Description

Technical Field

[0001] This application relates to the field of mineral mining technology, and in particular to a method and related apparatus for loading explosives in a radioactive mine. Background Technology

[0002] Open-pit blasting is a preliminary process in open-pit mining. During open-pit mining, blasting is used to break the ore body into pieces that can be excavated or transported. To improve the energy utilization rate of explosives, the explosives loaded into the blast holes in open-pit mines need to be matched with the grade of the blast holes (different mineral contents correspond to different grade types). For example, in areas with lower ore grades and mainly waste rock, the energy released by the explosives can be higher to enhance rock breaking and dispersion, thereby improving subsequent mining efficiency.

[0003] In special mines with radioactivity, such as open-pit uranium mines, the distribution of ore deposits in underground rock strata is uneven. Therefore, there are significant differences in grade types at different depths in the blast holes. For example, within a single blast hole, there can be abrupt changes in grade type within a few meters or even tens of centimeters.

[0004] Current explosive loading technology relies on lithological data derived from sampling data from a few exploratory boreholes. Based on this data, spatial interpolation or geological inference is performed to generalize the lithological data of all boreholes in the mine. Explosives are then loaded according to this generalized lithological data. Therefore, current explosive loading technology suffers from significant data lag and spatial generalization errors. Summary of the Invention

[0005] In view of the above problems, this application provides a method and related apparatus for loading explosives in radioactive mines to improve the accuracy of explosive loading. The specific solution is as follows:

[0009] The current explosive density of the explosive is adjusted so that the density difference between the current explosive density and the target explosive density is not greater than a preset threshold. During the density adjustment process of the explosive, the current explosive density of the explosive is determined according to the current color signal of the explosive.

[0010] Within each depth range corresponding to each radioactivity level, explosives with adjusted density are loaded.

[0023] According to the preset chromaticity-density calibration curve, the chromaticity value of the explosive is converted into the corresponding density to obtain the current explosive density.

[0024] A second aspect of this application provides an explosive loading system for a radioactive mine, the explosive loading system for the radioactive mine comprising:

[0025] A borehole detection unit is used to acquire borehole layer data in a radioactive mine. The borehole layer data includes at least one radioactivity intensity of the borehole and the depth range corresponding to each radioactivity intensity.

[0026] The data processing unit is used to identify the mineral grade type corresponding to each radioactivity intensity and determine the target explosive density corresponding to the mineral grade type.

[0027] A density adjustment unit is used to adjust the current explosive density of the explosive so that the density difference between the current explosive density and the target explosive density is not greater than a preset threshold. During the density adjustment process of the explosive, the current explosive density is provided by a colorimetric detection unit.

[0028] The colorimetric detection unit is used to determine the current explosive density of the explosive based on the current color signal of the explosive.

[0029] The explosive loading unit is used to load explosives with adjusted density within a depth range corresponding to each radioactivity level.

[0030] In one possible implementation, the borehole detection unit is specifically configured as follows:

Detailed Implementation

[0045] The embodiments of this application are described below with reference to the accompanying drawings. The terminology used in the implementation section of this application is for explaining specific embodiments only and is not intended to limit the scope of this application.

[0046] The embodiments of this application will now be described with reference to the accompanying drawings. Those skilled in the art will recognize that, with technological advancements and the emergence of new scenarios, the technical solutions provided in the embodiments of this application are equally applicable to similar technical problems.

[0047] The terms "first," "second," etc., used in the specification and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate; this is merely a way of distinguishing objects with the same attributes in the embodiments of this application. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, so that a process, method, system, product, or apparatus that comprises a series of units is not necessarily limited to those units, but may include other units not explicitly listed or inherent to those processes, methods, products, or apparatuses.

[0048] Because the mineralization of radioactive elements is essentially a process of fluid transport and instantaneous precipitation, they accumulate only at extremely narrow physicochemical interfaces. Radioactive elements are present in very low and dispersed amounts in ordinary rocks, and must rely on underground fluids (such as groundwater) for dissolution and transport to concentrate and form minerals. When radioactive elements are soluble, they move freely with the liquid; when they are insoluble, they immediately precipitate and accumulate in situ. Furthermore, rock strata are inherently layered, fragmented, and heterogeneous; therefore, the grade of minerals can change abruptly over a very short distance.

[0049] Current explosive loading technology lacks the ability to perceive and respond to the real rock mass inside the borehole in real time. It cannot detect subtle changes in the in-situ rock strata along the depth direction within a single borehole. Therefore, it is impossible to dynamically adjust the explosive loading according to the actual geological conditions.

[0050] Furthermore, since the current explosive loading technology relies on lithological data derived from sampling lithological data from a few exploration holes in the early stages, and spatial interpolation or geological inference is performed based on the lithological data of the sampling lithological data of a few exploration holes to generalize the lithological data of all blast holes in the mine, and explosive loading is carried out according to the generalized lithological data, the current explosive loading technology has obvious data lag and spatial generalization error.

[0051] To address the aforementioned problems, this application provides a method for loading explosives into a radioactive mine. The method for loading explosives into a radioactive mine according to this application will be described in detail below with reference to the accompanying drawings.

[0052] Reference Figure 1 , Figure 1 This application provides a schematic flowchart of a method for loading explosives in a radioactive mine, as illustrated in the embodiments below. Figure 1As shown in the embodiment of this application, a method for loading explosives in a radioactive mine may include steps S10 to S13, which are described in detail below.

[0053] S10. Obtain borehole stratification data in radioactive mines.

[0054] In this context, a radioactive mine can refer to a mining site or area whose primary objective is to extract natural radioactive minerals (such as uranium or thorium). Specifically, in this embodiment, a radioactive mine can be an open-pit uranium mine. A blast hole in a radioactive mine can refer to a hole in the rock mass of the mine used to load explosives during blasting operations.

[0055] Hole stratification data refers to the rock mass data inside the borehole. This rock mass can be divided into waste rock and rock masses of different grades (containing minerals to be mined). Since the mine in this embodiment contains radioactive minerals, and the content of these radioactive minerals varies, their detectable radioactivity intensities differ. Therefore, the hole stratification data in this embodiment can include at least one radioactivity intensity of the borehole, and the depth range corresponding to each radioactivity intensity. Radioactivity intensity can refer to the number of spontaneous decays of radioactive atomic nuclei in a mineral per unit time, and can be used to quantitatively measure the strength of a mineral's radioactivity. In this embodiment, the natural gamma value of the mineral can be used as an indicator to measure the mineral's radioactivity intensity.

[0056] Specifically, in this embodiment, during the movement of the explosive delivery tube within the borehole, the sensor integrated on the explosive delivery tube can be used to collect borehole layer data.

[0057] This embodiment can employ sensors with different functions to collect corresponding data for the boreholes. For example, a radioactivity detection sensor can be used to collect radioactivity data of the boreholes, and a range sensor can be used to collect depth data of the boreholes, forming radioactivity-depth data for the boreholes. The radioactivity detection sensor can be an energy dispersive spectrometer or a miniaturized natural gamma logging probe, which can be integrated into the outer wall of the explosive delivery pipe. The range sensor can be a laser range sensor, or it can employ various range measurement methods such as an encoder mounted on the explosive delivery pipe for range measurement, acoustic range measurement, or suspended weight range measurement.

[0058] Of course, in another alternative embodiment, this embodiment can also use an integrated multi-functional sensor that can simultaneously collect radioactive data and depth data of the borehole to form radioactive-depth data of the borehole. This multi-functional sensor can be integrated into the outer wall of the explosive delivery tube, powered by a built-in battery, and transmits the collected layered data of the borehole wirelessly.

[0059] S11. Identify the mineral grade type corresponding to each radioactivity level and determine the target explosive density corresponding to the mineral grade type;

[0060] S12. Adjust the current explosive density of the explosive so that the density difference between the current explosive density and the target explosive density is not greater than a preset threshold. During the density adjustment process, determine the current explosive density of the explosive based on the current color signal of the explosive.

[0061] Among them, mineral grade type can refer to the category of rocks classified according to the relative content, enrichment degree or industrial utilization value of useful minerals or useful components in the rocks, such as high-grade ore (high mineral content), medium-grade ore (moderate mineral content), low-grade ore (low mineral content) and waste rock (no minerals).

[0062] Because the content of radioactive minerals in a rock mass varies, the intensity of radioactivity in the rock mass also varies. Furthermore, the content of radioactive minerals is related to the mineral grade of the rock mass. Therefore, the intensity of radioactivity in a rock mass can be correlated with the mineral grade of the rock mass, and different intensities of radioactivity can correspond to different mineral grade types.

[0063] This embodiment allows inputting the radioactivity intensity of each layer of borehole data into a preset grade identification model to obtain the mineral grade type output by the model. Specifically, when collecting radioactivity data from boreholes, the collected radioactivity data stream is input into the preset grade identification model, which then outputs the corresponding mineral grade type in real time. The training data for the preset grade identification model can include radioactivity data collected in the target mining area of ​​the radioactive mine, as well as the mineral grade types in the target mining area. The training data can be obtained from historical data of the mine exploration. After training, the preset grade identification model can map the input radioactivity data to the specific mineral grade type of the rock mass.

[0064] This embodiment utilizes a preset grade identification model to convert radioactivity intensity into the corresponding mineral grade type, and can also generate such models in real time. Figure 2 The grade bar chart shown illustrates the mineral grade types corresponding to different depths in the borehole. ppm (parts per million) represents the mineral content, and 1% of a mineral content can be expressed as 10,000 ppm.

[0065] This embodiment utilizes the radioactivity within the borehole to identify the mineral grade type, which not only has high resolution but also strong real-time performance. It realizes a fundamental shift from "loading explosives according to the map (preset map)" to "loading explosives according to the rock (in-situ rock)," and greatly improves the matching accuracy.

[0066] This embodiment, after determining the mineral grade types at different depths within the borehole, can determine the target explosive density for that depth range according to different mineral grade types. Specifically, this embodiment can query the explosive density corresponding to the mineral grade type in a preset knowledge base as the target explosive density. This preset knowledge base can integrate the mechanical properties of different mineral grade types, the theoretical explosive density range determined based on the mechanical properties, the simulated explosive density determined by blasting simulation, and the measured explosive density determined by field tests.

[0067] In this embodiment, the mechanical properties of the rock mass can be determined first based on the mineral grade type. The reasonable range of explosive density (theoretical explosive density range) can be determined by matching the obtained mechanical properties. Within this range, the simulated density value of the blasting simulation and the density value determined by the field test are weighted and fused to obtain the optimal charge density corresponding to the mineral grade type.

[0068] Of course, in another alternative embodiment, this embodiment can also train a grade type-density model based on historical blasting data of mineral grade types, and the model can output the target explosive density at the depth corresponding to the mineral grade type in the blast hole.

[0069] Alternatively, this embodiment can directly determine the target explosive density for different mineral grades based on the wave impedance matching principle or the blasting displacement control principle. The wave impedance matching principle refers to adjusting parameters such as explosive density and detonation velocity to make the wave impedance of the explosive as close as possible to the wave impedance of the blasted medium, thereby maximizing the energy transmission efficiency of the detonation wave, reducing reflection loss, and achieving efficient fragmentation and precise control. For example, for hard, dense rock masses (high wave impedance), high-density, high-detonation-velocity explosives should be used to increase the explosive wave impedance to match the rock mass; for soft or fractured rock masses (low wave impedance), low-density, low-detonation-velocity explosives should be used to avoid excessive rock fragmentation and flyrock. The blasting displacement control principle refers to precisely controlling the displacement of the medium caused by blasting (including throwing, collapse, and sliding) within the expected range by quantitatively designing blasting parameters, optimizing the charge structure and detonation sequence, limiting flyrock, collapse range, and controlling the blast pile shape, achieving directional collapse and contour control (such as slope smoothness), thus meeting the comprehensive control principle of safety and engineering objectives.

[0070] Once the target explosive density at each depth in the borehole is determined in this embodiment, the current explosive density can be adjusted so that the density difference between the current explosive density and the target explosive density does not exceed a preset threshold. This allows the current explosive density to be tracked and stabilized at the target explosive density in real time. The preset threshold can be set based on measured or empirical data. This embodiment can achieve dynamic adjustment of explosive density through a control algorithm. Alternatively, in another optional embodiment, besides adjusting the density based on the density difference between the current and target explosive densities, density adjustment can also be achieved through ratio control (adjusting based on the ratio of the current to the target explosive density), fuzzy control (adjusting according to fuzzy inference rules such as the current explosive density moving away from the target explosive density), and model prediction (the model predicts the next direction of density adjustment based on the current and target explosive densities).

[0071] Specifically, this embodiment can use a PID control algorithm to adjust the explosive density. In this embodiment, the current explosive density and the target explosive density can be input into the PID control algorithm. The PID control algorithm determines the control quantity of the explosive process parameters based on the density difference between the current explosive density and the target explosive density, and generates a control command, which is sent to the subsequent execution unit. The subsequent execution unit adjusts the explosive process parameters according to the control quantity in the control command to adjust the current explosive density.

[0072] The process parameters refer to variables that can be adjusted and controlled, and whose changes can directly or indirectly alter the density state of the explosive. In this embodiment, the sensitizer injection rate or concentration is adjusted to control the sensitizer content in the explosive, thereby adjusting the current explosive density. The sensitizer can be a functional additive that introduces microbubbles or chemically generated gas to form a cavity structure in the explosive matrix. Since the sensitizer can introduce a cavity structure into the explosive, this embodiment can change the cavity structure content in the explosive by changing the amount of sensitizer injected, thereby changing the explosive density and achieving adjustment of the explosive density. Furthermore, during the mixing process of the sensitizer, the sensitizing unit structure (a mixing structure responsible for fully mixing the explosive matrix and the sensitizer, such as an SV-type static mixer) is used to achieve mixing of the explosive matrix and the sensitizer. The longer the sensitizing unit structure, the more shear mixing times the explosive matrix and the sensitizer undergo, resulting in a higher degree of mixing and more complete foaming.

[0073] Furthermore, in the process of adjusting the density of explosives in this embodiment, the current explosive density can be determined at the outlet of the explosive mixer or the outlet of the explosive transfer pipe based on the current color signal of the explosive. Specifically, this embodiment can acquire an image of the explosive under a fixed light source, detect the image color parameters of the image, convert the image color parameters into the chromaticity value of the explosive, and convert the chromaticity value of the explosive into the corresponding density according to a preset chromaticity-density calibration curve to obtain the current explosive density.

[0074] In this embodiment, an industrial vision camera can be used to acquire images of the explosive. During explosive manufacturing, a density-sensitive safety dye can be added to the explosive matrix, and the matrix and dye are then uniformly mixed. Because this embodiment changes the explosive density by altering the volume of the explosive through changes in the content of its cavity structure, it leads to a change in the explosive's color. During the foaming process (injection and mixing of the sensitizer), a higher content of cavity structure in the explosive results in a larger overall volume while maintaining a relatively constant explosive mass. This increases the scattering of light by the internal bubbles, resulting in a lighter explosive color. Therefore, this embodiment can determine the current explosive density by detecting its color.

[0075] To reduce the impact of the environment on the accuracy of color parameters in explosive images, this embodiment selects to acquire explosive images under a fixed light source. Image color parameters refer to the core indicators describing the color attributes, space, and quality of an image, mainly divided into basic color attributes, color space, color quality parameters, and adjustment parameters. Basic color attributes may include hue, saturation, and lightness (or brightness); color space may refer to the color space used by the image (RGB, HSV, etc.); color quality parameters may include color depth, color gamut, white balance, etc.; adjustment parameters may refer to contrast, color temperature, sharpness, exposure, shadows, etc. Specifically, this embodiment mainly identifies the lightness value of the image and converts it into the chromaticity value of the explosive.

[0076] Of course, in another alternative embodiment, in addition to determining the chromaticity value of the explosive by detecting the image as described above, this embodiment can also directly detect and identify the chromaticity value of the explosive by using a color sensor.

[0077] This embodiment uses a preset chromaticity-density calibration curve to convert the acquired chromaticity values ​​of the explosive into its current density. This chromaticity-density calibration curve can be determined through experimental data. By detecting the explosive density and chromaticity values ​​under different sensitizer contents, a mapping relationship between explosive density and chromaticity values ​​is constructed, thus obtaining the chromaticity-density calibration curve. Alternatively, in another optional embodiment, this embodiment can also train a density recognition model using experimental data. The acquired explosive chromaticity values ​​are then input into the trained density recognition model to directly obtain the current explosive density output by the model.

[0078] This embodiment introduces chromaticity as a proxy variable for explosive density. While adjusting the explosive density, it receives the color feedback signal of the explosive to determine the current explosive density. Then, it adjusts the explosive density according to the determined current explosive density, thereby forming a stable and reliable density closed-loop control, which effectively ensures the uniformity and accuracy of explosive loading.

[0079] Furthermore, this embodiment may also include a human-computer interaction and display interface, which can be used to visualize and display data such as borehole radiometric profiles, grade bar charts, target explosive density and actual density explosive curves in the above process in real time.

[0080] S13. Within each depth range corresponding to each radioactivity level, load explosives with adjusted density.

[0081] In this embodiment, during the loading of explosives, explosives can be loaded into the borehole simultaneously with the borehole inspection via an explosives transfer pipe. Specifically, as the explosives transfer pipe moves within the borehole, the embodiment acquires the radioactivity intensity (borehole layer data) at the current depth in real time. Based on the radioactivity intensity at the current depth, it determines the target explosive density required for that depth, automatically adjusts the explosive density, and directly loads the adjusted explosives into the current depth via the explosives transfer pipe.

[0082] Of course, in another optional embodiment, this embodiment can first detect the borehole individually through sensors to obtain the borehole layer data, and then determine the explosive loading scheme in the borehole based on the detected borehole layer data, such as the target explosive density to be filled at each depth of the borehole. Finally, according to the explosive loading scheme, the explosive density is automatically adjusted, and explosives of different densities are automatically loaded into the borehole through the explosive transfer pipe.

[0083] This provides a specific embodiment, such as... Figure 3The explosive loading device shown may include: a loading power unit 100, a processing unit 101, an explosive storage tank 102, an explosive mixing unit 103, a fixing frame 104, an explosive transfer pipe 105, a ranging device 106, a density detection device 107, and a radioactivity detection device 108. This explosive loading device is located above a blast hole in the mine, and the interior of the blast hole can be divided into waste rock 109 and ore 110. Figure 3 This is merely an example to simply illustrate the explosive loading in this embodiment.

[0084] The equipment includes a loading power unit 100, a load-bearing processing unit 101, an explosive storage tank 102, an explosive mixing unit 103, a fixing frame 104, an explosive transfer pipe 105, a ranging device 106, a density detection device 107, and a radioactive detection device 108.

[0085] The mounting bracket 104 can be used to fix the ranging device 106 above the borehole for easy detection of the borehole depth. The processing device 101 can receive the borehole depth data transmitted by the ranging device 106 and the borehole radioactivity intensity data transmitted by the radioactivity detection device 108, determine the borehole depth-radioactivity intensity correlation, determine the mineral grade type of the borehole based on the borehole radioactivity intensity data, and determine the target explosive density corresponding to the borehole as the borehole interior can be divided into waste rock 109 and ore 110.

[0086] The processing device 101 can receive the current explosive density transmitted by the density detection device 107, and control the explosive mixing device 103 to adjust the explosive density according to the current explosive density and the target explosive density. During the density adjustment process, the current explosive density transmitted by the density detection device 107 (which determines the current explosive density through color value detection) can be obtained in real time, thereby determining the direction of explosive density adjustment and the progress of explosive density adjustment.

[0087] After the explosives are adjusted, the processing equipment 101 loads low-density explosives 111 into the depth range of waste rock 109 and high-density explosives 112 into the depth range of ore 110, based on the borehole depth data transmitted by the ranging equipment 106 and the explosives transfer pipe 105. The target explosive densities of the explosives 111 to be loaded into waste rock 109 and the explosives 112 to be loaded into ore 9 are different.

[0088] This application provides a method for loading explosives in a radioactive mine. By identifying the radioactivity intensity in the radioactive mine in real time, the distribution of mineral grade types in the boreholes is determined, thereby further determining the explosive density distribution in the boreholes. This method does not rely on lithological data from a few previous exploration boreholes and does not require spatial generalization, reducing data lag and generalization errors. Furthermore, the current explosive density is determined by combining the current color signal of the explosive. The current explosive density is adjusted in real time based on the target explosive density to achieve dynamic adjustment and control of the explosive density, effectively improving the loading accuracy and blasting effect of the explosives.

[0089] Furthermore, this method determines the explosive density based on the grade type of the rock mass. Through precise matching, it can significantly improve the quality of blasted blocks, reduce the unit consumption of explosives and the base rate, and enhance overall economic benefits.

[0090] The above describes a method for loading explosives in a radioactive mine according to an embodiment of this application. The following will describe a system that applies the above-described method for loading explosives in a radioactive mine.
