Description

Technical Field

[0001] The present invention relates to the technical field of risk early warning, and more specifically, to a method, device, medium and computer equipment for early warning of rainfall safety in a tailings pond. Background Art

[0002] Tailings refer to the useless parts left after processing during the ore mining process, that is, the waste in the ore. In the mining industry, the useful parts of the ore are extracted through processes such as beneficiation and smelting, and the remaining waste is the tailings. Tailings are usually in the form of solid, mud or liquid, and may contain some hazardous substances, so they need to be processed and stored in a dedicated tailings pond. A tailings pond is a structure used to store tailings, with the purpose of safely processing and storing these wastes. The safety of tailings ponds is of paramount importance because if a tailings pond suffers an accident such as a leak or a dam collapse, it will cause serious environmental pollution and safety hazards.

[0003] The drainage system of a tailings dam is a key structure for ensuring its safety and stability. Under extreme weather conditions, especially during periods of heavy rainfall, tailings dams face severe safety challenges. The compatibility between rainfall-induced water inflow and the dam's drainage capacity directly impacts water level fluctuations and dam stability. If inflow exceeds the drainage capacity, the water level will rise rapidly, causing a sudden increase in dam pressure and potentially triggering overtopping or dam failure. Therefore, precise monitoring of the safety status of tailings dams under rainfall conditions and graded early warning are urgently needed to ensure their safe operation.

[0004] It's worth noting that in areas prone to heavy rainfall, such as mountainous and coastal areas, tailings ponds present a greater risk due to their complex terrain and concentrated runoff. However, while traditional early warning methods monitor multiple parameters (such as rainfall, water level, and infiltration line), they lack a dynamic coupled analysis model that integrates rainfall, catchment area, and flood discharge capacity, presenting significant limitations. For one thing, when considering only rainfall, the impact of the catchment area surrounding the tailings pond may be overlooked.

[0005] Traditional early warning systems have rigid response mechanisms, lacking dynamic linkage between emergency measures and real-time risk levels. For example, when the risk level escalates, there's no way to automatically adjust floodgate openings or trigger evacuation alarms. Manual decision-making and operations are still required, leading to delayed responses and exacerbating accident risks. Therefore, a dynamic early warning system that integrates multiple factors (rainfall, catchment area, and flood discharge capacity) is urgently needed. Through real-time data collection, dynamic optimization of model parameters, and a tiered emergency response mechanism, this system can achieve precise early warning and closed-loop control of tailings pond safety risks, effectively preventing major accidents such as overtopping and dam failure.

The scope of protection of this application shall be subject to the scope of protection of the claims.

[0025] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0026] Example 1 In order to solve the above problems, Figure 4 As shown, the present invention provides a tailings pond rainfall safety early warning system comprising: The data acquisition module mainly includes four components: a high-precision rain gauge, which can be multiple, with a range of 0-500mm / h and an accuracy of ±0.1mm; each is installed in the vicinity of the tailings pond to measure rainfall in the tailings pond and surrounding areas in real time when it rains. and rainfall intensity Among them, rainfall intensity The definition is the amount of rainfall per unit time. The GIS system is used to dynamically calculate the dynamic catchment area of ​​the area surrounding the tailings pond based on geographic data information. The specific steps are as follows: First, generate geomorphic data according to the area where the tailings pond is located, and use DEM (digital elevation model) to "fill in depressions" to eliminate unnatural low-lying points in the terrain; then generate a water flow direction map for each pixel to determine the path of the water flow; then calculate the water flow accumulation map to identify the area where the water flow is concentrated; on this basis, use the drainage point of the tailings pond as the outlet, and use the flow direction map to reversely deduce all upstream areas that converge into this point, and then delineate the complete catchment area; finally, the GIS system counts the total number of pixels in the area and combines the pixel resolution to accurately calculate the catchment area. ; Ultrasonic flowmeter, range: , the precision is: , installed at the entrance of the tailings pond drainage system. The entrance position of the drainage system can directly reflect the drainage flow out of the reservoir area. Water level sensors are used to monitor water level changes within the tailings pond area. They calculate the rate of water rise and assess future risks based on the rate of water rise, rather than the actual water level. This allows for effective risk prediction and timely risk warnings.

[0027] The data processing module communicates with the high-precision rain gauge, GIS system, ultrasonic flow meter and water level sensor in the data acquisition module, and calculates the comprehensive early warning index according to the predetermined calculation method based on the data collected in the data acquisition module. The comprehensive early warning index integrates multiple key monitoring data into a quantifiable and comparable risk numerical indicator, thereby realizing dynamic assessment of the current safety status of the tailings pond, graded early warning and emergency response decision support.

[0028] The graded warning module automatically determines the current risk level of the tailings pond based on the real-time values ​​of comprehensive warning indicators and triggers the corresponding warning level and emergency response measures. This module ensures that appropriate actions are executed quickly and accurately when risks escalate, thereby achieving dynamic graded warning and closed-loop emergency management and control of the tailings pond under rainfall conditions.

[0029] The emergency execution unit is used to link with the corresponding specific equipment according to the emergency response measures distributed by the graded warning module. The emergency execution unit mainly includes a chute control system, an audible and visual alarm device, and an emergency communication platform. The function of the chute control system is to automatically adjust the opening and closing status of the cover of the tailings pond drainage chute according to the warning level, thereby dynamically controlling the effective cross-section of the flood discharge channel, improving the drainage capacity, and slowing down the rate of water level rise in the reservoir. The function of the audible and visual alarm device is to immediately emit a strong sound and flash signal when the warning level reaches a high risk, providing efficient and intuitive risk warnings to the area surrounding the tailings pond; the function of the emergency communication platform is to serve as a central system for information transmission and command dispatch, receiving monitoring data and warning signals in real time, and quickly conveying the corresponding emergency response instructions to managers at all levels and on-site emergency units.

[0030] Based on the above system, such as Figure 1 As shown, this embodiment further provides a comprehensive early warning method, which includes: S1. Calculate the amount of water entering the reservoir ; The amount of water entering the reservoir Specifically, the rainfall , the rainfall intensity and the comprehensive calculation and generation of geographic information of the area where the tailings pond is located; The geographic information is obtained through the GIS system. , the rainfall intensity Specifically, it is obtained through a high-precision rain gauge; the amount of water entering the reservoir It is one of the primary factors that determine whether there is a safety risk in the tailings pond during rainfall. The greater the amount of water entering the reservoir, the faster the water level in the reservoir rises; a large amount of water entering the reservoir may cause the liquid level in the reservoir to rise, resulting in enhanced seepage in the tailings dam body and increased pore water pressure, which can easily cause engineering diseases such as dam softening, landslides, and rising infiltration lines, increasing the risk of dam failure.

[0031] S2, based on the drainage flow And the amount of water entering the reservoir Calculate the difference in flood discharge capacity ; The difference in discharge capacity reflects the dynamic balance between the amount of water flowing into the tailings pond per unit time and the discharge capacity. When the water inflow exceeds the instantaneous discharge capacity of the flood discharge system, the water level of the tailings reservoir will continue to rise. When the flood discharge capacity is sufficient, the reservoir water will not accumulate; when It is obviously positive and continues to expand, indicating that the tailings pond has entered a state of deficit; combined with As well as rainfall trend forecasts, it helps to deploy storage and increased discharge strategies in advance to improve overall flood discharge efficiency.

[0032] S3, based on the flood discharge capacity difference and the water level rising rate, and calculate the comprehensive early warning index; the water level rising rate is specifically the ratio of the difference in water level height change to the rising time; By using two key risk factors for quantitative integration, a unified risk scoring index is generated to determine whether the tailings pond has entered an unsafe state and which level of warning area it has entered, forming a more comprehensive risk assessment dimension, avoiding only looking at the flow rate without looking at the water level, or only looking at the water level and ignoring the deviation of the water inflow speed. The water level is not large, but it rises rapidly, indicating that the system is slow to respond or the drainage efficiency is lagging. It is difficult to trigger an early warning by relying solely on the flow difference. The comprehensive indicator can capture the risk in time, issue a signal in advance, and improve the sensitivity of the system warning. Further combined with geographic information, the comprehensive indicator algorithm can adapt to different terrains, rainfall types and drainage system structures; S4. Based on the comprehensive early warning indicators, execute preset emergency response measures.

[0033] In summary, this embodiment provides a hierarchical early warning response method, which dynamically calculates the amount of water entering the reservoir by integrating rainfall, rainfall intensity and geographic information, estimates the difference in flood discharge capacity in real time in combination with drainage flow, and further introduces the water level rise rate to construct a comprehensive early warning index, thereby achieving an accurate assessment of the risk of the tailings pond during rainfall. This indicator combines the inflow-outflow balance relationship with the water level change trend, avoids misjudgment caused by a single parameter early warning, and improves the sensitivity and accuracy of the early warning. At the same time, the system can automatically trigger corresponding emergency response measures according to the level of the comprehensive indicator, such as opening the chute cover, evacuating personnel or starting flood discharge facilities, forming a full-process closed-loop control mechanism of monitoring-assessment-response, and effectively improving the safety and control level of the tailings pond in extreme weather.

[0034] In one embodiment, the geographic information specifically includes: surface runoff coefficient and the diversion coefficient ; The surface runoff coefficient The diversion coefficient is calibrated by the historical rainfall data and historical runoff data of the area where the tailings pond is located. Specifically, it is determined by calibrating the flood interception capacity of the area where the tailings pond is located.

[0035] In practical applications, the surface runoff coefficient It is a coefficient used to measure the proportion of surface rainfall that is converted into surface runoff (i.e. not absorbed by the soil or evaporated). The value range is usually between 0 and 1. It is calculated by the runoff coefficient method, specifically: ; in, represents the total runoff volume, represents the total amount of rainfall; Represents the catchment area.

[0036] In practical applications, the split coefficient This represents the proportion of rainwater that is intercepted or diverted by artificial drainage facilities (such as drainage ditches, intercepting ditches, and diversion channels) during rainfall. It reflects the amount of water that is "diverted" by the drainage system before entering the tailings pond and is an important correction factor in the calculation of water inflow to the tailings pond.

[0037] ; in, Indicates the amount of water removed by the drainage setting. Indicates the total amount of water that should have flowed into the tailings pond. When , it means there is no diversion and all water flows into the tailings pond; when When , it means that almost all the incoming water has been discharged and there is almost no water entering the reservoir.

[0038] In one embodiment, the calculation of the water inflow , specifically including: ; in, Indicates the rainfall in the area where the tailings pond is located; Indicates the catchment area of ​​the area where the tailings pond is located; Indicates the rainfall intensity in the area where the tailings pond is located.

[0039] In actual use, when calculating the amount of water entering the reservoir, the factor of the diversion coefficient is specifically , indicating the diversion coefficient It is used to deduct the part that is pre-diverted by the drainage system to obtain the actual amount of water entering the tailings pond.

[0040] The effect of rainfall intensity on surface runoff is nonlinear. The greater the rainfall intensity, the easier it is to generate surface runoff per unit area, but the growth trend slows down. Rather than directly To fit a more reasonable hydrological response.

[0041] This formula integrates the key factors that affect the amount of water entering the tailings pond and reflects the comprehensive effect of rainfall and water collection process. represents the total rainfall, The catchment area directly determines the basic scale of the collected water volume; The nonlinear effect of rainfall intensity is introduced to accord with the fact that "sudden rain is more likely to generate runoff" in practice, but the square root is used to avoid over-amplification of short-term heavy rainfall. is the surface runoff coefficient, which reflects the regulation of surface conditions such as topography, soil, and vegetation on runoff efficiency; The formula takes into account the interception of rainwater by drainage ditches and other facilities, making reasonable reductions and corrections to the actual inflow. Overall, this formula integrates hydrophysical and engineering flood discharge conditions and can effectively predict the inflow of water into the tailings pond.

[0042] In one embodiment, the flood discharge capacity difference and the water level rise rate to calculate the comprehensive early warning index , specifically including: ; in, represents the comprehensive early warning indicator; Indicates the water level; Indicates the rate of water level rise; Represents the water level sensitivity weighting factor.

[0043] In practical applications, early warning indicators Reasonably quantify and integrate the two core dynamic factors of tailings dam safety risk. First, It reflects the relative difference between the amount of water entering the reservoir and the flood discharge capacity, and directly reveals the water balance state. If the amount of water entering the reservoir continues to exceed the flood discharge capacity, the water level in the reservoir will inevitably rise, and the risk will increase. Secondly, the water level rise rate It captures the dynamic trend of water level changes, reflects the speed of water level rise, and supplements the reservoir response hysteresis or drainage system efficiency issues that may be ignored by simple flow difference; parameters As a weighting factor, it adjusts the impact of water level changes on the comprehensive indicator, achieving dynamic optimization of sensitivity. By combining the complementary perspectives of flow and water level, this indicator improves the accuracy and timeliness of early warnings. It can more comprehensively and promptly reflect the safety risk level of tailings ponds, facilitate scientific decision-making and graded response, and reflect the multidimensional and dynamic nature of risk assessment.

[0044] In one embodiment, the surface runoff coefficient And the water level sensitivity weight factor All are dynamically calibrated through federated learning algorithms.

[0045] In practical applications, federated learning is a distributed machine learning method. Its core idea is to train model parameters independently in multiple data sources, and then upload the model updates from each location to the central server for aggregation and fusion to generate a global optimization model. The updated model is then distributed to each participating node. In this embodiment, federated learning is used to calculate the surface runoff coefficient based on the area where the tailings pond is located. and water level sensitivity weighting factor Perform local calculations and upload the results to the server. After dynamic calibration, the model is combined with multiple data sources in other tailings ponds, so that the model can more accurately adapt to the terrain, hydrological conditions and operating conditions of different tailings ponds, thereby improving the accuracy and generalization ability of the early warning system.

[0046] In one embodiment, executing preset emergency response measures based on the comprehensive early warning indicators specifically includes: when When the risk is very low, the system will continue to monitor without taking any other measures; the system will be kept in a low-load state to avoid false triggering and waste of resources; no intervention will be made when the risk is extremely low, which will help the system save energy, operate efficiently, and reduce the possibility of human interference and misoperation; when Increase the frequency of inspections and check the status of flood drainage facilities when necessary; in the low-risk stage, conduct low-cost manual inspections and facility status checks to enhance awareness of equipment operating status, which helps to detect drainage blockages, equipment aging and other problems in advance, implement preventive maintenance, and avoid risk accumulation; when When the water level rises, some chute covers are opened to expand the flow section. By partially opening the chute covers, the flow section is increased and the drainage capacity is enhanced. At the same time, it does not rely entirely on the emergency system, taking into account both safety and system load control. It has a certain adjustment capacity, which can delay the rising trend of the water level and buy time for further response. when When the tailings dam is in an unstable state, the chute cover is fully opened and personnel in the downstream low-risk area are evacuated. Fully opening the chute cover can maximize the discharge flux. At the same time, personnel evacuation measures are initiated in advance, which can effectively avoid the risk of casualties caused by potential instability of the tailings dam. This is the simultaneous implementation of engineering response and safety response, ensuring the safety of manpower and equipment. when When a flood occurs, emergency flood discharge facilities are activated, triggering sound and light alarms and full evacuation orders. This level represents the highest risk response. By activating emergency facilities such as spillways or flood discharge pumps, water is discharged quickly and compulsorily to lower the reservoir water level. Sound and light alarms and full evacuation ensure the safety of people downstream, achieving automation, rapid response, and multi-channel linkage under the most extreme working conditions, minimizing disaster losses. In practical applications, the graded response design takes into account response efficiency, resource utilization and safety assurance, embodies the technical progression from light intervention to comprehensive disposal, control accuracy and emergency reliability, adapts to various rainfall intensities and terrain and hydrological conditions, and improves the intelligence level of tailings pond risk management.

[0047] In one embodiment, the method further comprises: After executing the emergency response measures, it is determined whether the comprehensive warning indicator drops below the warning threshold after a predetermined time. If so, monitoring is continued; if not, the emergency response measures are upgraded.

[0048] In practice, the system sets a predetermined time window during which it continuously monitors changes in the comprehensive early warning indicator S. At the end of this time window, the system determines whether the current S value has fallen below a safety threshold (for example, S ≤ 0.2 or lower). This indicates that rainfall may have weakened, the rising water level trend has been effectively curbed, flood drainage capacity has been restored, and on-site risks have been reduced.

[0049] If this condition is met (the S value drops below the threshold), the system will determine that the risk has been mitigated and there is no need to upgrade the response measures. It will only retain the monitoring status and maintain alert.

[0050] If these conditions are not met—that is, if the comprehensive early warning indicator remains in the high-risk range or continues to rise—the previous response was insufficient to control the risk. For example, if rainfall continues or intensifies, water levels continue to rise rapidly, or the drainage system is clogged or inefficient, the system will automatically upgrade the emergency response level, for example, from simply opening the chute to forced flood discharge with audible and visual alarms, further strengthening prevention and control measures to prevent the risk of the tailings pond from worsening.

[0051] Based on the above scheme, a closed-loop response mechanism can be formed, which is not a one-time warning, but a continuous assessment + dynamic adjustment; it avoids the problems of over-response or under-response and improves the efficiency of resource utilization; the system has the ability of "self-correction" and can make appropriate decisions in time under various uncertainties; it is conducive to the safe dispatch of on-site personnel and reduces the safety risks caused by misjudgment or missed judgment.
