Conference paper


The article describes the complex technology of coal methane recovery, which involves underground coal gasification of lower beds in series of gas-rich strata liable to rock-bumps, coal based methane recovery and mechanized coal mining. Geodynamic zoning is used for selection of places for well drilling. The application of the suggested technology enables to solve a range of tasks, such as
  • unloading of workable beds and reduction of their rock-bump hazard due to protective seam burnout;

  • increase of workable beds degasification due to unloading;

  • increase of workable bed methane desorption rate due to conductive and partly convectional heat transfer through interbeds;

  • reduction of workable bed coal strength and rock-bump hazard by passing-through combustion gases (CO and especially CO2);

  • degasification of coal bearing layers and sublayers of interbeds due to their partial burnout during gasification and accelerated degassing during intensive heating;

  • increase of gasification products heat value due to their diluting with methane recovered from upper beds degasification;

  • reduction of methane outburst to the atmosphere, which has greater greenhouse effect in comparison to carbon dioxide.
