摘要
A series of experiments,using X-ray diffraction, electronic microscope investigation and SEM observation,are carried out to investigate the microstructure characteristics of bump-prone coal. The samples are from four coal seams in two different coal mines,which compose of No.7,No.9 and No.12 coal seams in Zhaogezhuang mine and No.11 seam in Xinzhouyao mine.The microstructure parameters of coal are adopted to calculate the bump liability of
