Environmental management in North American mining sector

Abstract: This paper reviews the environmental issues and management practices in the mining sector in the North America. The sustainable measures on waste management are recognized as one of the most serious environmental concerns in the mining industry. For mining activities, it will be no surprise that the metal recovery reagents and acid effluents are a threat to the ecosystem as well as hazards to human health. In addition, poor air quality and ventilation in underground mines can lead to occupational illness and death of workers. Electricity usage and fuel consumption are major factors that contribute to greenhouse gases. On the other hand, many sustainability challenges are faced in the management of tailings and disposal of waste rock. This paper aims to highlight the problems that arise due to poor air quality and acid mine drainage. The paper also addresses some of the advantages and limitations of tailing and waste rock management that still have to be studied in context of the mining sector. This paper suggests that implementation of suitable environmental management tools like life cycle assessment (LCA), cleaner production technologies (CPTs), and multicriteria decision analysis (MCD) are important as it ultimately lead to improve environmental performance and enabling a mine to focus on the next stage of sustainability.

Impact of Diesel Equipment on Ventilation in Quebec Underground Mines

Abstract: Diesel powered equipment has gained huge popularity in underground mines around the world in the last several decades due to their productivity, versatility and flexibility. However, this equipment emits important amounts of gaseous and particulate pollutants that necessitate a considerable increase in ventilation airflow requirements in order to satisfy the health and safety regulations. The first part of the paper describes a survey conducted at Laval University of the diesel equipment and ventilation practices in underground metal mines in the province of Quebec. The objective of this survey was to collect information on the mine characteristics & the diesel fleets operated in those mines and then study their impact on underground air quality. The paper presents and discusses the airflows quantities used for underground ventilation, the airflows quantities per tonne mined and the airflow quantities per kW of diesel power installed in the participating mines. Finally, this paper compared results with other similar surveys from the literature.
