Referring to fig. 1, fig. 1 shows a flowchart of an implementation of a method for determining a mine cooling system according to an embodiment of the present application, where the method includes the following steps:

and S101, respectively collecting the environmental index information of the mine.

In an embodiment, the environmental index information of the mine includes, but is not limited to, geological geothermal conditions of the mine, atmospheric environment, types of mine heat sources, and other environmental indexes. The environment index information may be information obtained by performing field investigation and analysis on each environment index by a worker. The environment index information may be uploaded to the terminal device by the staff, which is not limited thereto.

S102, determining system index information of various cooling systems to be deployed, wherein the system index information at least comprises technical index information and economic index information.

In an embodiment, the various cooling systems to be deployed include a water-cooling system, an air-cooling system, and an ice-cooling system, which are not limited herein. Wherein, the structure and the cooling principle of each cooling system are different. Therefore, the cooling capacity and the manufacturing cost of each cooling system are different. Based on this, for various cooling systems to be deployed, the index information of each system of the cooling system can be input by the staff.

In an embodiment, the technical index information may be index information, such as a time for cooling the temperature in the mine to a target temperature when the cooling system operates, or system stability of the cooling system, and is not limited thereto. The economic index information may be index information of equipment cost, operation cost, installation cost, and the like of the cooling system, which is not limited. It should be noted that the above-mentioned system index information is only "one or more but not all examples", and in the present embodiment, the various kinds of index information that affect the overall evaluation value of the cooling system are not limited.

S103, establishing scheme evaluation index matrixes of the various cooling systems according to the environment index information and the system index information.

In an embodiment, the scheme evaluation index matrix may be used to perform matrix operation processing according to the environment index information and the system index information of each cooling system, so as to obtain a comprehensive evaluation value of each cooling system. Specifically, if n cooling systems to be deployed are provided, and the number of the environment index information and the number of the system index information are m, the configuration of the index information of each cooling system may be F_i＝{f₁，f₂，…，f _m}. Fi refers to index information composition of the ith cooling system, and i is less than or equal to n; fm is index information belonging to the m-th class in the i-th cooling system. Based on this, the above scheme evaluation index matrix may specifically be:

and the fmn mark is the mth index information in the nth cooling system.

And S104, respectively calculating the comprehensive evaluation values of the various cooling systems based on the scheme evaluation index matrix.

In an embodiment, the comprehensive evaluation value is obtained by calculating, by the terminal device, a value corresponding to each index information of the cooling system, and the comprehensive evaluation value can be considered as an analysis result combining various index information having an influence when the cooling system is deployed in a mine.

In an embodiment, after the scheme evaluation index matrix is established, normalization processing may be performed on each index information in the matrix, and dimensions of a numerical value corresponding to each index information in each cooling system in the matrix are unified. And then, calculating according to the numerical values to obtain an index evaluation value corresponding to each index information in each cooling system. And finally, weighting and summing the index evaluation values and preset weighted values to obtain a comprehensive evaluation value in each cooling system.

And S105, determining the cooling system corresponding to the maximum value of the comprehensive evaluation value as a target cooling system deployed in the mine.

In one embodiment, after the comprehensive evaluation value of each cooling system is calculated in step S104, the cooling system corresponding to the maximum value of the comprehensive evaluation values may be determined as the target cooling system. It can be understood that, for a target cooling system, it is the result of processing the environmental index information and the system index information of various cooling systems. That is, the target cooling system can cool the interior of the mine, and is a system more suitable for cooling the mine (the target cooling system has low cost or the target cooling system has better systematicness).

In this embodiment, after collecting the actual environmental index information inside the mine and the technical index information and the economic index information of each cooling system, a scheme evaluation index matrix capable of making a decision based on multiple index information is constructed to calculate the comprehensive evaluation value of each cooling system. And finally, determining the cooling system corresponding to the maximum value of the comprehensive evaluation value as a target cooling system. So that the finally determined target cooling system achieves reasonable balance between benefit and cost, and the optimal cooling system is ensured to be deployed in the mine.

In an embodiment, referring to fig. 2, in the step S101 of respectively collecting the environmental index information of the mine, the following sub-steps S1011 to S1014 are specifically included, which are detailed as follows:

s1011, determining a plurality of heat release factors in the mine.

In one embodiment, factors affecting heat release in the well include, but are not limited to: the method comprises the following steps of surrounding rock heat release, underground equipment heat release, air self-compression, ore breaking rock heat release, ore heat release and personnel heat release, and is not limited.

And S1012, calculating the total heat release quantity of the heat release factors in a preset time period based on the earth temperature rule of the area where the mine is located.

In one embodiment, the exothermic factors for the surrounding rock heat release, the mining rock heat release, the ore heat release, and the like are generally related to the ground temperature of the mining area. Therefore, when calculating the above-described heat release amount, calculation should be performed based on the ground temperature law.

For example, the above ground temperature law may be: according to the monitoring result of the temperature of the deep tunnel, the temperature of the working face of the same middle section is approximately equal under the condition that the air current passes through, and the difference value is approximately 0.5-1.2 ℃; the difference between the temperature of the rock mass and the temperature of the roadway working surface is large and is about 5-10 ℃. And the air temperature exceeds 30 ℃ below the depth of-600 m, the temperature of part of the area reaches 33 ℃, and the rock temperature of-750 m reaches 41-43 ℃. The observation results in different seasons are different, the temperature difference between summer and winter observation at the same point is about 2 ℃, the rock temperature is relatively wet, and the underground water permeates into the region, so that the temperature is relatively low.

In one embodiment, the total heat release amount of each heat release factor in the preset time period can be calculated by an existing calculation formula. For example, the exotherm for the surrounding rock exotherm may be: q₁＝K_tUL(t_n-t_f) T; wherein, K_tIs the unstable heat exchange coefficient of the roadway rock and the wind current, U is the perimeter of the roadway, L is the length of the roadway, t_nFor the original temperature t of the surrounding rock of the deep roadway_fThe average temperature of the air inlet and outlet of the working face is T, and T is a preset time period. The formula for calculating the heat release amount for each heat release factor is different from each other, and will not be described in detail.

It is added that the above-mentioned heat release factors also include the heat release of the staff, wherein the factors depend on the work load and the work duration of the staff. Wherein, the energy metabolism heat production of general staff is shown in the following table:

TABLE 1 Heat release for workers in different working states

Working state	Rest for taking a rest	Mild physical labor	Moderate physical labor	Heavy physical labor
					Heat release amount	80～115W	200W	275W	470W

Specifically, under the heavy physical labor condition, the calculation formula of the heat release amount of the worker may be: q_R470 nT; wherein Q is_RThe heat release amount of the staff is shown, n is the number of the staff, and T is the average working time of the n staff.

And S1013, calculating the cooled amount of the mine in the preset time period based on the temperature requirement of the mine.

In one embodiment, the temperature requirements of the mine are specified with reference to the requirements of the relevant safety regulations, which will not be described in detail. For example, the air temperature in the mine working area should not exceed 28 ℃, and therefore, the general design cooling standard is as follows: temperature: 28 ℃, humidity: 85 percent. Wherein, the calculation formula of the cooled amount of the mine in the preset time period can be Q_Z＝G*(i₁-i₂) (ii) a Wherein G is the mass air volume of the operation area, i₁For the enthalpy of the air before cooling, i₂The enthalpy value of the cooled air is shown.

In one embodiment, the enthalpy of the air is the total heat contained in the air, which can be determined based on an existing psychrometric chart of the air. Specifically, referring to fig. 3, the vertical axis is temperature, the horizontal axis is air moisture content, and the curve is corresponding air enthalpy. The humidity and the temperature in the air enthalpy value before cooling can be acquired respectively according to the temperature measuring instrument and the humidity measuring instrument, and then the corresponding air enthalpy value is determined. The enthalpy value of the cooled air can be determined according to a cooling standard designed in advance by workers.

And S1014, determining the environmental index information according to the total heat release amount and the cooled amount.

In an embodiment, the total heat release amount is calculated by the staff according to the actual working condition. The cooled quantity is heat which is required to be cooled when the cooling system works after the cooling system is installed in a mine. Based on this, after the total heat release amount and the amount to be cooled are determined, the maximum value of the total heat release amount and the amount to be cooled can be determined as the environmental index information. That is, when the terminal device needs to reduce the ambient temperature inside the mine to the temperature requirement, the maximum value should be taken as the heat (environmental index information) that the cooling system actually needs to cool, so that the target cooling system deployed later can meet the requirement of cooling the inside of the mine.

In an embodiment, referring to fig. 4, in S1013, based on the temperature requirement of the mine, the step of calculating the cooled amount of the mine in the preset time period specifically includes the following substeps S10131-10133, which are detailed as follows:

s10131, acquiring an air enthalpy value of heat contained in the mine before cooling; wherein the enthalpy value of the air is the total heat contained in the air.

S10132, determining the air enthalpy value of the mine after cooling based on the temperature requirement.

S10133, calculating the cooled amount of the mine in the preset time period according to the air enthalpy value before cooling and the air enthalpy value after cooling.

In an embodiment, the above-mentioned manner of acquiring the enthalpy value of the air and the manner of calculating the temperature-decreased amount are explained in the above-mentioned S1013, and will not be further described.

In an embodiment, referring to fig. 5, in the step S104 of calculating the comprehensive evaluation values of the plurality of cooling systems based on the scheme evaluation index matrix, the following substeps S1041-1042 are specifically included, which are detailed as follows:

s1041, calculating index evaluation values of the environment index information and the system index information based on the scheme evaluation index matrix for any cooling system; the environment index information and the system index information respectively have corresponding weight values.

S1042, calculating an index evaluation value of the index information to be calculated of the cooling system based on the index information to be calculated and the index information of the same index.

In one embodiment, the environmental index information and the system index information may be classified into cost type index information and benefit type index information. Based on this, when calculating the evaluation value for each type of index information, it is necessary to perform calculation in consideration of the type of the index information.

Specifically, the physical meanings of the index information are different, and the larger the numerical value of some index information is, the better the numerical value is, such as the refrigerating capacity (technical index information); some index information is preferably smaller in value, such as annual running electricity rate (economic index information). Therefore, referring to fig. 6, in order to facilitate the unified calculation, according to the characteristics of each index information, the index evaluation value of each index information can be calculated in the following two cases, specifically as follows:

in the first case: s10421, if the type of the index information to be calculated is a cost type, determining maximum index information from the index information belonging to the same type of index; and taking the ratio of the index information to be calculated to the maximum index information as the index evaluation value of the index information to be calculated.

Specifically, for the refrigeration capacity index information, a specific numerical value regarding the refrigeration capacity index information in each cooling system may be obtained, and then the maximum value among the numerical values is determined as the maximum value index information. For example, the evaluation finger for the above-described schemeAnd a standard matrix F, wherein each column in the matrix is represented as m index information of one cooling system, and each row is represented as one index information of n cooling systems. Based on this, the maximum value in each line may be determined as the maximum value index information max (f) of the corresponding index information. For the jth index information fij to be calculated of the ith cooling system, theWherein max (fj) is the jth maximum index information, and Eij is the index evaluation value of the jth index information to be calculated in the ith cooling system. The index evaluation value is an evaluation value of index information of the benefit type class.

In the second case: s10422, if the category benefit type of the index information to be calculated is, determining minimum index information from the index information belonging to the same index; and taking the ratio of the minimum index information to the index information to be calculated as the index evaluation value of the index information to be calculated.

Specifically, for annual operating electricity rate index information, a specific numerical value regarding the operating electricity rate index information in each cooling system may be acquired, and then a minimum value among the numerical values is determined as minimum value index information. For example, based on the explanation in the above-described first case, the minimum value in each row may be determined as the minimum value index information min (f) of the corresponding index information; for the jth index information fij to be calculated of the ith cooling system, theAt this time, min (fj) is represented as the jth minimum index information, and Eij is the index evaluation value of the jth index information to be calculated in the ith cooling system. The index evaluation value is an evaluation value of index information of the cost type class.

In an embodiment, after calculating the index information of each cooling system to obtain a corresponding index evaluation value, each index evaluation value may be corresponding to a value replacing the original index information. Specifically, the evaluation matrix of the replaced scheme is as follows:

emn denotes the index evaluation value of the mth type index information in the nth cooling system.

In an embodiment, after the F' matrix is obtained, a weight sum process may be performed according to the weight values corresponding to the index information (environment index information and system index information), so as to obtain the comprehensive evaluation value of each cooling system. Thereafter, the maximum value is determined from the respective comprehensive evaluation values. Namely, the cooling system corresponding to the maximum value of the comprehensive evaluation value is determined as the target cooling system.

Specifically, the calculation formula of the comprehensive evaluation value of each cooling system may be:wherein Eij is an index evaluation value of j-th index information to be calculated in the ith cooling system; wj is the weight corresponding to j-th index information;the sum of the products of the m index evaluation values and the corresponding weight values in the ith cooling system is calculated (namely, the comprehensive evaluation value of the ith cooling system). After that, the maximum value is determined from the n comprehensive evaluation values.

In the embodiment, each cooling system is scored by integrating index information of two categories, so that the finally determined target cooling system can be reasonably balanced between benefit and cost, and the target cooling system is more suitable for mines.

In an embodiment, referring to fig. 7, in S1041, the index evaluation values of the environment index information and the system index information are calculated based on the solution evaluation index matrix, and the following sub-steps S10411-S10412 are further included, which are detailed as follows:

and S10411, aiming at the index information to be calculated of any cooling system, respectively obtaining the index information which belongs to the same index as the index information to be calculated in other cooling systems from the scheme evaluation index matrix.

And S10412, calculating an index evaluation value of the index information to be calculated of the cooling system based on the index information to be calculated and the index information of the same index.

In an embodiment, the steps in S1041 and S1042 are described in detail, and will not be explained again.
