断层分维特征与瓦斯突出的关系

Study of the Fault Fractal Feature and Outburst

应用分形几何学的原理和方法对具有代表性的多个矿区井田内的断层分布特征及其与突出的关系进行了研究．研究结果表明，井田中的断层分布服从分形规律，断层的分维值和煤与瓦斯突出之间存在相关关系，应用断层分维值分析和认识突出与断层构造的关系是进行突出预测的一种有效方法．

By means of fractal geometry, a primary research has been conducted in several coal mines with emphasis on the fractal features of fault networks and their relations to the proneness of outbursts. The results showed that fault distribution obeys fractal law, and that fault fractal dimension is closely related to coal and gas outbursts. This study also indicated that, as far as outbursts prediction is concerned, it is beneficial and effective to conduct fractal analysis of the relationship between fractal dimensions of fault networks and proneness of outbursts.
