It is shown that geological structures are of fractal features，and there is a positive correlation between fractal dimension of structure and danger extent of gas outburst over the three scales. The results indicate that multi-scale assessment of outburst tendency of coal and gas can be made based on fractal measurements independently or supplemented by other assessing methods.
