The blast data comprised 125 datasets, each containing seven blast design parameters as inputs and the muckpile mean fragment size as the model output. Additionally, the study developed artificial neural networks (ANNs), support vector regression (SVR), and multiple linear regression (MLR) models, and compared their prediction performances with the GPR model. The models’ accuracies were evaluated using five statistical metrics, including coefficient of determination (<span>({R}^{2})</span>), root mean square error (RMSE), variance accounted for (VAF), mean absolute bias error (MABE), and mean absolute percentage error (MAPE). The GPR model outperformed the other models, with <span>({R}^{2})</span>, RMSE, VAF, MABE, and MAPE values of 0.9302, 0.0487, 93.2670, 0.0383, and 13.9405, respectively, for the test data. Based on the top-down correlation and Kendall’s coefficient of concordance analyses on the four sensitivity analysis methods used, the study found that the in situ block size and Young’s modulus of the rock were the most important parameters affecting fragmentation. Using the GPR model, the study showed that reducing the blast burden by 13–23% could decrease the mean fragment size of the muckpile at Wolongan Mine by 6–12%, leading to a significant reduction in the percentage of boulders.</p>","PeriodicalId":18588,"journal":{"name":"Mining, Metallurgy & Exploration","volume":"38 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142183137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prior research has acknowledged that strategies for mine planning and the design of mineral concentrators are interdependent; thus, it is highly desirable to optimize them together. However, achieving detailed holistic optimization of the entire mineral value chain remains unresolved because of the inherent limitations associated with mathematical formulations and computational processing capacity. This paper details a method that contributes to bridging these limitations by employing a novel parallelized variable neighborhood descent approach combined with an embedded mass–balance component using linear programming techniques refined through Dantzig–Wolfe decomposition.

These deposits are also accompanied by deposits of low- to high uranium grade. In addition to Zn, Pb, and Cu anomalies, particularly in fault zones and their branches affecting the study area, although there are numerous zinc minerals in the Ocher-Greifat area, uranium minerals are scarce, with only one mineral, compreignacite, being recorded and the majority of the uranium being present as an adsorbed element on iron and/or clay stones. In addition, uranothorite is extremely rare and occurs as fine grains embedded in rocks. A technological sample was taken from an iron-rich clay area in a fault zone and was found to assay 700-ppm uranium. The leachability of uranium from the used sample was investigated using an alkaline solution based on the chemical and mineralogical composition of the used sample. The selected ore is treated with Na<sub>2</sub>CO<sub>3</sub> and NaHCO<sub>3</sub> in the presence of H<sub>2</sub>O<sub>2</sub> as oxidant. Many digestion factors are studied and optimized.

The system was subject to many of the common challenges preventing the widespread use of underground spot cooling, including limited process water and dewatering capability, heat rejection equipment placement in the path of blasting fumes, limited airflow quantity for heat rejection, and layout constraints due to the existing and upcoming mine services installations and construction. Use of hybrid cooling towers allowed for increased heat rejection capacity from evaporative cooling while maintaining a fully closed-loop condenser water circuit.

Boulders or large fragments can result in more costs because they need secondary blasting, while small fragments can result in ore loss and dilution. Therefore, it is very significant to accurately predict the mean block size to reduce production costs and enhance efficiency. Due to the shortfalls of the empirical models, scholars have been inclined toward artificial intelligence (AI) techniques for fragmentation size prediction over the decades. Firstly, in this study, three tree-based models, i.e., the random forest (RF), extra-trees (ET), and CatBoost (CB), are employed for basic prediction. The model uses eight parameters, seven input parameters, and mean block size (MBS) as the output parameter. Secondly, their performance and hyper-parameters were fine-tuned using Bayesian optimization: tree-structured Parzen estimators (TPE) algorithm using Optuna. Among the three models, the TPE-ET model showed superior performance with the following metric scores on the training dataset: 0.9896, 0.0184, and 0.0003, and on the test dataset with the following metric scores: 0.9463, 0.0415, and 0.0017, i.e., <i>R</i><sup>2</sup>, RMSE, and MSE, respectively.

Therefore, this research aims to develop a hybrid model that combines fuzzy analytical hierarchy process (FAHP) with multi-attribute utility theory (MAUT) to help decision-makers achieve optimal results when faced with diverse investment opportunities and criteria. The study uses data from a private consulting firm. The report consists of 225 projects and 16 attributes. The statistical analysis was performed through SPSS, involving a <i>t</i>-test, one-way ANOVA, Pearson correlation, and regression analysis. FAHP and MAUT were performed via python programming and a sensitivity analysis was conducted to verify the validity of the data. The results demonstrate that the developed model can be utilized as a tool to mitigate subjectivity and provide a more objective and reliable ranking even in the long term. It also highlights the correlation between selected attributes and the context of investment opportunities. Attributes alone are necessary but not sufficient to influence rankings holistically. Ultimately, the study’s findings shed light on the interplay between attributes and investment contexts, emphasizing their interdependence.

The lower limit of the height of the WCFZ was preliminarily determined via borehole televiewer observation, and the maximum height of the WCFZ in the working face was further determined via numerical simulation and empirical analysis. The prediction results obtained via the traditional empirical formulas are unsuitable for working faces with large panel widths. For the studied working face, considering its actual geological background, the deformation and failure characteristics of the overlying rock under six different panel width conditions were simulated via numerical simulation, and it was found that the height of the WCFZ exhibits a good natural logarithmic relationship with the panel width. On the basis of the statistics of data collected from 58 cases of fully mechanized coal faces with normal panel widths in the North China-type coal field, the applicability of the logarithmic variation in the in situ data was analysed and compared. The accuracy of the logarithmic variation was verified by theoretical analysis, revealing that the internal factor controlling this variation is the decrease in the burial depth of the unfractured rock stratum. The case study with the panel width of the working face of 330 m extends the applicability of the abovementioned variation to panel widths greater than 300 m in North China-type coalfields, and 300 m was proposed as the threshold panel width at which the development of the WCFZ slows.
