为了正确预测媒与瓦斯突出的趋势和危险性,根据影响煤与瓦斯突出危险性分类的一些主要因素,应用物元理论建立了煤与瓦斯突出危险性分类与判别模型.给出了煤与瓦斯突出危险性评价的物元关联函数及物元关联度的计算方法;建立了适合可拓学理论的煤与瓦斯突出危险性等级分类标准;采用指标的综合权重,充分利用主观赋权法和客观赋权法各自带来的信息.应用证明此方法适合于煤与瓦斯突出危险性等级的评判和预测.
In order to correctly predict the trend and danger of gas and coal outburst, according to some main factors that affect the classification of coal and gas outburst, the matter classification and discriminant model of coal and gas outburst are established based on matter element theory.Considering coal and gas Highlighting the matter-element correlation function of risk assessment and the method of calculating the degree of matter-element correlation; establishing classification criteria for hazard rank of coal and gas outburst suitable for extenics theory; adopting the comprehensive weight of indicators, making full use of the subjective weighting method and objective The information brought by the empowerment method.The application proves that this method is suitable for the judgment and prediction of the dangerous level of coal and gas outburst.
