Research on mensuration method of ventilation equipment external air leakage
Abstract：It is one of signify indexes to evaluate running status of main fan and mine ventilation management level for external air leakage ratio, and the selection of mensuration methods is the chief issue for technique personnel when mensurating external air leakage. In term of coal mine ventilation theory, those characteristics were analyzed for various mensuration methods such as the principle, process, and applying condition. As a example of external air leakage mensuration of wugou mine, the gist and process of selecting mensuration methods was discussed. The resuh showed that mine external air leakage ratio was 8.4% and 7. 85% re- spectively corresponding 1^ # fan and 2^# fan running, equipment air leakage of spare fan was the most primary air leakage fountain- head, so specific measures must be applied to reduce air leakage. The research conclusion will provide scientific field reference for eliminating air leakage hidden trouble and optimizing mine ventilation system.
