THE IMPACT OF ROŞIUŢA COAL MINING FROM GORJ COUNTY ON AIR QUALITY
Journal Title: Annals. Food Science and Technology - Year 2011, Vol 12, Issue 2
Abstract
The E.M.C. Rosiuta excavation has as purpose of activity, lignite extraction from the south-west platform of the coal basin from Oltenia. The Rosiuta represents a productive subunit of this enterprise. The extracted lignite is used the thermal plants from the south-western part of the country. The development of the production capacity of the quarries in the area represent a good solution to ensure, from internal sources, the coal necessary to produce electricity, with social -economic implications regarding unemployment reduction in Motru area and implicitly the increase of the standard of living for the population of the area, as well as avoiding currency expenses for coal transportation and supply from import. Extension of VALEA STIUCANI exterior waste dump is necessary for further storage of the waste resulted from ROŞIUŢA quarry. Due to the fact that the waste consists of diorite sand, clays and sands intercalated between the lignite ones in order to be able to work within the coal deposit in dept, it is necessary to excavate large amounts of waste that has to be stored in waste dumps. The setteled powders, the suspension powders and the fraction PM10 were experimentally assessed. The experimental results prove that the coal storehouse has a negative impact on the air, the settlement of the storehouse being close by the inhabited area. The surface mining in order to extract coal ores represents a classical solution to produce raw material necessary to obtain electricity and heat, but with the cost of environmental pollution during the mining and after the economic activities stops. Solutions to optimize the mining process must be discovered and the technological solutions of storage for the coal dumps and tailings, to obtain minimal impact on the environmental quality and especially on the quality of the air. This paper presents the impact upon air produced by industrial activities realised in the mining exploitation on Rosiuta area, Gorj County.
