The article analyzes possibility of dust burden decline in conveyorway by means of increase of efficiency of equipment of aspirating shelters. For substantiation of parameters of the aspirating shelter the detailed analysis of exchange of air in shelter of transfer junction of two conveyors is executed. As a result of the experimental data mathematical processing the lines of air stream are built and conformities to the law of air speed change at the entrance of an aspirating chamber are ascertained subject to the distance from the conveyor belt and for different mountain mass moving speeds. On the basis of the researches the method of calculation of aspirating shelter allowing account taking of the dynamics of moving mountain mass and its influence on the streams of aspirated air is developed.
