Early efforts to address sustainability within the mining industry (GMI and ICMM) did not create a common set of protocols by which individual operations could be clearly ranked on their performance. The Mining Association of Canada’s Towards Sustainable Mining (TSM) program provides protocols to address biodiversity, tailings management, crisis management, safety and health, energy/GHGs, and aboriginal/community engagement. The TSM program has been mandatory for MAC members to implement at their Canadian operations since 2004. Progress along these indicators shows how well the industry is doing at addressing sustainability along each concept, and where further progress is still needed.

The mining industry exists because humans need mining commodities to meet their daily needs such as motor vehicles, mobile phones, electronic equipment and others. Mining commodities as mentioned in Government Regulation No. 23 of 2010 on Implementation of Mineral and Coal Mining Business Activities are radioactive minerals, metal minerals, nonmetallic minerals, rocks and coal. Mineral and coal mining is conducted to obtain the mining commodities through production operations. Mining and coal mining companies have an obligation to ensure that the mining environment in particular after the post production operation or post mining continues. The survey research aims to examine technically the post-mining plan in coal mining of PT Samantaka Batubara in Indragiri Hulu Regency of Riau Province towards the sustainability of the mining environment. The results indicate that the post-mining plan of PT Samantaka Batubara has met the technical aspects required in post mining planning for a sustainable mining environment. Postponement of post-mining land of PT Samantaka Batubara for garden and forest zone. The results of this study are expected to be useful and can be used by stakeholders, academics, researchers, practitioners and associations of mining, and the environment.

This article quantitatively examines the patterns of collaborative research in the field of sustainable development of the mining sector. The study is based on bibliographic data of 4420 Scopus index research articles published in the period 1983–2018. Both trend and network analyses were employed in this investigation. The results show a rise in the number of joint articles and in the average number of the authors per joint article. Moreover, no increase in the relative numbers of interinstitutional, international, and cross-sector articles was observed. The collaborative efforts, in terms of the co-authorships, were taken mostly among authors affiliated with the one sector—namely, science and research institutions. This indicates that funding agencies should foster more intensively the cross-sector research collaborations for sustainable mining. However, the most collaborative countries formed cross-continental clusters, thus indicating the global character of research collaboration for sustainable mining. This, in turn, can support solving mining issues with long-term implications, especially the impact of the mining industry on the environment.

Early efforts to address sustainability within the mining industry (GMI and ICMM) did not create a common set of protocols by which individual operations could be clearly ranked on their performance. Although the Global Reporting Initiative (GRI) does provide protocols for the reporting of sustainability indicators for mining operations, GRI-based reports include a letter grade based on report completeness, not performance on the actual indicators. The Mining Association of Canada's Towards Sustainable Mining (TSM) program provides protocols to address biodiversity, tailings management, crisis management, safety and health, energy/GHGs, and Aboriginal/community engagement. The TSM-based reports grade mining operation performance at implementing programs and systems to address each of these topics. Progress along these indicators tells us how well the industry is doing at addressing sustainability along each concept, and where further progress is still needed.


The contribution of mining industry in the economic development of a country is vital. It boosts the economy, provides material to build infrastructures, increases employment and provide goods required for daily use. Despite being fundamental for a country’s growth, mining industry has always faced the flak of environmentalists and conservationists for having failed to take preventive and corrective measures to remedy the damage caused to the environment due to the mining activity. The environmental risks posed by the mining activity are catastrophic and there is an exigency to attain a rational balance between the mining activity and environment with an ultimate aim to achieve sustainable development. The mining activity disrupts the entire ecosystem and is a threat to biodiversity. To envisage and analyze the environmental impacts of a proposed mining project, Environment Impact Assessment is inevitable. This paper throws light on the various techniques by which mining is carried out, the importance of Sustainable Mining and Environmental Impact Assessment, the process followed to prepare the assessment report and the role which it plays in environmental protection. The paper also highlights the significant role rehabilitation and reclamation techniques play in potentially improving the damage caused due to the mining activity and some of the effective reclamation processes that can be employed to restore the abandoned mine sites and regulate the ongoing mining operations.

Calcium carbonate scaling often is a critical problem for recycled board mills that have closed water circuits. The objective of this study was to determine local scaling risks throughout the production process. To predict scaling potential, we calculated several saturation indexes, based on speciation determined from detailed water analyses. Calculated scaling trends are in accordance with observed dissolution and precipitation of calcium carbonate in the process, when considering local aeration phenomena. The importance of volatile fatty acids (resulting from anaerobic bacterial activity) in calco-carbonic equilibriums is discussed, and taken into account in the speciation calculation. We also demonstrate the need to measure inorganic carbon instead of alkalinity in such conditions. This makes typical scaling indexes, such as the Ryznar Stability Index, irrelevant to predict scaling risk in closed circuit conditions; thus, it is necessary to use general speciation methods, as described in this paper.
