PRESENT STATE OF ORE MINING IN SLOVAK REPUBLIC
Abstract
The article briefly describes the present state of ore mining in Slovakia and describes some technological aspects of mining and exploitation of two selected deposits. The first is the gold and silver deposit in Banská Hodruša (located in the central part of Slovakia - the historically very important region of gold mining) and second is the iron (siderite) deposit in Nižná Slaná-Kobeliarovo (located in eastern part of the country). At the present time, the deposits belong to the key mining facilities of the Slovak mining industry. The Svätozár gold deposit at Banská Hodruša is in the Bansko-Hodrušský ore district and the Mano-Gabriela iron deposit is in the Spišsko-Gemerský ore district. The area of perspective extraction of gold and silver is also the deposit of tetrahedrite ore of the Silver vein (Mária Baňa mine) in Rožňava. In the paper, some technical aspects of the gold and iron mining at the mining works - ŽB Spišská Nová Ves, enterprise SIDERIT and the SLOVENSKA BANSKA Ltd. Mines in Hodruša are further described. One part of the paper deals with the mining method and the technology at both mining enterprises. The results of mining and exploitation of the deposits by block-caving are presented. The so-called "Gold programme", which is presently realized in Slovakia, supposing a transformation of the ore mining to the mining of precious metals, is shortly described.
