矿井煤与瓦斯突出预测的物元模型方法

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.

An Matter-Elements Model and Its Application to Dangers of Coal and Gas Outburst Mines

In order to predict the potential dangers of coal and gas outburst accurately, applying the Matter—Elements Model,classify the dangerous grade of coal and gas outburst mine for three grades.According to rhombic thinking mode and the extension of matter element,the multi-index and hierarchical system of Dangers of Coal and Gas Outburst Mines was built and gives the method determining the synthesis weights of indexes that include both subjective favoritism and objective information Qualitative knowledge and quantitative data need to be integrated.Quantitative change and qualitative change all need be reflected in the assessment results of d dangers of coal and gas outburst Matter-element model was constructed to assess dangers of coal and gas outburst by matter-element transform.It has theoretical significance and practical value in perfecting the safety management in coalmine.
