CHINA MINE ENGINEERING

Based on the problems of poor ventilation conditions in Sareke copper mine, single wing ventilation and double wing ventilation are adopted, check the total air volume from four aspects, the control of ventilation system is studied. The results show that no short circuit, air leakage, turbulence, stagnation, cross flow and reverse flow are found, the design of the ventilation system is simple, which ensures that the mine underground operators have a good working environment, can breathe fresh air, reduce the toxic and harmful gases and dust hazards produced by truck exhaust and gun smoke, and ensure the safe and efficient production of the mine.
