Fine ash fractions can have a strong degradation effect on the environment, especially in the period of strong winds, which can lead to the major environmental problems, especially violations of public health, bearing in mind that this raw material categorized as the hazardous waste. This especially should be kept in mind when mechanized cleaning and transport of ash and slag from the cassettes in Medoševac to the landfill for permanent disposal of ash in the vicinity of nearby villages. In a view of its physical and chemical characteristics, the negative effects of ash on the environment are reflected through the pollution of air, surface and ground water, land, to the agricultural products, which directly threatens human health, in areas where those are. If it is possible to work on reducing the emergence due to minimize the occurrence of ash and slag. Regarding to the use of ash and slag in other industries, this type of materials can have significant use in the field of civil construction as a foundation for roads. The use of ash and slag like secondary materials could greatly reduce the amount of waste that is disposed in a landfill. No 1,2010. 67 MINING ENGINEERING
