摘要
在分析回采工作面瓦斯涌出特征的基础上 ,分别建立了回采工作面瓦斯涌出量与采深和工作面产量关系灰色预测 GM(1,1)改进模型 ,以预测工作面在不同采深与产量时的瓦斯涌出量。实际应用表明 ,预测模型可信 ,精度能满足要求。
On the basis of analyzing the character of the gas emitted from the mining face, the modified Grey predicting model GM(1,1) with amendments to the relationship among the gas amount, mining depth and coal output is respectively established. The amount of gas emitted from mining face could be predicted in case of different mining depth and coal output. The practical application demonstrates that the predicting model is reliable and its precision is enough to meet the practical usage.
