This study focuses on evaluating the concentrations of heavy metals in surface water near the Legadembi tailings dams. The mean concentrations (in µg/L) of various heavy metals including: arsenic (As), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), mercury (Hg), molybdenum (Mo), nickel (Ni), lead (Pb), antimony (Sb), selenium (Se), thallium (Tl), uranium (U), vanadium (V), tungsten (W), zinc (Zn), and zirconium (Zr) were determined: 79.7, 0.15, 162.3, 0.66, 18.1, 0.01, 22.5, 55.7, 0.30, 3.3, 2.6, 0.01, 0.49, 1.7, 136.1, 5.7, and 0.32, respectively. Moreover, the concentrations of metals in the surface water exhibit a temporal or seasonal variation, which makes the study interesting. Overall, the results indicate that the concentrations of heavy metals generally decrease as the distance from the tailings dam increases, signifying the downstream dilution effect. Nevertheless, it was observed that dams two and three surpassed both national and international standards for certain heavy metals, such as As, Co, and W. These dams, which are accessible to domestic animals, would pose a potential health risk to humans and animals.","PeriodicalId":37284,"journal":{"name":"Journal of Sustainable Mining","volume":"25 1","pages":"97-107"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147916026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among these challenges is the management of tailings. This study focuses on investigating surface disposal of non-cemented paste tailings, particularly the effect of water content, freeze-thaw cycles (FTC, defined as freezing the sample to –20°C and thawing it to +20°C), and ambient temperature on the mechanical characteristics and thermophysical properties of paste tailings. The potential for maintaining non-cemented tailings in a frozen state year-round is also investigated through field-scale numerical simulations. Experiment results of thermophysical properties of tailings with water content, freeze-thaw cycles and ambient temperatures varying in the 0–30 wt% range, 0–15 range and –5 – –15°C range, respectively, suggest higher thermal conductivity of paste tailings compared with dry porous tailings, particularly at lower temperatures. The highest unconfined compression strength of 0.93 MPa is obtained for the sample with 30 wt% water content, subjected to 15 FTCs at –15°C. This study suggests that, unlike frozen cemented paste tailings, frozen non-cemented paste tailings exhibit higher strength when subjected to more FTCs, making them more resilient in cold regions. Furthermore, the field-scale numerical simulation results support the practicality aspect of frozen paste tailings as a climate change adaptation strategy if combined with artificial ground freezing.","PeriodicalId":37284,"journal":{"name":"Journal of Sustainable Mining","volume":"25 1","pages":"1-17"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147903574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was carried out in twelve states in Nigeria and covered the six geopolitical zones in Nigeria. Data was collected through a questionnaire and interviews carried out separately with community members and company representatives. The study investigated ten categories of mining impacts such as socioeconomic, environmental, health, physical and so on. To gauge the perceptions of the respondents on the different impact categories, the Likert scale was used. The Student’s t-test was then used to determine whether there are statistically significant differences in perceptions in each impact category. The study findings showed significant differences in how communities and mining companies perceive the impacts of mining. Out of the ten impact categories assessed, statistically significant differences in perception were observed in nine categories. The only category where there was no significant difference in perception between mining companies and communities was related to conflicts arising from mining operations. Shrinking these perception gaps is key to ensuring sustainable mining practices in Nigeria.","PeriodicalId":37284,"journal":{"name":"Journal of Sustainable Mining","volume":"24 1","pages":"89-101"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147886944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vibrock (V9000) seismograph was used to take readings related to ground vibrations and noise generated during all blasting operations that took place in the quarry for a period of one year. The results obtained indicate that the average ground vibration readings fall between 0.25mm/s to 3.6mm/s and the average noise decibel generated during the blasting operations between 35 to 158 dB. An artificial neural network (ANN) model is developed in this study for the prediction of blast-induced ground vibration and noise level. The proposed ANN model was compared with existing empirical models and was found to give the highest prediction accuracy. It was revealed that both noises generated and ground vibrations during all blasting operations increase with an increase in explosive maximum instantaneous charge. Additionally, the measuring equipment distance from the blast site was also revealed to have a negative correlation with noise generated and ground vibrations.","PeriodicalId":37284,"journal":{"name":"Journal of Sustainable Mining","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136068967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
