瓦斯涌出严重程度分形预测研究

Research on Fractal Prediction of Severity of Gas Emission

为了研究瓦斯涌出严重程度与地质构造之间的定量关系,以某矿井田为例,采用分形几何学手段研究了井田地质构造的分形特征,并将构造分维数与瓦斯涌出严重程度作了对比分析。其结果表明:所研究矿井田地质构造具有分形特征,构造分维数能够定量地描述地质构造的复杂程度,构造分维数与瓦斯涌出严重程度之间存在正相关关系,分维值大于1.3的区域是有可能发生瓦斯异常涌出的区域。该研究成果对于高瓦斯矿井进行瓦斯区域预测研究具有重要的理论和实用价值。

In order to study the quantitative relation between the severity of gas emission and geologic structure, the fractal features of geology structures have been studied by means of fractal geometry, and the comparison of structure fractal dimension and severity of gas emission has been analyzed based on some mining field. It is shown that geolagical structures show fractal features, the complex degree of geology structures could be quantitatively characterized by use of structure fractal dimension, and there is a positive correlation between structure fractal dimension and the severity of gas emission. The zones where fractal dimension is 〉 1.3 are the zones where gas irregular emission could take place. The result shows important theoretical and practical value in predicting the gas zone in gas enriched mines.
