| Abstract: | The coal cleat pattern in the Kushiro coalfield, Japan, shows some analogy to isolated straight joints. The characteristics of a coal seam in the Kushiro coalfield and its relevant cleat system are introduced. The influence of confining pressure change and coal cleat on gas permeability is studied by experiments. |

| Keywords: | Coal cleat gas permeability confining pressure |
