Description

Technical Field

[0001] This application relates to the field of geological and mineral exploration technology, and specifically discloses a method for original geological logging and mapping of solid mineral exploration. Background Technology

[0002] The primary objective of solid mineral exploration is to systematically investigate and assess underground mineral resources. In this process, original geological logging and mapping play a crucial role. This involves the collection, recording, and analysis of geological information, transforming this data into visualized geological maps. This is of great significance for understanding geological structures, predicting mineral resource distribution, and guiding subsequent exploration and development activities.

[0003] Currently, the initial geological logging and mapping of solid mineral exploration mainly relies on traditional geological survey methods, such as geological hammers, compasses, and rulers, for on-site measurement and recording. Subsequently, the data is converted into geological maps using manual drawing or computer-aided design software. However, with the continuous advancement of mineral exploration and development technologies, it has become possible to standardize geological logging data using digital and visualization technologies. Existing technologies include: methods for accurately acquiring underground logging coordinate points by controlling measuring devices via mobile terminals; methods for unified three-dimensional storage, sharing, and management of geological logging data by calculating the three-dimensional spatial coordinates of geological elements using three-dimensional digitization methods; and methods for improving the efficiency of indoor logging work by using image rendering technology to perform two-dimensional and three-dimensional calculations of geological body boundaries, morphology, and occurrence information.

[0004] While traditional manual logging and mapping methods are intuitive, they suffer from inconveniences in data organization and storage, difficulties in information sharing, and low map accuracy. Computer-aided design software, although improving drawing accuracy, often requires geologists to possess strong computer skills, resulting in low efficiency and an inability to efficiently generate geological sketches in field environments, making it difficult to guarantee the quality of data acquisition. The limitations of existing technologies are mainly reflected in three aspects: difficulties in real-time data acquisition, complexity in multi-source data fusion, and limitations imposed by fieldwork conditions. Particularly in the data processing and mapping stages, there are significant differences from the methods and procedures for processing original field data as specified in the industry standard "Specifications for Original Geological Logging of Solid Mineral Exploration" (DZ / T 0078-2015). These differences make it difficult to evaluate the standardization, validity, and quality of data, and fail to effectively generate geological logging maps that meet the standards.

[0005] This invention provides a method for original geological logging and mapping of solid mineral exploration to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of this invention is to provide a method for original geological logging and mapping of solid mineral exploration. It enables field data collection and real-time mapping through mobile devices, and combines automated tools to generate standardized geological logging maps and reports with one click, thereby improving work efficiency and reducing labor costs.

[0013] Step A5: Using the mapping tool built into the system, generate a standardized geological logging map with one click based on the collected original geological logging data.

[0014] Furthermore, the storage process includes an offline storage process, which stores the original geological logging data in a local database on a mobile device in an environment without a network connection.

[0015] Furthermore, the storage process includes an online synchronization storage process, which is a process in which the system automatically or manually synchronizes the original geological logging data in the local database to the database of the network server in a network environment.

[0016] Furthermore, during the implementation of step A1, the equipped WebGL technology is used to introduce electronic graph paper into the two-dimensional or three-dimensional visual window of the mobile device to electronically sketch and record complex geological bodies.

[0017] Furthermore, during the implementation of step A3, the geological information includes the distribution of logging points, stratigraphic boundaries, lithological boundaries, ore body boundaries, fault lines, sample location points, and the occurrence information of rock strata and boundary lines.

[0031] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0032] A method for original geological logging and mapping of solid mineral exploration, implemented as follows: Figure 1 As shown:

[0033] Includes the following steps:

[0034] Step A1: The mobile device collects geological logging data and sketch data of exploration projects such as boreholes, tunnels, and trenches according to the geological logging procedure, and preprocesses the geological logging data to obtain the raw geological logging data.

[0035] The mobile device is equipped with an Android or Windows operating system and features web-based notification visualization technologies including GeoJSON and Three.js, as well as WebGL technology. The mobile device includes tablets and smartphones.

[0036] Specifically, at the site of solid mineral exploration, staff collect geological logging data. Detailed geological logging data is collected using mobile devices according to different types of exploration projects. These exploration projects include: borehole engineering, tunnel engineering, geological profiling engineering, trenching engineering, and shallow well engineering. The geological logging data collected for different types of exploration projects are as follows:

[0037] Drilling engineering includes borehole positioning, drilling cycles, borehole inclination measurement, borehole depth, stratification, sample collection, secondary logging, hydrogeological information, final borehole measurement, and on-site photography.

[0038] Tunnel engineering includes basic tunnel information, starting point coordinates, cross-sectional specifications, baseline, logging points, stratification, sample collection, attitude measurement, and benchmark points.

[0039] Trenching engineering includes basic trench information, starting coordinates, baseline, logging points, stratification, attitude measurement, sample collection, and on-site photographs.

[0040] Geological profile engineering includes basic profile information, starting point coordinates, profile baseline, stratification boundaries, profile attitude, profile samples, logging points, etc.

[0041] Shallow well engineering includes basic information about the shallow well, coordinates of the starting point, occurrence measurement, sample collection, and logging points.

[0042] For complex ore bodies where the boundary cannot be controlled using logging points, mobile devices support manually drawing the ore body boundary shape on electronic graph paper.

[0043] During data acquisition, the system on the mobile device supports real-time verification of the completeness and standardization of geological logging data, ensuring that the collected geological logging data meets geological exploration standards and requirements. For example, the system checks whether the geological logging data is completely filled out, whether the format is correct, and whether the measurement data is within a reasonable range, thereby improving the quality of geological logging data.

[0044] The collected geological logging data is then preprocessed by the system on the mobile device to obtain the raw geological logging data. The preprocessing steps include verifying the geological logging data. If the verification fails, the raw geological logging data is collected again. If the verification passes, the next step is performed.

[0045] Step A2: Classify the raw geological logging data according to different types and store them in the database of the mobile device.

[0046] Specifically, stored procedures include offline stored procedures and online synchronous stored procedures.

[0047] Offline storage process: Raw geological logging data is stored in a local database on a mobile device in environments without network access. This ensures that data acquisition is not limited by network connectivity, allowing geologists to complete data collection and preliminary processing in the field.

[0048] Online synchronization storage process: In a network environment, the system automatically or manually synchronizes the original geological logging data from the local database to the database on the network server. This synchronization mechanism ensures data integrity and consistency, while facilitating subsequent data processing and analysis.

[0049] Step A3: The system on the mobile device calls the original geological logging data in the local database of the mobile device and realizes the offline two-dimensional or three-dimensional visualization of geological information according to the mapping rules of geological bodies.

[0050] The geological information includes the distribution of logging points, stratigraphic boundaries, fault lines, sample locations, and other relevant geological information.

[0051] Furthermore, in this embodiment, the system also utilizes WebGL technology to introduce electronic graph paper into a two-dimensional or three-dimensional visual window on the mobile device, allowing geologists to electronically sketch and record complex geological bodies. This approach not only improves the efficiency of mapping but also enhances the intuitiveness and accuracy of geological information, facilitating geologists to view and analyze geological structures in real time in the field.

[0052] Step A4: The system on the mobile device integrates, analyzes, and interprets the geological points, lines, samples, and attitude information collected by the mobile device with the sketch data to generate a geological model.

[0053] Specifically, the system integrates and interprets geological information collected from mobile devices (such as logging points and stratigraphic boundaries) with sketch data. By matching geological entity data such as points, lines, and surfaces with corresponding geological business attributes (such as fault line locations and attitude information), a more complete and accurate geological model is generated. This process not only improves the utilization value of the data but also provides richer information support for subsequent mapping and report generation.

[0054] Step A5: Using the mapping tool built into the system, generate a standardized geological logging map with one click based on the collected original geological logging data.

[0055] Specifically, the one-click image creation process includes the following steps:

[0056] Data loading: Retrieves raw geological logging data that has undergone fusion processing from a local database or web server.

[0057] Automated drawing: Based on preset drawing rules and geological logging procedures, automatically draw geological maps such as borehole columnar sections, tunnel sketches, trench sketches, measured geological profiles, and shallow well sketches.

[0058] Standardized output: Generates geological maps that meet national standards and supports export in multiple formats (such as DWG, Mapgis, PDF, PNG, etc.) to meet the needs of subsequent geological data acceptance, 3D modeling, and report preparation.

[0059] like Figure 2 and Figure 3 As shown, Figure 2 This diagram illustrates real-time offline field mapping via a mobile device. Figure 3 The image shows a standardized tunnel sketch generated with a single click using a mapping tool. Figure 2 and Figure 3 The grid lines shown are electronic MiG lines.

[0060] In this embodiment, the one-click image generation function relies on several key technologies, as detailed below:

[0061] Data processing and fusion: Multi-source data fusion: Integrating multi-source data such as boreholes, tunnels, trenches, and geological profiles, and ensuring data consistency and integrity through data cleaning and formatting.

[0062] Attribute matching and updating: Automatically identify the attribute information of geological elements (such as strata, lithology, ore bodies, faults, occurrence, and sample points) and perform integration and updating.

[0063] Automated drawing engine: Rule engine: Based on geological logging procedures, a rule engine is developed to define drawing rules for elements such as strata, lithology, ore bodies, faults, and samples.

[0064] Symbol library and templates: Built-in national standard lithology pattern library, supporting intelligent filling and personalized customization to meet the drawing needs of different geological maps.

[0065] Automated drawing: By calling the drawing engine through a programming interface (such as a Python script or GIS tool), batch automatic drawing of maps can be achieved using "data + template".

[0066] Intelligent Algorithm: Geological Element Integration: Intelligent algorithms are used to automatically merge and simplify geological bodies, identify overburden relationships, and screen and process small geological bodies.

[0067] Intelligent labeling and rendering: Automatically identifies geological codes, faults, attitudes and other elements, and performs intelligent labeling and color rendering.

[0068] System Integration and Optimization: Multi-platform Support: The one-click image generation tool supports multiple operating systems such as Windows and Linux, ensuring system versatility.

[0069] Performance optimization: Improve system response speed and drawing efficiency by optimizing data processing flow and rendering algorithms.

[0070] User Interaction and Extensibility: Simple and Easy-to-Use Interface: Provides a simple and intuitive operation interface. Users only need to organize the raw data according to the template to generate the map with one click.

[0071] Supports customization and expansion: Users can customize symbol libraries and drawing templates according to their actual needs, and support unlimited expansion.

[0072] Step A6: The system retrieves data from the network server database and, in conjunction with the geological logging procedures, automatically generates geological reports and forms.

[0073] The reports and forms include, but are not limited to, summaries of geological exploration results, data analysis results, charts, and other content. The automatic report generation function not only saves a significant amount of manual writing time but also improves the accuracy and consistency of reports, providing strong support for the management and decision-making of geological exploration projects.

[0074] This invention, through the combination of mobile devices, database technology, graphical visualization technology, and a one-click mapping tool, achieves full automation and intelligence across the entire process from raw geological logging data acquisition, storage, and processing to mapping and report generation. It breaks through the inefficient model of traditional geological exploration that relies on manual operation, significantly improving work efficiency and data quality.

[0075] This invention places particular emphasis on the application of mobile devices, utilizing GeoJSON, Three.js, and WebGL technologies to achieve offline two-dimensional and three-dimensional visualization of geological information and electronic sketching records. Geologists can view the mapping results in real time in field environments without internet access. This feature greatly improves the flexibility and efficiency of fieldwork while enhancing the intuitiveness of geological information.

[0076] This invention not only collects and stores geological logging data, but also integrates and processes the data through intelligent algorithms. For example, it automatically identifies geological elements (such as stratigraphic boundaries and fault lines), performs intelligent annotation, and comprehensively processes geological bodies. These functions reduce manual operation, avoid errors caused by human factors, and simultaneously improve the utilization value of the data and the accuracy of the maps.

[0077] This invention utilizes an automated drawing engine and a rule engine, enabling the system to quickly generate standardized geological logging maps based on preset geological logging procedures and drawing rules. This function not only improves mapping efficiency but also ensures the standardization and consistency of the maps, meeting industry standards.

[0078] This invention supports the fusion processing of multi-source data, including different types of data such as borehole, tunnel, trench, and geological profile. Simultaneously, the system is compatible with multiple operating systems (such as Windows and Linux) and devices (such as mobile devices and desktops), ensuring the universality and applicability of the technical solution.

[0079] In addition to mapping capabilities, this invention also features the ability to automatically generate reports and charts. By accessing data from a web server database and combining it with geological logging procedures, the system quickly generates geological exploration reports and related charts. This function further reduces the time and workload of manual report writing, improving work efficiency.

[0080] This invention deeply integrates advanced computer technologies (such as mobile devices, WebGL, Three.js, and artificial intelligence) with traditional geological exploration work, promoting the digital transformation of the geological exploration industry. Through technological innovation, this invention provides an efficient, accurate, and convenient technical solution for solid mineral exploration, possessing significant industry application value and promising prospects for widespread adoption.

[0081] This invention, through an innovative technical solution for original geological logging and mapping in solid mineral exploration, achieves full-process automation and intelligence, significantly improving the efficiency, accuracy, and quality of geological exploration work while reducing labor intensity and costs. Compared with traditional methods, this invention utilizes mobile devices, automated mapping tools, and intelligent algorithms to drastically shorten data acquisition, processing, and mapping time, increasing efficiency by over 30%. Through data fusion, intelligent annotation, and 3D visualization technologies, it significantly improves data accuracy and mapping quality. Simultaneously, it reduces reliance on professional drafting personnel, lowering labor costs and intensity. Furthermore, this invention promotes the digital transformation of the geological exploration industry, fosters multidisciplinary collaboration, and possesses significant industry application value and promising prospects for wider application.
