The International Mine Ventilation Congress series has become a very important way for those with an interest in mine ventilation and atmosphere control to share information and new developments. The Congresses to date have been the pre-eminent meetings for discussion of cutting-edge research and innovative technologies relevant to mine atmospheres. Mines that will operate for the next few decades are being designed today. With the current pace of technology change, significant new developments in mine ventilation can be expected. The Congress provided a timely review of innovative approaches being developed. It is hoped that it will assist the mining industry to meet the challenge of more effective management of mine ventilation issues. The mining industry is under unprecedented technical, commercial and social pressures to continuously improve its performance. It is an industry that on a global stage has always been cyclical. Within the global economy there are short good times followed by extended periods of low prices. There is increasing shareholder demand for performance in all parts of the cycle. Evolution and operating excellence including outstanding technological endeavour have become essential for survival. All papers in the Proceedings have been peer reviewed and edited to ensure the highest relevance and quality.
