摘要
探讨局部阻力功和正面阻力功对矿井热力计算的影响。论文首先对常用矿井热力计算基本理论做简单概述;之后从热力学第一定律开始探讨矿井沿程阻力对矿井热力计算的影响;最后在以上两方面工作基础上,探讨局部阻力和正面阻力对矿井的热力影响,并最终对矿井热力计算理论作局部补充,得到适用于局部阻力和正面阻力较大井巷的矿井热力计算公式。
The effect of local resistance and head resistance on mine＇ s thermal calculation is presented in this paper.Firstly,the principal theory of mine＇ s thermal calculation is summarized;secondly,the effect of on-way resistance on mine＇ s thermal calculation started from the first law of thermodynamics is discussed;finally,the effect of local resistance and head resistance on mine＇ s thermal calculation is discussed based on the above mentioned two works,and then it made the partial complement of the mine＇ s thermal calculation theory,and it got the mine＇ s thermal calculation formula which is suitable for the mine with large local resistance and head resistance.
