摘　　要：煤层注水难易性受多种因素影响,根据其影响因素,从中提取特征参数,从原始数据出发,引入粗糙集理论,将其运用在煤层注水难易程度诊断的特征参数优化中。采用可辨识矩阵和逻辑运算方法对决策表进行约简,删除其中不必要属性,降低了神经网络构成的复杂性。文章最后给出了属性约简结果。The difficulty grade of coal seam affusion is affected by many factors.Distill the attributes parameters according to the factors.;Apply rough set theory to the attributes optimizing of the coal seam affusion,use matrix arithmetic and logic operation to reduct decision-making table,delete some needless attritutes,reduce the complexity of the network..at last,the result of the attributes reduction is offered.
