Summary: | The presence of closed porosity in fossil coals is shown. The technique of definition of closed porosity is developed. Volumes of closed pores for coals of the various sorts are determined experimentally. It is established that the contribution of closed pores in total porosity in most cases exceeds 60%. The tendency of closed pore volume to increase in outburst-prone coals is found out. |
