A coal mine might become a complex ventilation network to influence the stability and the reliability of the mine ventilation system when some large air-leakages exist in the underground coal mine. If the air leakage passage is connected with a fire area, the very serious results will be brought about. The air leakage of the 9211 airway in the Beizu mine shaft is measured by using the method of the continuous and quantitative releasing of SF6, and the air flow leaking into the 9211 air way can quantitatively determined. The amount of the air leakage is calculated by determining the shortest distance of the detection, the detection time, the release volume and other air leakage determination parameters, according to the change of the concentration of SF6 gas. Two air leakage areas in the 9211 air way are detected, to provide a foundation to take corresponding measures of prevention and control of the mine air leakage, and the technical support to the mine fire prevention.
