In order to perfect the current index equivalent orifice for assessment of coal mine ventilation capability checking, we put forward a new evaluation methodology to accomplish this aim based on existing research and the present practical conditions in China. In addition, indexes for calculating reasonable values of equivalent orifice for all kinds of mine ventilation systems are given. The new way is more reasonable and scientific by example. Equivalent orifice equation is analyzed and then it can be found that for the mines with different ventilation systems the calculation methods of total equivalent orifice and total windage are different. Equivalent orifice calculation needs the total amount of the return air in the mine; total windage is calculated according to the specific form of ventilation.
Key words: Assessment index, equivalent orifice of coalmine, mine ventilation, , , ,
