Developments & Scientific Achievements
In the process of fundamental scientific research, the theoretical basis for the use of in-mine geophysics and methods of mathematical modeling of the distribution of physical fields in coal-rock mass are developed; technical and methodological developments related to improvement in in-mine geophysical equipment and further improvement in mine geophysics methodology are accomplished.
For the first time the methodology of geological and geophysical prediction of methane reservoirs based on the principles of coal petrophysics and patterns of lithological variability of the object of study was created for coal deposits.
The developed methodology allows by physical properties of rock mass determined by employing methods of exploration geophysics to identify places of local improvement of the quality of reservoir units and on this basis to design the sites and path of CBM horizontal wells with the maximum delivery of methane.
Also for the first time "Guidelines for assessing the gas content of coal-bearing strata of Donbass on the basis of the formation analysis" have been developed and published for mobile and low-cost determination of quantitative indicators of natural methane presence of coal seams and host rocks at depths of more than 1000 m without the need for additional drilling of exploration wells.
2D, 2.5 D and 3D seismic, geoelectric and geoinformation models of the geological environment for the conditions of landslide areas of seismic regions of the coast of the Azov Sea and the Black Sea were developed for the first time within the framework of applied topics. In order to significantly improve the efficiency of 3D seismic survey in predicting the conditions of mining of coal seams and industrial gas production, the software for 3D-modeling of the propagation of seismic vibrations in the coal mass has been developed. Prototype of mine seismograph СШ12К was developed.
Research and development work in the frameworks of the innovative projects has resulted in a prototype of seismic hardware and analytical complex ААК12 and production prototype of in-mine analyzer of electromagnetic pulses ШАИ-8 designed to detect sections of coal-rock mass potentially prone to gas-dynamic phenomena. Both developments are allowed to operate in mines prone to coal, gas and rock outbursts. On the basis of ШАИ-8 ReMi-method-based equipment was manufactured in factory environment, the use of which is provided by the well-known system УТАС (a standardized telecommunication automated system).
Complex methods and original developments of the department were used in research in mines and coal mining companies in Donbass, Russia and Kazakhstan, at landslide areas of Crimea, Azov and Black sea coasts, as well as at such large engineering facilities as Ingulets Mining and Processing Plant (GOK), Salt Mine in Solotvyno, railway bridge over the Amu-Darya river in Turkmenistan, Russia-Turkey gas pipeline, Eastern Siberia–Pacific ocean oil pipeline, Olympic facilities in Sochi.
The staff of the department has more than 700 publications of scientific articles, including about 50 registered copyright certificates for inventions and patents for utility models.
Methods, Equipment and Software Used:
- The basic method when conducting land and underground geophysical surveying is CDP seismic survey, correlation refraction shooting and seismic imaging (in-seam seismic survey). At the same time it is possible to use 3D-technologies
- For the solution of specific range of tasks in combination with seismic survey or all alone the employees use resistivity prospecting (VES, electrical profiling (EP) and other methods); near-field transient [time-domain] electromagnetic sounding and transient electromagnetic method (transmitting loop sweeping at the surface over the distance of up to 1.0 km and transmission distance in this case is 1.0 – 2.0 km); the Earth’s natural pulsed electromagnetic field method (ENPEMF) to assess the geodynamic state of rock mass.
- For conducting field and underground research, modern geophysical equipment is used:
- seismograph at the base of the Geode modules: 6 modules 24 channels for 3D seismic survey (Geometrics, USA);
- seismograph "Lakkolit-24" (Russia, Zhukovsky, Moscow region);
- electrical exploration station “ERA-MAX " for resistance research (Russia, St. Petersburg);
- electrical exploration station “ERA-MAX " for resistivity survey (Russia, St. Petersburg);
- “Impulse-D” electrical exploration equipment for pulse induction electrical exploration by near-field transient electromagnetic sounding-transient response methods (Russia, Novosibirsk).
Underground survey in gas- and dust-hazardous mines is made using specialized explosion-proof equipment and instruments designed in RANIMI (mine seismographs СШ-12К and ААК12, mine pulse analyzer XAI-8, mine electrical station ШЭРС-5М, etc.).
- Licensed software is used for data processing, including:
- RadExPro seismic processing software. It is well suited for in-depth HR/UHR marine seismic processing, real-time marine 2D/3D seismic QC, onboard fast track processing, land and marine off–line seismic QC, complete processing of near–surface seismic data (reflection, refraction, tomography, MASW) and VSP processing;
- SPW3 Engineering package for 3D seismic data processing land and marine surveys performed on special equipment;
- Ipi2win for one-dimensional interpretation of VES data;
- Autodesk Autocad for creation of applications with the results of geophysical survey for the reports of the department; the use of topographic maps and subsurface maps for the binding interpretation results.
RANIMI Institute is engaged in underground geophysical surveying since 1973, when in-mine geophysics division was established, which has become the leader in this area of work. Since 2002 scientific-methodical and experimental research in the field of prediction of mining-geological conditions for working of coal seams employing geophysical methods are carried out by the department of ecological and geophysical research. Altogether, more than 250 mine working areas (blocks) in Donbass, Ukraine, Russia and Kazakhstan have been surveyed that allowed improving the efficiency and safety of mining operations. Reliability of predictions is 85-90 %.
Land geophysical survey carried out by the Institute, which is also a priority of scientific and methodological activities of the OEGI, has been intensively developed since the early 1980-s of the last century. Efficiency of the survey, aimed primarily at the safety of mining operations, scientific and technical support of mining and ensuring technological safety of constructed and operated facilities, is based on their complexity (seismic, electrical, magnetic, gravity, emanation survey, etc.), as well as the use of modern 2D|3D geological and geophysical technologies. More than 500 objects on the territory of the republics of the former Soviet Union were investigated.
Over the past 10-15 years, based on the instruments and equipment available in the OEGI, and on the basis of studying the experience of modern geophysical instrumentation, the development of in-mine geophysical equipment has been rapidly developed.
