摘要:为准确预测煤与瓦斯突出灾害,作者以某矿井田为例,采用分形几何学手段研究了井田地质构造的分形特征,并将构造分维数与突出危险性作了对比分析;结果表明,该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量及突出危险性间存在正相关关系.

Fractal Research on Outburst Probeness Predictionin of Coal Mining Fields

Abstract:In order to predict correctly the disaster of coal and gas outburst, the authors take a coal mine as an example and study the fractal features of geology structures by means of fractal geometry.Besides, the authors compare and analyze structure fractal dimension and outburst proneness.It is shown that geological structures own fractal features, the complex degree of geology structures can be quantitively characterized by use of structure fractal dimension, and there is a positive correlation between structure fractal dimension and hazard extent of gas emission and outburst.
