Research and Development of Bio-Degasification Technologies for Coal Fields

Аннотация

The current situation and development trends in the biological degasification of coal are reviewed. It is shown that methane desorption is a consequence of rock mass destruction by activity of microorganisms and releasing bacterial metabolites. The influence of microorganisms on coal as a function of a prevailing microbial community and its variety, access of oxygen and nutritious substrates is observed. Advancement of the biological method for coal field degasification based on the methanotrophy is discussed.
