摘　　要：运用Fry方法对承德地区已知煤矿点的空间分布形式做了分析,认为矿点整体走向和主要断裂带的走向一致。选择出露矿点较多的A地区,计算其矿点和断裂的分维值,将其与全区相比较,认为承德地区断裂带主要控制了煤层的走向,而煤的形成则受构造、古地理、古气候等因素的综合影响。Fry analysis was employed to study the spatial distribution patterns of known coal occurrences in Chengde region.The authors concluded that the orientation of all occurrences were in line with that of main fault zones.Zone A with more occurrences than other places was chosen to be compared with the whole region in terms of fractal dimensions of faults and known occurrences.It was concluded that the main fault belts played a controlling role in the orientation of coal layers,whereas the formation of the coal was affected by some factors like the structure,paleogeography and paleoclimate.
