[0002] Tailings ponds are places where tailings are discharged after metal and non-metallic mine ores are sorted. They are important facilities to ensure the mining of mineral resources. The safety of tailings ponds directly affects the safety of people's lives and property.

[0003] Tailings ponds must store tailings in accordance with the design. The amount of tailings entering the pond must be reasonably controlled.

[0004] At present, the management method of tailings pond capacity is relatively simple, and there is no accurate detection of tailings slurry flow, tailings slurry concentration, tailings particle size, etc. of the tailings entering the pond, and thus it is impossible to accurately calculate the storage capacity utilization coefficient, dam rising speed, etc., and it is impossible to reasonably control the amount of tailings entering the pond.

[0071] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0072] The idea of ​​the present application is to detect the indicators of tailings during the process of tailings being discharged into the tailings pond to calculate the annual required dam rising speed, and to reasonably adjust the tailings discharge according to the annual required dam rising speed, thereby improving the comprehensive management effect of the mine tailings pond.

[0073] The present application is described in detail below through specific embodiments.

[0074] Figure 1 The flowchart of the non-coal mine tailings storage capacity management method proposed in one embodiment of the present application is shown. Figure 1 As shown, the method of this embodiment includes steps S110 to S130:

[0075] Step S110, determining the effective storage capacity corresponding to different elevations based on the three-dimensional data of the tailings pond and the effective utilization coefficient, and forming an elevation-effective storage capacity relationship diagram.

[0076] The tailings pond has detailed design parameters when it is designed, and has an actual topographic map after it is built. Therefore, the size data of the tailings pond can be determined by obtaining the design parameters when the tailings pond is designed, or by scanning the topographic map after the tailings pond is built, or by combining the design parameters and the topographic map to determine the size data of the tailings pond. The size data of the tailings pond is three-dimensional data, which can include but is not limited to the elevation of the tailings pond, the area corresponding to each elevation of the tailings pond, the height difference between adjacent elevations of the tailings pond, etc.

[0077] The area corresponding to each elevation of the tailings pond can be used to determine the average area between adjacent elevations. The volume corresponding to adjacent elevations can be determined by using the average area between adjacent elevations and the height difference between adjacent elevations. As the elevation of the tailings pond is accumulated, the total storage capacity corresponding to different elevations of the tailings pond can be determined.

[0078] The effective storage capacity corresponding to different elevations of the tailings pond and the effective utilization coefficient can be used to determine the effective storage capacity corresponding to different elevations of the tailings pond. In the process of accumulating tailings in the tailings pond, it is impossible to effectively fill all the total storage capacity. Therefore, the effective utilization coefficient is used to indicate the ratio of the effective storage capacity that can actually be filled to the total storage capacity. The effective utilization coefficient is a value that can be adjusted as the tailings accumulate. When designing and constructing the tailings pond, since there is no actual test value of the dry bulk density of the tailings accumulation, an initial effective utilization coefficient can be provided based on experience. The initial effective utilization coefficient can be small when the elevation of the tailings pond is low, and gradually increase as the elevation of the tailings pond increases. As tailings gradually accumulate in the tailings pond, when the accumulated tailings reach a certain value, the dry bulk density of the accumulated tailings can be tested. Based on the detected dry bulk density of the tailings accumulation, the amount of tailings entering the pond, the corresponding elevation corresponding to the amount of tailings entering the pond, and the corresponding total storage capacity corresponding to the corresponding elevation, the initial effective utilization coefficient is re-corrected. The total storage capacity corresponding to different elevations is multiplied by the corresponding effective utilization coefficient to obtain the effective storage capacity corresponding to different elevations.

[0079] The effective storage capacity corresponding to different elevations can be plotted in a coordinate system with storage capacity as the horizontal axis and elevation as the vertical axis to form an elevation-effective storage capacity relationship diagram. Of course, the total storage capacity corresponding to different elevations can also be plotted in a coordinate system with storage capacity as the horizontal axis and elevation as the vertical axis to form an elevation-effective storage capacity / total storage capacity relationship diagram.

[0080] Step S120, during the process of tailings being discharged into the tailings pond, the indicators of the tailings entering the pond are tested, and the effective storage capacity required for the year is determined based on the test results.

[0081] In the process of tailings being discharged into the tailings pond, the indicators of the tailings entering the pond can be tested. The indicators may include but are not limited to: tailings slurry flow, tailings slurry concentration, tailings particle size, tailings specific gravity, tailings volume entering the pond, dry bulk density of tailings accumulation, etc. The above indicators of the tailings entering the pond can be tested regularly or periodically, or the above indicators of the tailings entering the pond can be tested continuously. That is, during the test, the above indicators of the tailings entering the pond for a specific period of time can be tested regularly. The specific period of time may include but is not limited to one week, one month, one quarter, one year, etc.

[0082] When detecting the amount of tailings entering the warehouse within a specific period of time, the amount of tailings entering the warehouse within a specific period of time can be directly detected, or the amount of tailings entering the warehouse within a specific period of time can be calculated through the tailings slurry flow and tailings slurry concentration within a specific period of time. When detecting the dry bulk density of tailings accumulation of tailings entering the warehouse within a specific period of time, the dry bulk density of tailings accumulation can be directly detected after the accumulated tailings reach a certain value, or the dry bulk density of tailings accumulation can be inferred through the tailings particle size when the accumulated tailings do not reach a certain value.

[0083] Based on the tailings volume and dry bulk density of tailings stored in the specific time period detected above, the required effective storage capacity of tailings stored in the specific time period can be determined. Based on the required effective storage capacity for the specific time period, the required effective storage capacity for the year is calculated. For example, the required effective storage capacity for the year can be inferred from the required effective storage capacity of tailings stored in the first quarter of the year.

[0084] Step S130, determining the annual required dam raising speed according to the annual required effective storage capacity, the relationship diagram and the benchmark storage beach top elevation. When the annual required dam raising speed is greater than the designed raising speed, adjusting the tailings discharge plan.

[0085] The management of tailings ponds can be, but is not limited to, conducted on an annual basis. Therefore, at the end of the previous year, the elevation of the tailings pond's storage beach top can be recorded as the benchmark storage beach top elevation. The tailings discharge in the current year continues from the previous year's benchmark storage beach top elevation. From the elevation-effective storage capacity relationship diagram drawn, determine the effective storage capacity starting point corresponding to the benchmark storage beach top elevation; after adding the annual required effective storage capacity from the effective storage capacity starting point, determine the effective storage capacity end point; from the elevation-effective storage capacity relationship diagram drawn, determine the annual required beach top elevation corresponding to the effective storage capacity end point; the difference between the annual required beach top elevation and the benchmark storage beach top elevation is the annual required dam rise height. The annual required dam rise speed can be determined by the annual required dam rise height and one year.

[0086] During the tailings accumulation process, the annual required dam rise speed shall not be higher than the design rise speed. Once the annual required dam rise speed is higher than the design rise speed, it will not only shorten the service life of the tailings pond, but also may affect the safety performance of the tailings pond and increase the probability of accidents such as leakage in the tailings pond. Therefore, when the annual required dam rise speed is higher than the design rise speed, it is necessary to adjust the tailings discharge plan and slow down or suspend tailings discharge.

[0087] The tailings discharge plan may include, but is not limited to, real-time tailings discharge, daily tailings discharge, monthly tailings discharge, quarterly tailings discharge, annual tailings discharge, etc. The tailings discharge plan is adjusted to reduce the required dam rise speed to no more than the design rise speed in the current year, thereby ensuring the continued safe and stable use of the tailings pond.

[0088] from Figure 1 It can be seen from the method shown that the non-coal mine tailings pond capacity management method provided by the present application determines the effective storage capacity corresponding to different elevations based on the three-dimensional data of the tailings pond and the effective utilization coefficient, and forms an elevation-effective storage capacity relationship diagram; in the process of tailings being discharged into the tailings pond, the indicators of the tailings entering the pond are detected, and the effective storage capacity required for the year is determined based on the detection results; the annual required dam rise speed is determined based on the annual required effective storage capacity, the relationship diagram and the benchmark storage beach top elevation, and when the annual required dam rise speed is greater than the designed rise speed, the tailings discharge plan is adjusted. The non-coal mine tailings pond capacity management method provided by the present application accurately detects the indicators of the tailings entering the pond, determines the annual required dam rise speed based on the detection results, and when the annual required dam rise speed is greater than the designed rise speed, the tailings discharge plan is adjusted to control it, thereby achieving the goal of intelligent management of mine tailings ponds.

[0089] In some embodiments of the present application, in the above method, step S110, based on the three-dimensional data of the tailings pond and the effective utilization coefficient, determines the effective storage capacity corresponding to different elevations, and forms an elevation-effective storage capacity relationship diagram, including: performing a three-dimensional scan on the topographic map of the tailings pond to determine the three-dimensional data; determining the total storage capacity corresponding to different elevations based on the three-dimensional data; determining the effective storage capacity corresponding to different elevations based on the total storage capacity and the effective utilization coefficient, and forming a relationship diagram.

[0090] In this embodiment, the three-dimensional data of the tailings pond is obtained and determined by scanning and identifying the actual topographic map of the tailings pond. The three-dimensional data of the tailings pond may include the initial dam crest elevation, initial dam height, initial dam crest width, initial dam crest length, initial dam upstream side slope gradient, initial dam downstream side slope gradient, tailings dam elevation, tailings dam height, tailings dam outer slope gradient, etc.

[0091] The total storage capacity corresponding to different elevations can be determined, but is not limited to, at 10-meter intervals. That is, the area corresponding to the elevation is determined every 10 meters, and then the average area between adjacent elevations is determined, so as to calculate the volume corresponding to the adjacent 10-meter interval elevations. As the elevation of the tailings pond accumulates the above volume, the total storage capacity corresponding to different elevations of the tailings pond can be determined.

[0092] For the effective utilization coefficient, when the accumulated tailings have not reached a certain value, the initial effective utilization coefficient can be used. The initial effective utilization coefficient can be 0.4 in the initial dam stage. As the tailings dam elevation increases, the initial effective utilization coefficient can gradually increase, such as gradually rising to 0.5, 0.6, 0.7, and finally reaching 0.75. As the tailings are discharged into the tailings pond, after the accumulated tailings in the tailings pond reach a certain value, the actual dry bulk density of the tailings entering the pond can be detected, so as to determine a more accurate effective utilization coefficient based on the amount of tailings entering the pond, the dry bulk density of the tailings accumulation, the corresponding elevation corresponding to the amount of tailings entering the pond, and the corresponding total storage capacity corresponding to the corresponding elevation, and then correct the initial effective utilization coefficient. In other words, the effective utilization coefficient is not static, it is continuously updated based on the test results as the tailings are discharged into the tailings pond. The effective utilization coefficient can be updated in units of years, but is not limited to.

[0093] According to the multiplication result of the total storage capacity corresponding to different elevations and the effective utilization coefficient corresponding to different elevations, the effective storage capacity corresponding to different elevations is determined, and then the elevation-effective storage capacity, or elevation-effective storage capacity / total storage capacity relationship diagram is obtained.

[0094] In some embodiments of the present application, in the above method, step S120, discharging tailings into a tailings pond, includes: determining a tailings discharge plan according to a mineral processing production plan; and discharging the tailings into a tailings pond according to the tailings discharge plan.

[0095] In this embodiment, a corresponding tailings discharge plan is formulated through the ore dressing production plan of the mine dressing plant. The tailings discharge plan includes at least the scheduled tailings discharge amount, such as the real-time tailings discharge amount, the daily tailings discharge amount, the monthly tailings discharge amount, the quarterly tailings discharge amount, the annual tailings discharge amount, etc. The scheduled tailings discharge amount can be, but is not limited to, a fixed value or a fixed range.

[0096] According to the tailings discharge plan, the tailings are discharged into the tailings pond. In this embodiment, the tailings discharge plan is formulated based on the mineral processing production plan. When the tailings discharge plan is adjusted, the mineral processing production plan needs to be taken into account at the same time. That is, the adjusted tailings discharge plan still meets the requirements of the mineral processing production plan, or when the adjusted tailings discharge plan cannot meet the requirements of the mineral processing production plan, the mineral processing production plan is adjusted.

[0097] In some embodiments of the present application, in the above method, step S120, the indicators of the tailings entering the storage are detected, and the annual effective storage capacity required is determined based on the detection results, including: detecting the tailings slurry flow, tailings slurry concentration, and dry bulk density of the tailings within a certain period of time; determining the amount of tailings entering the storage within a certain period of time based on the tailings slurry flow and the tailings slurry concentration; determining the required effective storage capacity within a certain period of time based on the amount of tailings entering the storage and the dry bulk density of the tailings; determining the annual required effective storage capacity based on the required effective storage capacity within a certain period of time.

[0098] In this embodiment, the tailings slurry flow rate and tailings slurry concentration of the tailings within a certain period of time are detected to determine the amount of tailings entering the warehouse within a certain period of time. The amount of tailings entering the warehouse within a certain period of time can be determined by the product of the tailings slurry flow rate and the tailings slurry concentration of the tailings within a certain period of time. The certain period of time can be, but is not limited to, a week, a month, a quarter, a year, etc. For example, the tailings slurry flow rate and the tailings slurry concentration can be continuously detected during the process of the tailings being discharged into the tailings pond. When the tailings are discharged into the tailings pond for one week in the year, the amount of tailings entering the warehouse within a week is calculated by the product of the tailings slurry flow rate and the tailings slurry concentration within a week; or, when the tailings are discharged into the tailings pond for one month in the year, the amount of tailings entering the warehouse within a month is calculated by the product of the tailings slurry flow rate and the tailings slurry concentration within a month, etc.

[0099] In some optional embodiments, the dry bulk density of tailings accumulation within a certain period of time is detected, including: when the tailings accumulated in the tailings pond is less than a preset value, the tailings particle size of the tailings within a certain period of time is detected; based on the tailings particle size within a certain period of time, the dry bulk density of the tailings accumulation within a certain period of time is determined; when the tailings accumulated in the tailings pond is not less than a preset value, the dry bulk density of the tailings accumulation within a certain period of time is directly detected.

[0100] When the tailings accumulated in the tailings pond are less than the preset value, the dry bulk density of the tailings accumulation cannot be directly detected. At this time, the dry bulk density of the tailings accumulation is estimated by detecting the tailings particle size. When the tailings accumulated in the tailings pond are not less than the preset value, the actual dry bulk density of the tailings accumulation can be directly detected. The required effective storage capacity within a certain period of time is determined by dividing the amount of tailings entering the storage within a certain period of time by the dry bulk density of the tailings accumulation. For example, the required effective storage capacity within a quarter can be determined by combining the amount of tailings entering the storage within a quarter and the dry bulk density of the tailings accumulation within that quarter.

[0101] Since the tailings indicators are not prone to rapid and large fluctuations during the tailings discharge process, the annual effective storage capacity required can be estimated based on the effective storage capacity required within a certain period of time. For example, the effective storage capacity required for the year can be estimated based on the effective storage capacity required within a quarter.

[0102] In some embodiments of the present application, in the above method, step S130, according to the annual required effective storage capacity, the relationship diagram and the benchmark storage beach top elevation, determines the annual required dam rising speed, and when the annual required dam rising speed is greater than the design rising speed, adjusts the tailings discharge plan, including: in the relationship diagram, taking the benchmark storage beach top elevation as the starting point, determining the height change value corresponding to the annual required effective storage capacity; determining the annual required dam rising speed according to the height change value; when the annual required dam rising speed is greater than the design rising speed, reducing the annual tailings discharge amount in the tailings discharge plan.

[0103] In this embodiment, the elevation of the top of the tailings pond at the end of the previous year is used as the benchmark top elevation of the tailings pond. From the elevation-effective storage capacity relationship diagram, the effective storage capacity corresponding to the benchmark top elevation of the tailings pond is used as the starting point to find the end point of the effective storage capacity after the effective storage capacity required for the year is added, so as to determine the difference between the elevation end point corresponding to the effective storage capacity end point and the benchmark top elevation of the tailings pond as the height change value, which is the annual dam rise height. According to the quotient of the annual dam rise height and the time of one year, the required dam rise speed for the year is determined.

[0104] When the annual required dam rising speed is higher than the design rising speed, the annual tailings discharge in the tailings discharge plan is reduced, thereby slowing down the annual required dam rising speed and reducing the annual required dam rising speed to below the design rising speed.

[0105] In some embodiments of the present application, in the above method, step S120, detecting the indicators of the tailings entering the warehouse, also includes: detecting the indicators, comparing the detection results with the designed storage parameters, and taking corresponding disposal measures according to different comparison results.

[0106] In the process of tailings being discharged into the tailings pond, in addition to ensuring the safe use of the tailings pond by monitoring the annual required dam rise speed, it is also necessary to monitor whether the indicators of the tailings entering the pond can meet the design requirements of the tailings pond. That is, the indicators of the tailings are tested to determine whether the test results meet the design entry parameters. If the test results do not meet the design entry parameters, it is necessary to take corresponding disposal measures based on the indicators and / or the deviation between the test results and the design entry parameters. Testing the indicators of the tailings may include, but is not limited to: testing the flow rate of the tailings slurry to determine whether the flow rate of the tailings slurry meets the design entry parameters; testing the outlet temperature of the tailings slurry to determine whether the outlet temperature of the tailings slurry meets the design entry parameters; testing the concentration of the tailings slurry to determine whether the concentration of the tailings slurry meets the design entry parameters; testing the particle size of the tailings to determine whether the particle size of the tailings meets the design entry parameters, etc.

[0107] In some optional embodiments, the indicators are tested, the test results are compared with the designed storage parameters, and corresponding disposal measures are taken according to different comparison results, including: using an online monitoring flow meter installed on the tailings conveying pipeline to test the tailings slurry flow; or, obtaining the mill flow and the concentrate slurry flow, and determining the tailings slurry flow according to the mill flow and the concentrate slurry flow; determining the tailings slurry flow rate according to the flow test results or the determined tailings slurry flow, and suspending the discharge of tailings when the tailings slurry flow rate is lower than the designed flow rate.

[0108] The tailings slurry flow rate is detected online in real time or manually. The detection method may include installing an online monitoring flow meter on the tailings conveying pipeline, and obtaining the tailings slurry flow rate by reading the reading of the online monitoring flow meter. The detection method may also include calculating the tailings slurry flow rate by using the difference between the mill flow rate and the concentrate slurry flow rate. The tailings slurry flow rate can be determined based on the tailings slurry flow rate and the cross-sectional area of ​​the tailings conveying pipeline.

[0109] The design flow rate of the tailings pond is used to indicate the critical value of the tailings slurry flow rate. When the tailings slurry flow rate is lower than the critical value, the tailings conveying pipeline is prone to blockage. Therefore, when the tailings slurry flow rate is lower than the design flow rate, the discharge of tailings is suspended and resumed after the problem is resolved.

[0110] In some optional embodiments, the indicators are tested, the test results are compared with the designed storage parameters, and corresponding disposal measures are taken according to different comparison results, including: using an online monitoring concentration meter installed on the tailings conveying pipeline to test the tailings slurry concentration; or, obtaining the mill flow, mill concentration, concentrate slurry flow and concentrate slurry concentration, and determining the tailings slurry concentration based on the mill flow, mill concentration, concentrate slurry flow and concentrate slurry concentration; when the tailings slurry concentration is higher than the designed maximum concentration, suspending the discharge of tailings; when the tailings slurry concentration is lower than the designed minimum concentration, inspecting the return water facilities.

[0111] The concentration of tailings slurry is detected online in real time or manually. The detection method may include installing an online monitoring concentration meter on the tailings conveying pipeline, and obtaining the concentration of tailings slurry by reading the reading of the online monitoring concentration meter. The detection method may also include calculating the concentration of tailings slurry using mill flow and mill concentration, concentrate slurry flow and concentrate slurry concentration.

[0112] The design concentration of the tailings pond is used to indicate the concentration range of the tailings slurry. The design concentration includes the design maximum concentration and the design minimum concentration. When the tailings slurry concentration is higher than the design maximum concentration (for example, the design maximum concentration is 35%, and the tailings slurry concentration is higher than 35%), it will affect the tailings classification and dam structure when the impact dam is formed. Therefore, when the tailings slurry concentration is higher than the design maximum concentration, the discharge of tailings is suspended and resumed after the problem is resolved. When the tailings slurry concentration is lower than the design minimum concentration, the capacity of the backwater facilities needs to be checked to confirm whether the backwater facilities meet the requirements.

[0113] In some optional embodiments, the indicators are tested, the test results are compared with the designed storage parameters, and corresponding disposal measures are taken according to different comparison results, including: using an online particle size analyzer installed on the tailings conveying pipeline to test the tailings particle size; or, obtaining the monitoring results of the mill particle size analyzer, and determining the tailings particle size according to the test results of the mill particle size analyzer; when the deviation between the tailings particle size and the designed particle size exceeds a first preset threshold, increasing the number of tests; when the deviation between the tailings particle size and the designed particle size exceeds a second preset threshold, suspending the discharge of tailings.

[0114] The particle size of the tailings is detected online in real time or manually. The detection method may include installing an online particle size analyzer on the tailings conveying pipeline, and obtaining the particle size of the tailings by reading the detection results of the online particle size analyzer. Since there is less concentrate in the original ore, the tailings yield can generally reach more than 90%, so the detection method may also include using the detection results of the mill particle size analyzer as the tailings particle size.

[0115] The first preset threshold can be 5%. When the tailings particle size test result deviates from the design particle size by more than 5%, it means that there is a difference between the tailings particle size and the design particle size, but the difference is not large. At this time, the number of tests can be increased and the reasons can be analyzed to solve the existing problems in time. The second preset threshold can be 10%. When the tailings particle size test result deviates from the design particle size by more than 10%, it means that the tailings particle size is too different from the design particle size. At this time, the discharge of tailings needs to be suspended and resumed after the problem is solved.

[0116] In some optional embodiments, the indicators are tested, the test results are compared with the designed storage parameters, and corresponding disposal measures are taken according to different comparison results, including: using a thermometer installed on the tailings conveying pipeline to test the tailings outlet temperature; when the tailings outlet temperature is lower than the designed temperature, suspending the discharge of tailings.

[0117] The tailings outlet temperature is detected online in real time or manually. The detection method may include installing a thermometer on the tailings conveying pipeline and obtaining the tailings outlet temperature by reading the detection result of the thermometer.

[0118] When the tailings outlet temperature is lower than the design temperature, freezing pipes are prone to occur. Therefore, once the tailings outlet temperature is detected to be lower than the design temperature, the discharge of tailings needs to be suspended and the discharge can be resumed after the temperature rises to meet the requirements.

[0119] In some embodiments of the present application, in the above method, in step S110, the effective utilization coefficient is determined by the following method: providing an initial effective utilization coefficient; in the process of tailings being discharged into the tailings pond, analyzing the historical indicators of the tailings entering the pond at preset time intervals, and determining the historical effective storage capacity based on the analysis results; based on the three-dimensional data, determining the historical total storage capacity according to the elevation corresponding to the preset time interval; correcting the initial effective utilization coefficient according to the historical effective storage capacity and the historical total storage capacity to obtain the effective utilization coefficient.

[0120] In this embodiment, in order to obtain a more accurate elevation-effective storage capacity relationship diagram, the effective utilization coefficient is regularly updated during the process of tailings being discharged into the tailings pond. In the early stage of design, construction and use of the tailings pond, since there is no actual test value of the dry bulk density of the tailings accumulation, an initial effective utilization coefficient is provided based on experience. The initial effective utilization coefficient may gradually increase with the increase of elevation. The preset time interval may be a fixed time such as a week, a month, a quarter, a year, or the corresponding time for the fixed value of the elevation of the top of the storage beach of the tailings pond.

[0121] Taking the preset time interval of one year as an example, at the end of the year, the historical indicators of the tailings stored in the warehouse that year are analyzed. The historical indicators include at least the dry bulk density of the tailings accumulation and the amount of tailings stored in the warehouse. The historical indicators can also include but are not limited to tailings slurry flow, tailings slurry concentration, tailings particle size, etc. The historical effective storage capacity of the tailings stored in the warehouse that year can be determined by the amount of tailings stored in the warehouse and the dry bulk density of the tailings accumulation. Based on the three-dimensional data obtained by three-dimensional scanning of the topographic map of the tailings pond, the total storage capacity corresponding to different elevations of the tailings pond can be determined. At this time, the historical total storage capacity of the tailings stored in the warehouse that year can be calculated using the elevation of the top of the storage beach of the tailings pond at the end of the previous year and the elevation of the top of the storage beach of the tailings pond at the end of the current year. The effective utilization coefficient corresponding to the tailings stored in the warehouse that year can be obtained by dividing the historical effective storage capacity with the historical total storage capacity. The effective utilization coefficient corresponding to the tailings stored in the current year corresponds to the elevation from the top of the storage beach of the tailings pond at the end of the previous year to the top of the storage beach of the tailings pond at the end of the current year. Therefore, the effective utilization coefficient corresponding to the tailings stored in the current year is used to correct the initial effective utilization coefficient. When correcting, in addition to correcting the initial effective utilization coefficient corresponding to the elevation from the top of the storage beach of the tailings pond at the end of the previous year to the top of the storage beach of the tailings pond at the end of the current year, the initial effective utilization coefficient corresponding to the top of the storage beach of the tailings pond higher than the top of the storage beach of the tailings pond at the end of the current year is adjusted accordingly.

[0122] Take the preset time interval as the corresponding time for the fixed value increase of the top elevation of the tailings pond as an example. For example, when the fixed value is increased by 10 meters, the historical indicators of the tailings within the 10 meters are analyzed to determine the historical effective storage capacity of the tailings entering the pond by increasing the elevation corresponding to the 10 meters. The historical total storage capacity of the tailings entering the pond is calculated using the elevation corresponding to the increase of 10 meters. The effective utilization coefficient corresponding to the tailings entering the pond can be obtained by dividing the historical effective storage capacity by the historical total storage capacity. The initial effective utilization coefficient is corrected using the effective utilization coefficient corresponding to the tailings entering the pond. When correcting, in addition to correcting the initial effective utilization coefficient corresponding to the increase of the 10-meter elevation, the initial effective utilization coefficient corresponding to the elevation higher than the top elevation of the storage pond is adjusted accordingly.

[0123] In some embodiments of the present application, the above method further includes: determining the future service life of the tailings pond based on the tailings discharge plan, the dry bulk density of the tailings accumulation and the relationship diagram.

[0124] In this embodiment, although the future service life of the tailings pond may be predicted during its design and construction, the prediction is usually based on a reference provided by experience. As the tailings are discharged into the tailings pond, the actual dry bulk density of the tailings accumulation can be detected, the effective utilization coefficient can be corrected, etc., so that the future service life of the tailings pond can be more accurately determined or adjusted.

[0125] According to the tailings discharge plan, the future annual tailings discharge can be determined. Based on the detection of the dry bulk density of the tailings pile and the future annual tailings discharge, the future annual effective tailings storage capacity can be determined. According to the future annual effective tailings storage capacity and the relationship diagram drawn using the timely revised and updated effective utilization coefficient, the future annual tailings rise height can be determined. Furthermore, according to the future annual tailings rise height, combined with the tailings dam elevation of the tailings pond, the future service life of the tailings pond can be determined.

[0126] The non-coal mine tailings pond capacity management method proposed in this application is described in detail below through a specific embodiment.

[0127] A tailings pond of a metal mine is located in the eastern part of the Qinling Mountains, which is a low-to-middle mountain area of ​​the Waifang Mountain System. The tailings pond is generally tree-shaped with lush vegetation. The initial dam is located in the northern part of the site, with a narrow gully mouth and a V-shaped valley. There are many bedrock faults at the tailings pond site, all of which are normal faults. All faults have not entered the Quaternary slope and alluvial gravel soil, so they are all non-homo-new active faults and have no impact on the construction of the tailings pond. The covering layer is mainly slope, alluvial gravel soil, alluvial silty clay, and pebbles, and the lower part is Ordovician granite and Upper Proterozoic andesite.

[0128] The foundation of the initial dam is composed of moderately weathered andesite. The bedrock of the east dam shoulder is exposed, the Quaternary and strongly weathered layers are thin, the mountain slope is about 30°, and the main joints are inclined at an angle of 60° to the slope. The combination of structural planes is beneficial to the stability of the slope. The Quaternary gravel layer on the west dam shoulder is 0.5-5.0m thick, the mountain slope is about 22°, the main joints are inclined at an angle of 90° to the slope, and the combination of structural planes is beneficial to the stability of the slope. The foundation of the auxiliary dam is moderately weathered granite, and the slope of the dam shoulders on both sides is about 20°, which is overall stable. The thickness of the pebbles above the cut-off dam is 0.5-6.4m, and the lower part is moderately weathered andesite.

[0129] The initial dam crest elevation is 720m, the initial dam height is 75m, and it can store 1.3 years of tailings from mining production. The initial dam crest width is 5m, the upstream slope of the dam body is 1:2.0, the downstream slope of the dam body is 1:2.0, the dam crest length is 258m, and the dam body engineering volume is about 1.458 million m 3 After the initial dam was full, the tailings upstream method was used to hydraulically fill the dam. The average slope of the tailings dam was 1:5.0, the tailings dam elevation was 840m, the tailings dam height was 120m, the total tailings pond height was 195m, and the total tailings pond capacity was 124 million m 3 The tailings pond is a second-class pond, covering an area of ​​approximately 2.396 million m 2 The initial effective utilization coefficient of the tailings pond was 0.4 in the early stage, and gradually increased to 0.5, 0.6, 0.7, and 0.75 in the middle and late stages, and finally formed an effective storage capacity of 93.03 million m 3 .

[0130] The dam is built by tailings hydraulic filling method. The sub-dam is built by tailings. The sub-dam is 2.5m high and 3m wide at the top. The upstream and downstream slope ratio of the sub-dam is 1:2. There are 48 sub-dams in total. The top elevation of the last sub-dam is 2.5m higher than that of the previous sub-dam. The dry bulk density of the pile is not less than 1.4t / m 3 .

[0131] The following Table 1 is the elevation-capacity correspondence table of the tailings pond.

[0132] Table 1:

[0133]

[0134]

[0135] According to the above Table 1, draw the relationship diagram of elevation-effective storage capacity / total storage capacity. Figure 2 A diagram showing the relationship between elevation and effective storage capacity / total storage capacity of a non-coal mine tailings storage capacity management method according to another embodiment of the present application is shown.

[0136] Table 2 below is the correspondence table between tailings discharge plan and dam rise speed.

[0137] Table 2:

[0138]

[0139]

[0140] It can be seen from Table 2 that the damming speed is faster in the first, second, fourth and fifth years of using the tailings dam. The tailings pond can meet the production requirements of the mine for 22 years.

[0141] On this basis, Figure 3 A schematic diagram of a flow chart showing a method for managing the storage capacity of a non-coal mine tailings reservoir proposed in another embodiment of the present application is shown.
