Department of problems of geotechnology of combustible minerals
A head of the department: D. Sc. Stefanyk Y.
Basic research of D. Sc., professor, Honored Scientist Emmanuil Bohdanovych Chekaluk became scientific grounds of the departments foundation. The department of problems of deep-seated hydrocarbons, organized by him became the leading centre in the problem of inorganic origin of oil not only in the former USSR, but in the whole world. Works of professor Chekaluk E. B. on geotechnology of oil production, the process of extraction of residual deposits became a handbook of the most generation of oil-industry workers up to the present.
There are 14 employees working at the department of problems of geotechnology of combustible minerals, among their number are 2 Doctors of Science, 2 Candidates of Science, 10 engineering-technical workers: geologist, chemist, physicist, mathematicians.
The mains directions of scientific researches:
- geotechnology of extraction of fuel-power resources from non-conditioned fuels;
- intensification of oil influx from collimated wells;
- underground gasification of non-conditioned, thin , with low grade coal, deep-seated, variegated coal seams;
- gasification of coal dumps with the pourpose of obtaining power gas.
Conception of obtaining of rare synthetic products from processing waste (low-grade coal, biomass, oil-processing waste etc.) -was created.
The complex of geological criteria of suitability of coal beds for underground gasification was established based on the example of the Lviv-Volyn basin.
Thermodynamic conditions of the formation of oil-like system in the bowels of the Earth were established based on the isotope composition of carbon.
The “Working project of research-commercial polygon on biogas diversion” was developed for the Lviv polygon of solid domestic waste.
Feasibility study “Creation of additional productive zones at the existing Lviv municipal waste landfill at the expense of rehabilitation of tar collectors” was developed.
Integrated assessment of sanitary conditions in soil of the territory of the polygon of solid domestic waste of the Stryi-Drogobych region was given.
An appreciation was given for the suitability of the area for building of the enterprise for industrial waste processing with output of 100 th ton per year for the towns of Chervonorad, Sosnivka and the settlement of Hirnyk (Lviv Region).
Proposals were developed for the Programme of co-operation between the National Academy of Sciences of Ukraine and the Lviv Regional Council on the theme “To inculcate the technologies of the control over domestic waste and rehabilitation of the Lviv sanitary waste landfill and releasing of collectors of acid tars using energetic landfill gas”.
Technology of the biogas obtaining was introduced at the Lviv sanitary waste landfill.
Scientific co-operation with the Institute of Oil and Gas (Cracow, Poland) within, the framework of the program of friendly relations INTERREG IIIA, 2006-2007, developed into the theme in common: “Ukrainian-Polish centre of co-operation in gas control at the sanitary waste landfills”.
At present efforts of the employees of the department are directed to the development of geotechnology for obtaining lignin synthetic fuels and high-energy gas from non-conditioned deposits of the Lviv-Volyn coal basin. The department has an experimental installation modelling the processes of underground gasification of coal, obtaining synthetic-gas CO and H2 and synthetic oil-like hydrocarbons.
For the last seven years the employees of the department have published 185 papers, have taken out 29 patents of Ukraine for an invention for a candidate’s degree.
Preparation of young scientific personnel is realized both trough the post-graduate course and trough the institute of competition.
The department carries out a great amount of patent-licence work that is proved by the awarding of prize-winning places during the last seven years. In 2004 Yu. Stefanyk awarded the rank “The best inventor of National Academy of Sciences of Ukraine”.
