摘要
根据热流体学理论，结合矿井火灾特点研究了矿井火灾燃烧区产生的热阻力，得出了倾斜（或垂直）巷道及水平巷道内火灾燃烧区热阻力系数的表达式，还给出了两种井下固体可燃物在水平巷道内燃烧时热阻力系数随无因次加热准则变化的实验结果。
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.
