| Abstract: | Based on the theory of thermofluid dynamics and the characteristics of mine fire,the thermal drag in the combustion zone of mine fire is studied, and formulae of thermal drag coefficients for inclined (or vertical)and horizontal roadways are given. Finally, the experimental results of thermal drag coefficient variation with dimensionless heating number for two kinds of common solid combustible materials are presented. |
