煤与瓦斯突出分形预测研究

以几个典型矿井为研究对象，应用分形几何理论和方法对地质构造进行定量描述，并分析其和煤与瓦斯突出危险程度的关系。确定了矿井断层网络分布的分形特征，初步建立了其分维持特征与突出之间的关系。研究结果表明，突出与非突出井田的断层分布均服从分形规律；井田吕断层分布的分维值与瓦斯突出之间存在着正相关关系等重要结论。为突出带预测提供了新的研究思路。

FRACTAL PREDICTION RESEARCH OF COAL AND GAS OUTBURST

Taking some typical coal mines as an object of study, the geological structure is quantitatively described and its relation with hazard extent of coal and gas outburst is also analysed using fractal geometry theory and method. The fractal feature of fault network distribution is defined, and relation between its fractal dimension character and outburst is initially established. The study results indicate that the fault distribution in both outburst and non outburst mine fields are all follow the fractal law, and there is positive correlation relation between fractal dimension of fault distribution and gas outburst. This investigation provided a new idea for the prediction of outbursts zones.
