Essay

The analysis of vent systems and state of ventilation of manganese mines is executed in the dissertation work. It is concluded, that the basic lack of vent systems of manganese mines is considerable unproductive losses of air in the network of the underground openings and through surface buildings and vent buildings on a ground complex. The conformities law of air consumption is set, depending on the length of the parallel openings with the reverse air stream. The process modeling of energy consumptions is conducted, related with moving of air outwards of the networks of the openings on the base of which the aerodynamic parameters of vent buildings are grounded and the area of the effective use of elements of a mine vent network is con-ducted. The mathematical model of process of co-operation of counter-flows of air streams in the stream aerodynamic systems is developed, that allows to define their optimal parameters and rational arrangement of elements to increase the efficiency of work in the field of low pressure differential. Criteria are offered and grounded for the estimation of efficiency of work of the counter-flow aerodynamic system.
