【Abstract】 The paper tests the change of flow and pressure of around the boundary during breaking coal area by means of osmoscope,and concludes the inner flow motion laws of crushing object and the relation ship to surrounding pressure,thus an experimental base for further study of the flow dynamics of breaking coal seam can be established.更多还原
