| Abstract: | Based on the basic principle of the similarity theory, this paper has analyzed compre-hensively the basic characteristics of methane migration and its ascension in gob air-flow, prelimi-narily approached the mechanics condition of methane ascension in stope and derived all the similarity norms that should befollowed in gob model experiment under time -independent condition and made experimental research on the problem of Methane Ascension Ascension in Gob, the result shows that methane with active source takes on ascension characteristic and ots buoyancy force shoulen't be overlooked. |
