Abstract With the increase of pore pressure，coal permeability changing in V shape. The critical pore pressure is the pore pressure corresponding to the minimum permeability. Results show that both sides of critical pore pressure are two different physical mechanisms percolation process. When pore pressure is less than critical pore pressure，flow mainly to slippage effect. The relationship between slip coefficient and confining pressure shows a V shape change. When pore pressure is greater than critical pore pressure，the gas flow in a linear flow-based. The relationship between reciprocal of permeability and square of pore pressure is linear. This study is important for a correct understanding from the mechanism of low permeability coal reservoir flow process.

Key words： mining engineering slippage effect low permeability coal seam seepage pore pressure
