    Coal Mine Methane Country Profiles, Chapter 29, June 2015

    29 Romania 29.1 Summary of Coal Industry 29.1.1 ROLE OF COAL IN ROMANIA Coal accounts for 29 percent of energy production in Romania (EIA, 2014). Romania’s proven coal reserves are estimated at about 291 million tonnes (Mmt) and the country ranks 20th worldwide in coal production (see Table 29-1). More than 80 percent of Romanian lignite reserves can be mined profitably in opencast mines, while the remaining 20 percent require underground mining (Euracoal, 2014; WEC, 2000). Table 29-1. Romania’s Coal Reserves and Production Sub- Anthracite & bituminous Total Global Rank Indicator Bituminous & Lignite (million tonnes) (# and %) (million tonnes) (million tonnes) Estimated Proved Coal Reserves 10.0 281.0 291.0 43 (0.033%) (2011) Annual Coal Production (2012) 0.04 33.99 34.03 20 (0.43%) Source: EIA (2014) Figure 29-1 shows the distribution of lignite and hard coalfields in Romania. The coal deposits are grouped into four zones: Zone I, mainly located in the Southern Carpathian Mountains, includes all the high-grade coal such as anthracite, pit coal (higher ranking than brown coal – bituminous and sub-bituminous), and brown coal (lignite) from the Petrosani, Anina and Tebea-Brad basins. Zone II, located within the Pre-Carpathian creep, between the Olt and Valea Buzaului rivers, includes the lignite deposits of Campulung, Sotanga, Filipestii de Padure, and Ceptura. The coal basins of the Eastern Carpathian are also included within this zone: Baraolt-Virghis (lignite) and Comanesti-Bacau (brown coal). More than 90 percent of Romanian coal reserves are located within Zone II, namely in the mining basins of the Oltenia Region.

    The Social Impact of Mine Closure in the Jiu Valley

    E3S Web of Conferences 239, 00004 (2021) https://doi.org/10.1051/e3sconf/202123900004 ICREN 2020 The social impact of mine closure in the Jiu Valley Izabella Kovacs*, Sorin Simion, Alin Irimia, Ligia Ioana Tuhuţ , and Gheorghe Daniel Florea National Institute for Research and Development in Mine Safety and Protection to Explosion – INSEMEX Petrosani, 32-34 G-ral Vasile Milea Street, Petrosani 332047, Romania Abstract. The impact of transition periods is experienced by the local population and economy as a result of mining activities closure and dismissal of a large number of workers followed by diversification of employment and career reorientation opportunities. The aim of the paper is to highlight the impact generated by closure of mining operations on local society and economy as well as identifying opportunities for harmonious development of communities in the Jiu Valley. Following the assessment of the social impact of mining activities closure, we found a rising tendency of unemployment rate among the middle-aged population that did not benefit from vocational retraining and the growing tendency of young people to leave the region for strictly economic reasons leading to widespread social aging. 1 Restructuring of mi ning activity in Romania and the Jiu Valley Jiu Valley is a micro-region in Hunedoara County, located between the Retezat and Parâng Mountains (fig.1). It consists of 3 cities: Petrila, Uricani and Aninoasa and 3 municipalities - Petroșani, Lupeni and Vulcan. Officially, the micro-region has no rural areas, because it has been incorporated into municipalities or cities, being considered urban. * Corresponding author: [email protected] © The Authors, published by EDP Sciences.

Restructuring the mining industry, the large number of layoffs has led to rapid increase in unemployment and decline in living standards of the inhabitants of Petrosani Depression . In these circumstances, from the local authorities have identified tourism development as a complementary activity / alternative to local economy. Key words : mountain environment, tourism, mining, unemployment INTRODUCTION In the south of Hunedoara county, in a triangle proved to be golden , on the border between Transylvania, Banat and the Romanian Country, lies an area known generically under denu - groom " Jiu Valley " and geographi- cally that " Petrosani Depression " region that has earned the reputation as the " Land of black Diamond " (fig. 1). Fig. 1. Layout and composition Jiu Valley 195 REASON Jiu Valley - a region made up of three municipalities: Petrosani,Lupeni, Vulcan and three cities : Petrila, Uricani, alder, with a total population of 120 734 inhabitants, the main economic activity was the coal mining industry in the years after 1990 suffered transformations in economic, social and demographic changes resulting from the restructuring of this activity sector. Besides mining sector restructuring , the reference faced available - saw and activities related to mining or provide services to the mining sector, which has led to diponibilizări from these activities, leading to a high rate of unemployment in the area.

The process of reducing disparities in Romania is maintaining sustained growth rates during 2007 - 2013, keeping at the same time, macroeconomic equilibrium levels more stable. The determining factor for economic growth, on the open market a competitor, is to increase economic competitiveness. In addition, exploitation of competitive advantages must be a permanent objective, taking into account both European trends, and the challenges of globalization. Therefore, increasing competitiveness should not be viewed as a process of exploitation of short-term advantages (eg low cost of labor), but as a process of building an economic structure based on capital investment and research processes, development and innovation. In other words, articulating a vision of convergence on medium and long term need to consider developing a knowledge-based economy. Although substantial progress in recent years, Romania has serious gaps in competitiveness in relation to the Western and Central Europe. The reasons for this sluggishness can be found in all the elements that determine the competitive ability. All are translated, ultimately, in a low productivity, which defines competitiveness problem in Romania.

    Fondatia Pentru Literatură Si Artă ,,REGELE CA.ROL Al D-Lea''

    UN A.SEZĂMÂNT REGAL: Fondatia pentru' Literatură si Artă ,,REGELE' CA.ROL al D-lea''' Petruţa BURLACU Potrivit unei vechi şi bune tradiţii, regii României s-au preocupat de problemele culturale ale ţării, urmărind să ofere un sprijin eficient culturii româneşti. În Bucureşti, Iaşi şi Cluj au luat fiinţă fundaţii şi aşezăminte regale consacrate menţinerii şi încurajării creaţiei culturale. În Bucureşti, fondul de carte al Bibliotecii Universitare „Carol I", devenită Biblioteca Centrală Universitară a făcut obiect de studiu pentru mulţi studenţi şi profesori, iar Editura Fundaţiei pentru Literatură şi Artă a dat la iveală cărţi valoroase pentru toate domeniile. Tot de numele acestei fundaţii se leagă şi apariţia unei publicaţii periodice care vreme de 13 ani s-a impus ca una dintre cele mai bune în contextul vieţii culturale bucureştene. La conducerea acestor aşezăminte regale au fost numite personalităţi recunoscute ale culturii româneşti care cunoşteau îndeaproape necesităţile acesteia şi au orientat cu competenţă activitatea fundaţiilor regale spre domenii care aveau nevoie de sprijin şi spre manifestări de reală valoare pentru cultura românească. Deschizătorul acestui drum a fost primul rege al României, Carol I. Cu ocazia împlinirii a 25 de ani de la venirea sa pe tron, regele Carol I şi-a exprimat dorinţa înfăptuirii unui aşezământ care să servească tinerimii universitare 1.Pentru construirea acestui aşezământ regele donează din patrimoniul Casei Regale o suprafaţă de teren de 1 200 mp', situată în faţa Palatului Regal, precum şi suma de 200 OOO lei 2. Fundaţia Universitatea „Carol I" a fost construită între anii 1891-1895. Biblioteca universitară „Carol I" a oferit studenţilor de la toate facultăţile un sprijin important în întocmirea lucrărilor de specialitate, tezelor de licenţă şi doctorat.
