Intra-permafrost waters

INTRA-PERMAFROST WATERS (EN: intrapermafrost waters; DE: Intraglazialgewasser; FR: eaux d'intrapermafrost; ES: aguas de intracongelacion; RU: внутримерзлотные воды) are the underground gravitational waters of the cryolitic zone, which are contained within the stratum of the permafrost rocks as the lenses, horizons, and other bodies with various shapes and sizes.

The intra-permafrost waters do not have the hydraulic communication with other types of the underground and superficial waters, and possess the limited static reserves. They distinguish the intra-permafrost waters, which are fresh with the positive or zero temperatures, and which are saline with the negative temperatures (the cryohaline waters, or cryopegs). The fresh waters are able to introduce themselves into the permafrost rocks, and, while freezing, to form the injected underground ices. The cryo-haline intra-permafrost waters, during the increasing of the temperature, partially dissolve the underground ice within the country rocks, and obtain the decreased layer pressure. During the penetration of the lenses of such waters using the drilling boreholes, there proceeds the intense devouring of the drilling fluid. During the winter time, the intra-permafrost waters form the aufeis, and thus are complicating the conducting of the mining works (for example, within the open-pit mines).
