Proceedings of the I International Conference "Underground Disasters: Models, Forecasts, Prevention" (30.) 09-03. 10. 2009. , Dnepropetrovsk, NSU). - s. 179-186. The idea of the leading role of mechanochemical representations in the formation of ejection-hazardous states in coals and rocks is considered. The results of quantum-mechanical calculations of the value of the chemical bond energy of chains under the influence of external physical fields and t. are presented. p. Estimates show that the stability of chains depends not only on the parameters of external physical influences, but also on the number of atoms in the chain.
