Ukraine is a country with vast coal reserves of all grades. The estimated coal
reserves in Ukraine are around 4% of the world coal reserves. We have three coal
basins located on the territory of Ukraine: Donetsk, Lviv-Volyn and Dniprovsky.
Donetsk coal basin is the largest of them. It contains 85% of all Ukrainian coal
resources. Not a secret to anyone that coal takes over 95% of Ukrainian energy
resources
