Inventory of mineral resources

The Hungarian Office for Mining and Geology keeps the records of mineral resources and reserves of Hungary pursuant to provisions of the multiple amended Section 25. of Act No. XLVIII. of 1993. on mining as well as Government decree No. 203/1998. for its implementation .
 
Balance-like registry of national mineral raw materials is based on the obligatory data delivery from mining entrepreneurs as well as the resolutions issued by the concerned County Government Offices (the Division of Mining Supervision and four Departments of Mining of Divisions for Authority Affairs). The registered types of minerals are the following:   

  • hydrocarbons (crude oil, natural gas, carbon dioxide),
  • coals (black, brown coal, lignite),
  • ores (manganese ore, iron ore, lead-zinc ore, copper ore, precious metal ores, uranium ore),
  • bauxite,
  • non-metallic mineral resources,
  • geothermal energy.

MINERAL RESOURCES OF HUNGARY AS OF 1 JANUARY, 2017

 

The Hungarian Office for Mining and Geology keeps the records of mineral resources and reserves of Hungary pursuant to provisions of the multiple amended Section 25. of Act No. XLVIII. of 1993. on mining as well as Government decree No. 203/1998. for its implementation .
According to the present Act, mineral raw materials of Hungary in their natural occurrence shall be state property. Such treasures form a part of natural resources and national assets of our country, keeping records of them has been on by the Hungarian Office for Mining and Geology and its predecessors since 1953.
 
Balance-like registry of national mineral raw materials is based on the obligatory data delivery from mining entrepreneurs as well as the resolutions issued by the concerned County Government Offices (the Division of Mining Supervision and four Departments of Mining of Divisions for Authority Affairs). Raw data of the registry are the following:
 
 
•    quality and quantity of mineral resources and reserves;
•    annual change in mineral resources, reserves (production, exploration, reclassification, etc.) according to annual delivery;
•    mineral resource, reserve left behind subsequent to mine closure, field abandonment.


 
Based on such available data, mineral resources and reserves are recorded separately by each raw material including occurrence(s).
The National Registry on Mineral Raw Materials and Geothermal Resources consists of more than 4,000 registered mining areas. Both resources and reserves as of 1 January 2017. as well as production of Hungary in 2016. are presented in the following table.

The total coal production (black and brown coal, lignite)  of Hungary changed slightly in the past few years. Black coal production is negligible while brown coal production constantly decreased in recent years. Lignite production was slightly increased. There are coal production data from 2015 and 2016 in Table 3., production of the past few years in Figure 1.

Hydrocarbon and CO2

 

As for the registered 311 crude oil and natural gas mining sites, all changes in mineral resources, reserves in 2016 are due to the activity of 21 mining entrepreneurs.


Practically, data of non-conventional crude oil as well as natural gas concerning resources, reserves were constant.


As for the 1% decrease in geologic resource concerning conventional crude oil, it was due to exploration, which also over-compensated the combined effect of the exploitation and the negative resource correction 15 times its volume. Exploitable reserve decreased by 9% due to mainly the negative resource correction, which over-compensated the combined effect of exploration and production analysis five times more in absolute terms than the exploitation.
As for conventional natural gas, registered resource data increased by 4%, while reserve data by 9.6% due to mainly correction. 
Both geologic resource and exploitable reserve decreased concerning carbon dioxide resulted entirely by the decrease in production. The decrease was 0.4% taking the base number of the exploitable reserve.


Geologic resources of hydrocarbons and carbon dioxide of Hungary are shown in Table 4.

Geothermal energy

 

Geothermal energy is a plus heat quantity stored in geologic formations as a result of their higher temperature as compared to the superficial average temperature. In Hungary the value of geothermal gradient is 5  o C/100 m on average which is one-and-the-half times higher as the world average.  The superficial average temperature is about 11  o C. Considering the before-mentioned geothermal gradient, the temperature of rocks in 1 km depth is 60  o C, in 2 km depth is 110  o C, together with waters stored within. The reason is that the Earth's crust in the Pannonian basin is thinner than the world average (24-26 km thick, approx. 1-15 km thinner than other areas). Thus the hot mantle is closer to the surface. The reason is that the Earth's crust is thinner in the Pannonian basin (24-26 km, 10-15 km thinner as compared to other areas) than the world average, thus the hot mantle is closer to the surface. The measured thermal flow values are also one-and-the-half times higher (90,4 mW/m 2 ) as the European average (60 mW/m 2  ). Geothermal gradients are higher on the southern part of Transdanubia and the Hungarian Great Plain than the national average, while the lowest on the north-western part of Hungary and the mountainous areas.


Pursuant to Government decree No. 54/2008.: ”Geothermal energy: The inner thermal energy of Earth's crust which can be utilized for energetic purposes. Geothermal energy is recovered by either the transfer of fluids or gases above 30 o C (geothermal fuels), direct exploitation of such fuels or recirculation." 
The exploited volume and recovered energy in total reported to the Department of Mining and Royalty Income Affairs of the Mining and Geological Survey of Hungary are as follows: 
 
Exploited volume : 30,080,144 m3
Recovered energy : 3,280,999 GJ
 
The National Registry of Mineral Raw Materials and Geothermal Resources also keeps records of geothermal resource/reserve, geothermal protective pillars, facilities utilizing geothermal energy as well as volume of exploited and utilized geothermal energy. Some data of  the borehole database (facility identifier /rokarec/ and EOV coordinates /RX, RY/) were added to the records on facilities in 2016. The completion of registries - exept geothermal energy reserve - was done for 2010-2016. based on data sheets submitted by the licensees utilizing geothermal energy.
 
Exploited energy for other purposes (non-mining royalty) for 2010-2016: 34,052,743 GJ
 
Utilized energy for other purposes for 2010-2016: 10,661,108 GJ

 

 

Waste rock/waste 


 
Upon an obligation from the European Union, there is an obligation for servicing data pursuant to paragraph (3) of Section 14 of Ministerial decree No. 14/2008. on mining wastes in case of any change in mining waste. So we started to register all data in 2009. referring to any changes either in volume or in quality.
At request, mining entrepreneurs - in the frame of annual data delivery - submit data on waste rock and waste generated in the reference year, sorting them in different groups.
