Fire Mater 1981 Jun; 5(2):47-51
Characteristics of smoke particulates generated from a coal fire in a ventilated model tunnel were investigated by laser optical transmission and by electron microscopy. Average particle diameter and mass concentration of the smoke were determined as a function of the temperature and stoichiometry of the coal tunnel fire. Smoke particle sizes ranged from 0.2 to 0.9 Um, with larger particle sizes associated with higher smoke concentrations. These coal smoke data are relevant to several aspects of underground mine safety including the devlopment and location of smoke detection instruments, the understanding of the fire (toxic fume) hazards, and the development of new fire protection and control techniques.
