Abstract

The paper discusses a methodical approach to
evaluation a vertical flow of tailing dust mass. The
approach is based on the «DEAD» scheme and
processing numerical modeling results of aerodynamic parameters of the two-dimensional 2D
CFD-model “ANOF-2 tailing - Apatity region” at
the maximum designed height of the tailing. Dusting intensity values have been obtained at wind velocity variation on reference height 10 m in the 5 –
23 m/sec interval. The calculated value of dusting
intensity at 0,6 m/sec friction velocity corresponds
to a value of maximum dust blowing used by specialists of “Mechanobr Engineering” CJSC in the
tailing reconstruction project up to a maximum
height level.
