Description
Technical Field
[0001] The present application relates to the technical field of construction engineering management, and specifically to a method, device, equipment and storage medium for quantifying energy consumption during the entire mining and selection cycle of metal ore. Background Art
[0002] In the process of mining and beneficiation of metal mineral resources, energy consumption is one of the most important cost expenditure items in the entire operating system. Accurately calculating and evaluating the energy consumption level of the entire mining and beneficiation cycle is of great significance for achieving energy conservation and consumption reduction, improving economic benefits and ensuring sustainable development of mining enterprises.
[0003] The existing technology calculates the energy consumption of the entire mining cycle by determining reasonable blasting parameters. However, when determining blasting parameters, it mainly relies on empirical formulas or simulation tests. The above methods only consider a single factor such as the mining volume or physical property parameters of the target ore when determining blasting parameters, lacking a comprehensive assessment of the specific ore body environment, resulting in inaccurate blasting parameters, which leads to large deviations in the calculated energy consumption of the entire mining cycle of metal ore. Summary of the invention
[0004] The present application provides a method, device, equipment and storage medium for quantifying the energy consumption of a metal ore during the entire mining and selection cycle, which are used to accurately calculate blasting parameters, thereby accurately calculating the energy consumption of a metal ore during the entire mining and selection cycle.
[0005] In the first aspect, the present application provides a method for quantifying energy consumption in the entire mining and selection cycle of metal ore, the method comprising: obtaining the amount of target ore to be mined and the physical property parameters of the target ore; generating initial blasting parameters of the target ore in combination with the amount to be mined, the physical property parameters and the historical mining data of the target ore; adjusting the initial blasting parameters according to the geological conditions, mining process requirements and environmental protection requirements of the target ore, generating target blasting parameters, and calculating a first energy consumption for blasting the target ore under the target blasting parameters; obtaining the crushed size of the target ore obtained after blasting the target ore with the target blasting parameters, and calculating a second energy consumption for grinding the crushed size; arithmetically adding the first energy consumption and the second energy consumption to obtain the total energy consumption of the entire mining and selection cycle of the target ore.
[0006] By adopting the above technical scheme, the method starts with determining the blasting parameters, not only considering the target ore's to-be-mined amount and physical property parameters, but also generating initial blasting parameters in combination with historical mining data. According to the actual geological conditions of the target ore, mining process requirements, environmental protection constraints and other influencing factors, the initial blasting parameters are dynamically adjusted to generate the optimal target blasting parameters that integrate multiple conditions, so that the determined blasting parameters can reflect the actual situation of the ore body to the maximum extent, with high accuracy and pertinence. Based on the actual situation under the optimal blasting parameters, this method quantitatively calculates the energy consumption of the two key links of blasting and grinding, and adds the two to obtain the total energy consumption of the entire mining cycle. The blasting parameters can be accurately calculated, thereby accurately calculating the energy consumption of the entire mining cycle of metal mines. More effectively realize energy saving and consumption reduction in the entire mining process of mines, improve economic benefits and resource utilization efficiency, and promote the green and sustainable development of mines.
[0007] Optionally, the initial blasting parameters of the target ore are generated by combining the amount to be mined, the physical property parameters and the historical mining data of the target ore, including: determining a first blasting parameter of the target ore according to the historical mining data; correcting the first blasting parameter according to the amount to be mined and the physical property parameters to obtain a second blasting parameter; if the second blasting parameter is within a preset blasting parameter range, using the second blasting parameter as the initial blasting parameter; if the second blasting parameter exceeds the preset blasting parameter range, adjusting the second blasting parameter to within the preset blasting parameter range, and using the adjusted blasting parameter as the initial blasting parameter.
[0008] By adopting the above technical solution, the first blasting parameter is first determined based on the historical mining data, and the first blasting parameter is corrected in combination with the amount of target ore to be mined and the physical property parameters to obtain a second blasting parameter that is more in line with the actual situation of the target ore. In order to ensure that the generated initial blasting parameters are within a reasonable and feasible range, the method also introduces a restriction condition of the preset blasting parameter range. If the second blasting parameter is within the range, it is directly used as the initial blasting parameter; if it is out of the range, it is adjusted to within the range to avoid excessively extreme parameter values and ensure the practicality and safety of the parameters.
[0009] Optionally, the physical property parameters include: density, hardness and toughness, and the first blasting parameter is corrected according to the amount to be mined and the physical property parameters to obtain a second blasting parameter, including: calculating the explosiveness index of the target ore according to the density, hardness and toughness, and determining a correction coefficient according to the explosiveness index; arithmetically multiplying the first blasting parameter by the correction coefficient to obtain a third blasting parameter; determining a mining scale coefficient according to the amount to be mined; and arithmetically multiplying the mining scale coefficient by the third blasting parameter to obtain a second blasting parameter.
[0010] By adopting the above technical solution, the method comprehensively considers multiple physical property parameters of the target ore, including density, hardness and toughness, when correcting the first blasting parameter to obtain the second blasting parameter. These parameters have a direct impact on the explosiveness of the ore, so the method first calculates the explosiveness index of the ore based on these parameters, and determines the correction coefficient accordingly. By multiplying the first blasting parameter with the correction coefficient, the intermediate parameter third blasting parameter is obtained. The mining scale coefficient is further determined according to the amount of target ore to be mined, and it is multiplied by the third blasting parameter, and finally the second blasting parameter that fully considers the physical properties of the ore and the mining scale is obtained. It makes up for the deficiency of only considering a single physical property and ignoring the impact of the mining scale. Through the calculation and correction of the above multiple steps, the second blasting parameter finally generated by the method can simultaneously reflect the physical properties of the ore itself and the actual situation of the mining conditions, and has high pertinence and accuracy.
[0011] Optionally, calculating the explosiveness index of the target ore according to the density, hardness and toughness includes: substituting the density, hardness and toughness into a preset formula to calculate the explosiveness index of the target ore; wherein the preset formula is: In the formula, E is the explosiveness index, a, b, c, d are empirical coefficients, ρ is the density, and H is the hardness. T stands for toughness.
[0012] By adopting the above technical solution, the preset formula not only takes into account the inherent physical properties of the ore itself, such as density and hardness, but also introduces toughness, an important parameter that reflects the plasticity of the ore, which can more comprehensively reflect the mechanical response of the ore under blasting. The explosiveness index directly determines the size of the correction coefficient for subsequent calculations, which in turn affects the generation quality of the second blasting parameter. At the same time, the second blasting parameter is an important basis for dynamic adjustment to obtain the target blasting parameter. The accuracy of the blasting parameter is directly related to the actual energy consumption calculation results of the subsequent blasting and grinding. Therefore, this innovative formula provides a scientific and reasonable theoretical basis for the calculation of the explosiveness index, enabling it to reflect the influence of the physical properties of the ore on the blasting with high precision, laying a solid foundation for the precise calculation of each subsequent link, and is a crucial link in the entire technical solution.
[0013] Optionally, the initial blasting parameters include: charge amount, charge structure, blocking length, hole diameter, hole depth, hole spacing, row spacing and ultra-deep hole design, and the initial blasting parameters are adjusted according to the geological conditions, mining process requirements and environmental protection requirements of the target ore to generate target blasting parameters, including: judging whether the initial blasting parameters meet the geological characteristics of the target ore according to the geological conditions of the target ore, if the initial blasting parameters do not meet the geological characteristics of the target ore, adjusting the charge amount, the blocking length, the hole diameter, the hole depth, the hole spacing and the row spacing; judging whether the blasting parameters match the mining process, if they do not match the mining process, adjusting the charge structure and the ultra-deep hole design; judging whether the adjusted initial blasting parameters meet the environmental protection requirements according to the environmental protection requirements, if not, readjusting the charge amount, the hole spacing and the row spacing; and taking the blasting parameters that meet the geological conditions, mining process requirements and environmental protection requirements of the target ore as the target blasting parameters.
[0014] By adopting the above technical scheme, the scheme evaluates the initial blasting parameters according to the actual geological characteristics of the target ore. If the requirements of the geological conditions of the ore body cannot be met, the key parameters such as charge amount, plugging length, hole diameter, hole depth, hole spacing and row spacing are adjusted accordingly to ensure that the blasting design is adapted to the specific geological conditions of the ore body. Secondly, the scheme determines whether the adjusted initial blasting parameters match the actual mining process. If not, the parameters such as charge structure and ultra-deep hole design are further adjusted so that the blasting design can meet the process requirements of the operating system to the greatest extent. In addition, the scheme also fully considers the environmental protection requirements that need to be followed in mining activities. If the adjusted blasting parameters do not meet the environmental protection standards, the parameters such as charge amount, hole spacing and row spacing are further readjusted to meet the constraints of environmental protection regulations. Only when the three basic prerequisites of the above-mentioned target ore body geological conditions, mining process requirements and environmental protection requirements are met at the same time, the scheme determines the dynamically adjusted blasting parameters as the final target blasting parameters. Through the above-mentioned comprehensive dynamic adjustment, the target blasting parameters finally determined by the scheme can reflect the actual situation of the ore body and mining system to a great extent, avoiding the one-sidedness and inapplicability of existing technologies due to lack of comprehensive consideration when determining blasting parameters. Actual blasting operations based on such precise and applicable target blasting parameters can maximize the guarantee that the blasting effect meets expectations, providing a reliable premise for the energy consumption calculation of subsequent key processes.
[0015] Optionally, the calculation of the first energy consumption for blasting the target ore under the target blasting parameters includes: obtaining the charge, hole diameter, hole spacing and row spacing in the target blasting parameters; calculating the mass of explosives required for unit blasting according to the charge, and calculating the total blasting energy consumption according to the mass of explosives required for unit blasting; calculating the drilling volume per unit blasting according to the hole diameter, hole spacing and row spacing, and calculating the total drilling energy consumption according to the drilling volume per unit blasting; arithmetically adding the total blasting energy consumption and the total drilling energy consumption to obtain the first energy consumption for blasting the target ore under the target blasting parameters.
[0016] By adopting the above technical scheme, the scheme extracts the core parameter of charge amount from the target blasting parameters, and accurately calculates the mass of explosives required for unit blasting based on this, and then deduce the total energy consumption of the entire blasting operation. Different from empirical estimation, this calculation method can maximize the reflection of the deterministic relationship between explosive consumption and blasting energy consumption. At the same time, based on the key parameter affecting drilling energy consumption, the scheme extracts data such as hole diameter, hole spacing and row spacing from the target blasting parameters, accurately calculates the drilling volume per unit blasting, and deduce the total energy consumption of the drilling operation in the entire blasting process. Finally, the scheme adds the total blasting energy consumption and the total drilling energy consumption to obtain the first energy consumption of the actual blasting of the ore under the target blasting parameters. This comprehensive energy consumption value not only includes the energy consumption of the blasting operation itself, but also takes into account the energy consumption of the supporting drilling operation. Compared with the existing technology, it can more comprehensively reflect the actual energy consumption of the blasting link, avoid the uncertainty caused by empirical judgment, and improve the reliability and accuracy of the calculation results.
[0017] Optionally, the calculation of the second energy consumption for grinding the broken piece size includes: obtaining the broken piece size distribution of the target ore; calculating the grinding power consumption for grinding the target ore to the target particle size according to the broken piece size distribution; calculating the grinding medium consumption required for grinding the target ore to the target particle size according to the broken piece size distribution, and calculating the grinding medium energy consumption according to the grinding medium consumption; adding the grinding power consumption and the grinding medium energy consumption to obtain the second energy consumption for grinding the broken piece size.
[0018] By adopting the above technical scheme, the scheme obtains the distribution data of the broken fragmentation after the actual blasting of the ore. The broken fragmentation directly determines the power consumption required for subsequent grinding and is the fundamental factor affecting the grinding energy consumption. Carrying out subsequent energy consumption calculations based on this can maximize the reflection of the actual condition of the ore and avoid the deviation of the results based on subjective estimates or standard assumptions. Secondly, based on the broken fragmentation distribution, the scheme models and calculates the power consumption required to grind the ore to the target particle size. This step quantifies the deterministic relationship between the broken fragmentation distribution and the power consumption, eliminating the uncertainty influence of subjective estimates. At the same time, the scheme also calculates the amount of grinding media required to grind to the target particle size under the above-mentioned broken fragmentation distribution conditions, and further calculates the corresponding energy consumption. As an important input in the grinding process, the consumption of grinding media directly affects the overall energy consumption level, and its quantitative calculation reflects innovation. Finally, the scheme adds the calculated grinding power consumption and grinding media energy consumption to obtain a complete second energy consumption result. Compared with simply calculating power consumption or estimating the impact of grinding media, this solution more comprehensively integrates the two main factors affecting grinding energy consumption and can more accurately reflect the actual situation.
[0019] In a second aspect, the present application provides a device for quantifying energy consumption in the whole cycle of metal ore mining and dressing, the device comprising: an acquisition module, a combination module, a first calculation module, a second calculation module and an output module; wherein the acquisition module is used to acquire the amount of target ore to be mined and the physical property parameters of the target ore; the combination module is used to combine the amount to be mined, the physical property parameters and the historical mining data of the target ore to generate the initial blasting parameters of the target ore; the first calculation module is used to adjust the initial blasting parameters according to the geological conditions, mining process requirements and environmental protection requirements of the target ore, generate target blasting parameters, and calculate the first energy consumption of blasting the target ore under the target blasting parameters; the second calculation module is used to acquire the crushed size of the target ore obtained after blasting the target ore with the target blasting parameters, and calculate the second energy consumption of grinding the crushed size; the output module is used to arithmetically add the first energy consumption and the second energy consumption to obtain the total energy consumption of the whole cycle of mining and dressing of the target ore.
[0020] In the third aspect, the present application provides an electronic device, which adopts the following technical solution: it includes a processor, a memory, a user interface and a network interface, the memory is used to store instructions, the user interface and the network interface are used to communicate with other devices, and the processor is used to execute the instructions stored in the memory so that the electronic device executes a computer program such as any of the above-mentioned methods for quantifying energy consumption in the entire cycle of metal mining and selection.
[0021] In a fourth aspect, the present application provides a computer-readable storage medium, which adopts the following technical solution: storing a computer program that can be loaded by a processor and execute any of the above-mentioned methods for quantifying energy consumption in the entire cycle of metal mining and selection.
[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. This method starts with determining the blasting parameters. It not only considers the target ore's to-be-mined volume and physical property parameters, but also generates initial blasting parameters in combination with historical mining data. According to the actual geological conditions of the target ore, mining process requirements, environmental protection constraints and other influencing factors, the initial blasting parameters are dynamically adjusted to generate the optimal target blasting parameters that integrate multiple conditions, so that the determined blasting parameters can reflect the actual situation of the ore body to the maximum extent, with high accuracy and pertinence. Based on the actual situation under the optimal blasting parameters, this method quantitatively calculates the energy consumption of the two key links of blasting and grinding, and adds the two to obtain the total energy consumption of the entire mining cycle. The blasting parameters can be accurately calculated, thereby accurately calculating the energy consumption of the entire mining cycle of metal ores. More effectively realize energy saving and consumption reduction in the entire mining process of mines, improve economic benefits and resource utilization efficiency, and promote the green and sustainable development of mines.

[0025] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments.
[0026] In the description of the embodiments of the present application, words such as "illustrative", "for example" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "illustrative", "for example" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs.

[0027] Figure 1 Schematic diagram of a method for quantifying energy consumption in the whole cycle of metal mining and selection provided in the embodiment of the present application. Figure 1 As shown, the method includes S101-S105: S101, obtaining the amount of target ore to be mined and the physical property parameters of the target ore.
[0028] In one example, the amount of ore to be mined refers to the total amount of ore that needs to be mined, usually in tons. This data usually comes from geological exploration and reserve estimation, reflecting the scale of mining. Physical property parameters include the density, hardness and toughness of the ore, which describe the physical characteristics of the ore and are crucial for formulating reasonable blasting and crushing plans.
[0029] These parameters are usually obtained through field surveys and sampling tests of the mining area. The amount to be mined can be estimated through drilling, geophysical exploration and other means; while physical property parameters need to be measured from ore samples, such as hardness with a penetrometer, toughness with a tearing instrument, and density with water precipitation.
[0030] S102, generating initial blasting parameters of the target ore in combination with the amount to be mined, physical property parameters and historical mining data of the target ore.
[0031] In one example, after obtaining the target ore's to-be-mined volume, physical property parameters, and historical mining data, the initial blasting parameters are generated based on this information. The purpose of this step is to preliminarily determine a set of reasonable blasting parameters based on the actual conditions of the ore, in preparation for subsequent adjustment and optimization.
[0032] Specifically, firstly, the first blasting parameters used in the previous blasting of the ore are obtained from the historical mining data. These historical data have accumulated the previous mining experience of the mine and can be used as a reference for the initial blasting parameters.
[0033] Then, according to the amount to be mined and the physical properties of the target ore (density, hardness, toughness), the first blasting parameter is corrected to obtain the second blasting parameter. The basis for the correction is that the amount to be mined determines the scale of mining, and different scales require adjustment of the blasting design; while the physical properties of the ore affect its explosiveness, and the blasting parameters such as charge amount and aperture need to be adjusted accordingly. During the correction, an explosiveness index and a corresponding correction coefficient will also be calculated.
[0034] Next, compare the second blasting parameter with the preset reasonable blasting parameter range. If it is within the range, the second blasting parameter is the initial blasting parameter; if it is out of the range, the second blasting parameter needs to be adjusted to within the range, and the adjusted parameter is used as the initial blasting parameter. Control the blasting parameters within a reasonable range to avoid extreme situations.
[0035] Based on the above embodiment, as an optional implementation, in S102, combining the amount to be mined, physical property parameters and historical mining data of the target ore, generating the initial blasting parameters of the target ore specifically includes S21-S24: S21, determining the first blasting parameters of the target ore according to historical mining data.
[0036] In one example, during the long-term mining of the same ore body, a mine will accumulate a large amount of blasting operation data, such as the previously used blasting parameters such as charge amount, hole diameter, plugging length, row spacing, and corresponding blasting effect feedback.
[0037] Therefore, when generating the initial blasting parameters, the blasting parameters previously used for the ore can be directly retrieved from the historical mining database and regarded as the first blasting parameters.
[0038] Although the previous blasting parameters were reasonable, they cannot be directly adopted in their entirety because the specific scale of this mining, ore properties, etc. may be different from before. They also need to be appropriately adjusted and optimized based on the new conditions.
[0039] S22, modifying the first blasting parameter according to the amount to be mined and the physical property parameter to obtain a second blasting parameter.
[0040] In one example, the volume to be mined reflects the scale of mining and is closely related to the blasting design. When the volume to be mined is significantly different from the historical situation, the original blasting parameters may not be applicable. For example, if the volume to be mined increases significantly, the charge, hole spacing, and row spacing need to be appropriately increased to ensure sufficient blasting energy and loose ore volume; vice versa.
[0041] Secondly, it is necessary to consider the influence of the physical properties of the ore, mainly including the density, hardness and toughness of the ore. These properties determine the explosive characteristics and the difficulty of crushing the ore. For example, for high-density hard ores, it is necessary to increase the charge per unit volume and reduce the hole spacing and row spacing to increase the blasting kinetic energy; while for ores with higher toughness, it is necessary to increase the charge, hole depth and plugging length to increase the penetration depth and impact energy.
[0042] Based on the above factors, an explosiveness index can be calculated first to reflect the overall explosiveness of the ore. Then, according to the explosiveness index and the amount to be mined, the first blasting parameter is quantitatively corrected to obtain the second blasting parameter. During the correction, some correction coefficients are usually introduced to adjust the parameters to a more reasonable range.
[0043] The second blasting parameters have taken into account the specific conditions of this mining operation, and are more in line with the actual situation than the first blasting parameters, which is conducive to further optimization and generation of the final target blasting parameters. At the same time, the introduction of the explosiveness index as a quantitative indicator also makes the adjustment of blasting parameters more scientific and standardized.
[0044] Based on the above embodiment, as an optional implementation, in S22, the physical property parameters include: density, hardness and toughness. According to the amount to be mined and the physical property parameters, the first blasting parameters are corrected to obtain the second blasting parameters, which specifically include S221-S224: S221, calculating the explosiveness index of the target ore according to the density, hardness and toughness, and determining the correction factor according to the explosiveness index.
[0045] In one example, the density, hardness and toughness are substituted into a preset formula to calculate the explosiveness index of the target ore; wherein the preset formula is: In the formula, E is the explosiveness index, a, b, c, d are empirical coefficients, ρ is the density, and H is the hardness. T stands for toughness.
[0046] This item mainly reflects the influence of ore density and hardness on explosiveness. 2 It represents the quadratic term of density. This is because the greater the density, the stronger the ore agglomeration, which hinders the blasting effect. Therefore, the influence of density should be nonlinear.
[0047] The influence of density is controlled by the empirical coefficient a, (b+H) is the denominator, H is the hardness, the higher the hardness, the harder it is to break the ore, and the worse the explosiveness. b is a constant term to avoid the denominator being zero.
[0048] This term represents the effect of toughness on explosiveness. The square root form of toughness T reflects that the effect of toughness is a slowly increasing rather than a linear relationship, and the coefficient c controls the weight of toughness.
[0049] This term reflects the interactive effect of density and hardness. d is the empirical coefficient, which controls the weight of the interaction term and reflects the interactive effect of density and hardness on explosiveness.
[0050] The formula combines three key physical parameters, density, hardness, and toughness, and expresses their effects on explosiveness using single, double, and triple interaction terms. Density has the greatest impact, and its nonlinear relationship is reflected by the quadratic term. Hardness is second, and the denominator reflects that the greater the hardness, the worse the explosiveness. Toughness has a smaller impact, and the square root term represents a slow increase. The interaction between density and hardness is also taken into account.
[0051] The empirical coefficients a, b, c, and d in each item need to be obtained by fitting historical data, which enables the formula to more accurately reflect the conditions of different types of ores. This formula comprehensively considers the main influencing factors, helps to reasonably evaluate the explosive characteristics of the ore, and provides a basis for the subsequent determination of blasting parameters.
[0052] S222, arithmetically multiplying the first blasting parameter by the correction coefficient to obtain a third blasting parameter.
[0053] In one example, the first blasting parameter is obtained based on the historical mining data of the ore. Although it has a certain rationality basis, it may have some deviations from the actual situation of the target ore. The previously calculated explosiveness index has quantitatively reflected the comprehensive influence of the key physical properties of the ore, such as density, hardness, and toughness, on its explosive characteristics. By mapping this index to a correction coefficient, the degree to which the first blasting parameter needs to be adjusted can be quantitatively described.
[0054] Next, it is only necessary to perform simple arithmetic multiplication of the correction coefficient with each sub-parameter in the first blasting parameter, such as charge, hole spacing, row spacing, plugging length, etc., to obtain the corresponding third blasting parameter. For example, if the correction coefficient is 1.2, then the charge needs to be multiplied by 1.2 to increase; if the correction coefficient is 0.8, the row spacing needs to be multiplied by 0.8 to decrease, and so on.
[0055] This simple multiplication adjustment operation is actually based on the first blasting parameter, and it is proportionally enlarged or reduced according to the difference in ore explosiveness. Through this step, the third blasting parameter not only inherits the reasonable part of the first blasting parameter that adopts historical experience, but also integrates the influence of the physical properties of the ore, so that the setting of the blasting parameter is more accurate and reasonable.
[0056] S223, determining the mining scale coefficient according to the amount to be mined.
[0057] In one example, through historical data analysis, the empirical relationship between the amount to be mined and the optimal blasting parameters actually adopted is fitted into a piecewise function or a lookup table, wherein the magnitude of the amount to be mined is divided into several intervals, each of which corresponds to a range of values of the mining scale coefficient.
[0058] Next, substitute the value of the current volume to be mined into the above function or table to query, and you can get the corresponding mining scale coefficient value. The coefficient value is generally set to a decimal in the range of 0-2. A value greater than 1 indicates an enlarged coefficient of the blasting parameters, and a value less than 1 indicates a reduced coefficient.
[0059] Finally, the fourth blasting parameter after scale adjustment can be obtained by multiplying the obtained mining scale coefficient with each sub-parameter in the third blasting parameter.
[0060] Through this adjustment, the fourth blasting parameter not only takes into account the physical properties of the ore and historical experience, but also fully integrates the important influencing factor of mining scale, making the parameter setting closer to the actual mining conditions. When further adjustments are made based on other influencing factors, they will also be more targeted on this basis.
[0061] It should be noted that the fitting function or lookup table in the above method needs to be modeled or adjusted accordingly according to the actual conditions of different mineral types and regions. The accuracy of the function or table will gradually improve through the continuous accumulation of engineering practice data and continuous improvement.
[0062] S224, arithmetically multiplying the mining scale coefficient by the third blasting parameter to obtain a second blasting parameter.
[0063] S23: If the second blasting parameter is within the preset blasting parameter range, the second blasting parameter is used as the initial blasting parameter.
[0064] S24: If the second blasting parameter exceeds the preset blasting parameter range, the second blasting parameter is adjusted to be within the preset blasting parameter range, and the adjusted blasting parameter is used as the initial blasting parameter.
[0065] In one example, it is necessary to first set the reasonable value range of each blasting parameter in advance, such as the upper and lower limits of charge amount, hole spacing, row spacing, etc. The setting of these ranges is usually based on theoretical calculations, experience accumulation, and relevant regulations and standards.
[0066] Next, the parameter values in the second blasting parameters are compared with the preset range one by one. If any parameter exceeds the range, it is necessary to adjust the parameter so that it falls within the range. The adjustment can be made by interpolation, taking the closest value, etc.
[0067] If multiple parameters are out of range at the same time, it is necessary to adjust the key parameters that have a greater impact on the blasting effect based on the importance and influence weight of each parameter, and adjust the secondary parameters based on meeting the range. During the adjustment process, it is also necessary to pay attention to the relationship and constraints between the parameters to avoid causing new out-of-range problems.
[0068] After the above adjustment, the blasting parameter combination obtained is the initial blasting parameter. Compared with directly adopting the second blasting parameter, the initial blasting parameter is more reasonable and controllable, with less risk and more reliable implementation.
[0069] Of course, the initial blasting parameters may still not match the geological conditions, process requirements or environmental requirements. Therefore, the initial blasting parameters will need to be further adjusted based on these factors to obtain the target blasting parameters that truly meet all requirements.
[0070] S103, adjusting initial blasting parameters according to geological conditions, mining process requirements and environmental protection requirements of the target ore, generating target blasting parameters, and calculating a first energy consumption for blasting the target ore under the target blasting parameters.
[0071] In one example, it is necessary to first determine whether the initial blasting parameters meet the geological characteristics of the ore. If not, it is necessary to adjust the charge, plugging length, hole diameter, hole depth, hole spacing, and row spacing. Because different geological conditions have different requirements for blasting design, only by matching the specific situation can the blasting achieve the expected effect.
[0072] Secondly, determine whether the blasting parameters are consistent with the selected mining process. If they do not match, it is necessary to adjust the charge structure and ultra-deep hole design. Different mining processes will have different requirements for blasting fragmentation, safety, etc., and the blasting parameters need to be coordinated with them.
[0073] Thirdly, according to environmental protection requirements, determine whether the adjusted blasting parameters can meet environmental protection standards. If not, it is necessary to readjust the charge, hole spacing and row spacing to control blasting vibration, noise and dust within the allowable range.
[0074] After the above repeated judgments and adjustments, the blasting parameters finally generated will be the optimal blasting plan that comprehensively considers various factors such as geology, technology and environmental protection, and are called target blasting parameters.
[0075] After determining the target blasting parameters, the first energy consumption required for blasting under the parameters can be further calculated. Specifically, the mass of explosives required for unit blasting and the total blasting energy consumption are calculated based on the charge amount; the unit drilling volume and the total drilling energy consumption are calculated based on the hole diameter, hole spacing and row spacing; the sum of the two is the first energy consumption.
[0076] Based on the above embodiment, as an optional implementation mode, in S103, the initial blasting parameters include: charge amount, charge structure, plugging length, hole diameter, hole depth, hole spacing, row spacing and ultra-deep hole design. According to the geological conditions of the target ore, mining process requirements and environmental protection requirements, the initial blasting parameters are adjusted, and the target blasting parameters are generated, which specifically include S301-S304: S301, judging whether the initial blasting parameters meet the geological characteristics of the target ore according to the geological conditions of the target ore, if the initial blasting parameters do not meet the geological characteristics of the target ore, adjusting the charge amount, plugging length, hole diameter, hole depth, hole spacing and row spacing.
[0077] In one example, when judging whether the fourth blasting parameter meets the geological characteristics of the target ore, the main geological factors that need to be considered include: the structural structure of the ore, the distribution of lithology, the development of fissures, the properties of the surrounding rock, etc. For example, if the target ore is a blocky structure with developed joints and fissures, then the charge and plugging length in the blasting parameters need to be appropriately increased to ensure that the blasting energy can be effectively transmitted to the interior of the ore; at the same time, the hole spacing and row spacing also need to be reduced to improve the blasting efficiency per unit area. If the surrounding rock is relatively hard, it is necessary to increase the hole diameter and hole depth, and appropriately increase the charge to provide sufficient energy to break through the resistance of the surrounding rock.
[0078] If it is determined that the fourth blasting parameter does not match the ore geological conditions, then the relevant parameters need to be adjusted in a targeted manner. Specifically, based on the above judgment basis, the parameters that may need to be adjusted include: charge amount, plugging length, hole diameter, hole depth, hole spacing and row spacing, etc. The adjustment method can be simply multiplied by a coefficient to enlarge or reduce, or it can be mapped and corrected by consulting a fitting function or an empirical table.
[0079] Through the adjustment of this step, the fifth blasting parameter not only inherits the rationality of the previous step in considering factors such as ore physical properties and mining scale, but also incorporates the key influencing factor of ore geological conditions. As a result, the final blasting parameters can best fit the actual situation of the target ore, which is conducive to achieving efficient, safe and economical mining operations.
[0080] S302, determining whether the blasting parameters match the mining process; if not, adjusting the charge structure and ultra-deep hole design.
[0081] In one example, when judging whether the blasting parameters match the mining process, it is necessary to focus on key aspects of the mining process, such as the operation mode, stope layout, support method, and transportation method. For example, for the open-pit mining process, the blasting parameters need to focus on the blasting effect in the plane, and the charging structure can adopt a short borehole dense charging; while for the chute return loading process, it is necessary to focus on the blasting effect in the vertical direction, and the ultra-deep hole design will be the key. In addition, when the stope is narrow, the blasting parameters also need to reduce the vibration radiation radius; when mechanical and manual support methods are used, the requirements for impact resistance are also different.
[0082] If it is determined that the fifth blasting parameter does not match the actual mining process, then the charge structure and ultra-deep hole design need to be adjusted accordingly. For the charge structure, it can be optimized by changing the charge mode, charge length, detonation network and other contents; for the ultra-deep hole design, it is necessary to consider adjusting the hole depth, offset hole angle, offset hole length and other parameters. When making adjustments, it is necessary to combine the process characteristics and the expected blasting effect, and make scientific calculations and empirical corrections to the above contents.
[0083] S303, judging whether the adjusted initial blasting parameters meet the environmental protection requirements according to the environmental protection requirements, and if not, readjusting the charge amount, hole spacing and row spacing.
[0084] In one example, after the previous adjustments, the blasting parameters can better meet the characteristics of the ore itself and the mining process requirements, but it is still necessary to further determine whether these parameters meet the relevant requirements of environmental protection laws and regulations. If there is a non-compliance, key parameters such as charge amount, hole spacing and row spacing need to be readjusted to meet environmental compliance standards. The necessity of this step lies in the fact that modern mining needs to attach great importance to ecological and environmental protection, and reasonably control the adverse effects of noise vibration, dust flying, rock dispersion, etc. during the blasting process to minimize the impact on the environment. Only by fully considering environmental factors can the design of blasting parameters be truly scientific and reasonable.
[0085] When judging whether the adjusted blasting parameters meet environmental protection requirements, it is necessary to focus on the main influencing indicators such as blasting vibration, flying rocks, and dust. For example, according to the environmental functional zoning and relevant regulations and standards of the area, the peak value of blasting vibration must be controlled within a certain range; the range of flying rocks must be limited within the safety protection range; and the dust emission concentration must not exceed the specified threshold. Each of these indicators has a strict judgment formula and calculation method.
[0086] If it is found that some of the blasting parameters, such as charge, hole spacing, and row spacing, do not meet the above environmental protection index requirements, then these parameters need to be readjusted. The basic idea of adjustment is: increasing the charge will usually increase the impact of vibration and flying stones, so it needs to be appropriately reduced; and when the hole spacing and row spacing are set densely, although it can improve the blasting efficiency, it will also have a greater impact on dust and vibration, so it is necessary to determine whether to increase it based on the specific situation. During the adjustment process, relevant empirical formulas or numerical simulations can be used to predict the environmental impact of the proposed adjustment plan, and compared with the standard threshold value to determine a reasonable parameter combination.
[0087] Through this adjustment, the blasting parameters not only meet the ore characteristics and mining process, but also meet the requirements of environmental protection regulations, truly achieving safety, efficiency and environmental protection. Reasonable control of the impact of blasting environment is conducive to maintaining the ecological environment of the mining area and neighboring areas, and establishing a green and environmentally friendly mine image.
[0088] S304, taking blasting parameters that meet the geological conditions, mining process requirements and environmental protection requirements of the target ore as target blasting parameters.
[0089] Based on the above embodiment, as an optional implementation, in S103, calculating the first energy consumption for blasting the target ore under the target blasting parameters specifically includes performing S401-S404: S401, obtaining the target blasting parameters including charge amount, hole diameter, hole spacing and row spacing.
[0090] S402, calculating the mass of explosives required for a unit blast according to the charge amount, and calculating the total energy consumption of the blast according to the mass of explosives required for the unit blast.
[0091] In one example, firstly, the mass of explosives required in each blasthole is calculated based on the designed charge parameters and the volume of a single blasthole; then the mass of explosives per hole is multiplied by the total number of blastholes in the unit blasting area to obtain the total amount of explosives used in the unit area. The calculation formula for the mass of explosives per hole is: The mass of explosives per hole = charge density × charge volume, where the charge volume is determined by the hole diameter and charge length. The total number of blastholes per unit area is calculated from hole spacing, row spacing and other hole layout parameters.
[0092] After knowing the amount of explosives used per unit blasting area, we need to add it to the entire blasting operation to get the total mass of explosives required for the entire operation. Then we multiply the mass of explosives by the energy equivalent of unit mass of explosives to calculate the total energy consumption of the entire operation.
[0093] S403, calculating the drilling volume per unit blasting according to the hole diameter, hole spacing and row spacing, and calculating the total drilling energy consumption according to the drilling volume per unit blasting.
[0094] In one example, the volume of a single borehole is first calculated based on the designed aperture parameters; then the single borehole volume is multiplied by the total number of boreholes in the unit area to obtain the total borehole volume of the area. The calculation formula for the single borehole volume is: single borehole volume = π × (aperture / 2) 2 × hole depth, the total number of holes drilled per unit area is determined by hole spacing, row spacing and other hole layout parameters.
[0095] After knowing the total drilling volume per unit area, the next step is to add up the volumes of each unit area to get the total drilling volume within the entire blasting operation range. Then multiply this total volume by the energy consumption equivalent of drilling per unit volume to calculate the total drilling energy consumption for the entire operation.
[0096] After calculating the total energy consumption of drilling, it can be evaluated together with the previously calculated blasting energy consumption, so as to fully control the energy cost of the entire blasting operation system. If the drilling energy consumption is too high, you can consider appropriately increasing the hole spacing to reduce the drilling workload; adopt new high-efficiency drilling rigs and other measures to reduce unit energy consumption. Through real-time monitoring and continuous optimization of the energy consumption of the two key links of drilling and blasting, the total energy consumption and total cost expenditure of the entire system can be saved to the maximum extent.
[0097] S404, arithmetically adding the total blasting energy consumption to the total drilling energy consumption to obtain a first energy consumption for blasting the target ore under the target blasting parameters.
[0098] S104, obtaining the crushed size of the target ore after blasting the target ore using the target blasting parameters, and calculating the second energy consumption of grinding the crushed size.
[0099] In one example, after the target blasting parameters are determined and the first energy consumption is calculated, the ore is blasted using the target blasting parameters to obtain the distribution of broken ore fragmentation, and based on this, the second energy consumption required to grind the broken ores to the target particle size is calculated.
[0100] This step is necessary because blasting is the first process in mining, and the particle size distribution of the crushed ore directly affects the subsequent grinding process. Different crushed pieces require different levels of grinding energy consumption to achieve the particle size requirements required for ore dressing. Therefore, knowing the crushed piece size distribution after blasting is crucial for evaluating and optimizing the energy consumption of the grinding process.
[0101] Specifically, it is first necessary to carry out actual blasting operations on the ore under the target blasting parameters, and then measure and count the distribution of broken pieces of the ore after blasting through screening and other methods, including the proportion of ore of each particle size level.
[0102] Next, based on the obtained fragmentation distribution, the energy consumption required to grind the crushed ores to the set target particle size can be calculated. It usually includes the following two parts: Grinding power consumption: According to the fragmentation distribution, combined with the grinding equipment and process parameters, the power consumption required to grind the ore to the target particle size is calculated. Grinding medium energy consumption: According to the fragmentation distribution, the amount of grinding medium (such as steel balls) required to be added is calculated, and then the total grinding medium energy consumption is calculated based on the unit energy consumption of the medium.
[0103] By adding the above two energy consumptions, the second energy consumption required to grind the broken ore to the target particle size can be obtained.
[0104] Based on the above embodiment, as an optional implementation, in S104, the second energy consumption of grinding the crushed piece size specifically includes S501-S504: S501, obtaining the fragmentation distribution of the target ore.
[0105] S502, calculating the grinding power consumption for grinding the target ore to the target particle size according to the crushing size distribution.
[0106] In one example, to calculate the power consumption of grinding, it is first necessary to predict the distribution of block size after blasting based on the blasting parameters and ore properties, and obtain the mass fraction of each particle size segment. Next, substitute these fractions into the empirical formula of the actual factory or consult the corresponding energy consumption table to calculate the unit energy consumption required to grind to the target particle size. Finally, multiply the unit energy consumption by the total amount of ore to be ground to get the total power consumption of grinding. In some complex cases, it can also be solved with the help of historical data fitting and other means. Through this series of calculations, the energy consumption level of the grinding process can be known more accurately.
[0107] After obtaining the estimated grinding power consumption, if it is found that the power consumption is too high, you can consider adjusting the blasting parameters appropriately to optimize the block size distribution and increase the proportion of larger particle size segments, thereby reducing the grinding energy consumption. At the same time, you can also evaluate the feasibility of using new and efficient grinding equipment to further reduce unit energy consumption. Through the coordinated optimization of the previous and next processes, precise control can be achieved at both ends of blasting and mineral processing, which can ultimately significantly save the total energy consumption and total cost of the entire system.
[0108] It should be noted that in actual projects, there are usually certain cross-effects and influences in the blasting, crushing and grinding links. Therefore, the coupling effect of each link needs to be considered during calculation to avoid repeated calculation or omission of energy consumption. In addition, in addition to power consumption, the consumption of other mineral processing materials such as grinding media and reagents also needs to be evaluated and calculated together to more comprehensively reflect the overall cost status of the mineral processing process.
[0109] S503, calculating the grinding medium consumption required to grind the target ore to the target particle size according to the crushing size distribution, and calculating the grinding medium energy consumption according to the grinding medium consumption.
[0110] In one example, firstly, based on the known distribution of crushed fragments, the unit medium consumption required for grinding to the target particle size is estimated by using the empirical formula of the actual factory or referring to the corresponding parameter manual; then the unit consumption is multiplied by the total amount of ore to be ground to obtain the total medium consumption in the grinding process. Among them, the main factors affecting the unit medium consumption include the hardness of the ore, the target particle size, the type of grinding media, etc.
[0111] After knowing the total media consumption, the next step is to convert it into the corresponding energy consumption, that is, the grinding media energy consumption. The calculation method is to multiply the total consumption by the production energy consumption equivalent per unit of media. The specific value of the production energy consumption equivalent can usually be obtained by referring to the parameter information provided by the media supplier.
[0112] After calculating the energy consumption of the grinding media, you can evaluate it together with the previously calculated power consumption to fully control the total energy consumption level of the grinding process. If the overall energy consumption is found to be too high, you can consider adjusting the parameters appropriately in the blasting process to optimize the block size distribution and improve the medium utilization efficiency; or evaluate the feasibility of using new and efficient grinding media to reduce unit consumption. At the same time, you can also evaluate the recycling method to maximize the service life of the media, thereby reducing new investment. Through the coordinated optimization of the previous and next processes, comprehensive energy conservation and emission reduction can be achieved in all links of blasting, crushing and mineral processing.
[0113] It should be noted that in the calculation process, in addition to considering the medium consumption of grinding itself, the energy consumption of other auxiliary links such as transportation, loading and unloading of the medium must also be included. In addition, other energy consumption that may be generated during the production and recycling of the medium also needs to be included in the overall assessment. Only by calculating and summing up the energy consumption of each link one by one can the comprehensive energy consumption level of the grinding medium throughout its life cycle be truly reflected.
