Abstract

The aerothermodynamic parameters of air are studied in shafts of mines of NorNickel’s Polar Division. The total pressure and temperature measurements, as well as the air density calculations in KS-2, GS and VC-4 shafts in Oktyabrsky Mine show the linear total pressure dependence on the shaft depth and the essentially nonlinear dependence of air temperature and density on the depth of shafts at intersections with ventilation channels and horizons. The lengths of sections of leveling of air parameters behind the intersections are estimated. The authors propose a new method to determine aerodynamic drag coefficients in mine shafts and calculate ADC for 28 mine shafts in the Norilsk Region. The calculation results are used in mathematical modeling of mine ventilation networks and in ventilation designs for new mine sites.
