RESIDUAL RISKS ENCOUNTERED IN COAL MINING AND CLOSURE OF MINES IN THE JIU VALLEY - ROMANIA
Abstract
Restructuring of the exploitation of the coal deposit in the carboniferous area of the Jiu Valley in Romania is part of a quarter-century closure program and the use of minerals has been reduced by 10 times compare with the production achieved at the level 1989. In the last 10 years, the use of the coal in the steel production was abandoned, the production being processed only for electric and thermal energy needs. At present, 4 production units (Lonea, Livezeni, Vulcan and Lupeni) are operating in this area, out of which 2 are scheduled to cease operations and start the closure process. In Romania's energy strategy for the next 12 years, although it opts for a diversified energy mix in the exploitation of primary resources, the coal needed for the production of electric and thermal energy will be provided only by the production of the Vulcan and Livezeni mines and will be completed with coal from aboard, that until to reconfigure the thermo - energetic capacities based on another more efficient primary energy resource. Closure of a coal mine is based on a series of specific phased works over periods of time in which it is necessary to take into account a number of technical risk factors to which underground workers are exposed, as well as the open ore body. On top of this is need to add the negative impact of the political and social risk factors, the consequences of which are economic underdevelopment and population poverty. Managing these risks by analysing their causes, assessment and their evaluation, eventual measures to mitigate or anticipate them, to achieve progress or regress, is part of the subject of this paper.
