Sleep disorders are prevalent clinical issues, adversely affecting overall health, safety, and quality of life by disrupting natural sleep patterns. Inadequate or non-restorative sleep can disrupt normal physical, mental, social, and emotional functioning. The primary approach to addressing sleep disorders involves identifying their root causes and dealing with the associated conditions. This study explores sleep disorders arising from mining activities, focusing on the impact of explosions on residents near gold mines in Iran. Conducted over one month, the research aimed to assess sleep quality using the Pittsburgh Sleep Quality Index (PSQI) questionnaire. After collecting data through this standardized questionnaire, analysis was conducted. Results from the questionnaire analysis revealed that 72.5% of individuals residing in the mining area reported experiencing sleep disorders. Significant differences in PSQI indices between men and women were identified, suggesting that women in the studied rural area perceived mining activities as significantly impacting their sleep quality and daily functioning. Furthermore, no significant differences were observed in sleep quality indices between singles and married participants, except for the use of sleep-inducing medications among employed and unemployed groups in the study community. Noteworthy, many workers, particularly those from the rural male population employed in mining, face various harmful factors such as explosions and noise, potentially contributing to the impact of mining on residents in the area. The study results can inform the development of effective strategies to mitigate the negative consequences of mining

One of the most important steps involved in mining operations is to select an appropriate extraction method for mine resources. After choosing the extraction method, it is usually impossible to replace it with another one because it may be so expensive that implementation of the entire project could be economically impossible. Choosing a mining method depends on the geological and geometrical characteristics of the mine. Due to the complexity of the process of choosing an appropriate mining method and the effect of the parameters involved on the results of this process, it is necessary to utilize the new decision-making methods that have the ability to consider the relationship between the existing parameters and the mining methods. Grey and TODIM (an acronym in Portuguese, i.e. Tomada de Decisão Interativa Multicritério) decision-making methods are among the existing ones, which in addition to the convenience, show high accuracy. The proposed models are presented to determine the best mining method in the Gol-e-gohar iron ore mine in Iran. The results obtained are compared with the methods used in the previous research works. Among the decision-making methods introduced, the open pit mining method is the most appropriate option and the square-set mining is the worst one.
