| 摘 要： | 灰色预测模型为矿井瓦斯涌出量时间动态数列的预测提供了一条新的途径。本文在对灰色ＧＭ（１，１）预测模型进行有关分析的基础上，提出了矿井瓦斯涌出量预测的ＧＤＭ模型，以进一步拓宽灰色预测的应用范围．利用该预测模型对一些矿井进行瓦斯涌出量的预测研究，均得到了较为满意的结果．

| Abstract: | The grey prediction model provides a new way for predicting the time dynamic numerical array of mine gas emission rate. Based on analyses of grey GM (1, 1)prediction model, and puts forward GDM prediction model of mine gas emission rate in order to expand the application scope of grey prediction. The obtained results in the prediction of gas emission rate in some minesare satisfactory. |
