Description

Technical Field

[0001] The present invention relates to the technical field of resource reserve management, and particularly to a method for managing the geological resource reserves of a mine. Background Art

[0002] In the management of mine geological resource reserves, accurately estimating reserves, monitoring reserve changes, and evaluating the sustainable utilization status of reserves are crucial. However, traditional reserve management methods often rely on manual experience and simple data statistics, lacking systematicness and accuracy. To overcome these limitations, a method for managing mine geological resource reserves based on algorithm formulas is frequently used in the prior art.

[0003] However, some of the existing technologies based on algorithm formulas lack a real-time reserve change monitoring mechanism, unable to timely detect the trends of reserve reduction and increase, affecting the timeliness of management decisions. Moreover, the sustainable utilization status of reserves is ignored in management, lacking systematic evaluation indicators and feedback mechanisms. In addition, the management and presentation methods of historical data are single, lacking intuitive visualization tools, making it difficult for managers to comprehensively understand and grasp the reserve status of the mine. Summary of the Invention

[0004] The purpose of the present invention is to provide a method for managing the geological resource reserves of a mine, which solves the problems raised in the above background art.

[0007] Optionally, the calculation formula of the information unit reflecting the resource reserve status is as follows: Q = KM × HD - YKM × HC; Where: Q is the geological resource reserve; KM is the mining area, and KM reflects the total area that can be mined within the same mine; HD is the average thickness, and HD reflects the average degree of the ore body thickness within the mining area KM; YKM is the area of the mined area, and YKM reflects the total area of the mining area KM that has been mined up to the current time; HC is the average recovery rate, and HC reflects the average situation of the proportion of the actual mined mineral weight to the planned mined mineral weight within the mined area YKM; KM × HD reflects the potential recoverable reserve of the entire mine; YKM × HC reflects the part that cannot be fully recovered due to reasons including mining losses and dilution in the mined area; Based on the situations reflected by KM × HD and YKM × HC, Q calculated by KM × HD - YKM × HC is the net reserve of the current resource reserve obtained by subtracting the part that cannot be fully recovered from the potential recoverable reserve.

[0008] Optionally, the calculation formula of the resource reserve change trend unit is as follows: ; Where: BD is the reserve change rate; Q last is the previous reserve of the geological resource, and Q last reflects the geological resource reserve Q calculated by using the information unit reflecting the resource reserve status after the previous mining of other mining areas in the same mining area KM, and when calculating for the first time, it is set that Q last = Q, then BD = 0; Q - Q last reflects the difference change in the resource reserve after adjacent two times of mining different mining areas in the same mining area KM; reflects the change rate of the difference change accounting for the previous reserve Q of the geological resource last ; If the value of BD is positive, it reflects that Q is higher than Q last, and the greater the difference, the greater BD; If the value of BD is negative, it reflects that Q is lower than Q last , and the greater the difference, the smaller BD; If the value of BD is 0, it reflects that Q is equal to Q last .

[0009] Optionally, the calculation formula for the unit evaluating the sustainable utilization status is as follows: ; Where: KC is the sustainable utilization index of reserves; is to obtain a value between 0 and 1, and take the absolute value of KC plus 1 as the denominator to make the denominator always greater than 0 and avoid the error of dividing by 0. Taking the square root is to compress the value range so that the result is distributed between 0 and 1; is the result value of the proportion of the currently unmined area in the total area. Multiply by to reflect the sustainable utilization situation within the mining area KM under the influence of the reserve change rate BD on the currently unmined area.

[0010] Optionally, the analysis based on the calculation result of the sustainable utilization index KC of reserves is as follows: When the value of BD is negative and the difference between Q and Q last is large, the value of KC will approach 0, indicating that the reserve resources decrease and the sustainable utilization amount decreases; When the value of BD is positive and the difference between Q and Q last is small, the value of KC will approach 1, indicating that the reserve resources increase and the sustainable utilization amount increases; When the value of BD is 0, the value of KC is 0, indicating that the reserve resources are stable and the sustainable utilization amount is stable.

[0011] Optionally, based on the sustainable utilization index KC of reserves, and all the sustainable utilization indexes KC of the same mining area KM obtained each time are collected and managed by the data acquisition module, and the data visualization module is used for the drawing management of the line graph. The specific analysis after management and drawing is as follows: If the sustainable utilization index KC of reserves shows a continuous upward trend on the line graph, it reflects that the mining resources within the current mining area KM are rich; If the sustainable utilization index KC of reserves shows a continuous downward trend on the line graph, it reflects that the mining resources within the current mining area KM tend to be exhausted; If the reserve sustainable utilization index KC shows a continuous and gentle trend on the line graph, it reflects that the exploited resources within the current exploited area KM are abundant.

[0012] Optionally, the equipment used in the geological exploration unit includes geological exploration equipment, and is used for geological exploration and collection, including the exploited area KM and the average thickness HD; The equipment used in the exploitation record unit includes an exploitation record system, and is used for recording the exploited area YKM, the average recovery rate HC, and the results of the geological resource reserve Q, the reserve change rate BD, and the reserve sustainable utilization index KC during each exploitation process; The equipment used in the monitoring sensor unit includes monitoring sensors, and is used for real-time monitoring of the changes in the mine geological resources; The equipment used in the line graph drawing unit and the data visualization processing unit includes data visualization software, and is used for plotting the calculated reserve sustainable utilization index KC values and the historical reserve sustainable utilization index KC into a line graph; The equipment used in the reserve monitoring module includes a computer and a server, and is used for data processing and calculation from the resource reserve status information unit to the evaluation of sustainable utilization status unit.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: First, through the resource reserve status information unit, the present invention comprehensively considers the exploited area KM, the average thickness HD, the exploited area YKM, and the average recovery rate H of the mine, realizing accurate estimation of the reserves, which helps to more accurately understand the resource status of the mine. The resource reserve change trend unit uses the difference in resource reserves after exploiting different exploited areas in the same exploited area KM in two adjacent times to calculate the reserve change rate BD, and can timely detect the increasing or decreasing trend of the reserves. Finally, the evaluation of sustainable utilization status unit comprehensively evaluates the sustainable utilization status of the reserves by calculating the reserve sustainable utilization index KC.

[0014] Second, through the reserve monitoring module and the data visualization module, the present invention can not only reflect the reserve sustainable utilization analysis after the current exploitation, but also present the historical data and real-time data in an intuitive way, thus facilitating the acquisition, management, and analysis of data.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] Regarding the management method of the mine geological resource reserves in the present invention, different from the existing management methods of mine geological resource reserves, the existing management methods of mine geological resource reserves have problems such as inaccurate reserve estimation, lack of real-time reserve change monitoring mechanism, lack of sustainable utilization assessment, and unintuitive data management and presentation. However, this algorithm unit improves the accuracy of reserve estimation, realizes real-time monitoring of reserve changes, and introduces the reserve sustainable utilization index assessment to achieve the effect of optimizing data management and presentation methods.

[0018] Example 1, please refer to Figures 1 to 2 , this embodiment provides a management method for mine geological resource reserves, including a data acquisition module, a reserve monitoring module, and a data visualization module; The specific implementation steps are as follows: Step 1: Use the data acquisition module to collect geological exploration and real-time mining monitoring of the current mine, and transmit it to the reserve monitoring module; Step 2: Use the reserve monitoring module to calculate and output the geological resource reserve Q, the reserve change rate BD, and the reserve sustainable utilization index KC in sequence, and transmit them to the data acquisition module for storage; Step 3: Based on the reserve sustainable utilization index KC, the data visualization module outputs the reserve sustainable utilization analysis after the current mining; Step 4: The data visualization module extracts the reserve sustainable utilization index KC that has occurred and been calculated in the same mine from the data acquisition module, and the data visualization module draws the sustainable utilization trend of the reserve resources; The data acquisition module includes a geological exploration unit, a mining record unit, and a monitoring sensor unit; The reserve monitoring module includes an information unit reflecting the reserve status, a unit for the change trend of the reserve resources, and a unit for evaluating the sustainable utilization status; The data visualization module includes a line graph drawing unit and a data visualization processing unit; The equipment used in the geological exploration unit includes geological exploration equipment, and is used for geological exploration and collection, including the mining area KM and the average thickness HD; The equipment used in the mining record unit includes a mining record system, and is used to record the mined area YKM, the average recovery rate HC, and the results of the geological resource reserve Q, the reserve change rate BD, and the reserve sustainable utilization index KC during each mining process; The equipment used in the monitoring sensor unit includes monitoring sensors, and is used to monitor the changes in the mine geological resources in real time; The equipment used in the line graph plotting unit and the data visualization processing unit includes data visualization software, and is used to plot the calculated reserve sustainable utilization index KC value and the historical reserve sustainable utilization index KC into a line graph; The equipment used in the reserve monitoring module includes a computer and a server, and is used for data processing and calculation from the resource reserve status information unit to the evaluation of sustainable utilization status unit.

[0019] In this embodiment, the mine geological resource reserve management method combines multiple steps and modules of data collection, reserve estimation, reserve change calculation, reserve sustainable utilization calculation, data visualization and analysis, forming a complete management system. At the same time, with the support of the equipment used, the effective management and utilization of the mine geological resource reserves are realized.

[0020] Please refer to Figures 1 to 2 , the calculation formula of the resource reserve status information unit is as follows: Q = KM × HD - YKM × HC; Where: Q is the geological resource reserve; KM is the mining area, and KM reflects the total area that can be mined within the same mine; HD is the average thickness, and HD reflects the average degree of the ore body thickness within the mining area KM; YKM is the mined area, and YKM reflects the total area of the mining area KM that has been mined up to the current; HC is the average recovery rate, and HC reflects the average situation of the actual mined mineral weight in the mined area YKM accounting for the planned mined mineral weight; KM × HD reflects the potential recoverable reserves of the entire mine; YKM × HC reflects the part that cannot be fully recovered in the mined area due to reasons including mining losses and dilution; Based on the situation reflected by KM×HD and YKM×HC, Q calculated by KM×HD - YKM×HC is the net reserve of the current resource reserve obtained by subtracting the part that cannot be fully recovered from the potential recoverable reserve.

[0021] In the information unit reflecting the resource reserve status of this embodiment, first, the part of KM×HD calculates the volume of the potential recoverable reserve of the entire mine. Among them, KM represents the mining area of the mine, which is a two-dimensional planar region, and HD represents the average thickness of the ore body, which is a one-dimensional linear measure. Multiplying the area by the thickness gives a three-dimensional volume, that is, the potential recoverable mineral resource quantity. And this product reflects the maximum recoverable resource quantity in terms of physical quantity of the mine, and it is an important basic data for evaluating the value of the mine and formulating the mining plan. Among them, the average thickness HD is obtained by dividing the current mine into N regions and then using the direct measurement method to vertically measure the thickness in each region respectively, and then using the calculation formula of i where HD is the thickness of the i-th region and N is the total number of regions; i =SL i / LL i and In the calculation of the part of YKM×HC, YKM represents the area of the mined area, and HC represents the average recovery rate of the mined area, which is a dimensionless value between 0 and 1. This product reflects the resource loss caused by various factors in the mined area, and it is an important indicator for evaluating the mining efficiency and optimizing the mining strategy. Among them, the average recovery rate HC is calculated using the two calculation formulas of HC i representing the i-th recovery rate, SL i representing the actual mining weight of the i-th time, and LL i representing the planned mining weight of the i-th time. Specifically, the actual mining weight SL i represents the mass of minerals in the ore deposit, that is, the mineral weight, directly measured and calculated by field measurement and drilling methods after each mining of different mining areas KM within the mined area area YKM. LL i The planned mining weight of the i-th time represents the mining weight manually planned by combining the actual mining weight of the previous time before each mining of different mining areas KM within the mined area area YKM; The overall calculation of the information unit reflecting the resource reserve status is the net reserve of the current mine, that is, the geological resource reserve Q remaining after subtracting the part that has been mined but not fully recovered from the potential recoverable reserve. This net reserve reflects the actual resource reserve of the mine in the current state. By regularly updating and monitoring this indicator, the resource status of the mine can be understood in a timely manner; All physical quantities in the information unit reflecting the resource reserve status have been strictly defined and the units unified, ensuring the accuracy of the reserve estimation results. This helps to more accurately understand the resource status of the mine, and the accurate reserve estimation results can provide a more scientific and reasonable numerical basis. Moreover, through the information unit reflecting the resource reserve status, the resource distribution and reserve situation of the mine can be clearly understood.

[0022] Please refer to Figures 1 to 2 , the calculation formula of the resource reserve change trend unit is as follows: ; Where: BD is the reserve change rate; Q last is the previous reserve of geological resources, Q last reflects the geological resource reserve Q calculated by using the information unit reflecting the resource reserve status after the last mining of other mining areas in the same mining area KM, and when calculating for the first time, it is set that Q last =Q, then BD = 0; Q - Q last reflects the difference in resource reserves after adjacent two times of mining different mining areas in the same mining area KM; reflects the change rate of the proportion of the difference in geological resource reserve Q last ; If the value of BD is positive, it reflects that Q is higher than Q last , and the greater the difference, the greater BD; If the value of BD is negative, it reflects that Q is lower than Q last , and the greater the difference, the smaller BD; If the value of BD is 0, it reflects that Q is equal to Q last .

[0023] In the resource reserve change trend unit of this embodiment, using the difference between Q and Q last to calculate the reserve change rate BD can reflect the increase and decrease of reserves in real time. This helps to timely discover the trend of reserve changes so as to provide a numerical basis for corresponding adjustment measures, and through real-time monitoring of the reserve changes, existing problems and situations of reserves can be discovered more quickly; Regarding the reserve change rate BD, when Q is lower than Q last , BD will be negative, which means that the geological resource reserve of the mine has decreased between the two resource reserves. When Q is higher than Q last , BD will be positive, which means that the geological resource reserve of the mine has increased between the two resource reserves.

[0024] Please refer toFigures 1 to 4 , the calculation formula for the unit of evaluating the sustainable utilization status is as follows: ; Where: KC is the sustainable utilization index of reserves; is to obtain a value between 0 and 1, and take the absolute value of KC plus 1 as the denominator to ensure that the denominator is always greater than 0 and avoid the error of dividing by 0. Taking the square root is to compress the value range so that the result is distributed between 0 and 1; is the result value of the proportion of the currently unmined area in the total area. Multiply with 's result to reflect the sustainable utilization situation within the mining area KM under the influence of the reserve change rate BD on the currently unmined area.

[0025] In the unit of evaluating the sustainable utilization status of this embodiment, first In the calculation part, taking the absolute value of the reserve change rate BD is to ensure that a non - negative value can be obtained regardless of whether BD is positive or negative. This is because the increase and decrease of reserves should have the same impact degree in evaluating the sustainable utilization index, only in different directions. Taking the absolute value of BD plus 1 as the denominator is to ensure that the denominator is always greater than 0, thus avoiding the error of dividing by 0 in mathematical operations. At the same time, adding 1 also plays a smoothing role, so that when the absolute value of BD is very large, its impact will not be too drastic. Taking the square root is to further compress the value range and make it more compactly distributed between 0 and 1. The advantage of this is that it can make the value of KC more sensitive to the change of BD, and even if BD has a slight change, the value of KC will be adjusted accordingly; The calculation result of this ratio reflects the richness of the remaining resources in the mine. The higher the proportion of the unmined area, that is, the value is higher than , it indicates that the remaining resources in the mine are more and the sustainable mining time is longer. On the contrary, it indicates that the mine resources are approaching exhaustion; The unit of evaluating the sustainable utilization status The overall calculation is the reserve sustainable utilization index KC, which synthesizes two factors: the reserve change rate BD and the proportion of the currently unmined area. The closer the value of the reserve sustainable utilization index KC is to 1, the better the sustainable utilization status of the reserves; the closer it is to 0, the worse the status. By regularly calculating and monitoring the value of the reserve sustainable utilization index KC, the resource status of the mine can be understood in a timely manner. Additionally, it should be noted that if, during a certain period, the value of the sustainable utilization index KC tends to level off and the reserve change rate BD in the resource reserve change trend unit changes from a positive value to a negative value, it indicates that the resource reserve is decreasing steadily. At this time, this cannot be prominently reflected from the change in the value of the sustainable utilization index KC. Therefore, during the process of reserve management, it is necessary to observe the reserve change rate BD and the sustainable utilization index KC together; The level of the reserve sustainable utilization index KC calculated by the evaluation of the sustainable utilization status unit directly reflects the efficiency of the mine resource utilization. Through the reserve sustainable utilization index KC, the utilization status of the mine resources can be clearly understood, so as to take measures for optimization in a timely manner. The cyclic influence mechanism in the evaluation of the sustainable utilization status unit enables the reserve sustainable utilization index KC to be associated with and affect the key parameters of the mined area area YKM. Specifically, based on the current reserve sustainable utilization index KC, when formulating the next mining area, it affects the specific increase in the mined area area YKM. This helps to more comprehensively consider various factors when formulating the sustainable utilization strategy to ensure the feasibility and effectiveness of the strategy. Through continuous monitoring and evaluation, problems existing in the utilization of mine geological resources can be discovered and solved in a timely manner.

[0026] Example two, please refer to Figures 3 to 4 , the analysis based on the calculation results of the reserve sustainable utilization index KC is as follows: When the value of BD is negative and the difference between Q and Q last is large, the value of KC will approach 0, indicating that the reserve resources are decreasing and the sustainable utilization amount is decreasing; When the value of BD is positive and the difference between Q and Q last is small, the value of KC will approach 1, indicating that the reserve resources are increasing and the sustainable utilization amount is increasing; When the value of BD is 0, the value of KC is 0, indicating that the reserve resources are stable and the sustainable utilization amount is stable; Based on the reserve sustainable utilization index KC, all the reserve sustainable utilization indices KC for the same mined area KM obtained from each calculation are collected and managed by the data acquisition module, and the data visualization module is used for the drawing management of the line graph. The specific analysis presented after the management and drawing is as follows: If the reserve sustainable utilization index KC shows a continuous upward trend on the line graph, it reflects that the exploited resources within the current exploited area KM are abundant; If the reserve sustainable utilization index KC shows a continuous downward trend on the line graph, it reflects that the exploited resources within the current exploited area KM are approaching exhaustion; If the reserve sustainable utilization index KC shows a continuous flat trend on the line graph, it reflects that the exploited resources within the current exploited area KM are abundant.

[0027] In this embodiment, the current reserve sustainable utilization index KC can immediately reflect the sustainable utilization status of the mine geological resource reserves. When the reserve sustainable utilization index KC is high, it indicates high reserve utilization efficiency, relatively abundant resources, and good mine operation status. On the contrary, if the reserve sustainable utilization index KC is low, it means that the reserves are decreasing rapidly and the exploitation efficiency is not high. By monitoring the change of the reserve sustainable utilization index KC, potential risks in reserve utilization can be discovered in a timely manner; And this embodiment combines the historical reserve sustainable utilization index KC to be able to draw a line graph and show the change trend of the reserve sustainable utilization index KC over time. This helps to understand the long-term development trend of mine reserve utilization. Through trend analysis, the laws of periodic changes and seasonal fluctuations in reserve utilization can be discovered, and by comparing the reserve sustainable utilization index KC in different time periods, the effectiveness of the reserve management strategy can be evaluated. If new mining technologies and management measures are adopted in a certain period and result in a significant increase in the reserve sustainable utilization index KC, it means that these measures are effective. On the contrary, if the reserve sustainable utilization index KC continues to decline, the existing management strategy needs to be reflected on; So far, by simultaneously observing the current and historical reserve sustainable utilization index KC, this embodiment can more comprehensively understand the utilization status of the mine reserves, and provide a numerical basis for reasonably allocating exploited resources according to the feedback of the reserve sustainable utilization index KC, while avoiding resource waste and over-exploitation. By monitoring the change trend of the reserve sustainable utilization index KC, potential risks in reserve utilization can also be discovered and addressed in a timely manner, thereby reducing the uncertainty of mine operation; In summary, the results presented by simultaneously observing the current and historical reserve sustainable utilization index KC can provide strong data support for the management of mine geological resource reserves, help improve management efficiency, optimize resource allocation, enhance risk management capabilities, and promote sustainable development.
