| Abstract: | In this paper, the disparities in surface area of unit weight, volume of porosity, aperture distribution, etc. between the outburst coal seams and non-outburst coal seams in Xia Huayuan Colliery are discussed, and the reason for oreating the disparities is analysed according to the results of the nitrogen adsorption test under low temperature. The abnormal features of the outburst coal seam in the colliery are also interpreted. |
