A characteristic feature of any tailings storage facility, unlike other types of engineering structures, is that all structural elements of the storage facility: pioneer dams (thrust prisms) and reclamation slopes - constitute a single flexible system, the reliability of operation of which depends little on the uneven development of deformations of its elements, because the technology of construction of the storage facility is a controlled process.
According to the conditions of occurrence, distribution and condition, it is the thickness of melomergel sediments in the deposits of the Kursk Magnetic Anomaly (KMA) that controls the quality of groundwater in the region.
