摘要
文章应用灰色系统理论中的灰色综合评价方法，以某矿区８个煤层为例，选用瓦斯压力、垂深、瓦斯放散初速度、煤的破坏程度与硬度系数及作业方式６种因素作为聚类指标，选定灰类为不突出、一般突出、严重突出３种类别作为评价标准，借助于计算机进行运算，评价结果为预防煤与瓦斯突出提供了依据。
Abstract Based on Grey theory,this paper discusses the risk level of coal/gas outburst,with 8 coal seams in a coal field being used as samplesThere are 6 factors chosen as the accumulative classification indexes,namely gas pressure,mining depth,initial spreading velocity of gas destruction level of coal,coefficient of hardness and the mining practice adoptedCoalseams can be classified into three catalogs,namely no outbursttend,liable to outburst and highly liable to outburstThe assessment work,which is carried out by computers,provides useful in formation for precautions against coal/gas outburst
