popup.description2
The model of a large-scale hierarchy of the structure of a metastable coal substance has been developed and terms of activating and passing of physical and chemical processes in coal at atom-molecular level have been established, the review of potential alternative ways and sources of obtaining the energy products and mineral raw material of unconventional type is executed, methodical bases of prognostication of natural and technogenic gas accumulations of carboniferous layer are developed. Geological principles of prognosis of outburst danger of sandstones and basic principles in preventions of the gaz-dynamic phenomenones (GDP) are formulated, according to which methodology of numeral simulation of geomechanical and filtration processes, which take place at application of the gas-dynamic phenomenones prevention methods in the coalface of the mine was developed taking into account mining and geological conditions of their realization for determination in effectiveness of GDP prevention methods. Recommendations concerning the determination of parameters for the hydraulic loosening of coal bed during realization of the experienced infusions for the decrease of its outburst danger.
