Description

Technical Field

[0001] The present invention relates to the technical field of curtain data management, in particular to a parameter storage and management system for curtains. Background Art

[0002] Coal, as my country's primary energy source, remains a constant. Coal mining technology is entering the intelligent mining 4.0 era, characterized by transparency, precision, intelligence, greenness, and safety. Coal mine water hazards, one of the five major associated hazards, have become a serious constraint on the sustainable development of the coal industry, causing significant economic losses and casualties. To address the unique water hazards of the five coal mines, direct regional drainage is recommended. Aohui (Aohui) will provide a significant and stable supply to the five coal mines, but this approach is difficult and costly. Localized drainage, however, is difficult to implement, unreliable, and poses significant safety risks. Neither drainage nor drainage can completely address the water hazards of the five coal mines, and will significantly damage water resources and the ecological environment. After repeated research and demonstration, a comprehensive approach to green mining, characterized by curtain interception, has been developed to address water hazards while simultaneously conserving water and achieving green mining.

[0021] To facilitate understanding by those skilled in the art, the present invention is further described below with reference to the accompanying drawings.

[0022] Figure 1 It is a principle block diagram of the present invention;

[0023] Figure 2 It is a schematic diagram of a broken line graph of the present invention;

[0024] Figure 3 This is a schematic diagram of the visit line setting of the present invention. DETAILED DESCRIPTION

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall 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 the mine curtain conditions, which includes the type, curtain name, curtain data, construction method, form, curtain location and purpose; the 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, designed permissible 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 a 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 "Specifications for Grouting Curtains in Mines" (DZ / T 0285-2015), the permeability of the curtain body during the water pressure test should be ≤ 1.0Lu. The corresponding permeability coefficient index can be calculated using the Babushkin formula: Where: K is the permeability coefficient, m / d; Q is the water pressure flow rate, L / min; L is the water pressure section length, unit is m; S is the total pressure applied during the water pressure test, unit is m; r is the borehole radius, unit is 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 affected by coal mining. While avoiding the waste of resources caused by the covering of coal resources, it also avoids the instability of the curtain caused by the impact of mining during coal mining. Its specific location can be calculated and delineated based on the relevant formulas of trigonometric functions. The specific formulas include:

[0033]

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

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

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

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

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

[0039] (3) Determination of curtain height

[0040] Regarding the selection of the curtain profile location for deeply buried, extremely thick, and highly pressurized aquifers, according to the aforementioned location selection principle of "separation at the top and bottom", a floor-standing curtain must be constructed to completely cover the water passage on the profile, and the top and bottom must be built in a stable relative aquiclude. Theoretically, the curtain only needs to have its upper and lower edges in contact with the bedrock surface of the aquiclude in the vertical direction. However, since the slurry migrates in the direction of least resistance under grouting pressure, it cannot be flush with the top edge like an underground continuous wall. Instead, it can only connect vertically with the top of the bottom plate aquiclude before it can 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 aquiclude.

[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 water flow 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] Assuming that the top and bottom of the curtain are completely watertight and there is no bypass flow, and a small amount of water seepage only exists in the curtain, the effective width of the curtain design can be calculated using Darcy's law formula, 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 inside the curtain, m;

[0045] 2. Water inrush coefficient method

[0046] After the curtain is built in the study area, it can be regarded as an impermeable 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 water head value supported by the curtain, MPa; and Ts is the critical water inrush coefficient, MPa / m.

[0047] 3. Theoretical formula method

[0048] The curtain width is calculated based on the hydrostatic pressure in the direction of the curtain blocking water. 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 stone strength, MPa; K is the safety factor, generally 2 to 5;

[0049] Identifying and classifying the mine curtain condition information and curtain parameters into encrypted data types and non-encrypted data types, marking the mine curtain condition information and curtain parameters belonging to the encrypted data type as first data and sending the data to the encryption processing unit, the encryption processing unit encrypting the received first data, marking the encrypted first data as first encrypted information, and sending 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 moment and the current moment 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 visit moments are sorted in chronological order, and the time difference between two adjacent visit moments is calculated to obtain the inter-visit duration. At the same time, the middle time between the two adjacent visit moments 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, ...; construct a line graph of inter-visit duration and inter-visit time, substitute all inter-visit durations and corresponding inter-visit times 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 visit duration in the line graph according to the visit time, such as Figure 2 T1, T2, T3, T4, T5... in it; connect two adjacent time points to obtain 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 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 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 1, and sum up all the second time height differences to obtain the time height total value 2;

[0058] Finally, mark the first slope mean, second slope mean, time height total value 1 and time height total value 2 as XL1, XL2, SG1 and SG2 respectively; substitute 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; fs1 and fs2 are the weight coefficient ratios 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 length of the circle line is equal to the value of the access right value, select the midpoint of the circle line, draw a straight line perpendicular to the circle line with the midpoint as the starting point, and the length of the straight line is equal to the value of the access ratio, mark the straight line as the access line, connect the end points of the access line to the two circles to obtain two lines, mark the two lines as the first access line and the second access line, wherein the extension lines of the first access line and the second access line pass through the centers of the two circles respectively, calculate the area of ​​the closed figure enclosed by the first access line, the second access line, the circle line and the two circles, extract the value of the area and mark it as the custody value;

[0060] Calculate the difference between the storage duration and the preset duration and mark it as the pre-overtime duration. Extract the value of the pre-overtime duration and mark it as the pre-overtime value. Mark the storage value and the pre-overtime value as CGa and YFa, respectively. 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 data management unit collects and analyzes the storage data of the first encrypted information and the second data to obtain an access ratio, combines the total number of accesses, the total number of uses, and the access right value to obtain a storage value, and obtains a management value based on the storage value and the pre-timeout period. When the management value is less than a set management threshold 1 and greater than a management threshold 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 2, the decrypted first encrypted information is deleted, thereby intelligently managing the storage of parameters.

[0063] The data access unit is used for users 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 corresponding administrator's smart terminal, and the administrator receives a request reply information fed back through the smart terminal, wherein the request reply information includes access prohibited, access allowed, allowed duration, and allowed use;

[0065] Processing the request reply information: when the request reply information indicates that access is prohibited, generating a prohibited access prompt tag and sending it to the user, and at the same time, the total number of prohibitions for the first encrypted information is increased by one; when the request reply information indicates that access is allowed and the allowed time is allowed, decrypting the first encrypted information so that the first encrypted information is converted into the first data and is accessible to the user within the allowed time; if the access permission to the first data is exceeded, the access permission to the first data is disconnected; when the request reply information indicates that access is allowed and the allowed time is allowed and the use is allowed, decrypting 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 allowed time, and at the same time, the total number of uses of the first encrypted information is increased 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 usage times, and total prohibition times of the first encrypted information; sum all allowed durations to obtain the allowed total duration; extract the values ​​of the allowed total duration, total usage times, and total prohibition times and mark them as AE1, AE2, and AE3, respectively;

[0068] The access right value FQ of the first encrypted information is obtained 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 makes it easier for management personnel to clearly understand and process them, and performing access right value analysis on the encrypted curtain parameters. The longer the accumulated time allowed by the management personnel to view, the smaller the corresponding access right value, and thus the smaller the management value. 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.
