It is well known that the correct calculation methods of required air quantity for the working faces in underground mine are very significant to achieve a rational nine ventilation system. From 1979 to 1986, the calculation methods of required air quantity for diluting the dust, blast fume, diesel exhausl, heat and moisture in the drift-shape stope with through-flow were thoroughly studied based on different types of experimental models and thousands of experiments. According to the insitu measurement in seven metallic mines, the investigated results are well coincident with the field measured data. In this paper, the main achieved conclusions and several empiric formulas are presented merely because of the limited space of coverage of an article.
