Description

Technical Field

[0001] This invention relates to the field of risk warning technology, and in particular to a coal mining risk warning system based on data processing. Background Technology

[0002] In the field of coal mining, existing risk warning systems mainly rely on manual monitoring and simple data analysis. They typically collect only limited geological and environmental data, such as rock strata stability and gas concentration, and make simple threshold judgments based on this data.

[0003] Chinese patent application publication number CN118378785A discloses a real-time risk detection system for coal mining based on data analysis, including a coal mine supervision platform, a mine tunnel risk monitoring module, a roof inspection module, a mining equipment operation and monitoring module, and a coal mine remote management terminal. This invention uses the mine tunnel risk monitoring module to detect safety hazards within the mine tunnel in real time, achieving multi-point comprehensive monitoring and assessment of safety hazards within the mine tunnel. The roof inspection module reasonably assesses roof risks and provides timely early warning feedback. The mining equipment operation and monitoring module analyzes the operating status of the corresponding mining equipment. The personnel safety assessment module generates personnel safety signals or personnel risk signals through vital sign safety monitoring and analysis.

[0004] In existing technologies, if the system's processing speed is not fast enough during the process of collecting and analyzing monitoring data to issuing early warning signals, there may be a problem of early warning delay, resulting in low accuracy of early warning for coal mine safety. Summary of the Invention

[0035] Wherein, the first preset proportion is greater than the second preset proportion.

[0036] Furthermore, the strategy generation unit includes:

[0039] A frequency adjustment subunit is used to adjust the preset frequency when the actual proportion is less than the second preset proportion.

[0040] Furthermore, the division adjustment subunit includes:

[0041] A marked block is used to mark several mining points that are less than the preset mining safety among the actual mining safety, thereby obtaining marked points;

[0042] Adjust the block and connect it to the marked block to adjust the preset ratio corresponding to the marked point, so as to adjust the preset division standard.

[0043] Furthermore, the frequency adjustment subunit includes:

[0044] A deviation calculation block is used to calculate the deviation between the actual proportion and the second preset proportion;

[0045] A frequency adjustment block, connected to the deviation calculation block, is used to adjust the preset frequency based on the deviation.

[0046] Compared with existing technologies, the beneficial effects of this invention are as follows: by setting the division module to meticulously divide the mining area based on preset division criteria, it helps to make subsequent data collection and risk assessment more targeted, improving the accuracy and efficiency of the early warning system.

The strategy generation module intelligently triggers alarms, adjusts preset division criteria, or adjusts preset frequencies based on the comparison results of the actual mining safety of each mining point with the preset safety, making timely and effective responses according to different risk situations and reducing safety risks in the mining process.

[0047] In particular, the standard determination unit can accurately identify the edge contour of the area to be mined, providing a basis for subsequent division and ensuring the accuracy and relevance of the division. By reducing the edge contour by a preset ratio, the division results are more uniform and adapted to the actual area to be mined, facilitating subsequent data collection and risk assessment, and improving the applicability of the division. The division unit can accurately divide the area to be mined according to the standard grid, which helps to improve the detail of subsequent data collection and risk assessment, and improves the accuracy of the early warning system. Through the grid-based division method, the location of the mining points is clearer and more specific, which facilitates subsequent data collection, risk assessment and strategy generation, thereby improving the accuracy of the early warning system.

[0048] In particular, by setting up the geological safety calculation unit to comprehensively consider multiple geological factors such as real-time soil softness and real-time groundwater pressure, a multi-dimensional geological safety assessment is conducted, which helps to more accurately identify potential geological risks. By comparing real-time data with preset values, geological safety indicators are calculated in real time, ensuring the timeliness and accuracy of risk assessment. The environmental safety calculation unit comprehensively considers environmental factors such as real-time gas concentration and real-time dust concentration to conduct environmental safety assessment, which helps to more accurately identify potential environmental risks.

[0058] The division module 10 is used to determine the area to be mined. Based on the preset division criteria, the area to be mined is divided to obtain several mining points.

[0059] The data acquisition module 20 is connected to the division module 10 and is used to collect several real-time geological data and several real-time environmental data corresponding to several mining points based on a preset frequency.

[0060] The data processing module 30 is connected to the data acquisition module 20 and is used to calculate the geological safety based on several real-time geological data corresponding to any mining point, calculate the environmental mining safety based on several real-time environmental data corresponding to any mining point, and calculate the actual mining safety corresponding to any mining point based on the geological safety, environmental mining safety and preset weights.

[0061] The strategy generation module 40 is connected to the data processing module 30 and is used to issue an alarm based on the comparison results of the actual mining safety and preset safety of several mining points, or to adjust the preset division standard, or to adjust the preset frequency.

[0062] The real-time geological data includes real-time soil softness and real-time groundwater pressure, and the real-time environmental data includes real-time gas concentration and real-time dust concentration.

[0063] Specifically, the preset frequency described in this embodiment of the invention is 30 min / time.

[0064] Specifically, the real-time soil looseness, real-time groundwater pressure, real-time gas concentration and real-time dust concentration described in the embodiments of the present invention can be collected by their corresponding sensors. For example, real-time groundwater pressure can be collected by a water pressure sensor or by other technical means, which are existing technologies and will not be described in detail here.

[0065] Specifically, this embodiment of the invention, by setting the division module to meticulously divide the mining area based on preset division criteria, facilitates targeted data collection and risk assessment, improving the accuracy and efficiency of the early warning system. By setting the data collection module to collect real-time geological and environmental data of each mining point at a preset frequency, the timeliness and accuracy of the data are ensured, providing a reliable foundation for risk assessment.

[0066] See Figure 2 As shown, the partitioning module 10 includes:

[0067] The standard determination unit 11 is used to identify the edge contour of the area to be mined, and to reduce the edge contour by a preset ratio to obtain a standard division grid.

[0068] The division unit 12 is connected to the standard determination unit 11 and is used to divide the area to be mined according to the standard division grid to obtain several division areas as the mining points.

[0069] Specifically, the preset ratio described in this embodiment of the invention is 1:5.

[0070] Specifically, the standard determination unit in this embodiment of the invention can accurately identify the edge contour of the area to be mined, providing a basis for subsequent division and ensuring the accuracy and relevance of the division. By reducing the edge contour by a preset ratio, the division results are more uniform and adapted to the actual area to be mined, facilitating subsequent data collection and risk assessment, and improving the applicability of the division. The division unit can accurately divide the area to be mined according to the standard grid, which helps to improve the detail of subsequent data collection and risk assessment, and improves the accuracy of the early warning system. Through the gridded division method, the location of the mining points is clearer and more specific, facilitating subsequent data collection, risk assessment and strategy generation, thereby improving the accuracy of the early warning system.

[0071] See Figure 3 As shown, the data processing module 30 includes:

[0072] The geological safety calculation unit 31 is used to compare several real-time soil softness values ​​with preset soil softness values, compare several real-time groundwater pressure values ​​with preset groundwater pressure ranges, and calculate the geological safety based on the comparison results.

[0073] The environmental safety calculation unit 32 is used to compare several real-time gas concentrations with preset gas concentrations and several real-time dust concentrations with preset dust concentrations, and calculate the environmental safety based on the comparison results.

[0074] The weight determination unit 33 is used to determine the preset weight based on the comparison result of the geological safety and the environmental safety;

[0075] The safety acquisition unit 34 is connected to the geological safety judgment unit 31, the environmental safety judgment unit 32 and the weight determination unit 33, and is used to obtain the actual mining safety based on the geological safety, the environmental safety and the preset weight.

[0076] Specifically, this embodiment of the invention, by setting up a geological safety calculation unit, comprehensively considers multiple geological factors such as real-time soil softness and real-time groundwater pressure to conduct a multi-dimensional geological safety assessment, which helps to more accurately identify potential geological risks. By comparing real-time data with preset values, geological safety indicators are calculated in real time, ensuring the timeliness and accuracy of risk assessment. The environmental safety calculation unit comprehensively considers environmental factors such as real-time gas concentration and real-time dust concentration to conduct an environmental safety assessment, which helps to more accurately identify potential environmental risks. By monitoring and comparing the differences between gas concentration and dust concentration and preset values ​​in real time, changes in environmental risks are captured, and environmental safety indicators are accurately calculated. The weight determination unit dynamically adjusts the preset weights based on the comparison results of geological safety and environmental safety, making risk assessment more flexible and accurate, adaptable to changes in different mining conditions and risk situations, and improving the accuracy and comprehensiveness of overall risk assessment. The safety acquisition unit comprehensively calculates the actual mining safety based on geological safety, environmental safety, and preset weights, providing more comprehensive risk information, helping to formulate more effective preventive measures, and improving decision-making efficiency and accuracy.

[0077] Specifically, the geological safety calculation unit includes:

[0078] The first calculation subunit is used to calculate the proportion of the real-time soil softness that is less than the preset soil softness, and to determine the collapse safety based on the proportion result.

[0079] The second calculation subunit is used to calculate the proportion of the real-time groundwater pressures that do not fall within the preset groundwater pressure range, and to determine the water pressure safety based on the proportion results.

[0080] A geological safety calculation subunit, connected to the first calculation subunit and the second calculation subunit, is used to calculate the geological safety based on the collapse safety and the water pressure safety.

[0081] It is understandable that a safe soil looseness may be set below a certain value. Exceeding this value may indicate that the soil is too loose and there is a risk of collapse. The specific value of the preset soil looseness needs to be determined according to the actual situation of each coal mine, and may be adjusted as mining progresses and geological conditions change. One indicator of soil looseness can be represented by a firmness coefficient. The value of the firmness coefficient ranges from 0 to 1. The calculation formula of the firmness coefficient is existing technology and will not be elaborated here. In this embodiment of the invention, the preset soil looseness can be set to 0.5.

[0082] It is understood that the preset groundwater pressure range described in this embodiment of the invention is determined by historically detected groundwater pressure. The minimum and maximum values ​​among several historically detected groundwater pressures are used as the preset groundwater pressure range. If the pressure is not within the preset groundwater pressure range, it may lead to problems such as mine water inrush or failure of the supporting structure.

[0083] It is understood that the geological safety described in the embodiments of the present invention is the product of the collapse safety and the water pressure safety.

[0084] Specifically, the environmental safety judgment unit includes:

[0085] A gas safety calculation subunit is used to calculate the proportion of several real-time gas concentrations that are greater than or equal to the preset gas concentration, and to determine the gas safety based on the proportion result.

[0086] The dust safety calculation subunit is used to calculate the proportion of the real-time dust concentrations that are greater than or equal to the preset dust concentration, and to determine the dust safety based on the proportion result.

[0087] An environmental safety calculation subunit is connected to the gas safety calculation subunit and the dust safety calculation subunit to calculate the environmental safety based on the gas safety and the dust safety.

[0088] It is understood that, under normal circumstances, the methane concentration in coal mines should be controlled below 1%. When the methane concentration reaches 5% to 15%, it may cause an explosion when exposed to a source of ignition. The preset methane concentration in this embodiment of the invention is 1%.

[0089] It is understood that, according to the MT / T1171—2019 standard, there are specific limits on the total dust concentration and respirable dust concentration in coal mines in this embodiment of the invention. For example, the limit for total dust concentration may be 10 mg / m³ (10 milligrams per cubic meter), while the limit for respirable dust concentration may be 5 mg / m³. The preset dust concentration in this embodiment of the invention is 5 mg / m³.

[0090] It is understood that the environmental safety described in the embodiments of the present invention is the product of the gas safety and the dust safety.

[0091] Specifically, the weight determination unit includes:

[0092] The safety comparison subunit is used to compare the geological safety and the environmental safety to obtain a safety comparison result;

[0093] The weight calculation subunit is connected to the security comparison subunit to determine the weight allocation ratio based on the security comparison result, thereby determining the preset weight.

[0094] It is understood that, in the embodiments of the present invention, determining the weight allocation ratio based on the safety comparison result may include, when the geological safety is greater than the environmental safety, the weight corresponding to the geological safety is greater than the weight corresponding to the environmental safety, and the sum of the weights is 1. For example, the weight corresponding to the geological safety is 60%, and the weight corresponding to the environmental safety is 40%. When the geological safety is less than the environmental safety, the weight corresponding to the geological safety is less than the weight corresponding to the environmental safety, and the sum of the weights is 1. For example, the weight corresponding to the geological safety is 40%, and the weight corresponding to the environmental safety is 60%.

[0095] See Figure 4 As shown, the strategy generation module 40 includes:

[0096] Safety comparison unit 41 is used to compare the actual mining safety with the preset mining safety to obtain a safety comparison result;

[0097] The percentage calculation unit 42 is connected to the safety comparison unit 41 and is used to calculate the actual percentage of the actual mining safety being less than the preset mining safety.

[0098] The strategy generation unit 43 is connected to the proportion calculation unit 42 and is used to determine whether to trigger an alarm, adjust the preset division standard, or adjust the preset frequency based on the comparison result between the actual proportion and the first preset proportion and the second preset proportion.

[0099] Wherein, the first preset proportion is greater than the second preset proportion.

[0100] It is understood that the preset mining safety described in the embodiments of the present invention can be set based on historical data of coal mining, determining the mining safety corresponding to the historical mining safety, and judging the average value of several historical mining safety as the preset mining safety. In the embodiments of the present invention, the preset mining safety can be set as a percentage value, for example, several historical mining safety values ​​are 92%, 95%, and 97%, respectively, and the preset mining safety is calculated to be approximately %, which means that the actual mining safety should be maintained above 95% to ensure the safety of the mining process.

[0101] It is understood that the setting of the first preset percentage and the second preset percentage in the embodiments of the present invention is based on the analysis of past safety accidents and early warning responses in the mine. Two percentage thresholds can be determined. For example, if historical data shows that when more than 20% of the mining points are below the safety standard, the probability of a safety accident increases significantly, then the first preset percentage can be set to 20%. When less than 5% of the mining points are below the safety standard, the probability of a safety accident is low, indicating that the safety status of the mine needs attention and may require adjustment of the early warning strategy or increase of the monitoring frequency. In this case, the first preset percentage can be set to 5%.

[0102] Specifically, the strategy generation unit includes:

[0103] An alarm subunit is used to trigger an alarm when the actual percentage is greater than the first preset percentage;

[0104] The sub-unit is divided and adjusted to adjust the preset division standard when the actual proportion is less than the first preset proportion and greater than the second preset proportion;

[0105] A frequency adjustment subunit is used to adjust the preset frequency when the actual proportion is less than the second preset proportion.

[0106] Specifically, the partitioning adjustment subunit includes:

[0107] A marked block is used to mark several mining points that are less than the preset mining safety among the actual mining safety, thereby obtaining marked points;

[0108] Adjust the block and connect it to the marked block to adjust the preset ratio corresponding to the marked point, so as to adjust the preset division standard.

[0109] It is understood that, in this embodiment of the invention, the preset ratio of 1:5 can be adjusted to 1:10 to reduce the standard grid corresponding to the marked point, thereby making the monitoring of high-risk areas more precise.

[0110] Specifically, the frequency adjustment subunit includes:

[0111] A deviation calculation block is used to calculate the deviation between the actual proportion and the second preset proportion;

[0112] A frequency adjustment block, connected to the deviation calculation block, is used to adjust the preset frequency based on the deviation.

[0113] It is understood that in the embodiments of the present invention, the adjusted frequency = (1 + second preset proportion - actual proportion) × preset frequency. According to the above formula, the preset frequency can be increased and adjusted to improve the monitoring frequency of each mining point, increase the amount of monitoring data, and make the monitoring results more accurate and detailed.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.

[0115] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art.
