Change of the maintenance and structure of residual hydrocarbons of minerals coals at emission of hydrocarbons from coal in an atmosphere
Residual hydrocarbons long time (years) are kept in taken of a layer coa, but their maintenance and structure can change as a result at emission of hydrocarbons from coal in an atmosphere. Supervision over residual hydrocarbons of coal К-5 (layer К-5, coal of mark Ж, Kuzbass) has shown that for 9 years in a corner the maintenance an residual hydrocarbons in 2 times has decreased and the structure of hydrocarbons has changed - the attitude(relation prophane/buthane has decreased from 0,5 up to 0,2. The structure of the hydrocarbons allocated from coal in an atmosphere - prophane 70,5 % and buthane 29,5 % (in the sum of hydrocarbons).
