    معدن کاری و استخراج منابع معدنی علاوه بر اینکه یک صنعت جهانی است نقش مهمی را نیز در اقتصاد و سرنوشت هر کشوری دارد. با توجه به اینکه عملیات معدن کاری در مناطق دورافتاده و حساس از نظر زیست محیطی و یا کمتر توسعه یافته انجام می گیرد، اما نمی توان از این نکته مهم چشم پوشی نمود که مشکلات فراوانی همچون آلودگی آب های سطحی و آب های زیرزمینی و مرگ ومیر آبزیان را به وجود می آورد. اگر معدن کاری به شیوه ای پایدار مدیریت شود، علاوه بر ایجاد شغل، نوآوری و ترغیب سرمایه گذاری باعث تقویت زیرساخت های حیاتی هر کشوری خواهد شد. در صورت مدیریت ضعیف، معدن کاری منجر به تخریب محیط زیست، جابه جایی جمعیت، نابرابری و افزایش درگیری و سایر چالش ها می شود. معدنکاری سبز نوع مدرنی از الگوی معدن کاری است که هدف اصلی آن استخراج منابع به صورت بهینه و به مقدار کافی ،کاهش اثرات زیست محیطی، ایجاد توازن و بهینه سازی منافع سرمایه گذاری و جامعه بر اساس شاخص هایی توسعه پایدار است که توسط سازمان ملل (SDG) معرفی شده اند. معدن به عنوان یکی از قدیمی ترین فعالیت های انسان می باشد که توسعه اقتصادی، فرهنگی و فنی جوامع و کشورها را در طول تاریخ بر عهده داشته است. هدف از شاخص های معرفی شده سازمان ملل دستیابی به توسعه پایدار در معدن کاری و در نظر گرفتن تمامی ابعاد موثر در زندگی ساکنان اطراف معادن اعم از اقتصادی، اجتماعی و محیط زیستی می باشد. در این تحقیق توصیفی-کتابخانه ای، به بررسی و بحث در مورد تطابق بین فعالیت معدنی و SDGها و ارتباط معدن با محیط پیرامون پرداخته می شود. نخست به تعریف ابعاد توسعه و در نهایت به بررسی شاخص های توسعه پایدار پرداخته می شود.

    Mining and extraction of mineral resources, in addition to being a global industry, it also plays an important role in the economy and destiny of any country. Due to the fact that mining operations are carried out in remote and environmentally sensitive or less developed areas, we cannot ignore the important point that it causes many problems such as surface water and ground water pollution and aquatic mortality. If mining is managed in a sustainable manner, in addition to creating jobs, innovation and encouraging investment, it will strengthen the critical infrastructure of any country. In the case of poor management, mining leads to environmental destruction, population displacement, inequality and increased conflict and other challenges. If mining is managed in a sustainable manner, so creating jobs, innovation and encouraging investment, it will strengthen the critical infrastructure of any country. In case of poor management, mining leads to environmental destruction, population displacement, inequality and increased conflict and other challenges. Green mining is a modern type of mining model whose main goal is to extract resources optimally and in sufficient quantity, reduce environmental impacts, create balance and optimize the benefits of investment and society based on sustainable development indicators introduced by the United Nations (SDG). Mining is one of the oldest human activities that has been responsible for the economic, cultural and technical development of societies and countries throughout history. The goal of the indicators introduced by the United Nations is to achieve sustainable development in mining and to take into account all aspects that are effective in the lives of the residents around the mines, including economic, social and environmental aspects. In this descriptive-library research, the compatibility between mining activity and SDGs and the relationship between mining and the surrounding environment are investigated and discussed. First, the dimensions of development are defined and finally, sustainable development indicators are examined.Mining and extraction of mineral resources, in addition to being a global industry, it also plays an important role in the economy and destiny of any country.

    Dinagat Islands hold most of the mineral deposits in the Philippines and have been among the largest mining contributors in the country since 1939. Aside from a massive mining industry, logging is also intensive in this group of islands potentially imperiling its remaining biodiversity. This study primarily aims to determine the species composition of terrestrial vertebrates (amphibians, reptiles, birds, mammals) in two study areas categorized as modified habitats (mining area and logging area) in the Dinagat Islands. These wildlife species are important bio-indicators as they show sensitivity of the species to anthropogenic disturbances. Suitable field survey methods were conducted for the taxa established and a quantitative analysis was performed to determine the diversity and similarity of the species between the study areas. A total of 65 species were identified in the two study areas: 33 species were exclusively identified in the mining area, 49 species were exclusively identified in the logging area, and 17 species were found in the both study areas. It should be noted that among the 65 species, 41 species are either endemic to Mindanao and/or the Philippines, and two species were endemic to Dinagat Islands. This study also recordedthe newly described coral snake endemic to the island, Calliophis salitan Brown, Smart, Leviton and Smith. This study indicates that although Dinagat Islands is modified by anthropogenic activities, the terrestrial vertebrate species are thriving. Intensive survey in other modified habitats in Dinagat Islands is the next-step forward to take into account existing wildlife to improve conservation decisions, planning and management on the islands.

    The presence of heavy metals (metals with a density of over than 5 g cm-3) in the soil surfaces, are mainly due to industrial and mining activities, fuel combustion, etc. Although some of the metals are essential elements for plants, in the high concentrations have toxic effects on plants. Some of the plants those grown in mining areas are resistant to high concentration of heavy metals. The aim of this study was to assess the iron resistance of plant species in Esteghlale-e- Abadehe fire clay mine. Therefore, soil samples from six mine area and a control were collected. Plant species were collected too. After sampling and preparation of samples parameters: acidity, electrical conductivity, exchangeable and total iron of soil samples and plant iron content was determined. The results showed that exchangeable and total amounts of iron in mining areas were significantly higher than compared amounts in control site. It can be concluded from analyses of plant shoot iron concentrations that some of the plant species of mine areas are resistant to iron stress and use either avoidance or tolerance strategy for the resistance.
