“…The satellite image classification-derived change detection is also an important approach for evaluating the mine site revegetation, e.g., [13,24,25,28,[30][31][32][33][34][35]. The resulting classification and change-detection maps further substantiated the vegetation-cover change derived from the NDVI analysis.…”

“…In many of these studies, the multi-temporal multispectral (e.g., [13,16,[19][20][21]) or hyperspectral (e.g., [17,18]) imagery data were used to derive the vegetation indices and/or the classified land cover types, which were then utilized to track the mine site revegetation. In addition, remote sensing techniques have also been widely applied to assessing rehabilitation and revegetation at mine sites across the world, such as in Australia [23,24], Brazil [25,26], China [27][28][29], Europe [30][31][32][33], and USA [34,35].…”

Remote Sensing-Based Revegetation Assessment at Post-Closure Mine Sites in Canada

The environmental legacy of post-closure mine sites poses a significant risk to the sustainability of mining operations and natural resource development. This study aims to advance the understanding of sustainable mine site reclamation behavior in Canada by using multi-temporal Landsat satellite images to examine the long-term land cover changes at post-closure mine sites. Six representative post-closure mine sites were selected for the evaluation and comparison. The Normalized Difference Vegetation Index (NDVI) analysis, Landsat image classification, post-classification change detection, and Regrowth Index (RI) analysis were conducted to assess the speed and extent of landscape and vegetation recovery at the target mine sites. A significant vegetation recovery was quantified for the mine sites that have experienced active reclamation activities. In contrast, the post-closure mine area undergoing only passive revegetation typically demonstrated a slow and minor increase in vegetation over time. The actively revegetated mine sites can typically be restored to a vegetation cover level that equals or is better than the pre-mining situation. This work confirms that active reclamation and revegetation at post-closure mine sites is critically important in sustainable mining. The quantified mine site reclamation behavior and the relevant sustainable practices would be useful for evidence-based sustainable resource management in Canada.

“…The geotechnical land reclamation technology, which enables maximum preservation of the soil layer to be later on placed on the surface of waste rock dumps and allows maximal reduction of greenhouse gas emission, is in detail described in the study [53]. For the conditions of Siberia in Russia, the procedure of geotechnical land reclamation in combination with overburden stripping on the upper bench of open pits is scientifically substantiated [55].…”

В статье представлено исследование динамики производства работ по лесной рекультивации на породных отвалах, отсыпанных в ходе добычи угля открытым способом на территории Иркутской области. По данным дистанционного зондирования за 35-летний период установлена позитивная динамика в проведении лесной рекультивации. Весь объем работ по лесовосстановительной экологии выполнен на породных отвалах, отсыпанных в ходе открытой разработки Черемховского, Азейского, Мугунского и Жеронского угольных месторождений.
