It is an important medieval industrial and cultural heritage, which has never been protected before and we don’t really know its real size and condition. Within the framework of a PHARE CBC project the University of Miskolc and Technical University Kosice made a study about the environmental impact of ore mining and worked out a plan for the educational and tourist utilization of the area.

Earlier, that was the largest hard coal complex in Hungary with three historic mine complexes. Their production was continuous from 1782 until 2003. Significant undeveloped resources (amounting to 980 million tons) are still registered in the area. The coal-bearing sequence is of Lower Jurassic age, 120 to 1000 m thick, with 36 coal seams in three seam-groups. The coal is highly volatile A bituminous rank with high ash, medium-high sulfur content and with low permeability. After several serious gas outbursts the pre-mining gas drainage has become a routine prevention measure since 1970. The specific methane gas yield during mine production (cu.m per ton of extracted coal) has shown a systematic increase with depth, from 15 to 80 cu.m/ton, averaging on 50 cu.m per ton. The estimated gas resource in-place is 142.5 Bn cu.m. With an expected 0.2 recovery factor the potenti...

The deposit lies inside a Neogene sinistral strike-slip fault zone (Darnó Zone), bordered by master faults. The ore bodies are dissected blocks in a stack of horses structure. Iron, copper and lead ore resources were previously explored and mined in the area. During a recent exploration program additional zones of zinc and lead ores have been discovered representing two genetic types. The first one is stratiform, bound to reductive facies pelitic siliciclastic rocks. The second one is a hydrothermal mineralization, controlled by faults and siderite block boundaries. Both types have similar mineral paragenesis: sphalerite, galena, pyrite, barite. The two parageneses are distinguishable through their textural and geochemical fingerprints. Hydrothermal sphalerites show ...
