[0002] At present, there are many problems to be solved urgently in the use of water resources in the energy industry in the Yellow River Basin. The water resource usage of coal mines, thermal power plants and coal chemical enterprises in the basin is complex. Key energy bases are facing an imbalance between water supply and demand. The amount of mine water discharged is large but it is difficult to effectively treat and utilize it. Coal chemical and coal power enterprises are also suffering from a shortage of water resources. At present, the utilization of mine water is still insufficient, lacking scientific guidance in scheduling. The proportion of unconventional water sources in the water resource usage of the entire basin is still low, lacking unified planning and scheduling. The spatial contradictions between industries are prominent and the in-depth integration is seriously insufficient, resulting in coexistence of water resource waste and unreasonable utilization.

[0065] The following describes the preferred embodiments of this application with reference to the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain this application and are not used to limit this application.

[0066] Figure 1 is a flowchart of a mine water scheduling method in an embodiment of this application. As Figure 1 shown, the method can be implemented as the following steps S101-S104:

[0067] In step S101, obtain the pre-stored objective function of mine water resource scheduling according to preset requirements;

[0068] In step S102, when there are multiple objective functions, determine the efficacy coefficients among the multiple objective functions;

[0069] In step S103, combine the multiple objective functions into one evaluation function according to the efficacy coefficients of the multiple objective functions;

[0070] In step S104, solve the evaluation function according to the preset constraint conditions to obtain the scheduling result of mine water resources that meets the preset requirements.

[0071] First, obtain the pre-stored objective function of mine water resource scheduling according to preset requirements;

[0072] The objective function of mine water resource scheduling is usually set according to specific scheduling requirements and optimization objectives. In this application, multiple preset requirements and corresponding objective functions are set in advance. For example,

[0073] (1) Aiming at minimizing cost: Since in the scheduling of mine water resources, costs are incurred in links such as pumping, purification treatment, and transportation, which can specifically include pumping energy consumption costs, water treatment costs, and maintenance of water conveyance pipelines, etc. Then the objective function of minimizing cost can be expressed as:

[0074]

[0075] Among them, Z1 is the total cost of water conveyance; c0 is the basic cost of conveying unit water volume from water source i; s(i, j, k) represents the conveyance distance of conveying water from water source i to water user j in sub-region k; x(i, j, k) represents the water volume allocated from water source i to water user j in the kth sub-region.

[0076] The corresponding problem of minimizing water conveyance cost is:

[0077]

[0078] (2) Aiming at maximizing water resource utilization efficiency: In order to make full use of mine water resources and reduce waste, the water resource utilization efficiency can be taken as the goal, and the water resource utilization efficiency is defined as the ratio of the effective water consumption to the total water supply. Then the objective function is:

[0079]

[0080] Among them, Z2 is the total utilization rate of mine water; s(i, j, k) represents the transportation distance of water from water source i to water user j in sub-region k; y(j, k) is the effective water utilization coefficient of water user j in the k-th sub-region; x(i, j, k) represents the water volume allocated from water source i to water user j in the k-th sub-region.

[0081] The corresponding problem of maximizing water resource utilization efficiency is as follows:

[0082]

[0083] Since different production departments have different utilization rates for different qualities of water, such as production water for industrial production departments, domestic water for users, irrigation water for greening departments, etc., therefore, corresponding effective water utilization coefficients can be set for different users in advance according to production and living conditions. The specific setting form is not limited in this application.

[0084] (3) Aiming at maximizing the degree of meeting water demand: Ensuring that the demands of each water use point are met is a very important goal. The goal is to minimize the total sum of unmet water volumes at all water use points. Then the objective function can be set as:

[0085]

[0086] Among them, Z3 is the water volume of mine water that is not in demand; d(j, k) is the water demand of water user j in the k-th sub-region; x(i, j, k) represents the water volume allocated from water source i to water user j in the k-th sub-region.

[0087] At this time, the problem of maximizing the satisfaction of water demand is transformed into the problem of minimizing the unmet water demand, that is:

[0088]

[0089] For the water demand of each user, it can be collected through on-site investigations; it can also be obtained by calculating the average value based on the historical water use data of each user; it can also be estimated according to production and living conditions. In this regard, this application does not make any limitations.

[0090] (4) Aiming at minimizing environmental impact: Since mine drainage may cause certain impacts on the surrounding environment, such as water quality pollution, etc. The objective function can be set as:

[0091]

[0092] Among them, Z3 is the comprehensive environmental pollution value of mine water; e(i, k) is the pollution coefficient when water source i transports water to the k-th sub-region; x(i, j, k) represents the water volume allocated from water source i to water user j in the k-th sub-region.

[0093] The corresponding problem of minimizing environmental impact is as follows:

[0094]

[0095] In this application, when determining the objective function, the maximum comprehensive utilization benefit of the available water resources within the base is taken as the goal. This comprehensive benefit is not only the economic benefit, but also includes social and ecological environmental benefits. Therefore, the goal of optimal water resource allocation in this application can be decomposed into three sub-goals: economic benefit, social benefit, and ecological environmental benefit goals.

[0096] (1) Economic benefit goal: Economic benefit refers to the comparison between input and output in economic activities, obtaining the maximum economic output with the least resource input. In this application, the economic benefit of water resource allocation is analyzed by the water resource utilization price, that is, to determine how much cost-saving water use can be achieved by the current water resource allocation. Based on field research, the comprehensive water fee is 10.5 yuan / ton (water resource tax 2 yuan / ton + water fee 8.5 yuan / ton). Therefore, the economic benefit objective function is determined as follows:

[0097]

[0098] Among them, f1 is the economic benefit; gdp(i,j,k) is the p benefit coefficient, representing the benefit that can be generated by the water consumption per unit of industry; coefficient(i,j,k) is the comprehensive weight coefficient of the allocated water volume, representing the priority order of water supply from the water source to each water user in each sub-region; x(i,j,k) represents the water volume allocated from water source i to water user j in sub-region k.

[0099] Since the larger the value corresponding to the economic benefit objective function, the better, the problem of maximizing economic benefit is:

[0100]

[0101] Specifically, the comprehensive weight coefficient coefficient(i,j,k) of the allocated water volume can represent the priority order by assigning different comprehensive weight coefficient values coefficient(i,j,k) to the water supply situations from different water sources to each water user in each sub-region. The specific method is as follows:

[0102] Numerical value representation method: When making water supply allocation decisions, sort each water supply combination from largest to smallest according to the coefficient value. The larger the coefficient value, the higher the priority of water supply execution. Assign a larger coefficient value to the water supply situation with a higher priority level and a smaller coefficient value to the lower priority level. For example, coefficient(i1,j1,k1) = 5 indicates that the water supply from water source i1 to water user k1 in sub-region j1 has a higher priority; while coefficient(i2,j2,k2) = 1 indicates that the water supply from water source i2 to water user k2 in sub-region j2 has a lower priority.

[0103] Normalized representation: First, determine all possible water supply combinations according to the actual situation, and preliminarily evaluate their relative importance for each combination (the expert scoring method or other methods can be used). Then, normalize these importance scores so that all coefficient values are within the range of [0, 1]. For example, after a series of evaluations and calculations, coefficient(i3,j3,k3) = 0.8, coefficient(i4,j4,k4) = 0.3, etc. Although these values are within a relatively small range, the relative magnitude relationship between them can still reflect the priority order. The advantage of this method is that it can intuitively show the proportion of the relative importance of each water supply combination in the whole.

[0104] In an embodiment of the present application, the economic benefit can also consider taking the comprehensive water use value, that is, the potential benefit brought by the mine water scheduling. Specifically, the objective function is as follows:

[0105]

[0106] where F1 is the regional comprehensive water use value, K is the total number of sub-regions, and F a,k 、F b,k 、F c,k are the water use values of water resources in production, life, and ecology respectively. Among them,

[0107]

[0108] J is the total number of water users; x a (i,j,k), x b (i,j,k), x c (i,j,k) are the water consumption of production, life, and ecological water use of the j-th user in the k-th sub-region respectively; v a (j,k), v b (j,k), v c (j,k) are the water use values per unit volume of production, life, and ecological water of the j-th user in the k-th sub-region respectively.

[0109] Among them, the production water use value can be determined by the marginal productivity method, that is, when other production factor inputs remain unchanged, the increase in output brought by increasing one unit of water resource input is the marginal productivity of water resources, and this is used to measure the production value of water resources. The specific calculation formula is as follows:

[0110] v a (j,k) = MP(i,j,k) × P(i,j,k)

[0111] where v a(j,k) is the unilateral production water value of the jth user in the kth sub-area; MP(j,k) is the marginal output of water resources of the jth user in the kth sub-area; P(j,k) is the unit price of the product of the jth user in the kth sub-area.

[0112] The value of domestic water is mainly reflected in meeting the daily needs of residents. It can be calculated using the replacement cost method, for example, by replacing the value of domestic water with a preset proportion:

[0113] v b (j,k)=α×Price(j,k)

[0114] Among them, v a (j, k) is the unit domestic water value of user j in the kth sub-area; α is a preset proportional coefficient, for example, 0.8; Price (j, k) is the unit price of daily water used by user j in the kth sub-area.

[0115] Ecological water value assessment aims to measure the contribution of water resources to maintaining the structure and function of the ecosystem, which can be determined through a questionnaire.

[0116] (2) Social benefit objectives: Social benefit refers to the positive impact of a project, policy or activity on social development, social equity and other aspects. In this application, the aforementioned goal of maximizing the degree of water demand is selected to represent the social benefit objective, that is, social benefit refers to whether the allocation of water resources can meet the water demand of various industries and sectors. In the same way as the above method, the problem of maximizing the water demand is converted into the problem of minimizing the amount of water that is not met. Therefore, the social benefit objective function is determined as follows:

[0117]

[0118] Among them, f2 is the amount of water that is not met; Ws is the social water demand of the entire area; coefficient(i,j,k) is the comprehensive weight coefficient of the allocated water volume, which represents the priority of water supply from water sources to each water user in each sub-district; x(i,j,k) represents the amount of water allocated from water source i to water user j in sub-district k.

[0119] The problem of minimizing the amount of water that does not meet the water demand is:

[0120]

[0121] (3) Ecological and environmental benefit objectives: Ecological and environmental benefits refer to the beneficial effects of human activities on the structure, function and ecological services of the ecosystem. In this application, it is hoped that water resource allocation can meet the water demand of the ecological environment as much as possible. Similar to the social benefit treatment method, this application converts the problem of maximizing ecological and environmental benefits into the problem of minimizing the water demand of the Wei Mazu ecological water use. Therefore, the ecological and environmental benefit objective function is determined as follows:

[0122]

[0123] Among them, f3 is the amount of water that fails to meet the ecological water demand; We is the ecological water demand of the entire region; coefficient(i, j, k) is the comprehensive weight coefficient of the allocated water volume, representing the priority order of water sources supplying water to each water user in each sub-region; x(i, j, k) represents the amount of water allocated by water source i to water user j in sub-region k; m(i, j, k) is the ecological water coefficient of user j in the kth sub-region.

[0124] Then, the minimization problem of the amount of water that fails to meet the ecological water demand is as follows:

[0125]

[0126] Secondly, when there are multiple objective functions, determine the efficacy coefficients of the multiple objective functions. When there are multiple objective functions, determining the efficacy coefficients is an important step in transforming multiple objective functions with different natures into a unified index that can be comprehensively compared. Specifically, classify the multiple objective functions, and determine the correlation between the actual value in the objective function and the efficacy of the objective function; determine whether the multiple objective functions are positive functions or negative functions. When the actual value in the objective function is positively correlated with the efficacy of the objective function, determine that the objective function is a positive efficacy function; when the actual value in the objective function is negatively correlated with the efficacy of the objective function, determine that the objective function is a reverse efficacy function. Then, determine the efficacy coefficient corresponding to the objective function according to the category of the objective function; finally, merge the multiple objective functions into an evaluation function according to the efficacy coefficients corresponding to the objective functions.

[0127] Determine the corresponding efficacy coefficients for each objective function. When the objective function is better the larger it is, such as the water resource utilization efficiency, the formula for calculating the efficacy coefficient is as follows:

[0128]

[0129] When the objective function is better the smaller it is, such as the water resource utilization efficiency, the formula for calculating the efficacy coefficient is as follows:

[0130]

[0131] Of course, the efficacy coefficients can also be determined by other methods, such as piecewise linear efficacy coefficients and curvilinear efficacy coefficients, which are not limited in this application.

[0132] Then, merge the multiple objective functions into an evaluation function according to the efficacy coefficients of the multiple objective functions. After determining the efficacy coefficients, corresponding weights λ can be assigned according to the importance of each objective function. l, where ∑ l λ l = 1. Then, construct a comprehensive evaluation function H(x) to comprehensively measure the degree of achievement of multiple objectives:

[0133] Min H(x) = ∑ l λ l (d l -1) 2 .

[0134] Finally, solve the evaluation function according to the pre-set constraint conditions to obtain the scheduling result of the mine water resources that meets the preset requirements.

[0135] Water resources scheduling is a complex process that requires considering various constraint conditions to ensure the rational allocation and sustainable utilization of water resources. This application considers the constraint conditions from the following aspects:

[0136] (1) Water supply end constraint: The sum of the water volumes allocated from water source i to various users in sub-region k cannot exceed its available water volume.

[0137]

[0138] Among them, i represents the water supply source. For example, i = 1, 2, 3, K can be used to represent surface water, groundwater, mine water, and reclaimed water respectively; j represents the water use department. For example, j = 1, 2,..., J can be used to represent domestic, agricultural, coal, coal power, coal chemical industry, general industry, construction, and the tertiary industry respectively; k represents the calculation sub-region. For example, it can be divided into k = 1, 2,..., K sub-regions according to the system structure characteristics of each coal base; x(i, j, k) represents the water volume allocated from water source i to user j in sub-region k; W(i) represents the maximum available water volume of water source i.

[0139] (2) Water demand end constraint: The water volume allocated to various users cannot be lower than its minimum water demand and cannot exceed its maximum water use capacity.

[0140]

[0141] Among them, W min (i, j, k) represents the lower limit of the water demand of user j in sub-region k; W max (i, j, k) represents the upper limit of the water demand of user j in sub-region k.

[0142] The lower limit of the water demand is the water volume to meet the most basic production and domestic water use, which can be determined through research based on the specific user situation; of course, the upper and lower limits of the water demand can also be determined by multiplying the historical average water use volume by a preset coefficient. For example, the lower limit is taken as 0.7 times the historical average water use volume, and the upper limit is taken as 1.3 times the historical average water use volume.

[0143] (3) Economic constraint: Consider that the water conveyance cost cannot be higher than the price of daily water use.

[0144] [c0 + s(i, j, k)] × x(i, j, k) ≤ Price(j, k);

[0145] Where, Z1 is the total cost of water conveyance; c0 is the basic cost of conveying a unit of water volume from water source i; s(i, j, k) represents the conveyance distance of conveying water from water source i to water user j in sub - area k; x(i, j, k) represents the water volume allocated from water source i to water user j in the k - th sub - area; Price(j, k) is the unit price of daily water use of user j in the k - th sub - area.

[0146] (4) Ecological constraint: Either too high or too low groundwater level will have a negative impact on the surrounding ecological environment. Therefore, determine the maximum and minimum available water volumes of each water source.

[0147]

[0148] Where, Q imin and Q imax respectively represent the maximum available water volume and the minimum available water volume of water source i; x(i, j, k) represents the water volume allocated from water source i to water user j in the k - th sub - area.

[0149] (4) Non - negative constraint: That is, the water supply volume from each water source to each user cannot be negative.

[0150] x(i, j, k) ≥ 0.

[0151] Under the above - mentioned constraint conditions, use the non - linear optimization solution program in Lingo software to solve the evaluation function, and then obtain the optimal solution of the water resources optimal allocation model for the coal base.

[0152] The beneficial effects of this application are as follows: Obtain the pre - stored objective function of mine water resources scheduling according to the preset requirements; when there are multiple objective functions, determine the efficacy coefficients of the multiple objective functions; merge the multiple objective functions into one evaluation function according to the efficacy coefficients of the multiple objective functions; solve the evaluation function according to the preset constraint conditions to obtain the scheduling result of mine water resources that meets the preset requirements. Since the corresponding objective function can be called according to the preset requirements, different scheduling objectives can be determined according to the actual needs to meet the reasonable scheduling of mine water under multiple - demand situations. In addition, since the corresponding objective function can be extracted for different regions, and the objective function can be added according to the demand when there is a need, the flexibility of model application is improved.

[0153] In one embodiment, when the preset requirement is to maximize economic benefits, the objective function in the above - mentioned step S101 is:

[0154]

[0155] Among them, f1 is the potential economic benefit; gdp(i, j, k) is the p benefit coefficient, representing the benefit that can be generated by the water consumption per unit of the industry; coefficient(i, j, k) is the comprehensive weight coefficient of the allocated water volume, representing the priority order of water supply from the water source to each water user in each sub-region; x(i, j, k) represents the water volume allocated from water source i to water user j in sub-region k.

[0156] In one embodiment, when the preset requirement is to maximize the social benefit, the objective function in the above step S101 is:

[0157]

[0158] Among them, f2 is the water volume of the unmet water demand; Ws is the social water demand of the entire region; coefficient(i, j, k) is the comprehensive weight coefficient of the allocated water volume, representing the priority order of water supply from the water source to each water user in each sub-region; x(i, j, k) represents the water volume allocated from water source i to water user j in sub-region k.
