Experiment in firedamp drainage from retreating longwall face at Horden Colliery
Results of series of experiments on extraction of firedamp from longwall retreating face, which formed isolated goaf; effectiveness of removing gas from vicinity of working area by application of inclined borehole drainage with and without mechanical exhauster, and ventilation of goaf by establishing drainage roadway. (See also - discussion p 382-8)
