Abstract
Results of researches of the longwall face length influence on gas emission at the coal seam «Chetverty» longwall panels of the OJSC «Vorkutaugol» mines are given. Dependences of the longwall production and longwall face length are specified. Range of rational values of the longwall face length according to the gas emission control efficiency is determined.
