Coal Mine Velenje with production of app 4 Mt of lignite per year is also emitting coal gases and various odours. Occasionally detected odours on the surface of the coal mine area and some of the nearby settlements may also result from the coal mine ventilation system and mined coal deposit on the surface. In particular Ventilation station Pesje, which is located closer to Velenje, with its emissions represents an occasional locally recognized environmental problem. On the one hand the legislation, which more and more sharpens and on the other hand the vision and corporate social responsibility dictates that the occurrence of odours Coal Mine Velenje undertakes thoroughly and fundamentally. The objectives of this research are to develop and implement a robust odour emission monitoring system and collect the necessary data that are necessary to develop an understanding of formation and dispersion of odorous compounds at the process of underground coal excavation and surface coal deposition. The research activities are divided in three main topics:
- Identification and evaluation of odour sources.
- Monitoring of odour emissions from sources on the surface (using chemical analysis and olfactomety).
- Design and implementation of odour dispersion model.
