摘　　要：依据灰色系统理论,选取现场瓦斯异常涌出较为典型的4个致因指标,建立了工作面瓦斯异常涌出的灰色预警模型,计算了各样本指标的权系数以及所选取样本集的综合权系数,根据模型测度对工作面瓦斯涌出情况进行了预测。预测结果与瓦斯突出理论以及现场实际相一致,验证了该模型在采掘工作面瓦斯异常涌出预测应用中的可行性。Based on the gray system theory,the gray early warning model of gas abnormal emission at extracting coal face is established by selecting the more typical four causes of abnormal gas emission at scene. And index weights of each sample and the synthetic weight coefficient of selected sample has been calculated to predict gas emission situation at face according to model measure. The theory prediction and the actual site are consistent,and the model has been verified in gas abnormal emission forecasting.
