摘要 以评估煤与瓦斯突出的危险程度为目的,以突出宏观显现对煤与瓦斯突出危险数据库进行分类,以三维立体图展现突出危险与瓦斯压力、放散初速度、坚固性系数和破坏类型。建立了突出危险灰色关联度模型,结果表明:煤体破坏类型与坚固性系数是作用煤与瓦斯突出的关键指标,主要导致在巷道或采面发生的突出;瓦斯压力与放散初速度是影响煤与瓦斯突出的控制指标,钻孔突出多数由瓦斯参数主导突出过程。 To predict the coal-gas outburst risk degree rate in coalmine,the outburst macro appearance classified the coal-gas outburst risk data,the relationship between the outburst risk and the gas pressure,the radiation initial velocity,the sturdiness coefficient and the damage type respectively were seen in the different 3D stereogram.The outburst risk grey correlation model from similarity and proximity,he sturdiness coefficient and the damage type were the key indicators and happended in the heading face and the coal face,the gas pressure,the radiation initial velocity were the control indicators and happened in the drilling.
