[0025] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1As shown, a parameter storage management system for a curtain is applied to a server, and includes a data acquisition unit, a parameter analysis unit, a parameter storage unit encryption processing unit, a data management unit and a data access unit;

[0027] The data acquisition unit collects information on mine curtain conditions, which includes type, curtain name, curtain data, construction method, form, curtain position and purpose; curtain data includes water pressure flow, water pressure section length, total pressure applied during test water pressure, borehole radius, positions of curtain start and end points, bending deformation zone cutting angle, cracking zone cutting angle, bending deformation zone height, cracking zone height, mining influence zone range, curtain average permeability coefficient, aquifer thickness, design allowable curtain single width infiltration, groundwater level outside the curtain and groundwater level inside the curtain, etc.; the mine curtain condition information is sent to the parameter analysis unit.

[0028] The parameter analysis unit analyzes and processes the curtain data in the mine curtain situation information to obtain curtain parameters; the curtain parameters include permeability coefficient, curtain length, curtain height, and curtain width; specifically:

[0029] The parameter analysis unit determines the curtain's permeability coefficient based on the water pumping (pressure) test on the curtain. By comparing the permeability coefficients before and after the curtain, the curtain's construction quality can be qualitatively evaluated. According to the requirements of the "Mine Curtain Grouting Specification" (DZ / T 0285-2015), the water pressure test inside the curtain body, the water permeability should be ≯1.0Lu According to the Babushkin formula, the corresponding permeability coefficient index can be obtained, and the formula is: Where: K is the permeability coefficient, m / d; Q is the water pressure flow, L / min; L is the water pressure section length, in m; S is the total pressure applied during the water pressure test, in m; r is the borehole radius, in m;

[0030] (1) Curtain position and length, the position of the curtain start and end points: To prevent bypass flow, the two ends of the curtain must be built on the identified stable impermeable boundary, or the erosion and pinch-out boundary of the target aquifer, so that the two ends of the curtain overlap.

[0031] (2) Curtain plane shape and length

[0032] First, the plane layout of the curtain should be limited to the outside of the target aquifer and within the recharge channel of all basal aquifers to the target aquifer. Try to stay away from the strong recharge channel between aquifers to avoid building the curtain under large-scale dynamic water recharge conditions. Secondly, the plane layout of the curtain should be outside the range of influence of coal mining. While avoiding the waste of resources caused by covering coal resources, avoid the instability of the curtain due to the influence of mining during coal mining. Its specific position can be calculated and delineated based on the relevant formulas of trigonometric functions. The specific formulas include:

[0033]

[0034] Where: l, l'-the scope of the mining impact zone, m;

[0035] H-height of cracking zone, m;

[0036] h-bending deformation zone height, m;

[0037] β(β′), γ(γ′)-crack zone cutting angle, °;

[0038] - bending deformation belt cutting angle, °;

[0039] (3) Determination of curtain height

[0040] Regarding the selection of the curtain profile position for deeply buried, extremely thick, and highly pressurized aquifers, according to the position selection principle of "separation at the top and bottom" mentioned above, a floor-standing curtain must be built to completely cover the water passage on the profile, and the top and bottom must be built in a stable relative impermeable layer. Theoretically, the curtain can be vertically contacted with the bedrock surface of the impermeable rock layer at its upper and lower edges, but because the migration direction of the slurry under the grouting pressure is along the direction of minimum resistance, it cannot be flush with the upper edge like an underground continuous wall, but can only be vertically connected to the top of the bottom plate impermeable layer, and then diffuse and migrate horizontally to the surrounding areas. Therefore, the curtain should vertically penetrate 10 to 15 meters below the weathering crust of the bedrock of the top and bottom plate impermeable layers;

[0041] (4) Determination of curtain width: There are many ways to calculate the effective width of the curtain, including analytical method, water inrush coefficient method, theoretical formula method, etc. The analytical method calculates the curtain width based on the amount of water flowing through the curtain. The empirical formula uses the water inrush coefficient to calculate the curtain width based on the water pressure. The theoretical formula introduces the concept of curtain strength and calculates the curtain width based on the water pressure. The in-situ test determines the effective width of the curtain based on the relationship between the interception rate and the curtain thickness. The calculation process of various methods is as follows:

[0042] 1. Analytical method

[0043] Assume that the top and bottom of the curtain are completely watertight and there is no bypass phenomenon; a small amount of seepage only exists in the curtain; use Darcy's law formula to calculate the effective width of the curtain design, which can be evolved into:

[0044] Where L is the effective width of the curtain, m; K m is the average permeability coefficient of the curtain, m / d; M is the thickness of the aquifer, m; Q 单 is the permissible infiltration amount of curtain per width in design, m 2 / d;H 外 is the groundwater level outside the curtain, m; H 内 is the groundwater level in the curtain, m;

[0045] 2. Water inrush coefficient method

[0046] After the curtain in the study area is built, it can be regarded as a water-proof layer, bearing lateral water pressure. By referring to the concept of water inrush coefficient, the effective width of the curtain can be calculated. The calculation formula is: L = P / Ts; where L is the effective width of the curtain, m; P is the actual head value borne by the curtain, MPa; Ts is the critical water inrush coefficient, MPa / m.

[0047] 3. Theoretical formula method

[0048] The curtain width is calculated according to the hydrostatic pressure of the curtain in the water-blocking direction. According to the uniformly distributed "simply supported beam" theory, the calculation formula is: Where L is the effective width of the curtain, m; P is the actual water head value borne by the curtain, MPa; M is the thickness of the aquifer, m; K p is the strength of the stone, MPa; K is the safety factor, generally 2 to 5;

[0049] Identify and classify the mine curtain situation information and curtain parameters into encrypted data types and non-encrypted data types, mark the mine curtain situation information and curtain parameters belonging to the encrypted data type as first data and send them to the encryption processing unit, the encryption processing unit encrypts the received first data, marks the encrypted first data as first encrypted information, and sends the first encrypted information to the parameter analysis unit;

[0050] The parameter analysis unit receives the first encrypted information sent by the encryption processing unit, marks the mine curtain situation information and curtain parameters belonging to the non-encrypted data type as second data; and sends the first encrypted information and the second data to the parameter storage unit.

[0051] The parameter storage unit stores the first encryption information and the second data.

[0052] The data management unit manages the first encrypted information and the second data. The specific management process is as follows:

[0053] Collecting storage data of the first encrypted information and the second data, wherein the storage data includes storage time, storage location, access time, total number of accesses, total number of uses, and access rights;

[0054] Analyze the stored data. The specific analysis steps are as follows:

[0055] See also Figure 2As shown, the time difference between the storage time and the current time is calculated to obtain the storage duration, and the storage duration is compared with the corresponding preset duration. When the storage duration is greater than the preset duration, the total number of visits is analyzed. When the total number of visits is greater than the set number threshold, all the access times are sorted in chronological order, and the time difference between two adjacent access times is calculated to obtain the inter-visit duration. At the same time, the middle time between two adjacent access times is calculated and marked as the inter-visit time of the inter-visit duration, as shown in FIG. Figure 2 t1, t2, t3, t4, t5, ... in the figure; construct a line graph of the inter-visit duration and the inter-visit time, substitute all the inter-visit durations and the corresponding inter-visit time into the line graph, and analyze to obtain the inter-visit ratio. The specific process is as follows:

[0056] First, mark the time points corresponding to the access duration in the line graph according to the access time, such as Figure 2 T1, T2, T3, T4, T5... in it; connect two adjacent time points to get a broken line, mark the straight line between the two adjacent time points as the visiting time line, compare the heights of the two time points, when the height of the previous time point is higher than that of the next time point, mark the visiting time line between the two as the first time line, calculate the slope and time height difference of the first time line and mark them as the first slope and the first time height difference respectively; when the height of the previous time point is lower than that of the next time point, mark the visiting time line between the two as the second time line, calculate the slope and time height difference of the second time line and mark them as the second slope and the second time height difference respectively;

[0057] Secondly, sum up the absolute values ​​of all the first slopes and take the average to obtain the first slope mean, sum up the absolute values ​​of all the second slopes and take the average to obtain the second slope mean; sum up all the first time height differences to obtain the time height total value one, and sum up all the second time height differences to obtain the time height total value two;

[0058] Finally, mark the first slope mean, the second slope mean, the time height total value 1 and the time height total value 2 as XL1, XL2, SG1 and SG2 respectively; substitute them into the preset model The visit-to-visit ratio FJ is obtained, where me1 and me2 are the weight coefficient factors corresponding to the first slope mean and the second slope mean, respectively, and fs1 and fs2 are the weight coefficient proportions corresponding to the total time height value 1 and the total time height value 2, respectively;

[0059] See also Figure 3As shown, the values ​​of the access ratio, the total number of accesses, the total number of uses and the access right value are extracted and processed to obtain the custody value. The specific process is: construct two circles with the values ​​of the total number of accesses and the total number of uses as radii respectively, place the two circles on the same horizontal line, adjust the horizontal spacing between the two circles and connect them horizontally, mark the connecting line as the circle line, wherein the value of the circle line length is equal to the value of the access right value, select the midpoint of the circle line, use the midpoint as the starting point to draw a straight line perpendicular to the circle line, and the length of the straight line is equal to the value of the access ratio, mark the straight line as the visit line, connect the end points of the visit line to the two circles to obtain two lines, mark the two lines as the first visit line and the second visit line, wherein the extension lines of the first visit line and the second visit line pass through the centers of the two circles respectively, calculate the area of ​​the closed figure surrounded by the first visit line, the second visit line, the circle line and the two circles, extract the value of the area and mark it as the custody value;

[0060] Calculate the time difference between the storage time and the preset time and mark it as the pre-overtime time, extract the value of the pre-overtime time and mark it as the pre-overtime value, mark the storage value and the pre-overtime value as CGa and YFa respectively, and set the weight coefficients corresponding to the storage value and the pre-overtime value as eq1 and eq2 respectively;

[0061] Substitute the preset model FP=CGa×eq1-YFa×eq2 to obtain the control value FP. When the control value is less than the set control threshold 1 and greater than the control threshold 2, delete the second data and decrypt and store the first encrypted information. When the control value is less than the control threshold 2, delete the decrypted first encrypted information.

[0062] The storage data of the first encrypted information and the second data are collected and analyzed by the data management unit to obtain the access ratio, the total number of accesses, the total number of uses and the access right value are combined to obtain the storage value, and the management value is obtained based on the storage value and the pre-timeout period. When the management value is less than the set management threshold value 1 and greater than the management threshold value 2, the second data is deleted and the first encrypted information is decrypted and stored. When the management value is less than the management threshold value 2, the decrypted first encrypted information is deleted, thereby intelligently storing and managing the parameters;

[0063] The data access unit is used for the user to access the first encrypted information and the second data and perform access right value analysis. The specific process is as follows:

[0064] When the user clicks to access the corresponding first encrypted information, the administrator corresponding to the first encrypted information is obtained, and a viewing request instruction corresponding to the first encrypted information is generated, the viewing request instruction is sent to the smart terminal of the corresponding administrator, and the request reply information fed back by the administrator through the smart terminal is received, wherein the request reply information includes access prohibited, access allowed, allowed duration, and allowed use;

[0065] Process the request reply information: when the request reply information is access denied, generate an access denied prompt tag and send it to the user, and the total number of times the first encrypted information is denied increases by one; when the request reply information is access allowed and the duration allowed, decrypt the first encrypted information so that the first encrypted information is converted into the first data and is accessible to the user within the permitted duration; the access right to the first data is disconnected when the permitted duration is exceeded; when the request reply information is access allowed, duration allowed, and use allowed, decrypt the first encrypted information so that the first encrypted information is converted into the first data and is accessible and copied by the user within the permitted duration, and the total number of times the first encrypted information is used increases by one;

[0066] Marking the time when the access permission and the permission duration are received as the access time of the first encrypted information, and increasing the total number of access times of the first encrypted information by one;

[0067] Obtain all allowed durations, total number of uses, and total number of prohibitions of the first encrypted information; sum all allowed durations to obtain the allowed total duration; extract the values ​​of the allowed total duration, the total number of uses, and the total number of prohibitions and mark them as AE1, AE2, and AE3, respectively;

[0068] The access right value FQ of the first encrypted information is obtained by using the formula FQ=AE3×ms3+ms2 / AE2+ms1 / AE1; wherein me1, me2 and me3 are all preset weight coefficients; and the access right value of the second data is a fixed preset value.

[0069] When the present invention is in use, the present invention collects the storage data of the first encrypted information and the second data through the data management unit and analyzes them to obtain the access ratio, combines the total number of accesses, the total number of uses and the access right value to obtain the storage value, and obtains its management value based on the storage value and the pre-timeout period. When the management value is less than the set management threshold value one and greater than the management threshold value two, the second data is deleted, and the first encrypted information is decrypted and stored. When the management value is less than the management threshold value two, the decrypted first encrypted information is deleted, thereby reasonably storing and managing the parameters; requesting access to the encrypted stored curtain parameters through the data access unit is convenient for the management personnel to clearly understand and process them, and performing access right value analysis on the encrypted curtain parameters. The longer the cumulative time allowed by the management personnel to view, the smaller the corresponding access right value, thereby making the management value smaller. When it is less than the management threshold value one, it is decrypted and stored, and when it is less than the management threshold value two, it is deleted.
