[0038] In the present embodiment, a method for predicting water quality of a mine water-filled aquifer running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0039] Figure 2 is a flowchart of a method for predicting water quality of a mine water-filled aquifer according to an embodiment of the present application. As Figure 2 shown, the method includes the following steps:

[0040] Step S201, in the process of coal mining in the first mine, obtaining first data, second data and first order;

[0041] The first data includes the first characteristic parameters of the water of the first water-filled aquifer, and the first characteristic parameters include the concentration of various mineral ions, the TDS value of the water, the PH value of the water, the conductivity of the water, and the ORP value of the water. The second data includes the second characteristic parameters of the rock of each first water-filled aquifer, and the second characteristic parameters include the content of various minerals. The first order is the distribution order of each first water-filled aquifer in the vertical direction. The first water-filled aquifer is the water-filled aquifer of the first mine.

[0042] Step S202, inputting the first data, the second data and the first order into a water-rock reaction kinetics model to obtain at least third data;

[0043] The third data is the first characteristic parameters of the water of all the first water-filled aquifers when the water quality of all the first water-filled aquifers reaches equilibrium. The water-rock reaction kinetics model is used to determine the first characteristic parameters of the water of all the water-filled aquifers after the water of different water-filled aquifers reacts and / or the water of the water-filled aquifer reacts with the rock of the water-filled aquifer according to the distribution order of the water-filled aquifer.

[0044] Through the above embodiment, in the process of coal mining in the first mine, the first characteristic parameters of the water of the water-filled aquifer of the first mine, the second characteristic parameters of the rock of the water-filled aquifer of the first mine, and the distribution order of the water-filled aquifer are input into the water-rock reaction kinetics model to obtain the first characteristic parameters of the water of the water-filled aquifer of the first mine when the water quality of all the water-filled aquifers of the first mine reaches equilibrium. The change of the water quality of the water-filled aquifer of the mine is determined. Since the water-rock reaction kinetics model considers the influence of the reaction of the water of different water-filled aquifers and the reaction of the water of the water-filled aquifer and the rock on the water quality of the water-filled aquifer, the water-rock reaction kinetics model has high accuracy in predicting the water quality of the water-filled aquifer. The existing mine water quality prediction method only considers the influence of the mixture of the water of different water-filled aquifers of the mine on the water quality of the mine, which leads to low accuracy of the predicted water quality of the mine after the water quality of the mine reaches equilibrium.

[0045] In an optional embodiment, the step S201 can be implemented as:

[0046] Obtaining the saturation index of each mineral in the water of the first water-filled aquifer;

[0047] Specifically, the minerals include plagioclase (Na[AlSi3O8]-Ca[Al2Si2O8]), calcite (CaCO3), dolomite (CaMg(CO3)2), and so on. 3)2 The saturation index of the mineral is obtained according to the formula , wherein IAP is the ion activity product of the ion related to the mineral in the first water-saturated aquifer, K is the dissolution reaction equilibrium constant of the mineral, for example, the mineral in the first water-saturated aquifer is calcite (CaCO3), and the ion related to the mineral in the first water-saturated aquifer is Ca + and CO3 2- .

[0048] In a case where the saturation index of at least one of the minerals in the water of the first water-saturated aquifer does not satisfy the preset condition, it is determined that the water quality of the first water-saturated aquifer does not reach equilibrium, and in a case where the saturation index of all the minerals in the water of the first water-saturated aquifer satisfies the preset condition, it is determined that the water quality of the first water-saturated aquifer reaches equilibrium, the preset condition being that the saturation index of the mineral is greater than a preset saturation index.

[0049] In a case where the water quality of at least one of the first water-saturated aquifers does not reach equilibrium, the first data, the second data, and the first sequence are obtained.

[0050] Specifically, the preset saturation index is 0, if the saturation index of all the minerals in the first water-saturated aquifer is greater than the preset saturation index, it is determined that the minerals will not be dissolved again, the water quality of the first water-saturated aquifer reaches equilibrium, the saturation index of at least one of the minerals in the first water-saturated aquifer is less than or equal to the preset saturation index, it is determined that the minerals will be dissolved again, the water quality of the first water-saturated aquifer does not reach equilibrium, in a case where the water quality of at least one of the first water-saturated aquifers does not reach equilibrium, it is determined that the water quality of the first water-saturated aquifer of the first mine will change, it is necessary to re-predict the water quality of all the first water-saturated aquifers after the water quality of all the first water-saturated aquifers reaches equilibrium, in a case where the water quality of all the first water-saturated aquifers reaches equilibrium, it is determined that the water quality of the first water-saturated aquifer of the first mine will not change, and it is not necessary to re-predict the water quality of all the first water-saturated aquifers.

[0051] In an optional embodiment, before the step S201, the method further includes:

[0052] Step S301, constructing the water-rock reaction kinetics model.

[0053] In an optional embodiment, the step S301 can be implemented as:

[0054] In the case that the water quality of at least one second water-filled aquifer does not reach equilibrium, fourth data, fifth data and a second sequence are obtained, the second water-filled aquifer is a water-filled aquifer of the second mine, the fourth data includes the first characteristic parameters of the water of all the second water-filled aquifers, the fifth data includes the second characteristic parameters of the rock of all the second water-filled aquifers, and the second sequence is a distribution sequence of the second water-filled aquifers in the vertical direction;

[0055] Sixth data is obtained, and the sixth data includes the first characteristic parameters of a plurality of first mixed waters at a plurality of continuous time nodes, one of the first mixed waters is obtained by reacting water of any two of the second water-filled aquifers;

[0056] Specifically, in the vertical direction (from high to low), the distribution sequence of the water-filled aquifers of the second mine is Zhidan group aquifer 20-7, lower Anqi group-upper Yanan group aquifer 20-10, lower Anqi group-upper Yanan group aquifer 22-13, middle Yanan group aquifer 22-10, middle Yanan group aquifer 18-13, lower Yanan group aquifer 18-7 and lower Yanan group aquifer 22-7, and the mixing ratio of water of two second water-filled aquifers can be 1:1, 1:2 and 1:3. In the case that the mixing ratio of Zhidan group aquifer 20-7 and lower Anqi group-upper Yanan group aquifer 22-13 is 1:1, the first characteristic parameters (K+, F-, NO2-, PH value, NO3-, ORP value, Ca2+, Mg2+, Cl-, Na+, SO4 2- , conductivity, TDS value) of water of Zhidan group aquifer 20 before mixing, the first characteristic parameters of water of lower Anqi group-upper Yanan group aquifer 22-13, and the first characteristic parameters of the first mixed water after mixing are shown in Table 1. Figure 3 In the case that the mixing ratio of Zhidan group aquifer 20-7 and lower Anqi group-upper Yanan group aquifer 22-13 is 1:2, the first characteristic parameters (K + , F - , Ca 2+ , NO3 - , PH value, CO3 2- , Mg 2+ , HCO3 2- , ORP value, Cl - , Na + , SO4 2- , conductivity, TDS value) of water of Zhidan group aquifer 20 before mixing, the first characteristic parameters of water of lower Anqi group-upper Yanan group aquifer 22-13, and the first characteristic parameters of the first mixed water after mixing are shown in Table 2. Figure 4

[0057] ​Obtaining seventh data, the seventh data comprising the first characteristic parameters of a plurality of second mixed water at a plurality of continuous time nodes, one second mixed water being obtained by reacting water in a second water-filled aquifer with one type of rock;

[0058] Specifically, the first characteristic parameters (Na + , K + , Ca 2+ , Mg 2+ , PH, CI - , SO4 2- , CO3 2- , conductivity, TDS) of the second mixed water obtained by reacting the water in the middle aquifer 18-13 of the Yan'an Formation with the fine-grained sandstone of the Zhidan Group vary from day 0 to day 15 as shown in FIGS. 1 and 2. Figure 5 and 6 .

[0059] Obtaining eighth data, the eighth data comprising the first characteristic parameters of a plurality of third mixed water at a plurality of continuous time nodes, one third mixed water being obtained by sequentially reacting water in a second water-filled aquifer with a plurality of types of rock;

[0060] Based on the fourth data, the fifth data, the sixth data, the seventh data, the eighth data and the second sequence, a water-rock reaction kinetics model is constructed by using a reaction kinetics equation, which can be any one of a pseudo-first-order reaction kinetics equation, an Elovich equation, a parabolic diffusion equation and a pseudo-second-order kinetics equation.

[0061] Specifically, the pseudo-first-order reaction kinetics equation is mainly used to describe a diffusion mechanism controlled kinetics process, which can quantify the speed of reaching equilibrium and the concentration of the solution after equilibrium, and the pseudo-first-order reaction kinetics equation is as follows: M t = M0×[1-exp(-k m ×t)], the Elovich equation is an empirical equation describing a series of reaction mechanisms, such as diffusion of solutes in liquid phase or at interfaces, surface activation and deactivation, etc., and the Elovich equation is as follows: M t = M0+k m ×lnt, the parabolic diffusion equation is used to describe the adsorption and desorption kinetics of mineral ions, and the speed of substance transfer and physicochemical reaction in the release process is determined, and when the reaction is mainly controlled by a diffusion form, the parabolic equation can describe the whole process, in which the parabolic diffusion equation is most suitable for describing the diffusion process of substances in the interior of particles, and the parabolic diffusion equation is as follows: The pseudo-second order kinetics equation is used for the process reaction reaching equilibrium, and the pseudo-second order kinetics equation is as follows: wherein, M t is the cumulative release amount, M0 is the potential release amount, k m is the first-order release rate constant, and t is the reaction time.

[0062] In an optional implementation, the step S202 can be implemented as:

[0063] The first data, the second data, and the first sequence are input into the water-rock reaction kinetics model, and ninth data is obtained, and the ninth data includes a variation range of the first characteristic parameter of the water of the first water-filled aquifer.

[0064] Specifically, the existing mine water quality prediction method can only determine the water quality of the water-filled aquifer after reaching equilibrium, and cannot determine the variation of the water quality of the water-filled aquifer before reaching equilibrium. The water-rock reaction kinetics model can determine the variation of the water quality of the water-filled aquifer before reaching equilibrium, and determine the variation range of the first characteristic parameter of the water-filled aquifer.

[0065] In an optional implementation, after the step S202, the method further includes:

[0066] Step S401, determining a transfer amount of each mineral of the rock of each first water-filled aquifer, and the transfer amount is a content of the mineral of the rock of the first water-filled aquifer dissolved into water;

[0067] Step S402, in a case where the transfer amount of each mineral of the rock of each first water-filled aquifer is less than or equal to the corresponding content, sending the third data to the client.

[0068] Specifically, the content of a mineral of the rock of the water-filled aquifer dissolved into water cannot be greater than the content of the mineral in the rock. If the content of the mineral of the rock of the water-filled aquifer dissolved into water is less than or equal to the content of the corresponding mineral, it indicates that the first characteristic parameter of the water-filled aquifer predicted by the water-rock reaction kinetics model is accurate, and the first characteristic parameter of the water-filled aquifer is sent to the client.

[0069] In an optional implementation, after the step S401, the method further includes:

[0070] In a case where the transfer amount of at least one mineral of the rock of each first water-filled aquifer is greater than the corresponding content, alarm information is sent to the client, and the alarm information indicates that the third data is incorrect.

[0071] In an alternative embodiment, the step S402 described above can be implemented as:

[0072] Based on the third data described above, a plurality of mine water quality maps are generated, and each of the mine water quality maps corresponds to a first characteristic parameter of water in the first water-filled aquifer, and each of the mine water quality maps is a spatial distribution map of the first characteristic parameter of water in the first water-filled aquifer.

[0073] The mine water quality maps are sent to the client.

[0074] Specifically, the spatial distribution maps of the first characteristic parameters of water in each water-filled aquifer are generated based on the third data, so that the water quality conditions of each water-filled aquifer are intuitive and visual. As shown in FIG. 8, the mine water quality map of K+ in Zhidan group aquifer 20-7 is shown, and the darker the color of the area, the higher the concentration of K+. As shown in FIG. 9, the mine water quality map of SO42- in Zhidan group aquifer 20-7 is shown, and the darker the color of the area, the higher the concentration of SO42-. Figure 7 Figure 8 2-

[0100] Specifically, the pseudo-first-order reaction kinetic equation is mainly used to describe the kinetic processes controlled by diffusion mechanisms. It can quantify the rate at which the reaction reaches equilibrium and determine the possible concentration of the solution after equilibrium. The pseudo-first-order reaction kinetic equation is as follows: M t =M0×[1-exp(-k m The Elovich equation, an empirical formula, describes a series of reaction mechanisms, such as solute diffusion in the liquid phase or at the interface, surface activation and deactivation, etc. The Elovich equation is as follows: M t =M0+k m The parabolic diffusion equation (×lnt) describes the adsorption and desorption kinetics of mineral ions, controlled by multiple diffusion mechanisms. It measures the rates of mass transfer and physicochemical reactions during release. When the reaction is primarily controlled by a single diffusion mechanism, the parabolic equation can describe the entire process. It is best suited for describing the kinetics of diffusion within particles. The parabolic diffusion equation is as follows: The pseudo-second order kinetics equation is used for a process reaction reaching equilibrium, and the pseudo-second order kinetics equation is as follows: wherein M t is the cumulative release amount, M0 is the potential release amount, k m is a first-order release rate constant, and t is a reaction time.

[0107] Specifically, the amount of a certain mineral of the rock of the water-filled aquifer dissolved into water cannot be greater than the amount of the mineral in the rock. If the amount of the mineral of the rock of the water-filled aquifer dissolved into water is less than or equal to the amount of the corresponding mineral, it indicates that the first characteristic parameter of the water-filled aquifer predicted by the water-rock reaction kinetics model is accurate, and the first characteristic parameter of the water-filled aquifer is sent to the client.

[0110] In an alternative embodiment, the sending unit comprises:

[0111] The generating module is configured to generate a plurality of mine water quality maps based on the third data, wherein each mine water quality map corresponds to a first characteristic parameter of the water in the first water-filled aquifer, and each mine water quality map is a spatial distribution map of the first characteristic parameter of the water in the first water-filled aquifer.

[0112] The sending module is configured to send the mine water quality maps to the client.

[0113] Specifically, the spatial distribution maps of the first characteristic parameters of the water in each water-filled aquifer are generated based on the third data, so that the water quality conditions of each water-filled aquifer are intuitive and visual, and the mine water quality map of K+ in Zhidan group aquifer 20-7 is as shown in FIG. 6, wherein the darker the color of the area, the higher the concentration of K+. Figure 7 The mine water quality map of SO42- in Zhidan group aquifer 20-7 is as shown in FIG. 7, wherein the darker the color of the area, the higher the concentration of SO42-. Figure 8
