摘要
本文从对高温采面热力参数实测入手,分析了采面重要热源采空区热风的分布及变化规律,求解了在采空区热风影响下的不稳定换热系数Kτ与当量氧化散热系数qox,从而可以比较准确地计算来面热源的总散热量。
By means of deducing and regressing from measured data obtaining from the typical thermal workingface at Sanhejian Coal Mine, the regularity of heat flow through broken rock has been found. The unsteady heat transfer coefficient (between country rock and air flow) and the coefficient equivalent of exothermic oxidation reaction have been corrected The method to calculate the heat dissipating capacity has been provided.
