[0025] Specifically, the preset frequency in the embodiment of the present invention is 30 minutes per time.

[0028] See also Figure 2 As shown, the division module 10 includes: A standard determination unit 11 is used to identify the edge contour of the area to be mined, reduce the edge contour by a preset ratio, and obtain a standard division grid; 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, and obtain a plurality of divided areas as the points to be mined.

[0029] Specifically, the preset ratio in the embodiment of the present invention is 1:5.

[0030] Specifically, the standard determination unit of the embodiment of the present invention can accurately identify the edge contour of the area to be mined to provide a basis for subsequent division, thereby ensuring the accuracy and pertinence of the division. By reducing the edge contour by a preset ratio, the division result is more unified and adapted to the actual area to be mined, which is convenient for subsequent data collection and risk assessment, and improves the applicability of the division. The division unit can accurately divide the area to be mined according to the standard division grid, which is helpful for the meticulousness of subsequent data collection and risk assessment, and improves the accuracy of the early warning system. Through the gridded division method, the points to be mined are clearer and more definite, which is convenient for subsequent data collection, risk assessment and strategy generation, thereby improving the accuracy of the early warning system.

[0031] See also Figure 3As shown, the data processing module 30 includes: A geological safety calculation unit 31 is used to compare the real-time soil softness with the preset soil softness, compare the real-time groundwater pressure with the preset groundwater pressure range, and calculate the geological safety based on the comparison results; An environmental safety calculation unit 32, used to compare the real-time gas concentrations with the preset gas concentrations, the real-time dust concentrations with the preset dust concentrations, and calculate the environmental safety based on the comparison results; A weight determination unit 33, used to determine the preset weight based on the comparison result of the geological safety and the environmental safety; The safety obtaining unit 34 is connected to the geological safety judging unit 31, the environmental safety judging unit 32 and the weight determining unit 33, and is used to obtain actual mining safety based on the geological safety, the environmental safety and the preset weight.

[0032] Specifically, the embodiment of the present invention sets the geological safety calculation unit to comprehensively consider multiple geological factors such as real-time soil softness and real-time groundwater pressure, and conducts a multi-dimensional geological safety assessment, which helps to more accurately identify potential geological risks. By comparing real-time data with preset values, the geological safety index is 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 real-time monitoring and comparing the differences between gas concentration and dust concentration and preset values, the changes in environmental risks are captured, and the environmental safety index is accurately calculated. The weight determination unit dynamically adjusts the preset weight according to the comparison results of geological safety and environmental safety, making the risk assessment more flexible and accurate, and able to adapt to changes in different mining conditions and risk conditions, thereby improving the accuracy and comprehensiveness of the 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.

[0033] Specifically, the geological safety calculation unit includes: A first calculation subunit is used to calculate the proportion of a number of real-time soil softness values ​​less than the preset soil softness values, and determine the collapse safety according to the proportion result; A 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 determine the water pressure safety according to the proportion result; The geological safety calculation subunit is connected to the first calculation subunit and the second calculation subunit, and is used to calculate the geological safety according to the collapse safety and the water pressure safety.

[0034] It is understandable that a safe soil softness may be set below a certain value. Exceeding this value may indicate that the soil is too soft and there is a risk of collapse. The specific value of the preset soil softness needs to be determined based on the actual situation of each coal mine and may be adjusted as mining progresses and geological conditions change. An indicator of soil softness can be represented by a firmness coefficient. The value range of the firmness coefficient is between 0 and 1. The calculation formula of the firmness coefficient is prior art and will not be repeated here. In the embodiment of the present invention, the preset soil softness can be set to 0.5.

[0035] It can be understood that the preset groundwater pressure range described in the embodiment of the present invention is determined by the historically detected groundwater pressure, and the minimum and maximum values ​​of several historically detected groundwater pressures are used as the preset groundwater pressure range. Being outside the preset groundwater pressure range may cause problems such as mine water gushing or support structure failure.

[0036] It can be understood that the geological safety described in the embodiment of the present invention is the product of the collapse safety and the water pressure safety.

[0037] Specifically, the environmental safety judgment unit includes: A gas safety calculation subunit, used to calculate the proportion of the real-time gas concentrations that are greater than or equal to the preset gas concentration, and determine the gas safety according to the proportion result; A dust safety calculation subunit, used to calculate the proportion of the real-time dust concentrations that are greater than or equal to the preset dust concentration, and determine the dust safety according to the proportion result; The environmental safety calculation subunit is connected to the gas safety calculation subunit and the dust safety calculation subunit, and is used to calculate the environmental safety according to the gas safety and the dust safety.

[0038] It can be understood that, in the embodiment of the present invention, under normal circumstances, the gas concentration in the coal mine should be controlled below 1%. When the gas concentration reaches 5% to 15%, it may cause an explosion when encountering a fire source. The preset gas concentration in the embodiment of the present invention is 1%.

[0039] It can be understood that according to the MT / T1171-2019 standard, the total dust concentration and respirable dust concentration in coal mines in the embodiment of the present invention have specific restrictions. For example, the limit value of the total dust concentration may be 10 mg / m³ (10 milligrams per cubic meter), and the limit value of the respirable dust concentration may be 5 mg / m³. The preset dust concentration in the embodiment of the present invention is 5 mg / m³.

[0040] It can be understood that the environmental safety described in the embodiment of the present invention is the product of the gas safety and the dust safety.

[0041] Specifically, the weight determination unit includes: A safety comparison subunit, used to compare the geological safety and the environmental safety to obtain a safety comparison result; The weight calculation subunit is connected to the security comparison subunit and is used to determine the weight distribution ratio according to the security comparison result, so as to further determine the preset weight.

[0042] It can be understood that the embodiment of the present invention determines the weight distribution ratio according to the safety comparison result and may include that 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%.

[0043] See also Figure 4 As shown, the strategy generation module 40 includes: A safety comparison unit 41 is used to compare the actual mining safety with the preset mining safety to obtain a safety comparison result; A proportion calculation unit 42, connected to the safety comparison unit 41, for calculating an actual proportion of the actual mining safety being less than the preset mining safety; A strategy generating unit 43, connected to the proportion calculating unit 42, for determining whether to issue an alarm, or adjusting the preset division standard, or adjusting the preset frequency according to a comparison result between the actual proportion and the first preset proportion and the second preset proportion; Among them, the first preset proportion is greater than the second preset proportion.

[0044] It can be understood that the preset mining safety described in the embodiment of the present invention can be set according to the historical data of coal mining, the mining safety corresponding to the historical mining safety of the coal mine is determined, and the average of several historical mining safety safety is judged as the preset mining safety. In the embodiment of the present invention, the preset mining safety can be set as a percentage value. For example, several historical mining safety safety are 92%, 95%, and 97% respectively. 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.

[0045] It can be understood that the setting of the first preset proportion and the second preset proportion in the embodiment of the present invention can determine two proportion thresholds based on the analysis of past safety accidents and early warning responses of the mine. For example, if historical data shows that when the safety of more than 20% of the mining sites is below the standard, the probability of a safety accident increases significantly, then the first preset proportion can be set to 20%. When the safety of less than 5% of the mining sites is below the standard, the probability of a safety accident is low, indicating that the safety status of the mine needs attention and may need to adjust the early warning strategy or increase the monitoring frequency, then the first preset proportion can be set to 5%.

[0046] Specifically, the strategy generation unit includes: an alarm subunit, configured to generate an alarm when the actual proportion is greater than the first preset proportion; a division adjustment subunit, configured to adjust the preset division standard when the actual proportion is less than the first preset proportion and greater than the second preset proportion; The frequency adjustment subunit is used to adjust the preset frequency when the actual proportion is less than the second preset proportion.

[0047] Specifically, the division adjustment subunit includes: Marking blocks, for marking a number of points to be mined whose actual mining safety is less than the preset mining safety, to obtain marked points; The adjustment block is connected to the marking block and is used to adjust the preset ratio corresponding to the marking point position so as to adjust the preset division standard.

[0048] It is understandable that the embodiment of the present invention can adjust the preset division standard to adjust the preset ratio of 1:5 to 1:10, so as to reduce the standard division grid corresponding to the marked point, thereby making the monitoring of high-risk areas more refined.

[0049] Specifically, the frequency adjustment subunit includes: A deviation calculation block, used for calculating the deviation between the actual proportion and the second preset proportion; The frequency adjustment block is connected to the deviation calculation block and is used for adjusting the preset frequency based on the deviation.

[0050] It can be understood that in the embodiment 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 increase the monitoring frequency of each point to be mined, increase the amount of monitoring data, and make the monitoring results more accurate and detailed.

[0051] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle 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 fall within the protection scope of the present invention.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
