Meanwhile, the digital mining plan can also quickly realize the planning mining plan and the quick adjustment in any period (year, month, day and team). The Wuhouzijin can obtain more than 200 ten thousand effective data by developing digital mining planning, which is more than 100 times of the traditional front manual planning data, thereby greatly improving the planning precision and accuracy.
4. The drawing of the three-dimensional excavation plan progress drawing and the three-dimensional design drawing and the printing of the traditional CAD manual excavation plan drawing only have graphic information but no attribute information, so that the manually drawn excavation drawing is not only low in efficiency, but also cannot be drawn strictly according to the excavation plan. The drawing of the excavation drawing can be rapidly completed by adopting the digital three-dimensional excavation progress diagram. Through developing three-dimensional design research and three-dimensional drawing printing technology, the black-back purple gold distinguishes the traditional CAD drawing mode, frequent section cutting and various report form compiling are avoided, drawing efficiency and drawing readability are greatly improved, and revolutionary progress of an engineering drawing mode is completed.

Determining the attribute information carried by the ore block: the common attribute information comprises information such as an estimated value result, ore type, ore weight, resource/reserve level and the like.
The size of the ore block is comprehensively determined according to conditions such as geostatistics characteristics, prospect engineering intervals, mining constraints, geological factors, terrain, computer processing capacity and the like, for example, for a thin-layer ore deposit with suddenly changed grade, the size of the ore block is smaller as much as possible, and for an ultra-thick gradient ore deposit, the size of the ore block is larger. In consideration of mining engineering, the size of the ore block should be directly multiplied with the mining engineering such as the size of a chamber, the height of an open-pit mining step and the like as far as possible, and the elevation value of the center point of the ore block is multiplied with the elevation of the mining step. Typically, the maximum nugget size should be no greater than 1/4 for the minimum prospect interval.
The octree model is adopted to construct the ore block model, so that the ore block model can form unit blocks with corresponding sizes under each scale, and the ore block model has information of element grade, ore quantity and the like under each scale.

Samples are processed in a long way, and the geostatistical estimation method requires that the samples be equal in length, so that each sample represents equal weight.

For example, for a certain mineral, the average value of the sample length is 1.6556 meters through the basic statistical analysis of the sample length. If the samples with the original sample length of 1.5 m are the most, the sample combination length of the current sample is 1.5 m on the principle of using the original information of the samples as much as possible, and the samples in the ore body are subjected to isometric treatment.

The elements become vertices, and the elements in the finite set E are called edges, each edge between a pair of vertices. If of figure G
The edge is between the ordered vertex pair, so the G is called a directed graph or a directed graph, and the topological network of the production plan is advanced according to a certain direction, so the network graph of the production plan is actually a directed graph.
According to the mining production planning and planning requirements, a plurality of data tables are required to be established and defined for storing data related to a production plan, so that the plan centralized storage management of different periods and different process procedures is facilitated, the data intercommunication between a medium-long-term plan and a short-term plan is realized, and the data intercommunication between the plan data and the production data is realized.

Wherein the plan constraints include four relationships:
1) constraints between basic tasks of the roadway (headway constraints);
2) constraints between stope base tasks (stope-to-stope constraints);
3) constraints between roadway and stope tasks (interbore constraints);
4) deriving constraints between tasks (inter-process constraints);

The decision variables of the medium-and-long-term mining plan model are divided into a first-stage mining field and a second-stage mining field by analyzing the mining process of the underground metal mine and taking ore blocks as units in order to reduce the complexity of the model, the binary decision variables of the medium-and-long-term mining plan model are taken as mining according to the mining field position, the mining time and the production capacity, and the value of 1 is defined when a mining field a begins to perform mining with n production capacity in the period t, otherwise, the value is 0, namely:
ge -: the grade of element e is less than the deviation of the minimum grade requirement;
ge +: the grade of element e is greater than the deviation required by the maximum grade;
the conditional constraint of the medium-and-long-term mining planning model can be based on the medium-and-long-term mining planning production conditions of the underground metal mine, after determining the objective function and the decision variables of the mixed integer planning model, relevant constraints need to be added to the planning model, such as mining variable constraint, mining logic constraint, ore-out level constraint, total production capacity constraint, in-layer sequential mining constraint, in-layer simultaneous mining quantity constraint, inter-layer sequential mining constraint, two-step constraint in ore blocks and the like, and the specific constraint establishment mathematical expression can be established according to the actual conditions of each ore.
The invention further constructs a short-term mining plan model:
according to the formulation principle of the short-term mining plan of the underground metal ore, the minimum sum of the mining grade and the target grade deviation value of each element in the monthly mining project is selected as a target function, the method has the advantages that the fluctuation of the ore grade can be reduced to reduce the subsequent work consumption, the economic benefit of an enterprise is improved, and the mathematical expression of the target function is as follows:
wherein t is an index of mining time; t is a set of times; lambda [ alpha ]tThe weight coefficient is more than 0 and is t time, and the weight coefficient determines the priority of the mineral separation grade at different time intervals;
deviation of time t less than required gradeA value;
the time t is greater than the deviation value of the required grade; because of the fact that
Are all non-negative numbers, so that in the same time t

The invention constructs the middle-term and short-term mining models through various data tables and models, facilitates the middle-term and long-term and short-term generation and planning of the mine, and improves the sustainable production capacity of the mine, which is another important invention point of the invention.
In addition, the traditional mining plan adjustment is based on three-dimensional original data manual adjustment, and in order to quickly realize the mining plan adjustment, the invention develops the technology for adjusting the mining plan based on the Gantt chart. In order to facilitate the checking of the task completion condition at the current time, the Gantt chart is developed with the function of automatically counting the completed quantity, and the corresponding engineering information displayed on the Gantt chart is complex, so that a network chart display technology corresponding to the Gantt chart is developed, and the corresponding information can be visually seen through the network chart display. The Gantt chart can directly display the logical relation between the tasks before and after the tasks, the tasks before and after the tasks can be multiple, the functions of Gantt chart dragging, compression and pull-up adjustment are developed for quickly adjusting the logical sequence between the tasks, and the logical sequence between the tasks is quickly changed by adopting an intuitive method. The Gantt chart dragging adjustment function is directly changing the starting time and the ending time of the task and the logic sequence, and does not change the duration time and the planning quantity of the task. And dragging the Gantt chart forwards, wherein the task immediately behind and the task immediately before the task are not changed, and the maximum dragging range is that the task immediately before in the task completes the task at the latest. Gantt chart task compression and stretching does not change the task start time and schedule amount, but changes to the task duration. The Gantt chart task is compressed forwards, the task is unchanged immediately after, the starting time is unchanged, and the duration is reduced, which is another important invention point of the invention.
Generating a mining plan according to the mining plan compiling requirement, customizing and compiling 10 fixed report tables: the method comprises the following steps of heading schedule, engineering type heading schedule, roadway start-stop time schedule, heading schedule statistics schedule, mining schedule edge, mining schedule, filling schedule, financial summary schedule, geological drilling schedule and geological drilling statistics schedule. The generation method comprises the following steps: and reading the data required to be displayed by each report form from the database and the production path through the iSchedule software, and storing the data in the memory of the computer. Automatically creating an Excel file and a workbook in an xlsx format in a selected file path by using a packaged function interface, adding an independent worksheet for each report in the workbook according to options selected in a user function interface, setting formats such as a header, a font, a frame line, an alignment mode, a freezing row and column of the report, and writing data into the corresponding worksheet of the Excel file.
Because the mining plan report has very fine data, the data table is huge (about 200 ten thousand data in 10 tables) and is not intuitive, so that the user cannot obtain the mining plan compilation result quickly and further cannot judge whether the mining plan compilation result is correct or not quickly. In order to solve the problems that a mining plan data report is not visual and data is huge, the invention researches and develops a technology for rapidly counting report data in a graphic mode, develops a three-dimensional progress chart generating function of a mining plan in order to visually display the space production condition of the mining plan in a period time, and mainly solves the problem of drawing a mining engineering drawing. The realization principle is as follows: calculating the propulsion range within the current period time according to the period planning data generated by the software three-dimensional mining animation and the generated path direction, then cutting on the basis of the original ore body model, and performing color matching on the ore body model cut in each period according to the period color set by the user. For the generated mining plan progress model, a user can select to generate a periodic progress graph and label information into a periodic layer, or save the periodic progress graph and the label information as a plurality of periodic progress dmf files by taking a period as a unit. The software animation playing is divided into automatic animation playing and manual animation playing. When the animation is automatically played, the software automatically reads the models from small to large according to the period and sequentially displays the models in the three-dimensional view according to a certain time interval; when the animation is played manually, the user can freely click the buttons of the previous step and the next step to control and display the periodic state of the ore body model. The animation result can be exported into an animation file in a dma format, the json format is adopted in the animation file, data such as the cycle name, the number of ore body slices, the point coordinates, the labeling information and the like of each cycle are stored, and the domestic plan scheduling software is mainly characterized by not only displaying the mining cycle animation, but also displaying the mining plan task amount of each cycle in a rolling manner, which is another important invention point of the invention.
In the invention, the standard printout of mine excavation drawings is as follows: through layout and template files. The engineering drawing essentially comprises the steps of generating corresponding graphic data by using model data and primitive data through an algorithm and an index, and displaying and outputting the graphic data on a drawing according to a certain spatial layout mode until the data meet the relevant requirements of a specific drawing. The main technical process of templated drawing is as follows: through a manual plotting process, information such as an element generation mode, a model algorithm processing mode, relative spatial positions of data and the like in the process is used for generating a template data file through an XML text, and when the same type of graph paper is output next time, corresponding graph files under different layouts are automatically generated by referring to configuration information stored in the XML file.
In order for the template file to correctly process the graph information, the following data needs to be saved in the template file:
1. and saving the geometric algorithm in the chart flow. Processing the model data content will generate different data in the layout plane according to the layout plane spatial position. Generally, different maps have different layouts, such as a planar layout of a planar geological map, a profile layout in a geological profile, and the like. In addition, the generation of the map is also influenced by different geometric algorithms, such as a geological plan which cuts the ore body in a plane layout. Because the three-dimensional model and the layout need to be edited manually, the geometric algorithm used in the diagram flow is saved, and the template can automatically process the three-dimensional model data according to the layout plane to generate the required diagram information.
2. And storing the space coordinates of the three-dimensional model data. The three-dimensional model data is used as the core of the graph, and any other graphic primitive is generated according to the position of the three-dimensional model data, so that each space coordinate of the three-dimensional model data, including a graph center, a minimum outsourcing rectangle and the like, must be recorded in the template. If the three-dimensional model data form is scattered, a plurality of parts are stored in batches to ensure that the primitive data are generated correctly.
3. And saving the attribute and the relative spatial position of the primitive data. The primitive data is divided into two types, one type is independent of attribute elements, such as north pointers, signatures, and the like. Such primitive data is mainly generated depending on spatial positions. Another type of primitive is hooked to attribute elements, such as drill holes, that are generated based on attribute elements of a particular geologic volume. Such a drawing therefore requires the corresponding attribute information to be stored.
In the research of the digital three-dimensional drawing printing technology, mining design and mining planning are developed in a three-dimensional visual environment, all design and planning results are three-dimensional space data, and therefore, the direct printing of a vectorized three-dimensional stereogram with any visual angle is supported. Certainly, the vectorized three-dimensional stereo image is adjusted to have an observation angle and is finally printed on a paper drawing to be a two-dimensional drawing, the spatial relationship among all elements can be more visually reflected through transparency adjustment, character marking and data sheet statistics, and the rationality of the achievement scheme is favorably examined. The Wuhou Zijin 2020-2023 year 630m middle section mining plan three-dimensional drawing applying the invention comprises a three-dimensional mining progress drawing, a data statistical table, a chart label, a legend and the like, wherein the three-dimensional mining drawing is the 1 st three-dimensional mining period progress drawing in the international and domestic world, and geological drilling design and mining monomer design three-dimensionality are realized in the early 6 months in 2020. The three-dimensional design is developed to get rid of the defect of a two-dimensional design space, the time for frequently cutting the section, counting a coordinate table of a control point and counting the engineering quantity is reduced, and the drawing efficiency is greatly improved, which is another important invention point in the invention.
By implementing the method of the invention, the invention can achieve the following technical effects:
1. the method realizes the accurate calculation of the depletion indexes of complex multi-ore body mines in the three-dimensional environment, and the traditional depletion index calculation can only be analyzed after stope recovery is finished. Because personnel can not enter the stope to measure the goaf in the stope production process, the ore discharge amount statistics or the filling amount conversion can be carried out only after the stope is finished, and the corresponding depletion index is calculated. And the goaf modeling and the software depletion index calculation module realize the accurate calculation of the depletion index of the stope.
2. The method has the advantages that a dynamic analysis and management system of the depletion index of the underground mine is realized, the depletion rate of the Sangui ore is reduced to 15.3% and the loss rate is 13.8% before the digital three-dimensional depletion index analysis is carried out, the dynamic depletion index analysis method is adopted, and mining design and process management are enhanced, for example, the depletion rate of the Sangui ore is reduced to 14.5%, the loss rate is reduced to 12.5%, the ore is recycled more than 4.3 wt% in years, more zinc metal is recycled more than 1340t, more lead metal is recycled more than 280t, and the annual economic benefit is increased more than 1600 ten thousand yuan.
3. The research of digital mining planning and key technology thereof is completed, and the research and development of a four-bit linked underground mine mining planning system of 'three-dimensional model-Gantt chart-network chart-data table' are used for completing the mining planning tasks of Wuhou Zijin 330wt/a relating to more than 200 stopes and 2200 various types of roadways, and realizing various achievement display modes of scheduling parameter batch processing, planning linkage planning and staged mining chart automatic generation, report automatic generation and statistics, three-dimensional visual animation, Gantt chart and the like. The traditional excavation planning needs more than ten professional technicians to carry out planning of two months in a period (about 600-700 workers), while the excavation planning can be completed by only 5-6 persons through 8-10 days by adopting digital excavation planning (about 50-60 workers), so that the labor is saved by more than 85%, and the planning efficiency is improved by more than 5 times. Meanwhile, the digital mining plan can also quickly realize the planning mining plan and the quick adjustment in any period (year, month, day and team). The Wuhouzijin can obtain more than 200 ten thousand effective data by developing digital mining planning, which is more than 100 times of the traditional front manual planning data, thereby greatly improving the planning precision and accuracy.
4. The drawing of the three-dimensional excavation plan progress drawing and the three-dimensional design drawing and the printing of the traditional CAD manual excavation plan drawing only have graphic information but no attribute information, so that the manually drawn excavation drawing is not only low in efficiency, but also cannot be drawn strictly according to the excavation plan. The drawing of the excavation drawing can be rapidly completed by adopting the digital three-dimensional excavation progress diagram. Through developing three-dimensional design research and three-dimensional drawing printing technology, the black-back purple gold distinguishes the traditional CAD drawing mode, frequent section cutting and various report form compiling are avoided, drawing efficiency and drawing readability are greatly improved, and revolutionary progress of an engineering drawing mode is completed.
