摘要：According to the characteristics of the high steep coal seam mining with false-inclined flexible shield support method such as high tunneling ration, multi air leakage channels and easy spontaneous combustion, the technology of multi-element tracer gas was proposed to measure ventilation leakage in the goaf. With its application in the No.13111 working face of a certain mine in the Huainan Mining Group, the realization methods were described in detail. This technology is advantageous to the improvement of scientific and accurate detection of the air leakage in the complicated goaf. It may be stated that the method can master the division of air leakage areas and provide the scientific references to the prevention and control of the coal spontaneous combustion in the goaf.
