BROWN COALS SAKHA REPUBLIC (YAKUTIA) IS A RAW MATERIAL FOR HUMIC SUBSTANCES

The resource base of the coal of the Sakha Republic (Yakutia) is considered. It is considered its progress in the development of the Far East and given the state of resources and the possibility of processing the brown coal to obtain the humic substances. For coals of the Sakha Republic (Yakutia) is also shown that the developed method for producing humic substances from brown coal (the developer of the method Institute of Mining of the North SB RAS) allows to obtain physiologically active humic substances in large quantities of humic acids yield.

Key words: lignite, coal reserves, humic substances.

STRUCTURAL AND MATERIAL HETEROGENEITY OF THE KEIVY BLOCK FROM GEOPHYSICAL DATA

Tectonic and structural, as well as time-and-space features of the Earth’s crust formation of the Keivy ore area accommodating a number of major deposits and ore occurrences have been considered. The structure of geophysical anomalies within the area has been defined; its relation with petrophysical properties of the rocks and staging of deformation and metamorphic processes has been identified. The results showed that the tectonic regimes and the nature of metamorphic processes could significantly affect the material composition, structure and commercial value of the Keivy block mineral deposits.

Key words: Keivy, Neoarchaean, Palaeoproterozoic, Baltic shield, geophysical fields, tectonic regimes, metamorphic processes.

INTERPRETATION OF SEISMIC TOMOGRAPHY FOR EXAMPLE STUDY THE GEOLOGICAL STRUCTURE OF THE LANDSLIDE SLOPE

The article discusses the basic techniques of data interpretation of near-surface seismic tomography in the study of landslide-prone slopes. In a specific example, analyzes a continuous distribution of velocities of primary and shear waves, Q-factor and anisotropy of seismic properties. The data obtained are features of the components of the landslide slope and geological boundaries, slip planes, blocks displaced or deformed rocks and groundwater levels.

Key words: near-surface seismic, interpretation, method of the refracted waves, seismic tomography, landslides.

RESERVE WATER SUPPLY SOURCES IN THE FORMATION AREAS OF THICK PERMAFROST ROCKS

Yakutsk diamantiferous province developed by AK ALROSA enterprises is located mainly in the areas of thick permafrost zone, in other words where fresh groundwater are either in solid state or in liquid state within small rivers and lakes. Consequently, the company’s enterprises and inhabited localities are supplied with potable water mainly from water storage reservoirs constructed on the rivers. However, at present time the planned amount of fresh water within storage reservoirs is insufficient drastically due to a sharp increase in leakage through subgelisol zones. And this problem is not caused by hydraulic engineers but technical solutions applied and justified by existing natural conditions in which these hydraulic facilities were located.

Key words: diamantiferous province, permafrost rocks, water storage reservoir, underground waters, hydraulic facilities, water supply.
