| 摘 要： | 采用分形几何学手段，从煤田、井田、采区等3个尺度上，研究了地质构造的分形特征，并将构造分维数与瓦斯突出危险性程度作了对比分析。结果表明，在不同尺度上，地质构造均具有分形特征，构造分维数与瓦斯突出危险性间存在正相关关系，为煤与瓦斯突出分形预测研究提供了初步的理论基础。 |

| Abstract: | The fractal feature of geological structure and the relation between fractal dimension of structure and danger extent of gas outburst are analyzed in three scales of coal field,mining area and stope,respectively. 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. |
| Keywords: | mining engineering geological structure fractal dimension coal and gas outburst prediction |
