Possible nature of anomalous conductivity of DDD and Donbass is considered. The detailed description of materials concerning the earthquakes of Novodar and Roven is represented. The author makes an assumption that presence of graphite skins and formation of fractured porous massifs in rocks can be one of the possible trigger mechanisms.
Geology-geophysical conditions of Kryvyy Rig earthquakes region are considered in limited by co-ordinates φ=47,45÷48,60 N and λ=32,5÷34,150 E area. Detailed description of materials of earthquake of the 14th of January 2011 is given. Author does supposition that presence there of graphite skins and formation of fractured-porous arrays in rocky breeds can be one of possible trigger mechanisms for local earthquakes.
Regularities of changes in solid fuel elemental composition during metamorphism have been investigated. A mathematical model describing these regularities as functions of Cdaf has been developed. Experimental data of artificial coalification confirm that it is an experimental model of natural metamorphism.
Dynamics of coal chemical structure during metamorphism has been evaluated using mathematical model of metamorphism kinetics attached to the time axis in accordance with artificial coalification data.
“Jumps” in structure composition and properties of solid fuel have been determined using the model of metamorphism dynamics. For these “moments” of the geological age the elemental composition and structural peculiarities of “molecules” have been determined and approved by stoichiometric equations of the reactions, material balances of the stages and the agreement between the combustion heat of model compounds and coals of similar elemental composition.
The research works dedicated to the formation regularities of solid fuels chemical structure were analyzed. Modern conceptions of coals chemical structure, which are becoming deeper owing to tooling growth and facts accumulation, were examined by means of critical comparison of different hypothetical models of solid fuels “molecular” structure. The most general points of the respective theories were formulated, according to which “soft” influence on coal structure primary elements bonds system allows bringing its chemical potential to the maximum.
