[0025] Example 1

[0026] The disclosed embodiment provides a method for estimating the flood control storage capacity of a dry-type tailings pond, which is used to solve the problem of inaccurate estimation of the flood control storage capacity.

[0027] See also Figure 1 This embodiment proposes a method for estimating the flood control storage capacity of a dry tailings pond, which includes steps S101 to S104. Each step is described in detail below.

[0028] Step S101, determining at least one candidate tail area and an estimated stacking order of each candidate tail area in each tail area of ​​the tailings pond according to the tailings pond information, and calculating the estimated stacking tailings volume corresponding to each candidate tail area according to the spatial parameters of each candidate tail area.

[0029] In this embodiment, as the tailings in the tailings pond are continuously discharged and accumulated, the storage capacity of the tailings pond will gradually decrease. If the height of the sub-dam remains unchanged, the higher the height of the pile in the reservoir, the less the remaining flood control storage capacity, and the weaker the ability to cope with extreme weather such as heavy rain. Therefore, when estimating the flood control storage capacity, it is necessary to fully consider the impact of the height of the pile in the reservoir on safety and stability.

[0030] First, the tailing position of the tailings pond needs to be determined. Specifically, at least one candidate tailing area that needs to be built in each tailing area of ​​the tailings pond is determined according to the tailings pond information, and the estimated building order of each candidate tailing area.

[0031] Exemplarily, if there are tail regions A, B, C, and D, and tail regions A and D are determined as candidate tail regions from each tail region in turn, the estimated stacking order of candidate tail region A is the first, and the estimated stacking order of candidate tail region D is the second.

[0032] At the same time, after determining a candidate tail area, it is necessary to calculate the estimated tailings volume required for the candidate tail area according to the spatial parameters of the candidate tail area. After the estimated tailings volume of the candidate tail area is calculated, the estimated tailings volume can also be used to determine the next candidate tail area.

[0033] Among them, the tailings discharge area generally includes the tailings storage area and the flood control and accumulation area; the tailings pond information includes the current information of the tailings pond, the design information of the tailings pond and the tailings discharge information of the tailings pond. Generally, the current information includes the current topographic map of the tailings pond and the current measured data of the tailings pond, the design information is the design stacking process and attached drawings of the tailings pond, and the tailings discharge information is the tailings discharge operation plan of the tailings pond. The spatial parameters of the candidate tailing discharge area include the current spatial parameters of the candidate tailing discharge area and the design spatial parameters that the candidate tailing discharge area needs to achieve. The combination of the two can calculate the tailings volume required for the simulated stacking of the candidate tailing discharge area.

[0034] Step S102, simulate the stacking of each candidate tailing area according to the estimated stacking sequence and the estimated stacking tailings volume, and obtain at least one selected tailing area and its stacking process height during the simulated stacking process.

[0035] In this embodiment, simulated stacking is performed on each candidate tail area according to the estimated stacking sequence and estimated stacking tailings volume of each candidate tail area, and at least one selected tail area and its stacking process height in the simulated stacking process are obtained.

[0036] Among them, the selected tail area is the candidate tail area where tailings are piled during the simulated stacking process, and the stacking process height is the tailings stacking height of the selected tail area during the simulated stacking process. Therefore, there can be multiple stacking process heights in the selected tail area.

[0037] Step S103, discretizing the longitudinal section of each selected row tail area after stacking into a plurality of equidistant elevation segments.

[0038] In this embodiment, the longitudinal sections of each selected row tail area after stacking are discretized into a plurality of equidistant elevation segments. The longitudinal sections of each selected row tail area after stacking may have irregular shapes, so it is necessary to partition and discretize the elevation segments according to the actual shapes of the longitudinal sections.

[0039] Step S104, calculates the estimated flood control storage capacity of the stacking process height in each selected tail area according to the acquisition order of each selected tail area, the volume of the corresponding equidistant elevation segments of each selected tail area and the current elevation flood control storage capacity table, and obtains the final estimated flood control storage capacity based on the estimated flood control storage capacity of the stacking process height in each selected tail area.

[0040] In this embodiment, according to the acquisition order of each selected tail area, the estimated flood control storage capacity of each selected tail area at the height of the stacking process is calculated in turn according to the volume of the corresponding equidistant elevation segment of each selected tail area and the current elevation flood control storage capacity table, and the estimated flood control storage capacity of the height of the stacking process in the last selected tail area is used as the final estimated flood control storage capacity. Among them, the current elevation flood control storage capacity table is the capacity before any stacking or transformation. In this way, by estimating the tail stacking of the tail area of ​​the tailings pond according to the tailings pond data, and estimating the flood control storage capacity according to the estimated tail stacking data and elevation discretization, the accuracy of the final estimated flood control storage capacity can be ensured.

[0041] It should be noted that the current flood control storage capacity corresponding to different elevations can be automatically calculated by the three-dimensional model software based on the lowest elevation around the flood discharge facilities in the current information of the tailings pond or the lowest elevation in the reservoir, and based on the preset water level step, or the current flood control storage capacity corresponding to different elevations can be approximately obtained by calculating the contour area of ​​the reservoir area corresponding to different elevations. Among them, the starting point of the current elevation in the current elevation flood control storage capacity table is the elevation of the lowest point in the reservoir in the current topographic map, and the highest point of the current elevation in the current elevation flood control storage capacity table is the elevation of the planned sub-dam in the tailings discharge operation plan.

[0042] See also Figure 2 In a specific embodiment, step S101 includes steps S1011 to S1021, and each step is described in detail below.

[0043] Step S1011, obtaining the current dam top elevation and the spatial parameters of each tail area according to the current information and the design information, and obtaining the total tail plan amount according to the tail information.

[0044] In this embodiment, the current dam top elevation is obtained from the current status information of the tailings pond. and the spatial parameters of each tailing area, and obtain the total tailing plan according to the tailing information in the tailing operation plan of the tailing pond Among them, the spatial parameters of the tail area include width data, height data, elevation data and slope ratio data.

[0045] Step S1012, determining the target sequence according to the design information.

[0046] It should be noted that the design information mainly refers to the tailings storage process. For example, if the tailing order of the design storage process in the design information is A, B, D, C area, then the target order is ABDC order.

[0047] See also Figure 3 , for example, for a four-sided dry storage tailings pond, the tailings pond includes a sub-dam area 301 and a tailings discharge area (a rolling area 302, a slag discharge area 303 and a flood control water accumulation area 304), and the designed storage process sequence is the rolling area 302, the slag discharge area 303 and the flood control water accumulation area 304, so the target sequence is the sequence of the rolling area, the slag discharge area and the flood control water accumulation area.

[0048] Step S1013, determining the i-th tail area to be determined from each tail area according to the target order, i≥1.

[0049] In this embodiment, the i-th tail area to be determined is determined from each tail area according to the target order, i≥1. The tail area to be determined is the object to be determined in the process of determining the candidate tail area. For example, if the target order is the order of rolling area, slag discharge area and flood control and water accumulation area, the first tail area to be determined is the rolling area, the second tail area to be determined is the slag discharge area, and the third tail area to be determined is the flood control and water accumulation area.

[0050] Step S1014, obtaining the target lowest point elevation of the ith tail area to be determined according to the current dam top elevation and the spatial parameters of the ith tail area to be determined.

[0051] In this embodiment, the target lowest point elevation of the ith tail area to be determined is calculated according to the current dam top elevation and the spatial parameters of the ith tail area to be determined.

[0052] Step S1015, obtaining the current lowest point elevation of the i-th tail area to be determined according to the current status information.

[0053] In this embodiment, the current lowest point elevation of the i-th tailings area to be determined is obtained according to the current information in the tailings pond current map.

[0054] Step S1016: if the target lowest point elevation is greater than the current lowest point elevation, the i-th tail area to be determined is taken as the j-th candidate tail area, j≥1; and the estimated tailings volume of the j-th candidate tail area is calculated according to the spatial parameters of the j-th candidate tail area.

[0055] In this embodiment, if the target lowest point elevation of the i-th to-be-determined tail area is greater than its current lowest point elevation, the i-th to-be-determined tail area is taken as the j-th candidate tail area. If there are two candidate tail areas at this time, j is 3 at this time; if the candidate tail area has not been determined at this time, j is 1 at this time. At the same time, the estimated tailings volume of the j-th candidate tail area is calculated based on the current lowest point elevation and target lowest point elevation of the j-th candidate tail area and other spatial parameters.

[0056] Step S1017, if the target lowest point elevation is less than or equal to the current lowest point elevation, then executing the step of determining the (i+1)th tail area to be determined from each candidate tail area according to the target order.

[0057] In this embodiment, if the target lowest point elevation of the i-th tail area to be determined is less than or equal to its current lowest point elevation, a step of determining the i+1-th tail area to be determined from each candidate tail area is performed according to the target order.

[0058] Step S1018, determining the tailings volumes and values ​​of the estimated tailings volumes corresponding to the 1st to jth candidate tailings areas.

[0059] In this embodiment, when the jth candidate tail region is obtained, the sum of the tailings volumes of the estimated tailings volumes corresponding to the first to jth candidate tail regions is determined. For example, when the second candidate tail region is obtained, the sum of the tailings volumes of the estimated tailings volume A corresponding to the first candidate tail region and the estimated tailings volume B corresponding to the second candidate tail region is determined.

[0060] Step S1019, if the tailings volume and value are less than the total tailings plan, a step of determining the i+1th tailing area to be determined from each tailing area according to the target sequence is executed.

[0061] In this embodiment, if the tailings volume and value are less than the planned tailings discharge total amount M, the process goes to step S1013 to perform a determination step on the i+1th tailings discharge area to be determined.

[0062] Step S1020, if the tailings volume and value is greater than or equal to the total tailings plan, then stop executing the step of determining the i+1th tailing area to be determined from each tailing area according to the target sequence.

[0063] In this embodiment, if the tailings volume and value is greater than or equal to the total tailings discharge plan M, the judgment step for the i+1th tailings discharge area to be judged is terminated, and no other candidate tailings discharge areas are determined. This is because the currently determined candidate tailings discharge areas and their estimated tailings volumes can meet the total tailings discharge plan in the tailings discharge plan.

[0064] Step S1021: The order of the candidate tail regions is used as the estimated stacking order.

[0065] In this embodiment, the order in which the candidate tail regions are obtained is used as the estimated stacking order. For example, if the candidate tail regions A and D are obtained in sequence, the estimated stacking order is the order of AD.

[0066] In a specific embodiment, the method further includes: if the sum of the tailings volumes of the estimated tailings volumes corresponding to all candidate tailings discharge areas is less than the total tailings discharge plan, then the sub-dam area of ​​the tailings pond is used as the initial tailings discharge area.

[0067] In this embodiment, if there are G tailing areas to be determined, the Gth tailing area to be determined is determined as the pth candidate tailing area, and the sum of the estimated tailing volumes corresponding to the 1st to pth candidate tailing areas is less than the total tailing plan, the sub-dam area of ​​the tailings pond is used as the initial tailing area. In this way, by increasing the tailing construction in the sub-dam area, the storage capacity of the future tailings pond can be more accurately reflected.

[0068] See also Figure 4 In a specific embodiment, step S102 includes steps S401 to S403, and each step is described in detail below.

[0069] Step S401, obtaining the designed sub-dam building height according to the design information, simulating the building of the initial tailing area according to the designed sub-dam building height, and determining the initial building tailings volume corresponding to the initial tailing area after the building.

[0070] In this embodiment, the design sub-dam stacking height is obtained according to the design information in the tailings pond design file, and the initial tailing area is simulated according to the design sub-dam stacking height, and the initial tailing volume corresponding to the initial tailing area after stacking is determined. At this time, the initial tailing area is the selected tailing area.

[0071] Step S402, determining the remaining tailings volume according to the total tailings discharge plan and the initial tailings volume.

[0072] In this embodiment, the difference between the total tailings discharge plan volume and the initial tailings volume is taken as the remaining tailings volume.

[0073] Step S403, based on the remaining tailings volume, the estimated stacking order and the estimated tailings volume corresponding to each candidate tail area, simulate the stacking of each candidate tail area to obtain at least one selected tail area and its stacking process height from the initial tail area and each candidate tail area.

[0074] In this embodiment, the tailings corresponding to the remaining tailings volume are simulated for each candidate tail area according to the estimated stacking order and the estimated tailings volume corresponding to each candidate tail area. In this simulated stacking process, the selected tail area for simulated stacking can be determined from each candidate tail area; and the stacking process height of each selected tail area can be obtained.

[0075] It should be noted that if the estimated tailings volumes of candidate tailing areas A, B, C, and D are 50, 60, 40, and 30, respectively, and the remaining tailings volume is 140, and the estimated stacking order is A, B, C, and D, then in the simulated stacking process, the remaining tailings of 140 are simulated stacked in the candidate tailing area A according to a volume of 50, and the remaining 90 tailings continue to be simulated stacked in the candidate tailing area B according to a volume of 60, and the remaining 30 tailings continue to be simulated stacked in the candidate tailing area C, and the remaining tailings volume is 0. At this time, the tailing areas are selected as the initial tailing areas and the candidate tailing areas A, B, and C.

[0076] In a specific embodiment, step S102 also includes: if the sum of the estimated tailings volumes corresponding to all candidate tail areas is greater than or equal to the total tail plan amount, then simulating the construction of each candidate tail area according to the total tail plan amount, the estimated construction order and the estimated tailings volumes corresponding to each candidate tail area; taking each candidate tail area as a selected tail area, and obtaining the construction process height of each selected tail area during the simulated construction process.

[0077] In this embodiment, if there are G tail areas to be determined, the Gth tail area to be determined is determined as the pth candidate tail area, and the sum of the tailings volumes of the estimated tailings volumes corresponding to the 1st to pth candidate tail areas is greater than or equal to the total tail area plan, then according to the estimated stacking order and the estimated tailings volumes corresponding to each candidate tail area, the tailings corresponding to the total tail area plan are used to simulate the stacking of each candidate tail area. At this time, each candidate tail area is selected as a tail area, and the stacking process height of each selected tail area in the simulated stacking process is obtained respectively.

[0078] See also Figure 5 In a specific embodiment, step S104 includes steps S1041 to S1045, and each step is described in detail below.

[0079] Step S1041, traversing N selected tail regions in sequence according to the order in which each selected tail region is obtained, where N≥1.

[0080] In this embodiment, all selected tail regions (N selected tail regions, N≥1) are traversed in sequence according to the order in which each selected tail region is acquired.

[0081] Step S1042, when traversing to the kth selected tail area, take at least one elevation segment that is smaller than the height of the stacking process among all equidistant elevation segments corresponding to the kth selected tail area as the elevation segment to be processed, 1≤k≤N; and calculate the sum of the volumes of all the elevation segments to be processed to obtain the sum value of the elevation segment volume.

[0082] In this embodiment, when traversing to the kth selected tail area, among all the equidistant elevation segments corresponding to the kth selected tail area, at least one elevation segment below the stacking process height in the kth selected tail area is taken as the elevation segment to be processed; and the sum of the volumes of all the elevation segments to be processed is calculated according to the shapes of each elevation segment to be processed to obtain the sum value of the elevation segment volume.

[0083] Step S1043, if k=1, the flood control storage capacity corresponding to the height of the stacking process in the kth selected tail area is determined according to the current elevation flood control storage capacity table; if k>1, the flood control storage capacity corresponding to the height of the stacking process in the kth selected tail area is determined according to the estimated flood control storage capacity corresponding to the k-1th selected tail area.

[0084] In this embodiment, if the current traversal is to the first selected tail area, the flood control storage capacity corresponding to the height of the stacking process in the first selected tail area is queried by difference in the current elevation flood control storage capacity table; if the current traversal is to the kth selected tail area, and k>1, the flood control storage capacity corresponding to the height of the stacking process in the k-1th selected tail area is queried by difference in the estimated flood control storage capacities corresponding to different stacking process heights in the k-1th selected tail area.

[0085] Step S1044, taking the difference between the flood control reservoir capacity and the volume sum of the elevation segments as the estimated flood control reservoir capacity corresponding to the height of the stacking process in the kth selected tail area.

[0086] In this embodiment, the flood control reservoir capacity corresponding to the height of the stacking process in the kth selected tail area is subtracted from the volume and value of the equidistant elevation segments below the height of the stacking process to obtain the estimated flood control reservoir capacity corresponding to the height of the stacking process in the kth selected tail area.

[0087] It should be noted that this process is a gradual deduction process, and each time the deduction is the part of the water storage capacity that has lost due to stacking or transformation. Through such calculations, it can be ensured that the remaining flood control storage capacity of the tailings pond can be accurately known at any stage, so as to reasonably plan and manage the water storage and use of the tailings pond in the future.

[0088] Step S1045, taking the estimated flood control storage capacity corresponding to the height of the stacking process in the Nth selected row tail area as the final estimated flood control storage capacity.

[0089] In this embodiment, the estimated flood control storage capacity corresponding to the height of the stacking process in the last selected tail area will no longer be reduced due to subsequent tailings stacking. The estimated flood control storage capacity corresponding to the height of the stacking process in the last selected tail area will be used as the final estimated flood control storage capacity. The final estimated flood control storage capacity at this time is the remaining storage capacity available for flood control after all planned stacking activities of the tailings pond are completed.

[0090] For example, for the sub-dam, compaction area, slag discharge area and flood control water accumulation area of ​​the four-sided dry storage tailings pond, when the first tailings discharge area to be determined is the compaction area, based on the existing dam top elevation h Calculate the target lowest point elevation of the rolling area based on the spatial parameters of the rolling area The calculation formula is as follows: , where is the width of the rolling area in the rolling area space parameters, It is the slope ratio of the rolling area in the spatial parameters of the rolling area.

[0091] Furthermore, if the target lowest point elevation of the rolling area is Greater than the current lowest elevation of the rolling area , then the judgment will be turned to the second tail area (slag discharge area) to be judged. If the target lowest point elevation of the rolling area is Greater than the current lowest elevation of the rolling area , the rolling area is taken as the candidate tailing area; and the volume of tailings piled corresponding to the rolling area is calculated , and determine the volume of tailings corresponding to the rolling area Is it greater than the total amount of the tail plan? ; If the volume of tailings piled corresponding to the rolling area If the tailing volume M is greater than or equal to the total tailing volume, then the candidate tailing area is only the rolling area, and the judgment of other tailing areas to be judged is stopped; if the tailing volume corresponding to the rolling area is If it is less than the total tailings plan M, the judgment will be transferred to the second tailings area to be judged (slag discharge area). Among them, the volume of tailings piled corresponding to the rolling area is The calculation formula is: , where It is the length of the rolling area in the rolling area space parameters.

[0092] Furthermore, when judging the second tail discharge area (slag discharge area), based on the current dam top elevation h Calculate the target lowest elevation of the slag discharge area based on the spatial parameters of the slag discharge area The calculation formula is as follows: , where is the width of the slag discharge area in the slag discharge area space parameters, It is the slope ratio of the slag discharge area in the spatial parameters of the slag discharge area.

[0093] Furthermore, if the target lowest point elevation of the slag discharge area is Greater than the current lowest elevation of the slag discharge area , then the judgment will be transferred to the third tail area to be judged (flood control water accumulation area). Greater than the current lowest elevation of the slag discharge area , then the slag discharge area is taken as the candidate tailings discharge area; and the volume of tailings piled corresponding to the slag discharge area is calculated , and determine the volume of tailings corresponding to the slag discharge area The volume of tailings piled corresponding to the rolling area Is the sum of the values ​​greater than the total amount of the tail plan? ; If the volume of tailings piled in the slag discharge area is The volume of tailings piled corresponding to the rolling area The sum of ) is greater than or equal to the total tailing plan M, then the candidate tailing areas are only the rolling area and the slag discharge area, and the judgment of other tailing areas to be judged is stopped. At this time, the estimated stacking order is the rolling area and the slag discharge area; if the tailings volume corresponding to the slag discharge area The volume of tailings piled corresponding to the rolling area The sum of ) is less than the total tailings plan M, then the judgment will be transferred to the third tailings area to be judged (flood control and accumulation area). Among them, the volume of tailings piled corresponding to the slag discharge area is The calculation formula is: , where It is the length of slag discharge area in the slag discharge area space parameters.

[0094] Furthermore, when judging the third tail area to be judged (flood control and accumulation area), the target lowest point elevation of the slag discharge area is Subtract the step height to get the target lowest point elevation of the flood control and waterlogging area .

[0095] Furthermore, if the target lowest point elevation of the floodplain is adjusted Greater than the current lowest elevation of the flood control waterlogging area , then there is no need to perform tail discharge for the third tail discharge area (flood control waterlogging area). Greater than the current lowest elevation of the flood control waterlogging area , the flood control waterlogging area is taken as the candidate tailing area; and the volume of tailings piled corresponding to the flood control waterlogging area is calculated , and determine the volume of tailings piled corresponding to the flood control and accumulation area , the volume of tailings piled corresponding to the slag discharge area The volume of tailings piled corresponding to the rolling area Is the sum of the values ​​greater than the total amount of the tail plan? ; If the volume of tailings piled up in the flood control area , the volume of tailings piled corresponding to the slag discharge area The volume of tailings piled corresponding to the rolling area The sum of ) is greater than or equal to the total tailings volume M, then the estimated order of stacking in the candidate slag discharge area is the rolling area, slag discharge area and flood control water accumulation area; if the tailings volume corresponding to the flood control water accumulation area is , the volume of tailings piled corresponding to the slag discharge area The volume of tailings piled corresponding to the rolling area The sum of ) is less than the total tailings discharge plan M, the sub-dam area of ​​the tailings pond is used as the initial tailings discharge area. At this time, the estimated stacking order of the candidate slag discharge area is still the rolling area, slag discharge area and flood control water accumulation area, but the simulated stacking order in the subsequent simulation stacking process is the sub-dam area, rolling area, slag discharge area and flood control water accumulation area. Among them, the tailings volume corresponding to the flood control water accumulation area is The calculation formula is: , where It is the length of the flood control waterlogging area in the spatial parameters of the flood control waterlogging area.

[0096] Furthermore, if the selected tail area is the sub-dam area, rolling area, slag discharge area and flood control water accumulation area in sequence, the selected tail area after each construction is divided into zones and discretized. Specifically, for the construction area of ​​the sub-dam area, it is discretized into multiple equidistant elevation segments with the same height difference from the dam bottom to the dam top; for the construction areas of the rolling area and the slag discharge area, the longitudinal section is divided into multiple different calculation areas, and each area is longitudinally discretized into multiple equidistant elevation segments with the same height difference; the flood control water accumulation area is discretized into multiple equidistant elevation segments with the same height difference from the reservoir bottom to the top of the flood control water accumulation area.

[0099] Furthermore, for the rolling area, the area of ​​each equidistant elevation segment longitudinal section is calculated using the area calculation formulas of trapezoidal section, triangular section, etc. according to the shape of each partition; the length of the rolling area is calculated according to the following formula: , where is the length of the dam axis. For a dry-stack tailings pond with four sides, L is the total length of the dam axis on all four sides, in meters. is the total length of the rolling area, unit (m); The distance from the midpoint of the compaction area to the dam axis, in meters; the volume of each equidistant elevation segment is obtained by multiplying the longitudinal section area of ​​each equidistant elevation segment by the total length of the compaction area; the sum of the volumes of all elevation segments below the stacking process height is calculated; the flood control storage capacity corresponding to the stacking process height is obtained by checking or interpolating from the elevation-estimated flood control storage capacity list 1; the estimated flood control storage capacity corresponding to the stacking process height is obtained by subtracting the sum of the volumes of all elevation segments below the stacking process height from the flood control storage capacity corresponding to the stacking process height. The elevation-estimated flood control storage capacity list 2 is obtained based on the estimated flood control storage capacity corresponding to different stacking process heights.

[0100] Furthermore, for the slag discharge area, the calculation steps for the sum of the volumes of all elevation sections below the stacking process height in the slag discharge area are the same as those for the rolling area. The flood control reservoir capacity corresponding to the stacking process height is obtained by querying or interpolating from the elevation-estimated flood control reservoir capacity list 2; the estimated flood control reservoir capacity corresponding to the stacking process height is deducted from the sum of the volumes of all elevation sections below the stacking process height, which is the estimated flood control reservoir capacity corresponding to the stacking process height. According to the estimated flood control reservoir capacity corresponding to different stacking process heights, the elevation-estimated flood control reservoir capacity list 3 is obtained.

[0101] Furthermore, for the flood control water storage area, the calculation steps for the sum of the volumes of all elevation sections below the stacking process height in the flood control water storage area are the same as those for the sub-dam area. The flood control storage capacity corresponding to the stacking process height is obtained by querying or interpolating from the elevation-estimated flood control storage capacity list 3; the estimated flood control storage capacity corresponding to the stacking process height is deducted from the sum of the volumes of all elevation sections below the stacking process height from the flood control storage capacity corresponding to the stacking process height. The elevation-estimated flood control storage capacity list 4 is obtained based on the estimated flood control storage capacity corresponding to different stacking process heights.

[0102] Furthermore, the elevation-estimated flood control storage capacity list 4 is used as the final estimated flood control storage capacity of the four-sided dry storage tailings pond. Figure 7 shown.
