Nitrogen and carbon dioxide occurrence in UK coal seams
Conclusions Some bituminous coals, mostly of high volatile rank, sampled from various coalfields contained on average 0.5 $ m^{3} $ $ t^{−1} $ nitrogen and 0.13 $ m^{3} $ $ t^{−1} $. Nitrogen is released more readily than methane during coal winning but the volumes of nitrogen released are small compared with ventilation quantities and are only likely to be of significance for detailed oxygen deficiency studies.
