摘要
介绍了三角模糊数的基本理论与方法,在煤与瓦斯突出综合假设的基础上建立了煤与瓦斯突出危险性评价指标体系,应用三角模糊数的综合评价法定量评价了煤与瓦斯突出的影响因素,得出了煤与瓦斯突出危险性评价指标中各个因素相对权重的大小为:D3>D7>D4>D2=D8>D9>D5=D6>D1>D10>D11,说明瓦斯放散初速度是煤与瓦斯突出危险性评价中最为重要的指标。
Introduce the basic theory and methods of triangular fuzzy numbers,a hazard evaluation index system of coal and gas outburst is established on the basis of synthesizing hypothesis,the influence factors of coal and gas outburst is evaluated quantitatively and comprehensively by the comprehensive assessment of triangular fuzzy numbers,the relative weight of various factors is obtained about evaluation index of coal and gas outburst.The results show：D3D7D4D2=D8D9D5=D6D1D10D11,namely that the initial velocity of gas irradiation is mostly important indexes in coal and gas outburst hazard evaluation,the method can provide theoretical basis for predicting and controlling disasters of coal and gas outburst.
