Purpose. Emissions from mine ventilation system can create intensive atmosphere air pollution. As a rule, a huge amount of dust from mine fan enters atmosphere low layers. An important task is the development of meth-ods to assess levels of the atmosphere pollution near mines and settlements. To solve this problem it is important to have physically...

... when the meteorological situation changes, the position of the pollution zones will change, but these territories will fall to some extent into the pollution radius. Figure 3 shows the concentration distribution at 1.7 m, which corresponds to the position of the human respiratory system. As can be seen from this figure, if we take MPCdust = 10mg/m 3 , then at a distance of 300m there is a violation of the MPC. ...

A computational model to simulate ventilation of a dead-end mine working with line brattice has been developed. To solve fluid dynamics problem, i.e. to compute flow pattern, model of inviscid flow has been used. That allows to compute quickly air flow pattern. To simulate dust dispersion in the dead-end mine working with brattice twodimensional equation of mass transfer has been used. Numerical integration of Laplas equation for the velocity potential has been carried out using Samarski two steps difference scheme of splitting. Proposed CFD model allows quick computing of dust dispersion in the dead-end mine working with brattice. Markers (porosity technique) have been used to create the complex geometrical form of computational domain. Results of numerical experiments which had been performed on the basis of the developed CFD model have been presented.
