APPLICATION OF AN AIR CURTAIN TO IMPROVE AIRFLOW CONTROL IN THE AIR TRANSMISSION SHAFT OF THE GUZHUMSOY MINE

Abstract

On the extraction of gold-bearing ores in mines, the amount of air in the ventilation network of mines increases in proportion to increases in the length of excavations and deepening of the mines. The article deals with issues of managing the air fl ows into mines, the use of air curtains to reduce external and internal losses to the mine, and aerodynamic resistance. The work describes the use of the main fan and an optimal ventilation scheme in order to increase the effi ciency of ventilation in mines with complex ventilation systems, with the view to reducing outdoor air losses in the ventilation duct and ventilation network by determining the optimal values for air fl ow, air fl ow rates, and pressure changes with ventilation parameters to ensure ways of eff ective control and distribution of the air fl ow
