Refined assessment of seismic microzonation with a priori data optimisation
- Authors:
- I. B. Movchan
- A. A. Yakovleva
The work is devoted to the issues of seismic microzonation representativeness, which is amongst the mandatory assessments that precedes civil and industrial construction. In addition to the practical approach and in accordance with the normative documentation, the authors propose parametric interpretation of the remote basis by means of tracing geodynamic zones and elements of the geoblock structure, where the leading marker of seismogenic risk zones is the anomaly of spatial variability of the geofield, coinciding with the discordant intersection of localised land structures. Verification of this marker is achieved by displaying a cartographic distribution image within the range of the seismic point increment, detailed on the basis of approximation dependencies.

The technology of extracting gaseous fuel based on comprehensive in situ gasification and coalbed degassing
The study considers a comprehensive technology (designed and patented by the authors) of developing coal and methane deposits which combines in situ gasification of lower coalbeds in the suite of rock bump hazardous gassy beds, extraction of coal methane and mechanized mining of coal. The first stage of the technology consists in mining gaseous fuel that enables one to extract up to 15-20 % of total energy from the suite of coalbeds. Geodynamic zoning is used to select positions for boring wells. Using the suggested technology makes it possible to solve a number of tasks simultaneously. First of all that is extracting gaseous fuel from the suite of coalbeds without running any mining works while retaining principal coalbeds in the suite and preparing them for future processing (unloading and degassing). During the first phase the methane-coal deposit works as a gas deposit only, the gas having two sources – extracted methane (which includes its locked forms, absorbed and adsorbed) and the products of partial incineration of thin coalbeds, riders and seams from thee suite. The second stage consists in deep degassing and unloading of coal beds which sharply reduces the hazards of methane explosion and rock bumps, thus increasing the productivity of mechanized coal mining. During the second stage coal is mined in long poles with the account of degassing and unloading of coal beds, plus the data on gas dynamic structure of coal rock massif.

G.V.Bogomolov and his role in development of national hydrogeology
- Authors:
- D. L. Ustyugov
- L. P. Norova
In March 2015 the scientific community celebrated the 110th anniversary of the birth of one of the founders of the hydrogeological and engineering-geological school, an honouree of State Award of the USSR and the Byelorussian SSR, Academician Gerasim Vasilyevich Bogomolov. The article is devoted to several important stages of the development of Russian hydrogeology, which are primarily associated with the research conducted by G.V.Bogomolov. His role in the development of hydrogeology in Belarus, i.e. theory and practice of the use of groundwater, is emphasized. This article is about the man who was a brilliant geologist, scholar, lecturer and an outstanding research manager. G.V.Bogomolov founded a school of disciples and followers who continued to develop and put into practice the academician’s ideas in various branches of geological theory and practice.

New data on infrared spectroscopy of diamonds from industrial deposits of Yakutia
- Authors:
- I. N. Bogush
- S. I. Mityukhin
- E. A. Vasiliev
Results of investigation of large diamond samples from main primary and some placer deposits of Yakutia by FTIR is given. Comparison of various characteristics indicates that maximal difference for samples of diamonds from different sources and minimal diversity for different samples from one source have average values of absorption coefficient and maximum positions of B2 absorption band. The revealed parameters are proposed to be used during comparative analysis of diamonds of different kimberlite pipes, determination of the initial source of placer diamonds, forecasting of new sources.
