Abstract
Natural observations and mathematical modeling of methane exhalation during increase of intensive mining in shallow coal seams have found that when excavation speed of coal area movement increases, process of methane desorption and its filter into atmosphere of working face is delayed. Discovered objective laws are subject to create scientific base to determine loading factor of highly productive working face, allowed as per gas ratio.
