Abstract

According to seepage theory, the gas seepage from drainage hole along coal seam is studied by means of electrical simulation experiment. Meanwhile, the distribution rules of gas Pressure around drainage hole along coal seam and the effect condition of differ nt permeability coefficient on gas seepage are described in the paper. These results are useful for studying gas drainage in the coal seam and for Prevention of coal-gas outburst in mines.
