GM(1,1)模型在小屯矿煤层瓦斯抽采量预测中的应用

Application of GM(1,1) Model in Prediction of Gas Drainage

针对小屯矿6中煤层瓦斯抽采实际,采用灰色系统残差修正GM(1,1)模型进行了瓦斯抽采量预测,并建立适合于该矿的瓦斯抽采量预测模型,其结果表明:利用灰色系统GM(1,1)模型预测矿井瓦斯抽采量是可行的且精度较高。

Based on gas extraction practice in 6 ~ coal seam in Xiaotun Coal Mine, the Grey model-GM （1, 1）was adapted according to grey system theory to predict gas extraction amount, and gas extraction amount prediction model was established. The result shows that using gas extraction amount prediction model to forecast gas extraction amount is feasible and high precision.
