Abstract
Description
Technical Field
[0001] The invention relates to the technical field of coal resource exploration, in particular to a device for delineating coal resources for coking. Background Art
[0002] In the coking industry, the quality and characteristics of coal resources play a vital role in the output and quality of coking products. However, due to the complex distribution of coal resources and the significant differences in coal seam thickness, physical properties, and chemical composition, how to accurately and efficiently identify coal resources suitable for coking technology has always been a difficult problem to be solved in the industry. At present, the existing technologies have the following deficiencies:
[0003] 1. Low sampling efficiency and poor representativeness. In the existing technology, coal sampling mostly relies on manual or semi-automatic equipment. In the complex coal mine environment, manual sampling is inefficient and has large errors, and cannot cover the diversity of the entire coal seam. The selection of sampling points is often based on experience and lacks accurate geological exploration information, which leads to insufficient representativeness of the sampling results, thus affecting the comprehensive assessment of coal resources. In addition, the manual sampling process is time-consuming and costly, and there are safety hazards in deep wells and dangerous terrain conditions;
[0004] 2. Single detection means and low analysis accuracy. Traditional coal resource delineation methods mainly rely on physical property detection, such as coal seam thickness and density. However, a single physical detection method is difficult to fully reflect the coking suitability of coal, because the coking process not only depends on the physical structure of coal, but also is affected by the chemical composition of coal (such as sulfur content, volatile matter, ash, etc.). Therefore, due to the single detection means in the existing technology, it is impossible to accurately evaluate the coking suitability of coal, which leads to insufficient resource utilization and even wrong decisions;
[0005] 3. Lack of data integration and intelligent analysis. Existing technologies are relatively backward in data processing and analysis capabilities. Usually, physical detection and chemical analysis results cannot be integrated on a unified platform for comprehensive evaluation, resulting in the judgment of coal coking suitability relying on human experience and lack of systematic and intelligent analysis methods. At the same time, existing technologies rarely use modern algorithms such as machine learning to learn and optimize historical data, resulting in low data utilization efficiency and difficulty in coping with complex and dynamic changes in coal characteristics;
[0006] 4. Lack of a suitability scoring model. Most of the suitability evaluation methods in the existing technology are based on a single indicator or empirical formula, which is difficult to accurately reflect the actual coking performance of coal. Different coal seams may perform well in certain indicators, but are not suitable for coking when considered comprehensively. The lack of a comprehensive scoring model to quantify the suitability of coal makes the accuracy of delineating coal resources for coking low, resulting in a reduction in the effectiveness of coal mine resource development decisions;
[0007] 5. Lack of automated delineation and decision-making support tools. In the existing coal resource delineation process, the delineation of coal suitability basically relies on manual analysis and manually drawn resource distribution maps. There is a lack of automated delineation tools, which not only consumes a lot of manpower and material resources, but is also prone to omissions or errors. Decision makers lack scientific and reliable data support when making resource utilization plans, and it is difficult to effectively evaluate the development priorities of different coal seams, resulting in insufficient or inaccurate decisions. Summary of the invention
[0008] In order to solve the problem of the current equipment used for coking coal resource delineation in the market, a scoring model that integrates physical and chemical properties is used to quantify the coking suitability of coal, solving the problem that traditional technology cannot accurately reflect the coking performance of coal. The scoring model takes into account multiple key characteristics of coal and adapts to different coal seam characteristics by adjusting the weight coefficient, providing a more scientific applicability scoring method, thereby improving the accuracy of resource delineation.
[0009] To achieve the above-mentioned purpose, the first embodiment of the present application proposes a device for delineating coal resources for coking, comprising an assembly base, the top of which is fixedly connected to a support frame, and a coal sampling system for automatically collecting coal samples from a coal seam, wherein the sampling system comprises a robotic arm, drilling equipment, a sensor and a real-time monitoring module for ensuring the accuracy of the sampling position and the representativeness of the coal sample; a physical parameter detection module for detecting the physical properties of the sampled coal, including but not limited to the density, acoustic wave propagation velocity and resistivity of the coal, and the module can provide real-time feedback on the hardness, internal structure and hierarchical distribution information of the coal; a chemical analysis module, including equipment such as a gas chromatograph and an X-ray fluorescence spectrometer, for analyzing key chemical parameters of the coal such as volatile matter, sulfur content, ash content, calorific value, etc.; a data processing unit for receiving data from the physical parameter detection module and the chemical analysis module, and generating a coal coking suitability score based on the physical and chemical properties of the coal; a suitability delineation algorithm module, which uses the coal suitability score to delineate coal resource areas through an algorithm, and coal resources suitable for coking will be marked for further utilization.
[0010] The device for delineating coking coal resources in the embodiment of the present application solves the problems of low sampling efficiency, single detection means, inaccurate applicability assessment, and high manual dependence in the delineation process in the prior art through technical means such as automated sampling, multi-dimensional detection, intelligent scoring and delineation.

The model can also be adaptively adjusted according to the geology and resource distribution of different coal mines to adapt to the coal characteristics under different environments.

BRIEF DESCRIPTION OF THE DRAWINGS
[0028] Figure 1 The present invention is a flow chart of the device for delineating coal resources for coking. DETAILED DESCRIPTION
[0029] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.
[0030] The following describes the device for delineating coking coal resources according to an embodiment of the present application in conjunction with the accompanying drawings.
[0031] The present application provides a device for delineating coal resources for coking, which quantifies the coking suitability of coal through a scoring model that integrates physical and chemical properties, solving the problem that traditional technologies cannot accurately reflect the coking performance of coal. The scoring model takes into account multiple key characteristics of coal, and adapts to different coal seam characteristics by adjusting weight coefficients, providing a more scientific applicability scoring method, thereby improving the accuracy of resource delineation.
[0032] like Figure 1 As shown, the device for delineating coal resources for coking in the embodiment of the present application may include a coal sampling system for automatically collecting coal samples from coal seams, the sampling system including a robotic arm, drilling equipment, sensors and a real-time monitoring module for ensuring the accuracy of the sampling position and the representativeness of the coal sample, a physical parameter detection module for detecting the physical properties of the sampled coal, including but not limited to the density, acoustic wave propagation velocity and resistivity of the coal, the module being able to provide real-time feedback on the hardness, internal structure and hierarchical distribution information of the coal, a chemical analysis module including equipment such as a gas chromatograph and an X-ray fluorescence spectrometer for analyzing key chemical parameters of the coal such as volatile matter, sulfur content, ash content and calorific value, a data processing unit for receiving data from the physical parameter detection module and the chemical analysis module, generating a coal coking suitability score based on the physical and chemical properties of the coal, and a suitability delineation algorithm module for delineating coal resource areas through an algorithm using the coal suitability score, and coal resources suitable for coking will be marked for further use.
[0033] It should be noted that the device described in this embodiment can accurately sample coal seams through the cooperation of a mechanical arm, drilling equipment, sensors and real-time monitoring modules. Traditional technologies often rely on manual sampling, which is not only inefficient but also inaccurate, especially in complex terrain and when the structure of coal seams changes frequently, it is difficult to ensure the representativeness of the samples. The present device improves the collection accuracy of coal samples through intelligent sampling planning and automatic monitoring. In traditional coal sampling methods, representative samples in coal seams are difficult to obtain due to manual operation and equipment limitations. The present device realizes automatic sampling through a mechanical arm combined with drilling equipment, and the sensors and monitoring modules provide real-time feedback, which can adjust the sampling strategy at any time according to the geological conditions on site. This greatly improves the sampling efficiency and accuracy, especially for areas with complex coal seam distribution. In addition, the close integration of the physical detection module and the chemical analysis module enables the device to not only collect samples, but also perform detailed analysis of the samples.
[0034] Furthermore, if Figure 1 As shown, the coal sampling system has an automatic path planning function, which can adaptively adjust the sampling path based on the geological map and coal seam structure information to ensure the uniformity and comprehensiveness of the sampling. The system can also adjust the sampling frequency according to different geological conditions to ensure the sampling efficiency in complex geological environments.
[0035] It should be noted that the path planning function described in this embodiment. Traditional coal sampling often lacks systematic path planning, and it is easy to have problems such as repeated sampling or missing certain key areas during the sampling process. By introducing the automatic path planning function, this device can adaptively adjust the sampling path according to the actual geological conditions to ensure the uniformity and comprehensiveness of the sampling. Especially in the development of large-scale coal mines, this function is particularly important. Through path planning, the device can design the optimal sampling route according to the distribution characteristics and structural changes of the coal seam, avoiding the blindness in human operation. The system can also monitor the changes in geological conditions in real time and dynamically adjust the sampling frequency to ensure efficient work in complex geological environments. In addition, this function can also reduce the occurrence of repeated sampling, saving time and cost. This function of adaptively adjusting the sampling path not only improves the evaluation efficiency of coal resources, but also ensures the accuracy of the evaluation results.
[0036] The physical parameter detection module includes an acoustic wave attenuation detection unit and a resistivity measurement unit. The internal structure of the coal is evaluated by detecting the acoustic wave attenuation of the coal seam, and the conductivity and moisture content of the coal are evaluated by the change of resistivity, and the physical suitability index of the coal is calculated.
[0037] It should be noted that the comprehensive evaluation of the physical properties of coal by acoustic wave attenuation and resistivity measurement described in this embodiment. Traditional physical detection methods are usually limited to the measurement of a single parameter, while the present invention adopts a combination of multiple physical parameter detection methods to ensure the comprehensiveness of the data. Acoustic wave attenuation can effectively reflect the internal structure of coal, especially when detecting the thickness distribution and hardness of coal seams. Resistivity measurement can reveal the conductivity and water content information of coal, thereby providing a more reliable data basis for subsequent applicability analysis. Through the dual detection of acoustic wave attenuation and resistivity, this device can more accurately evaluate the applicability of coal from a physical perspective. Especially in the case of complex coal seam structure or changeable coal physical properties, a single detection method often cannot provide sufficient information support, and this multi-dimensional detection method can make up for this defect. Combined with real-time feedback and data processing units, the physical parameter detection module can significantly improve the screening and evaluation efficiency of coking coal.
[0038] The chemical analysis module has an online real-time monitoring function, which can automatically analyze the ash content, sulfur content, volatile matter and calorific value of the collected samples, and automatically generate the coking suitability evaluation of the coal through the algorithm. The module can also connect to the database through the cloud platform and automatically compare historical data, thereby improving the accuracy and reliability of the analysis results.
[0039] It should be noted that the traditional chemical analysis described in this embodiment often relies on laboratory analysis, which is not only time-consuming but also has delayed analysis results, and cannot guide the development of coal resources in a timely manner. The chemical analysis module in this device can generate a coking applicability evaluation in a timely manner by real-time monitoring of chemical indicators such as volatile matter, ash, sulfur content, calorific value, etc. of coal samples, providing support for the efficient use of coal. The chemical analysis module is also connected to the database through a cloud platform, and can be compared with historical data to further improve the accuracy of the analysis results. This method of real-time data processing and historical data comparison significantly improves the reliability of the analysis, especially when the coal composition changes greatly. The real-time monitoring function can effectively capture these changes and make corresponding adjustments, avoiding the misjudgment caused by data lag in traditional methods. Online monitoring and automatic generation of applicability reports not only speed up the speed of resource assessment, but also provide timely decision support for subsequent coal mine development.
[0040] The data processing unit analyzes the physical and chemical data based on a multivariate linear regression model or a machine learning algorithm and automatically adjusts the weight coefficients in the model. The calculation formula for the coking suitability score (S) is as follows: S = α1·P h +α2·A s +α3·T v Among them, P h Indicates the physical properties of coal, A s Indicates the ash content of coal, T v It represents the calorific value of coal, and α1, α2 and α3 are weighting coefficients.
[0041] It should be noted that the coking suitability scoring model of the data processing unit described in this embodiment is clearly proposed, and a specific calculation formula is given. The model is based on a multiple linear regression algorithm, combining physical and chemical data to derive a comprehensive suitability score S. The score can accurately reflect the performance of coal in the coking process and provide a quantitative basis for the efficient use of coal. The weighting coefficients α1, α2 and α3 in the formula can be adjusted according to different coal mine conditions, making the scoring model highly adaptable. This data-based automated analysis greatly improves the accuracy of coal resource assessment and avoids the deviation caused by subjective judgment in traditional assessment methods. In addition, the scoring model can also be iteratively optimized based on continuously collected data, so that its evaluation results are more in line with actual application needs.
[0042] The multivariate linear regression model is based on a large amount of actual sampling data, and the optimal weight parameters are obtained through iterative training to improve the accuracy of the suitability score. The model can also be adaptively adjusted according to the geology and resource distribution of different coal mines to adapt to the coal characteristics under different environments.
[0043] It should be noted that the machine learning algorithm described in this embodiment can train a large amount of historical data, thereby optimizing the weighting coefficient of the scoring model, and finally deriving the applicability scoring standard that best suits the current coal mine conditions. The scoring methods in the prior art are usually fixed and difficult to adapt to the conditions of different coal mines. This model can tailor the scoring standards for each specific coal mine through the adaptive adjustment function. Through the accumulation and analysis of a large amount of data, the prediction accuracy of the model will be improved, thereby providing more forward-looking guidance for future coal resource development. This adaptive model based on machine learning not only improves the scientific nature of the evaluation, but also can adjust the scoring algorithm according to different environmental conditions, making it widely applicable.
[0044] The suitability delineation algorithm module can automatically generate a coal resource map based on the coking suitability score of coal, which identifies the distribution of coal resources suitable for coking in different regions and provides the utilization priority of coal in different regions. The delineation algorithm module can also predict future resource development based on historical data.
[0045] It should be noted that the embodiment describes the identification of coal resources suitable for coking in different areas. This mapping visualization tool greatly facilitates the development and management of coal mines, allowing them to see at a glance which areas of coal resources are most suitable for coking, thereby giving priority to development. In addition, the delineation algorithm module also has a prediction function, which can make predictions about future resource development based on historical data and current evaluation results. Compared with traditional manual evaluation methods, this algorithm-based delineation and prediction is not only faster, but also more accurate, providing more scientific decision-making support for coal mine development.
[0046] The coal sampling system described above can automatically detect environmental parameters such as temperature, humidity, and pressure in the sampling area in combination with geological conditions, and can correct the sampling results based on these environmental parameters. The sampling system can also operate flexibly in complex terrain, including automatically adjusting the mechanical arm angle and drilling depth to ensure sampling accuracy in rugged terrain or steep coal seams.
[0047] It should be noted that the sampling system described in this embodiment can be dynamically adjusted according to actual environmental parameters such as temperature, humidity and pressure to ensure the accuracy of the sampling results. Traditional sampling systems usually ignore the influence of environmental conditions, resulting in large deviations in sampling results, while this device improves the accuracy of sampling by correcting environmental parameters. This sampling method is particularly suitable for coal mine development in complex terrain or extreme climatic conditions. By automatically adjusting the angle of the robotic arm and the drilling depth, the system can maintain efficient operation in rugged terrain, ensuring the accuracy and representativeness of the sampling results.
[0048] The physical parameter detection module also includes a radar device for detecting the thickness of the coal seam, which can accurately measure the thickness changes of the coal seam and evaluate the uniformity of the coal seam in combination with the resistivity and sound wave attenuation data, so as to better judge the physical suitability of the coal.
[0049] It should be noted that the traditional coal seam thickness detection method described in this embodiment usually relies on a single physical method, which is difficult to accurately reflect the actual thickness changes of complex coal seams. This device can better evaluate the uniformity and thickness distribution of coal seams through radar measurement combined with resistivity and acoustic wave data. This multi-dimensional detection method can significantly improve the evaluation accuracy of coal physical properties and provide reliable data support for subsequent coking suitability analysis. Especially in the case of complex coal seam structures and large thickness variations, the application of this multiple detection method is extremely advantageous.
[0050] The chemical analysis module also includes an analysis unit for detecting rare elements in coal (such as uranium, thorium, etc.). The unit can identify trace elements present in coal and analyze the content of these elements to ensure the safety and environmental protection of coal, especially to avoid the production of harmful substances during the coking process.
[0051] It should be noted that the function of the chemical analysis module described in this embodiment specifically adds the detection of rare elements (such as uranium, thorium, etc.) in coal. Traditional coal chemical analysis often only focuses on conventional components and ignores the presence of rare elements. This device ensures the safety and environmental protection of coal during the coking process by detecting these rare elements. This design is particularly suitable for areas with high requirements for coal environmental protection. It can effectively avoid the production of harmful substances during the coking process and ensure the clean use of coal. In addition, the analysis of rare elements can also provide new ideas for the further development and utilization of resources.
[0052] Specifically, the introduction of an automated coal sampling system and path planning function makes the sampling process more efficient and suitable for complex geological environments, reducing human errors. The physical and chemical parameters are combined for analysis. Through a comprehensive scoring system of physical and chemical properties, the coking suitability of coal can be more accurately evaluated. The suitability scoring model is optimized through a machine learning algorithm, making the scoring results more accurate and adaptively adjusted based on historical data, significantly improving the accuracy of suitability judgment. The suitability delineation algorithm can directly generate resource distribution maps and utilization priorities, providing decision-making support tools for coal mine development and greatly improving decision-making efficiency.
