    Detection Technology of Goaf Air Leakage in Shallow Buried Depth Fully Mechanized Caving Face

    • The paper has analyzed the features of goaf air leakage in shallow buried depth fully mechanized caving face. Taking 6202 working face of Yangwangou Mine as air leakage passage detecting objection, and air leakage velocity and volume is detected by using SF6 as tracer gas, and the amount of air leakage is measured.
