Abstract

In order to determine the leakage location and leakage size in the gas extraction pipeline, the study establishes the gas running state mathematical model of the gas extraction pipe network, and the evaluation model of the leakage state and leakage severity on this basis are set up. After field test in Songzao mining area, the experimental result shows that the model can meet the needs of leakage automatic detection in the gas extraction pipe network.
- gas extraction,
- gas extraction pipe network,
