摘要
本文依据低温氮吸附试验的结果,探讨了下花园煤矿突出及非突出煤层在比表面积,孔隙体积及孔径分布等方面的差别,并分析了造成这种差别的原因,同时对该矿突出煤层出现的异常特征做出了解释。
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.
