At the territory of Kryvyi Rih, where from the end of the 20th century iron ore mining was
performed in the open way, and in the following decades by underground method, dozens of
decommissioned dumps and those in which the overburden rock is continuously backfilled are
concentrated in a small area. The area of the largest dumps is close to 1000 hectares and their
height to 100 m, these dumps create serious environmental problems for the region as dust blown
from their surface spreads to residential areas of settlements
