[0072] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0073] The technical solution of this application will be described below through specific embodiments.

[0074] Reference Figure 1 The diagram illustrates a method for generating a filling material proportioning scheme according to an embodiment of this application, which may specifically include the following steps:

[0075] S101. Determine the type of tailings to be used as backfill material.

[0076] This method can be applied to computer devices; that is, the executing entity in this application embodiment can be a computer device, which can be any device with data processing capabilities. For example, the computer device can be a mobile phone, tablet computer, desktop computer, or cloud server, etc. This application embodiment does not limit the specific type of computer device.

[0077] In the embodiments of this application, the backfill material may include at least tailings. When generating the formulation of the backfill material, the type of tailings to be used as the backfill material can be determined first. For example, different types of tailings may include graded tailings, rod mill tailings, and fine-grained tailings, etc.

[0078] S102. Based on the type of tailings, determine multiple proportioning schemes, each of which has a corresponding ash-sand ratio and related parameters.

[0079] In this embodiment, based on the type of tailings, multiple mix design schemes can be determined first. These schemes can be roughly formulated. Each mix design should have a corresponding cement-sand ratio and associated parameters. The cement-sand ratio can refer to the ratio of tailings to cement. For example, for graded tailings, four gradient cement-sand ratios of 1:4, 1:6, 1:8, and 1:10 can be designed, forming four mix design schemes. In these mix design schemes, the associated parameters may include the concentration of the filling slurry, the amount of water, etc.

[0080] In one possible implementation of the embodiments of this application, such as Figure 2 As shown, determining multiple proportioning schemes based on the type of tailings in S102 may specifically include the following steps S1021-S1024:

[0081] S1021. Based on the type of tailings, generate multiple schemes with different ash-sand ratios.

[0082] S1022. Calculate the cost of each of the above schemes.

[0083] In the embodiments of this application, based on the type of tailings that can be used as backfill material, multiple schemes with different ash-sand ratios can be generated first. For example, for graded tailings, four gradient ash-sand ratios of 1:4, 1:6, 1:8, and 1:10 can be designed to form four schemes; for tailings that are a mixture of graded tailings and fine-grained tailings, two gradient ash-sand ratios of 1:6 and 1:10 can be designed to form two schemes.

[0084] For several roughly formulated plans, the cost required to apply the plan for filling operations can be calculated based on the plan's content.

[0085] In one possible implementation of the embodiments of this application, such as Figure 3 As shown, calculating the cost of each option in S1022 may specifically include the following steps S1221-S1223:

[0086] S1221. For any of the above schemes, determine the amount of cement and sand required per unit volume of open space according to the cement-sand ratio.

[0087] In this embodiment, a unit volume void can refer to a void with a fixed numerical volume. For example, the size of the unit volume can be 1 cubic meter. For several roughly formed schemes, the amount of cement and sand required to fill the unit volume void can be determined according to the cement-sand ratio in the scheme, that is, how much mass of tailings and cement needs to be mixed to completely fill the unit volume void.

[0088] S1222, Obtain the volume of the empty space to be filled.

[0089] In this embodiment, the volume of the void to be filled can be obtained by measurement. Typically, before filling the void, its volume needs to be measured. The measured volume can be recorded in the filling operation plan. A computer can obtain the volume of the void to be filled from the operation plan.

[0090] S1223. Calculate the cost of the proposed solution based on the volume of the void to be filled and the amount of cement and sand required per unit volume of void.

[0091] After determining the required amount of cement and aggregate per unit volume of the void and measuring the void's volume, the amount of cement and aggregate needed to fill the entire void can be calculated accordingly. It should be noted that when calculating the amount of cement and aggregate, the required amount of water can also be determined based on the concentration of the filling slurry in the plan.

[0092] After calculating the amount of cement, sand, gravel, and water needed to fill the entire open space, the cost of the corresponding solution can be calculated based on the unit price of each material.

[0093] S1023. Obtain the budget data for the filling operation.

[0094] S1024. Based on the budget data and the cost of each of the schemes, determine a plurality of proportioning schemes from the plurality of schemes.

[0095] In this embodiment, the budget data for filling operations can refer to the planned cost that can be incurred when filling a certain empty space. For multiple roughly formed schemes, the computer equipment can filter out the proportion schemes that meet the budget data requirements based on the budget data, and delete the schemes that do not meet the above budget data requirements.

[0096] In practice, a budget range can be determined based on the budget data. If the budget data itself is a range number, then that range number can be used directly as the budget range. If the budget data is a numerical value, then the budget range can be determined as a certain percentage of that value. For example, if the budget data is data and the percentage is 15%, then the budget range could be [85% * data, 115% * data].

[0097] Based on the calculated costs of each option, the option whose cost falls within the aforementioned budget range can be identified as the matching option.

[0098] Thus, only a portion of the rough plan remained.

[0099] S103. Obtain historical filling data, and select multiple test formulations from multiple formulation schemes based on the historical filling data.

[0100] In this embodiment, historical filling data can be data from actual filling operations of other open spaces that have already been filled. Computer equipment can retrieve historical filling data for each open space from a database and, based on this data, further filter the mix design obtained in the preceding steps.

[0101] In one possible implementation of the embodiments of this application, such as Figure 4 As shown, in step S103, selecting multiple mixing schemes from multiple mixing schemes based on historical filling data can specifically include the following steps S1031-S1033:

[0102] S1031. Identify target vacant fields from the historical filling data that match the type of vacant field to be filled.

[0103] In the embodiments of this application, the target void can refer to a void that matches the type of void to be filled. For example, the target void can be a void with a volume equivalent to the void to be filled; or, the target void can be a void with geological conditions similar to the void to be filled.

[0104] S1032. Determine the actual mix ratio scheme used in the target open space.

[0105] S1033. Based on the mixing ratio scheme actually used in the target open space, select multiple mixing ratio schemes to be tested, wherein the ash-sand ratio of the mixing ratio scheme to be tested is numerically adjacent to that of the mixing ratio scheme actually used in the target open space.

[0106] The actual mix design used in the target void can refer to the mix design of the filling materials actually used when filling the target void. This mix design should include the type of tailings, the ash-sand ratio, etc. used when filling the target void.

[0107] Based on the actual mixing scheme used in the target open field, computer equipment can further filter the existing mixing schemes to obtain multiple mixing schemes to be tested. These mixing schemes can refer to those used in actual experiments.

[0108] In this embodiment, the ash-sand ratio of the mix design to be tested can be numerically adjacent to the ash-sand ratio of the mix design actually used in the target open space. For example, if the mix design actually used in the target open space is 1:6, numerically adjacent ash-sand ratios can include 1:4 and 1:8, etc. Therefore, the mix design to be tested can include three schemes with ash-sand ratios of 1:4, 1:6, and 1:8.

[0109] In this embodiment of the application, when determining the formulation scheme to be tested, it can also be determined whether additives are used in the actual formulation scheme used in the target open space. If additives are used in the actual formulation scheme used in the target open space, the formulation scheme can be further screened based on the additives used, resulting in multiple formulation schemes to be tested.

[0110] S104. When the strength test results of multiple test formulations are received, the target formulation is determined from the multiple test formulations based on the strength test results.

[0111] In this embodiment of the application, for the multiple selected test mix proportions, a strength test can be conducted on each test mix proportion to determine the actual strength of the filling body formed by applying each test mix proportion, and then the final target mix proportion can be determined based on the strength test results.

[0112] In one possible implementation of this application, the strength test results of each tested formulation may include strength data at multiple ages. For example, for formulation one to be tested, the strength test results may include strength data of the filling material at 3 days, 7 days, 14 days, 21 days, and 28 days.

[0113] like Figure 5 As shown, determining the target mix design from multiple test mix designs based on the strength test results in S104 may specifically include the following steps S1041-S1042:

[0114] S1041. Determine the median value of the strength data of the same age among the multiple test mix schemes.

[0115] S1042. The test mix design where the intensity data for each age period is greater than the median value of the intensity data for the corresponding age period is determined as the target mix design.

[0116] In this embodiment of the application, for the strength test results of each mix design to be tested, the computer device can determine the median value of the strength data of the same age in each mix design to be tested.

[0117] For example, for the test mix design scheme 1, test mix design 2, test mix design 3, and test mix design 4, the median value of the strength data for each age group can be calculated for the strength data of each filling body at 3 days, 7 days, 14 days, 21 days, and 28 days, respectively. That is, the median value of the strength data of the above four schemes at 3 days, 7 days, 14 days, 21 days, and 28 days.

[0118] Then, the scheme in which the strength data at each age is greater than the median value of the strength data at the corresponding age is determined as the target mix design. For example, if the strength of the infill at 3 days of age for the tested mix design three is greater than the median strength data of the four schemes at 3 days of age, at 7 days of age, at 14 days of age, at 21 days of age, and at 28 days of age, then the tested mix design three can be designated as the target mix design. The target mix design is the mix design that can be used during the actual filling operation of the unfilled area.

[0119] In this embodiment, the computer device determines the type of tailings used as backfill material and can determine multiple mix proportions based on the tailings type. These multiple mix proportions can be roughly determined based on the tailings type, and each mix proportion can have a corresponding ash-sand ratio and related parameters. Then, the computer device can acquire historical backfilling data and, based on this data, filter out multiple mix proportions to be tested from the multiple mix proportions, completing the first screening of the mix proportions. The selected multiple mix proportions to be tested can be used for actual testing to obtain the strength test results for each mix proportion. Based on the strength test results, the computer device can determine the target mix proportion from the multiple mix proportions to be tested, which is the mix proportion that can ultimately be used for the actual backfilling operation of the void to be filled. This embodiment can quickly screen mix proportions based on the backfill material and the actual conditions of the void to be filled, combined with historical backfilling data, to find the most suitable mix proportion for the current void to be filled.

[0120] It should be noted that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0133] Obtain the volume of the empty space to be filled;
