The standard dictionary and corresponding values ​​of rock mass structure segmentation are: a) Rock mass integrity: complete, relatively complete, poor integrity, relatively broken, broken; b) Structural surface development degree: very developed, developed, relatively developed, moderately developed, slightly developed, undeveloped; c) Rock mass structure type: blocky structure, layered structure, mosaic structure, fragmented structure, scattered structure ;4) The standard dictionary and pull-down values ​​for groundwater segmentation are: a) Groundwater state: wet, seepage, dripping, linear flow, gushing, dry; 5) The standard dictionary and pull-down values ​​for karst are: a) The standard dictionary and corresponding values ​​for karst are karst types: cave type, fissure type, pipeline type, large cave; 6) The standard dictionary and pull-down values ​​for structural plane are: a) Fault type: normal fault, reverse fault, thrust fault, shear fracture (joint), structural fracture (joint), primary fracture (joint); b) Extension: single wall penetration, multi-wall penetration; c) Structural plane Grades: Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ; d) Groundwater conditions: moist, seepage, dripping, linear flow, gushing, dry; e) Filling conditions: broken particles, unclear, cemented, no filling, rock block and debris type, debris and mud type, mud and debris type; f) Structural types: compression zone, bedding dislocation zone, bedding dislocation zone, deep crack; g) Undulating and rough conditions: straight and rough, undulating and rough, straight and smooth, undulating and smooth; h) Opening degree: closed, slightly open, open; 7) The standard dictionary and pull-down values ​​of groundwater seepage are: a) Seepage point type: rising spring, descending spring.

[0050] like Figure 5 As shown, in this embodiment, the formation type of the sandstone of formation 1 is directly set as bedrock, the rock type is relatively soft rock, and the genetic type is sedimentary rock in the established standard dictionary library; the formation type of the mudstone of formation 2 is bedrock, the rock type is soft rock, and the genetic type is metamorphic rock; the formation type of the dolomite of formation 3 is bedrock, the rock type is medium hard rock, and the genetic type is metamorphic rock; Figure 6 and 7Among them, the fault type of fault 1 is normal fault, the filling is quartz filling, the structural surface grade is grade I, the structural type is compression zone, the filling of joint 1 is rock debris and mud type, the roughness is straight and smooth, and the opening is slightly increased; for example, Figure 8 Among the groundwater seepage, the seepage type of linear seepage is rising spring, and the seepage type of pore seepage is descending spring.

[0051] Step S4: Fig. 9 As shown, according to the transformation relationship between the four-wall unfolding diagram in the first local coordinate system of the pit exploration TK01 and the pit bottom display diagram at different excavation depths in the second local coordinate system and the three-dimensional engineering coordinate system, the stratum lithology recorded by the pit exploration TK01 is transformed into the three-dimensional engineering coordinate system, and is located in the same three-dimensional engineering coordinate system as the boreholes ZK01 and ZK02. The circular disk of the borehole and the rectangular surface of the pit exploration represent the geological interface formed by the restoration of the stratum boundary in three-dimensional space. The area between the stratum interfaces is the corresponding stratum object. It can be judged whether it is the same stratum based on the position and inclination of the geological object in three-dimensional space. Fig.10 As shown, according to the conversion relationship between the pit bottom display map of pit exploration TK01 and TK02 and the three-dimensional engineering coordinate system, the exposure line of fault 1 recorded by pit exploration TK01 and TK02 is converted into the three-dimensional engineering coordinate system, and is located in the same coordinate system as the borehole ZK01, wherein the disk of the borehole is the exposure point of fault 1. Whether the fault surface morphology fitted by the fault exposure line and the exposure point is concave or convex in three-dimensional space can be determined, and whether it is the same fault can be judged in combination with the position and inclination state of the geological object in three-dimensional space.
