Main air pollution problem due to mining is dust. This monograph develops emission factors to quantify mine dust emission and established a new methodology named as factal analysis and evaluated the actual contribution of air pollutants by a project in question and from other sources, their emission rate and dispersion characteristics . This is based on the changes of the wind directions and air quality at the monitoring stations when they are upwind and downwind from the mine. The methods are applied successfully in real life situation and Patents are obtained . A scheme is...
