Abstract.

One of the most problematic issues in the field of explosion risk in the coal mines is coal dust deposits in the tunnels. Therefore, a problem of protecting tunnels against coal dust explosions when dust shoots up is a question of the day. Main problem of any theoretical study on the dust propagation in mines is how to calculate its shooting up and deposition, mainly on the bottom of tunnels. As a rule, too free assumptions on nature and mechanism of these processes lead to a qualitative discrepancy between theoretical results and results of observations. This article describes specifics of formation of the dust deposit along the length of the belt roadway. Proposed formulas allow calculating concentration and composition of the underground aerosols in the length and height of the mine tunnels in terms of gravitational and inertial particle deposition.

Keywords:

dust deposits, explosive risk, belt roadway.
