The gasleakage model commonly used in China at present is only suitable for small flow speed and short time of leakage and can't well describe long time of leakage and big change of flow speed.
Based on the new viewpoint of the interaction between solid deformation and gas leak flow, the mechanism of gasleakage in double deformable coal seam can be understood.
应用煤岩体变形与煤层气(瓦斯)越流相互作用的新观点,研究了双层系统煤层气越流运移的机理。

The leakage area, inflator gasflow rate and dimension of side airbag on a passenger car were optimized.
