Integrating the environmental and sustainable development agendas into minerals education

Changing public perceptions of the environmental acceptability of mining and minerals processing facilities have changed the industry and mining schools have started to respond by adding environmental content to their minerals curricula. Proactive and preventive environmental strategies, including Cleaner Production and sustainable development, are preferred but mining and minerals processing companies and mining schools generally have limited know-how in those areas. Vice versa, Cleaner Production specialists generally have limited experience in the mining and minerals processing sectors, and should endeavour to employ their expertise and know-how to address the environmental and sustainable development challenges in those sectors. The critical task for mining schools is to educate environmentally literate graduates who are able to recognise potentially adverse impacts of mining and minerals processing on the environment and to contribute from a sound background in geology, mining or metallurgy, to the characterisation, minimisation and management of these environmental impacts. This paper focuses on integrating the environmental and sustainable development agendas in minerals tertiary education. It highlights trends in employers' recruitment criteria and in minerals curricula, and argues in favour of strengthening the environmental component of minerals curricula. The paper provides a framework for integrating the environmental and sustainable development agendas in minerals tertiary curricula. Integration of environmental aspects into core disciplinary courses, by means such as environmental examples, cases and problem-solving tasks, is critical to make environmental literacy programmes successful.

Climate change and mining in Canada

Climate is an important component of the operating environment for the Canadian mining sector. However, in recent years mines across Canada have been affected by significant climatic hazards, several which are regarded to be symptomatic of climate change. For the mining sector, climate change is a pressing environmental threat and a significant business risk. The extent to which the mining sector is able to mitigate its own impact and adapt to climate change will affect its long-term success and prosperity, and have profound economic consequences for host communities. This paper draws upon case studies conducted with mining operations in Canada involving in-depth interviews with mining professionals and analysis of secondary sources to characterize the vulnerability of the Canadian mining industry to climate change. Five key findings are discussed: i) mines in the case studies are affected by climate events that are indicative of climate change, with examples of negative impacts over the past decade; ii) most mine infrastructure has been designed assuming that the climate is not changing; iii) most industry stakeholders interviewed view climate change as a minor concern; iv) limited adaption planning for future climate change is underway; v) significant vulnerabilities exist in the post-operational phase of mines. This paper argues for greater collaboration among mining companies, regulators, scientists and other industry stakeholders to develop practical adaptation strategies that can be integrated into existing and new mine operations, including in the post-operational phase.

Environmental management and life cycle approaches in the Mexican mining industry

Mexico ranks among the 11 major producer countries of minerals worldwide; its open pit and underground systems are 500 years old. This paper presents an overview of the Mexican mining industry from technological development, historical and economic perspectives. The efforts made by mining companies to address issues of environmental management and sustainable development expressed in national and international frameworks, as well as the Mexican environmental regulatory framework for the mining sector, are analyzed. Since, among others, life cycle assessment (LCA) has been recognized as a key topic to promote sustainable development in the Latin American and Caribbean region, this paper also examines the application of LCA in mining. Two life cycle approaches are presented: a national life cycle inventory for base metals, and an integral life cycle model for the management of mining processes.     

内蒙古乌达矿区土壤多环芳烃空间分布特征及分析

随着我国煤炭行业的不断发展,有关煤矿区及周边有机污染物研究正逐渐受到全社会广泛关注。本文利用气相色谱-质谱方法对内蒙古乌达矿区不同土地利用类型的土壤样品中多环芳烃含量和空间分布情况进行分析。结果表明,研究区土壤中8种多环芳烃的总含量均值为2 054ng/g。尤其发现,土壤样品中烷基多环芳烃含量显著高于母体多环芳烃。从空间分布上来看,多环芳烃含量较高的位置集中在研究区西南方位,以8号水泥厂采样点和9号工业园采样点为中心分布。相关性分析表明,土壤中母体多环芳烃和烷基取代多环芳烃相关性较好,且环数越高,相关性越强,而多环芳烃与重金属汞并不存在明显的相关性。研究乌达矿区土壤中多环芳烃的污染情况和空间分布特征,分析煤矿开采及煤火问题对周边环境的影响,以期为煤矿区周围环境治理提供参考。

Corporate social responsibility in the mining industry: Exploring trends in social and environmental disclosure

In recent years, concerns about the sustainability and social responsibility (CSR) of businesses have become an increasingly high profile issue in many countries and industries, none more so than the mining industry. For mining, one outcome of the CSR agenda is the increasing need for individual companies to justify their existence and document their performance through the disclosure of social and environmental information. This paper explores recent trends in the reporting of such impacts and issues in the global mining industry. It offers a detailed review of the development of the media of social and environmental disclosure in the mining industry, and of the factors that drive the development of such disclosure. A temporal analysis of the recent trends in disclosure using a case study of the world's 10 largest mining companies is presented. Whilst there is evidence of increasing sophistication in the development of social and environmental disclosure, there is considerable variation in the maturity of reporting content and styles of these companies. The paper offers a simple classification of reporting companies, from ‘leaders’ to ‘laggards’. Stronger leadership and co-operation from the top reporting companies is necessary to support the laggards of the industry.
