| 摘 要： | 采用事故树分析法，对林华煤矿历次的煤与瓦斯突出事故资料进行了定性、定量分析，得出构造为林华煤矿煤与瓦斯突出事故的主控因素。运用分形理论对林华煤矿突出主控构造的特征进行分析，发现构造分布符合分形规律，信息维法比盒维法更能表征构造的分形特征。林华矿信息维数达到或超过一定数值的范围内，应采取抽放瓦斯等综合防突措施，加大防突力度。

| Abstract: | FFA was applied to conduct the qualitative and quantitative analysis the structure is the main controlling factor of the accidents. Fractal theory was used to analyze the characteristics of the master structure and it was found that the structure distributions accorded with the law of fractal. The information dimension was better than the box-law dimension to perform the structure fractal characterization. If the information-dimensional number reach or exceed the range of a certain number, the measures such as gas drainage and so on should be taken to increase the intensity of outburst prevention. |
