Energy Overview of Hungary GENI

There are only two black coal mines in Hungary; both are open pit mines and are located in the southern part of Hungary. Black coal in Hungary is difficult and expensive to mine because the seams are relatively thin and often steeply sloped. These coal seams also contain significant amounts of methane, which so far has proven difficult to extract economically for use as a fuel. The predominant
