摘要
煤与瓦斯突出是含瓦斯煤岩体发生的极其复杂的动力现象,属于复杂非线性动力系统在时空演化过程中的灾变行为,是影响煤矿安全生产的主要灾害之一。探索煤与瓦斯突出现象背后的规律性,对预防突出具有非常重要的意义。文章首先采用灰色关联分析方法对预测指标及众多影响突出因素进行样本分类,建立指标与因素映射量之间的关系,确定各映射量影响因子的大小,然后结合数理化理论建模,模型较好的体现了煤与瓦斯突出危险性与各影响因素之间的量化关系。最后通过实例论证,得到了较高的预测可靠性。
Coal and gas outburst are the extremely complex power phenomena which occurs in the coal rock include gas, it belongs to the complex non -linear dynamic system in space and time evolutionary process cataclysm behavior, one of main disasters affect coal mine safety production. Explore coal and the gas outburst phenomenon regularity, to prevents coal and the gas outburst have the extremely significance. The paper first uses the gray connection analysis method to forecast the target and the multitudinous influence outburst factor carry on the sample classification, establishes the volume mapping relations between the index and the factor, determined the size of each mapping quantity influence factor, then union math theory modeling, the model has manifested quantification relations between each influence factor of the coal and the gas outburst risk. Finally through actual validation, the prediction is very reliability.
