Enhanced energy efficiency of ventilation in potash mines by means of sequential airing of service rooms

The carbon footprint reduction is becoming a key objective in coal mining. Accordingly, it is urgent to cut down energy consumption of production processes in mines. Many a studies in the sphere of mine ventilation aim to enhance energy efficiency of mine ventilation. One of the promising though understudied approaches to ventilation energy efficiency stimulation in mines is sequential airing of service rooms. In the proposed system of ventilation, the air flow after the service room airing is used to air the sequential operating spaces in this direction of the mine field. The field studies of gas distribution in a mine at the Upper Kama deposit of potassium and magnesium salts are described, and the modeling scenarios of sequential airing of service rooms in the mine are presented. The safety of the proposed technology and arrangements is theoretically confirmed. The economic indicators to рrove practicability of sequential airing of service rooms are given. The proposed approach enables burden reduction in operation of the main mine fan and air conditioning system.

Keywords: mine ventilation, sequential airing, carbon footprint, ventilation energy efficiency enhancement, potash mines, safety, toxic gases.
