Abstract The overlying strata movement and mining-induced fracture′s dynamic development are the main reason of causing gas occurrence state changes and the gas migration. Based on the influence of Baode Mine 81304 fully mechanized working face mining pressure law to gas pressure release migration, the influence of working face upper overlying strata movement law to ventilation volume, gas dynamic migration law of working face was analyzed, the relationship between working face wind drainage gas volume, wind volume and initial pressure of roof and periodic weighting interval as well as working face gas emission change law in recovery were got, which provided important reference for gas control in working face.
