Abstract: On the basis of the oxygen lack circumstance of plateau of 4 200 m, the related parameters of oxygen enhancing ventilation desigen of blind drift are calculated. The process of oxygen enhancing ventilation at the condition of 30%~50% concertration of supling oxygen is simulated, and the amount of oxygen and the concentration is analyzed. The result provides data for the plan of enhancing oxygen ventilation in blind drift at plateau mine.
