[0003] Deeply buried metal mines often employ blasting or subsequent backfilling mining. During the mining process, ore and rock bulk materials need to be transported from the bottom of the ore and rock bulk accumulation. Achieving efficient transport of ore and rock bulk materials and reducing the dilution rate of these materials is one of the core indicators in the design of ore and rock bulk material extraction in the stope. However, the movement of ore and rock bulk materials during on-site transport remains a "black box problem," making it difficult to obtain the movement patterns through on-site testing. This makes it impossible to provide data on the movement and size of ore and rock bulk materials for efficient transport of metal mine ore, thus affecting the efficiency of ore and rock bulk material extraction in the stope. Summary of the Invention

The ore and rock are screened by different particle sizes using the bulk block size module to obtain the mass distribution of ore and rock with different particle sizes and transmit it to the processor. The image acquisition device is set above the bulk transport device and is used to acquire images of ore and rock in different transport states and extract the overall contour curves and marker particle contour curves of ore and rock in different transport states. It is used to depict the overall image of the accumulation morphology of ore and rock during the transport process, and then obtain the overall change characteristics of ore and rock and transmit them to the processor. The processor is also configured to: Real-time reception of the force parameters and spatial displacement parameters of each mineral and rock aggregate marker particle under different transport conditions; Based on the mass distribution of ore and rock granules with different particle sizes, and compared with the calibrated mass of ore and rock granules, the gradation and dilution rate parameters of ore and rock granules at different excavation stages are obtained in real time as the ore and rock granules are transported.

The ore and rock bulk are screened by different particle sizes using the bulk block size module to obtain the quality distribution of ore and rock bulk with different particle sizes. The quality is compared with the calibrated ore and rock bulk.

[0014] As one implementation method, the overall variation characteristics S of the ore-rock mass, the force parameter F of the ore-rock mass marker particles, the spatial displacement parameter V, the depletion rate P, and the block size parameter N are all dimensionless. The ore-rock mass migration evaluation index is set as follows: Y ( n ): Y ( n )= a s ( n )+ b [ p ( n )+ g ( n )]+ c [ v ( n )+ f ( n )]; ; ; ; ; ; in, a These are the parameters for fitting the macroscopic curve of the ore-rock granular material. b These are the fitting parameters for the characteristics of ore-rock granules. cThese are fitting parameters for the motion characteristics of ore-rock granules. , , , and These are related to the number of excavations.

The ore and rock bulk size characteristic acquisition module is used to determine the quality parameters of ore and rock bulk by quality calibration of the mined ore body. The bulk size module is used to screen the ore and rock bulk with different particle sizes to obtain the quality distribution of ore and rock bulk with different particle sizes, and compare it with the calibrated ore and rock bulk quality. As the ore and rock bulk is transported, the gradation and dilution rate parameters of ore and rock bulk at different excavation stages are analyzed in real time. The spatiotemporal transport model construction module is used to generate a spatiotemporal transport model of ore and rock based on the overall change characteristics of ore and rock, the stress parameters and spatial displacement parameters of the marker particles of ore and rock, and the gradation and depletion rate parameters of the ore and rock at different excavation stages, so as to realize the quantitative and visual analysis of the spatiotemporal transport of ore and rock.

[0026] according to Figure 1 and Figure 2 This invention provides a system for evaluating the spatiotemporal transport of ore and rock, comprising: a model test frame 1 for the spatiotemporal transport of ore and rock, a transport device, an image acquisition device 5, and a processor; ore and rock are arranged within the model test frame 1 for the spatiotemporal transport of ore and rock. The bulk transport device is connected to the bottom of the test frame 1 for the spatiotemporal transport model of ore and rock. It is used to transport the ore and rock within the test frame 1. The quality parameters of the ore and rock are determined by quality calibration of the mined ore body. The ore and rock are screened by different particle sizes using the bulk block size module to obtain the mass distribution of ore and rock with different particle sizes and transmit it to the processor. Image acquisition device 5 is set above the bulk transport device to acquire images of ore and rock in different transport states and extract the overall contour curve and marker particle contour curve of ore and rock in different transport states. It can also perform an overall image characterization of the accumulation morphology of ore and rock during transport, thereby obtaining the overall change characteristics of ore and rock and transmitting them to the processor. The processor is also configured as follows: Real-time reception of the force parameters and spatial displacement parameters of each mineral and rock aggregate marker particle under different transport conditions; Based on the mass distribution of ore and rock granules with different particle sizes, the gradation and dilution rate parameters of ore and rock granules at different excavation stages are obtained through real-time analysis as the ore and rock granules are transported. Based on the overall variation characteristics of ore and rock mass, the stress parameters and spatial displacement parameters of the marker particles of ore and rock mass, and the gradation and depletion rate parameters of the mass at different excavation stages, a spatiotemporal transport model of ore and rock mass is generated to achieve quantitative and visual analysis of the spatiotemporal transport of ore and rock mass.

[0027] In the specific implementation process, the bulk material transportation device includes a bulk ore discharge guide rail 2 and a bucket device 3 and a bulk ore grading device 4 set on the bulk ore discharge guide rail 2; the bulk ore discharge guide rail 2 is connected to the bottom of the bulk ore spatiotemporal transport model test frame 1, the bucket device 3 is used to scoop and transport bulk ore; the bulk ore grading device 4 is used to weigh and screen the bulk ore in a timely manner.

[0028] In the specific implementation process, it is first necessary to obtain the basic geological parameters of the ore and rock bulk material, the ore discharge design, and the ore body grade to calibrate the size, shape, and quality parameters of the ore and rock bulk material for the test. Then, a spatiotemporal transport model device for the ore and rock bulk material is fabricated. The device dimensions are further scaled down according to the on-site ore discharge design, and the basic block size characteristics of the bulk material are determined based on the ore discharge design. Subsequently, a transparent PTFE plate is used to fabricate the model test device to ensure visualization of the spatiotemporal transport process of the ore and rock bulk material. During installation, the dimensions and spacing of the bottom roadway of the spatiotemporal transport model test frame 1 of the ore and rock bulk material are determined according to the on-site ore discharge design, and the side plates are roughened to simulate the frictional conditions of bulk material transport in the on-site stope.

[0029] Based on the geological conditions of the ore and rock mass at the site, by adjusting the proportions of cement, sand and water, spatiotemporal transport marker particles for ore and rock mass are prepared so that the basic mechanical parameters of the spatiotemporal transport marker particles are similar to those of the ore and rock mass at the site. During the preparation process, spatial displacement sensors and wireless stress sensors are pre-embedded inside the spatiotemporal transport marker particles, so as to output spatial displacement and force information during the transport of ore and rock mass.

[0030] Based on the on-site geological conditions and ore extraction design, the gradation of the ore and rock mass was designed to make the gradation of the ore and rock mass used in the test similar to that of the ore and rock mass on site. Subsequently, the graded ore and rock mass was arranged at a set height in the test frame 1 of the ore and rock mass spatiotemporal transport model. During the arrangement process, ore and rock mass spatiotemporal transport marker particles were arranged at different heights, and the initial displacement parameters and stress parameters of the ore and rock mass spatiotemporal transport marker particles were calibrated.

[0031] After the ore and rock bulk material is laid out, the image acquisition device 5, the bucket device 3, and the processor are turned on to conduct a bulk material transport test during the ore and rock bulk material transportation process. During the test, the bucket device 3 enters the bottom roadway of the ore and rock bulk material spatiotemporal transport model test frame 1 through the ore and rock bulk material discharge guide rail 2, excavates the ore and rock bulk material, and transports the bucket device 3 to the ore and rock bulk material grading device 4 through the ore and rock bulk material discharge guide rail 2. The ore and rock bulk material grading device 4 is equipped with a screen and a weight sensor, and can move back and forth on the ore and rock bulk material discharge guide rail 2 to screen the bulk material in the bucket device 3 and obtain the mass of ore and rock bulk material of different particle sizes, so as to obtain the block size characteristics of ore and rock bulk material at different excavation stages and calculate the dilution rate.

[0032] The image acquisition device 5 collects two types of information: the overall outline information of the ore and rock mass and the information of the marker particle layer. During the shoveling process of the bucket device 3, the movement of the ore and rock mass exhibits both continuous and discontinuous characteristics. That is, the shoveling process is continuous, but each shoveling operation is discontinuous. Taking the number of shoveling operations of the bucket device 3 as a variable, each shoveling operation and each group of shoveling operations (with a fixed number of shoveling operations per group) sketches the above two types of information. Through image analysis, information such as area and curvature is calculated to achieve an overall description of the ore and rock mass characteristics.

[0033] During the transport process of the bucket device 3, with different transport times (n) as variables, the image acquisition device 5 collects real-time images of the ore and rock mass through the ore and rock mass test frame, draws the overall morphological outline of the ore and rock mass, and delineates different transport stages of the ore and rock mass. Simultaneously, the ore and rock mass marker particles inside the ore and rock mass output the displacement and stress characteristics of the internal ore and rock mass in real time, enabling the realization of the macroscopic and microscopic correspondence characteristics of the ore and rock mass during the transport process. Based on this, the bucket device 3 outputs the gradation characteristics and dilution rate of the ore and rock mass during transport in real time.

[0034] In the processor, the overall variation characteristics of the ore and rock mass are set as S, the force parameter of the ore and rock mass marker particles is set as F, the spatial displacement parameter is set as V, and the gradation and dilution rate parameters of the ore and rock mass include the dilution rate P and the block size parameter N. All of the above parameters are functions of the number of excavations n.

[0035] The overall variation characteristics S of the ore-rock mass, the stress parameter F of the ore-rock mass marker particles, the spatial displacement parameter V, the dilution rate P, and the block size parameter N were all dimensionless. The ore-rock mass migration evaluation index was set as follows: Y ( n ): Y ( n )= a s ( n )+ b [ p ( n )+ g ( n )]+ c [ v ( n )+ f ( n )]; in: ; It describes the process of change from the initial state to the final stable state, gradually approaching a limit value.

[0036] ; The physical meaning is as follows: In the early stage, pure ore is released, P ≈ 0; in the middle stage, waste rock begins to be mixed in, and P rises rapidly; in the later stage, it is almost all waste rock, and P approaches 1 or the maximum waste rock mixing rate.

[0037] ; The physical meaning is: as the number of excavations increases, the internal damage of the rock mass accumulates, making it easier to generate fine particles in subsequent excavations, reflecting the process of rock mass fatigue or damage accumulation.

[0038] ; The physical meaning is as follows: In the initial stage: the particles are in equilibrium and need to overcome a certain frictional or interlocking force to start moving; the initial displacement is very small. ); Flow stage: Once the critical state is exceeded ( The particles begin to flow continuously, and the displacement increases rapidly; in the controlled stage: if boundary constraints are encountered or a stable flow arch is formed, the displacement will tend to saturate. ).

[0039] ; The physical meaning is as follows: In the initial stage of excavation (unloading), the force on the particles is released rapidly (force chain breaks), and F decreases rapidly; as the bulk material is rearranged, a brief force chain reconstruction (small peak value) may occur locally; overall, the stress tends to a certain residual stress value as the number of excavations increases. .

[0040] in, a These are the parameters for fitting the macroscopic curve of the ore-rock granular material. b These are the fitting parameters for the characteristics of ore-rock granules. c These are fitting parameters for the motion characteristics of ore-rock granules. , , , and These are related to the number of excavations. The overall variation characteristic function, dilution rate function, block size parameter function, spatial displacement parameter function, and stress parameter function of the ore-rock granular material; This represents the maximum value corresponding to the overall variation characteristics of the ore-rock mass; This is the initial value corresponding to the block size parameter; This represents the maximum value corresponding to the spatial displacement parameter; This represents the residual stress value. The critical number of excavations; , , , , , , and All are constant coefficients.

[0041] It should be noted here that, , , , , , , and These constant coefficients can be set according to the actual situation, or determined by fitting a set number of experimental data sets.

[0042] The transport process of ore and rock bulk materials is quantitatively evaluated by using macroscopic and internal particle parameters. The ore and rock bulk material transport evaluation index Y specifically characterizes the internal movement and force parameters of the bulk materials during transport, the size and depletion rate of the particles during bucket transport, and the overall transport law of the ore and rock bulk materials. This index allows for a comprehensive evaluation of the overall transport of the bulk materials under different variable conditions in various ore and rock bulk material transport tests. For example, by changing the particle size distribution, layered arrangement, and overlying load in the spatiotemporal transport test of ore and rock bulk materials, the test results can be comprehensively evaluated using the ore and rock bulk material transport evaluation index Y, providing feedback to optimize the blasting and transport design of the mining area. A larger ore and rock bulk material transport evaluation index Y indicates a better transport effect in the ore and rock bulk material transport test, providing guidance for on-site mining area design.

[0043] This embodiment, through the development of spatiotemporal transport experiments of ore and rock bulk materials, can collect the macroscopic contour and movement conditions of ore and rock bulk materials in real time. Combined with the bucket device, it can output the block size characteristics of ore and rock bulk materials in real time, obtain the gradation changes and dilution rate of ore and rock bulk materials, provide bulk material transport and block size data for the efficient transport of metal ore and rock bulk materials, and provide data and model support for the transport design of ore and rock bulk materials.

[0044] In one or more embodiments, a method for evaluating the spatiotemporal transport of ore-rock aggregates is provided, wherein the ore-rock aggregates are modeled using marker particles made of similar materials and sensing elements, and whose mechanical properties are similar to those of the rock mass in the field, simulating pre-set field conditions; the method may include the following steps: Step 1: Obtain images of ore and rock in different transport states and extract the overall contour curves and marker particle contour curves of ore and rock in different transport states. Describe the overall image of the accumulation morphology of ore and rock during transport process, and then obtain the overall change characteristics of ore and rock.

[0045] Let S be the overall variation characteristics of the ore-rock mass. ; Regarding the number of excavations The overall variation characteristic function of ore-rock granules; This represents the maximum value corresponding to the overall variation characteristics of the ore-rock mass; These are constant coefficients, which can be obtained through data fitting.

[0046] Step 2: Real-time acquisition of the force parameters and spatial displacement parameters of each mineral and rock mass marker particle under different transport conditions.

[0047] The force parameter of the ore and rock aggregate marker particles is set as F, and the spatial displacement parameter is set as V; ; ; in, and These are related to the number of excavations. Spatial displacement parameter function and force parameter function.

[0048] This is the initial value corresponding to the block size parameter; This represents the residual stress value. , , , , and All of these are constant coefficients, which can be obtained through data fitting. This represents the critical number of excavations.

[0049] Step 3: Determine the quality parameters of ore and rock by quality calibration of the mined ore body, and use the ore and rock block size module to screen the ore and rock at different particle sizes to obtain the quality distribution of ore and rock at different particle sizes. As the ore and rock are transported, the gradation and dilution rate parameters of ore and rock at different excavation stages are analyzed in real time.

[0050] The gradation and dilution rate parameters of ore-rock granules include the dilution rate P and the block size parameter N; ; ; in, , Regarding the number of excavations The depletion rate function and the block size parameter function. This is the initial value corresponding to the block size parameter; , All of these are constant coefficients, which can be obtained through data fitting. This represents the critical number of excavations.

[0051] Step 4: Based on the overall change characteristics of ore and rock mass, the stress parameters and spatial displacement parameters of the marker particles of ore and rock mass, and the gradation and depletion rate parameters of the mass at different excavation stages, generate a spatiotemporal transport model of ore and rock mass to achieve quantitative and visual analysis of the spatiotemporal transport of ore and rock mass.

[0052] The overall variation characteristics S of the ore-rock mass, the stress parameter F of the ore-rock mass marker particles, the spatial displacement parameter V, the dilution rate P, and the block size parameter N were all dimensionless. The ore-rock mass migration evaluation index was set as follows: Y ( n ): Y ( n )= a s ( n )+ b [ p ( n )+ g ( n )]+ c [ v ( n )+ f ( n )]; in, a These are the parameters for fitting the macroscopic curve of the ore-rock granular material. b These are the fitting parameters for the characteristics of ore-rock granules. c These are the fitting parameters for the motion characteristics of ore and rock granules.

[0053] It should be noted that the order of steps 1, 2, and 3 can be adjusted arbitrarily according to the actual situation.

[0054] In other embodiments, a system for evaluating the spatiotemporal transport of ore and rock bulk materials is provided, comprising: The module for acquiring the overall features of ore and rock bulk is used to acquire images of ore and rock bulk in different transport states and extract the overall contour curves and marker particle contour curves of ore and rock bulk in different transport states.

The ore and rock mass motion characteristic acquisition module is used to acquire the force parameters and spatial displacement parameters of each ore and rock mass marker particle under different transport conditions in real time. The ore and rock bulk size characteristic acquisition module is used to determine the quality parameters of ore and rock bulk by quality calibration of the mined ore body. The bulk size module is used to screen the ore and rock bulk with different particle sizes to obtain the quality distribution of ore and rock bulk with different particle sizes. As the ore and rock bulk is transported, the gradation and dilution rate parameters of ore and rock bulk at different excavation stages are analyzed in real time. The spatiotemporal transport model construction module is used to generate a spatiotemporal transport model of ore and rock based on the overall change characteristics of ore and rock, the stress parameters and spatial displacement parameters of the marker particles of ore and rock, and the gradation and depletion rate parameters of the ore and rock at different excavation stages, so as to realize the quantitative and visual analysis of the spatiotemporal transport of ore and rock.
