Grigore BUIA, Csaba LORINŢDepozite de huilă din RomâniaHard Coal Deposits in RomaniaThis paper started from some observations made on the world’s coal production, as compared to our national production. Considering this document, this paper means to summarize and describe from a geological point of view hard coal deposits in the Romanian substratum, in order to study the possibilities to extend the leased areas.

Roland MORARU, Gabriel BĂBUŢModul de interpretare a deficienţei în oxigen din componenţa indicilor de apreciere a evoluţiei combustiilor spontaneOxygen Deficiencies Interpretation for Use in Ratios Assessing Spontaneous Combustion ActivitySeveral common ratios used for determining spontaneous combustion activity rely on comparing the amount of various products of oxidation with the amount of oxygen consumed to produce these products. As coal gets hotter, oxidation reactions become more efficient meaning more products produced for less oxygen consumed. There are many problems associated with accurately determining the true amount of oxygen used. These problems relate to the monitoring technique (and its associated uncertainties) used to generate the results, deficiencies in the established equations utilized in calculations, dilution with other gases and other sources of oxygen depletion. Typically the oxygen deficiency is over estimated, resulting in the under estimation of the indicating ratio. This paper outlines problems associated with the monitoring techniques and equations used to determine the oxygen deficiency.

Ioan BUD, Simona Silvia DUMAÎnchiderea minelor în România. Amenajarea haldelor de sterilClosing Mines in Romania. Tailing Dumps RehabilitationThe paper analyzes in Romania the tailing dams rehabilitation process, specially in ore mining perimeters regarding design, execution and negative environmental impact and, in the same time, financial waste already visible. A very grave aspect is the fact that all activities have had administrative and governmental acceptation. The elaboration of a design and execution database at national level would offer the opportunity to adapt continuously the projects to local and regional specific.

Gabriela DUMBRAVĂElemente de folclor mineresc: credinţe, superstiţii şi tabuuri legate de Vâlva Băii - duhul minelor din Transilvania

Mining Folklore: Beliefs, Superstitions and Taboos Related to Vâlva Băii - The Fairy of Transylvanian MinesThe paper is an attempt to approach occupational folklore from an anthropological - philosophical perspective, regarding it as a set of beliefs and rituals occurring at the convergence between people’s fear of the unknown and their need to permanently negotiate their relation with it. As a concrete example, we have chosen the system of beliefs, magic rituals and taboos related to a fantastic creature known as Vâlva Baii, or the fairy of the mines, a dual character that embodies the ambivalence of the mine as a mysterious realm of treasures and disasters, and, ultimately, the ambiguity of the miners’ feelings towards this space that fosters life and death at the same time.
