Thermodynamic calculation of air resistance in mine ventilation

NIU Guo-qing

Abstract：Engineering thermodynamic is used to deduce the calculating equation of air resistance in mine ventilation．Some factors that affect the accuracy of air resistance such as the change of interal energe of air，compression of air and heat exchange between air flow and mine are discussed．It is more perfect in theory，all parameters in the equation can be measured easily．Compraing with the conventional Bemoulli equation，the thermodynamic calculation is more correspondent to the reality．
