Continuous improvement in environmental management assists in the achievement of sustainability goals for the processing of minerals. The use of regular internal environmental audits (scored or unscored) which form an integral component of an Environmental Management System (EMS), provide demonstrable evidence of this improvement._x000D_
Case studies are presented for a number of major coal mines in the Hunter Valley, where regular internal environmental audits have been undertaken every two to three months, over periods varying from 18 months to five years. Examples of the benefits of improved environmental performance (driven by the audit process) to sustainable development are provided._x000D_
The auditing process as described here for coal mines, and coal handling and preparation plants, is equally applicable to the processing of other mineral ores, metalliferous mines, quarries, and oil and gas projects.
