Description

Technical Field

[0001] The invention relates to the field of tailings pond safety technology, and in particular to a method, a device, an electronic device and a storage medium for setting rainfall monitoring points in a tailings pond. Background Art

[0002] Tailings ponds are places for storing ore sorting waste and are a man-made high-potential debris flow hazard source. For valley-type tailings ponds, floods caused by rainfall pose a serious safety threat to tailings ponds, leading to disasters such as flooding and dam breaches, which have a serious impact on the safety of people's lives, property and the environment downstream of the tailings ponds. Accurate monitoring of rainfall can effectively predict floods and help tailings ponds take emergency precautions in advance, thereby avoiding flooding and dam breaches.

[0003] At present, the common method for rainfall monitoring is to treat the entire tailings pond and the upstream catchment area as a whole and set up only one rainfall monitoring point. However, the catchment areas of different tailings ponds are not the same size, and the rainfall at different locations within the catchment area may be inconsistent. Therefore, relevant technicians have proposed dividing the tailings pond into different sub-catchment areas and setting up rainfall sensors in each sub-catchment area to achieve rainfall distribution monitoring. However, for some tailings ponds, the number of sub-catchment areas may reach more than 10. If rainfall sensors are deployed in all of them, the monitoring cost will be too high.

[0060] A common method for monitoring rainfall in tailings ponds is to treat the entire tailings pond and the upstream catchment area as a whole and only set up one rainfall monitoring point. However, the catchment areas of different tailings ponds are not the same size, and the rainfall at different locations within the catchment area may be inconsistent.

However, for some tailings ponds, the number of sub-catchment areas may reach more than 10. If rainfall sensors are deployed in all of them, the monitoring cost will be too high.

[0061] Example 1

[0062] The embodiment of the present invention provides a method for setting rainfall monitoring points in a tailings pond, which effectively solves the problem of excessively high monitoring costs caused by arranging rainfall sensors in all sub-catchment areas of the tailings pond.

[0070] The sub-catchment outside the reservoir refers to the area outside the tailings pond but with direct or indirect water flow connection with the tailings pond. The water flow in these areas may enter the tailings pond through surface runoff and groundwater infiltration. The sub-catchment outside the reservoir is divided according to the ditch inside the sub-catchment outside the reservoir. The closed circle formed by the ridge line above the ditch inside the sub-catchment outside the reservoir and the edge line of the internal catchment is regarded as the sub-catchment outside the reservoir, such as Figure 3 As shown, the embodiment of the present invention can obtain 5 sub-catchment areas outside the reservoir, which are H 1- H 5, whose areas are F 1- F 5. In the three-dimensional measured topographic map, the area of ​​the watershed within the reservoir and the sub-watershed outside the reservoir are delineated. The drainage area results of the watershed area are shown in Table 1.

[0075] S210. Obtain the watershed parameters of the tailings pond location and the topographic parameters of each sub-catchment area outside the pond.

[0076] In an embodiment of the present invention, the watershed parameters of the tailings pond location are obtained according to the local hydrological manual, and the watershed parameters include but are not limited to runoff generation zones, rainfall runoff coefficients, infiltration coefficients and other parameters.

In an embodiment of the present invention, a unit line algorithm is used for hydrological calculation, and a flood process curve of the sub-catchment area outside the reservoir is drawn. The specific steps are as follows:

[0079] First, the rainfall amount every 10 minutes obtained by monitoring the rain gauge is a, and a is used as the continuous rainfall amount calculated this time. In the embodiment of the present invention, a is assumed to be 2 mm, and the rainfall period is Δt=1 / 6h.

[0080] Then, the hydrological manual was consulted to find that the runoff zone of the watershed where the tailings pond is located is Zone VII. According to the rainfall runoff table of Zone VII, under the continuous rainfall of 2 mm every 10 minutes, the rainfall intensity in each period is I (mm / h), as shown in Table 2.

[0096] In the above formula, S(t) represents the flow function in time period t, u(t) represents the flow increment function from time period t-1 to time period t, q(t) Represents the unit line function for each rainfall period.

[0097] The net rainfall intensity of each rainfall period I N The corresponding unit line function q ( t ) is multiplied by the net rain condition to obtain the flood process formed under the net rain condition. The flood process formed under the net rain condition in different rainfall periods is added together to obtain the flood process curve formed by the entire rainfall process.

[0103] The flood flow into the reservoir is calculated based on the area of ​​the reservoir catchment area and the rainfall intensity. The calculation formula for the flood flow into the reservoir is as follows:

[0104]

[0105] In the above formula, Q represents the flood flow into the reservoir catchment area, in m 3 / s; F represents the area of ​​the catchment area in the reservoir, in m 2 ; I represents rainfall intensity, unit is mm / s.

[0106] In the embodiment of the present invention, the area of ​​the water catchment area in the reservoir F =108753m 2 , the rainfall every 10 minutes monitored by the rain gauge is 2 mm, then the flood flow into the reservoir catchment area is:

[0114] In the embodiment of the present invention, the calculation is performed by taking the sub-catchment area H1 outside the reservoir as an example, and its flood peak time is 700 minutes. Then the total amount of flood directly entering the reservoir during the flood peak time of the sub-catchment area H1 outside the reservoir is:

[0121]

[0122] In the above formula, H i Indicates i The real-time water level of the tailings pond after the total amount of flood water entering the tailings pond directly from the flood peak time of each sub-catchment area outside the reservoir enters the tailings pond, in meters; H ( V i ) represents the corresponding relationship between the real-time water level of the tailings pond and the total amount of flood directly entering the pond during the flood peak period.

[0123] Combined with the contour map of the tailings pond, the corresponding relationship between the water level rise of the tailings pond and the total amount of flood water directly entering the reservoir during the flood peak period is obtained. Specifically, the area of ​​adjacent contour lines on the contour map is first obtained, and the mean of the area of ​​adjacent contour lines is calculated. The product of the mean of the area of ​​adjacent contour lines and the height difference between adjacent contour lines is the volume between adjacent contour lines. The volume between contour lines is added to obtain the flood control storage capacity corresponding to different contour elevations. Then, the calculated total amount of flood water directly entering the reservoir during the flood peak period is substituted into the flood control storage capacity corresponding to the contour elevation, and the real-time water level of the tailings pond corresponding to the total amount of flood water directly entering the reservoir is obtained by interpolation.

[0124] In the embodiment of the present invention, the initial water level of the tailings pond is 1008.8m, and its contour elevation and the corresponding flood control storage capacity are shown in Table 7.

[0133] In the above formula, q i For the i The tailings pond discharge volume during the flood peak time of the sub-catchment area outside the reservoir, unit: m 3 / s; q ( H i ) is the corresponding relationship between the real-time water level of the tailings pond and the discharge volume of the tailings pond during the flood peak time.

[0134] Optionally, the correspondence between the water level elevation of the tailings pond and the discharge of the tailings pond during the flood peak time can be obtained through the empirical formula corresponding to the form of the tailings pond flood discharge structure, or through a physical model discharge test. The forms of tailings pond flood discharge structures include but are not limited to well-pipe type, well-hole type, trough-pipe type, trough-hole type, spillway type, or a combination of the above forms. The physical model discharge test directly obtains the relationship between the water level elevation height of the tailings pond and the discharge of the tailings pond based on laboratory hydraulic tests.

[0135] According to the water level elevation height and initial water level of the tailings pond, the real-time water level of the tailings pond can be calculated. The calculation formula is:

[0136]

[0137] In the above formula, H i Indicates i The real-time water level of the tailings pond after the total amount of flood water entering the tailings pond directly from the flood peak time of each sub-catchment area outside the reservoir enters the tailings pond, in meters; H 0 represents the initial water level of the tailings pond, in m; L i Indicates i The height of the tailings pond water level rise after the total amount of flood water directly entering the tailings pond during the flood peak time of each sub-catchment area outside the reservoir enters the tailings pond, in meters.

[0138] In an embodiment of the present invention, a physical model discharge test is used to obtain the relationship between the water level rise height of the tailings pond and the discharge volume of the tailings pond as shown in Table 9 below.

[0141] In the embodiment of the present invention, the initial water level of the tailings pond is 1008.8 m, and the relationship between the water level elevation of the tailings pond and the discharge flow of the tailings pond is shown in Table 10 below.

[0142] Table 10. Schematic diagram of the relationship between tailings pond water level elevation and tailings pond discharge

[0144] Substituting the real-time water level height of the tailings pond during the flood peak time of the five sub-catchments outside the reservoir in Table 8 into Table 10 for interpolation calculation, the tailings pond discharge during the flood peak time of the five sub-catchments outside the reservoir can be obtained as shown in Table 11.

[0145] Table 11. Schematic diagram of tailings pond discharge during flood peak time in 5 sub-catchments outside the reservoir

[0146]

[0147] S500, obtaining the importance of each sub-catchment area outside the reservoir according to the peak flow, the flood flow entering the reservoir and the discharge of the tailings reservoir during the peak time.

[0148] The flood inflow of the reservoir catchment area, the peak flow of each sub-catchment area outside the reservoir and the discharge of the tailings pond during the peak time are compared, and the importance of each sub-catchment area outside the reservoir is determined based on the comparison results. Figure 7 5 is a fifth schematic diagram of the method for setting rainfall monitoring points in a tailings pond provided by an embodiment of the present invention. Figure 7 As shown in Figure 2, determining the importance of each sub-catchment area outside the reservoir includes the following steps:

[0149] S510. If there is a sub-catchment outside the reservoir whose flood peak flow is less than the first threshold, the sub-catchment outside the reservoir is determined as the third-level importance, and the first threshold is the minimum value of the flood flow into the reservoir and the tailings pond discharge during the flood peak time of the sub-catchment outside the reservoir.

[0150] If there is i When M i <min( Q , q i ) i The sub-catchments outside the reservoir are determined as three levels of importance, among which M i Indicates i Peak flow of sub-catchment areas outside the reservoir, min( Q , q i ) is the first threshold, which represents the minimum value of the inflow flood flow and the tailings pond discharge during the flood peak time of the sub-catchment area outside the reservoir.

[0151] S520. If there is a sub-catchment outside the reservoir whose peak flow is greater than or equal to the first threshold and less than the second threshold, the sub-catchment outside the reservoir is determined as the secondary importance, and the second threshold is the maximum value of the inflow flood flow and the tailings pond discharge during the peak time of the sub-catchment outside the reservoir.

[0152] If there is i When min(Q,q i )≤M i <max(Q,q i ) When i The sub-catchment areas outside the reservoir are determined as secondary importance, max( Q , q i) is the second threshold, which represents the maximum value of the tailings pond discharge during the flood peak time of the inflow flood flow and the sub-catchment area outside the reservoir.

[0153] S530: If there is a sub-catchment area outside the reservoir whose flood peak flow is greater than or equal to the second threshold, the sub-catchment area outside the reservoir is determined as the first-level importance.

[0154] If there is i When M i ≥ max(Q,q i ) When i The sub-catchment area outside the reservoir is determined as the first-level importance.

[0155] In an embodiment of the present invention, a schematic table of the importance of five sub-catchments outside the reservoir is obtained by comparing the inflow flood flow of the reservoir catchment area, the peak flow of each sub-catchment area outside the reservoir, and the tailings pond discharge during the peak time, as shown in Table 12 below.

[0156] Table 12. Schematic diagram of the importance of the five sub-catchments outside the reservoir

[0157]

[0158] S600: Set corresponding rainfall monitoring points in the sub-catchment areas outside the reservoir according to their importance.

[0159] Figure 8 6 is a schematic diagram of the method for setting the rainfall monitoring points in the tailings pond according to an embodiment of the present invention. Figure 8 As shown in Figure 1, the setting of rainfall monitoring points includes the following steps:

[0160] S610: If there is a sub-catchment area outside the reservoir with a first-level importance, it is determined to set a rainfall monitoring point in the sub-catchment area outside the reservoir.

[0161] If there is i When the importance of a sub-catchment outside the reservoir is the first-level importance, it means that the flood formed in the sub-catchment outside the reservoir has a great impact on the tailings pond. In this case, a rainfall monitoring point must be set up in the sub-catchment outside the reservoir to evaluate the flood formed. The rainfall monitoring point may be equipped with equipment including but not limited to rain gauges, rain sensors and rainfall intensity meters.

[0162] S620. If there is a sub-catchment area outside the reservoir with a secondary importance, a rainfall monitoring point of the sub-catchment area outside the reservoir is set according to the actual demand for monitoring accuracy.

[0163] If there is iWhen the importance of a sub-catchment outside the reservoir is the second-level importance, it means that the flood formed in the sub-catchment outside the reservoir has a certain impact on the tailings pond. Whether to set up rainfall monitoring points can be selected according to the actual needs of monitoring accuracy. If the monitoring accuracy requirements for the tailings pond are high, rainfall monitoring points can be set up. If the monitoring accuracy is low, rainfall monitoring points may not be set up.

[0164] S630: If there is a sub-catchment area outside the reservoir with a third-level importance, it is determined that no rainfall monitoring point is set in the sub-catchment area outside the reservoir.

[0165] If there is i When the importance of a sub-catchment outside the reservoir is level three, it means that the flood formed in the sub-catchment outside the reservoir has little impact on the tailings pond, and there is no need to set up rainfall monitoring points.

[0166] In the embodiment of the present invention, the evaluation results of whether to set rainfall monitoring points in the five sub-catchments outside the reservoir are shown in Table 13 below.

[0167] Table 13. Schematic diagram of the evaluation results of whether to set up rainfall monitoring points

[0168]

[0169] Among them, the area where rainfall monitoring points must be set up is the third sub-catchment area H3 outside the reservoir. The areas where rainfall monitoring points can be set up according to the actual needs of monitoring accuracy are the second sub-catchment area H2 outside the reservoir and the fourth sub-catchment area H4 outside the reservoir. The areas where rainfall monitoring points may not be set up are the first sub-catchment area H1 outside the reservoir and the fifth sub-catchment area H5 outside the reservoir.

[0170] As a further implementation method of the present invention, the location of the rainfall monitoring point can be dynamically adjusted according to the changes in the water catchment area inside the reservoir and the sub-water catchment areas outside the reservoir. As the tailings discharge from the tailings pond continues to increase, the area of ​​the water catchment area inside the reservoir will continue to increase, and the area of ​​each sub-water catchment area outside the reservoir will continue to decrease. According to the aforementioned steps S100-S500, the importance of each sub-water catchment area outside the reservoir is determined in real time, and the setting location of the rainfall monitoring point of each sub-water catchment area outside the reservoir is dynamically adjusted.

[0171] In the embodiment of the present invention, if the area of ​​the catchment area of ​​the tailings pond in the next stage increases to F=126753m 2 The corresponding inflow flood flow, the area of ​​the five sub-catchments outside the reservoir, the peak time, the peak flow and the tailings pond discharge during the peak time have all changed. The results of the rainfall monitoring point settings recalculated and determined according to steps S100-S500 are shown in Table 14 below.

[0172] Table 14. Schematic diagram of the results of setting up rainfall monitoring points to be determined in the next stage

[0173]

[0174] Among them, since the importance of the third sub-catchment area H3 outside the reservoir becomes the second-level importance, it can be selected whether to set the rainfall monitoring point area as the second sub-catchment area H3 outside the reservoir according to the actual demand for monitoring accuracy. 2、 The third and fourth sub-catchment areas outside the reservoir H3 and H4, and the areas where rainfall monitoring points may not be set are the first and fifth sub-catchment areas outside the reservoir H1 and H5.

[0175] The method for setting rainfall monitoring points in the tailings pond provided by the embodiment of the present invention can divide the importance of the sub-catchment areas according to the actual impact of floods on the tailings pond caused by different sub-catchment areas, and arrange rainfall monitoring points in a targeted manner according to the order of importance, thereby realizing accurate monitoring of rainfall in different regions while minimizing the number of rainfall monitoring points and effectively reducing the monitoring cost. At the same time, according to the changes in the external drainage area inside and outside the reservoir during the operation of the tailings pond at different times, the rainfall monitoring points are adjusted in real time, realizing the dynamic optimization arrangement of the distributed rainfall monitoring points in the tailings pond.
