| Abstract: | Take 3# coal seam of Wangyun Coal Mine for an example,the concept of critical pore scale is used to analyze the minimum range of aperture reached by pressurized water,the experiment is used to verify the effect of coal wetting raised by pressurized water.At last,based on the critical pore scale,the reasonable value of the pressure on coal seam affusion is put forward,the parameters are provided for coal seam affusion. |
